1 INTRODUCTION 1.1 Description of the Project 1.1.1 The Document
This document is the final report of the project: The Study of Traffic Accident Costs in Thailand which commences on the 1st of September 2005. Chapter 1 gives a description of the project, the commitment of the Thai government in dealing with traffic accidents as manifested in Prime Minister Thaksin Shinawatra’s letter to the WHO which was published in the WHO 2004 World report on road traffic injury prevention, and the traffic accident situation in Thailand. Chapter 2 presents the review results of the available methodologies for determining traffic accident costs. The review was conducted at national and international levels. In Chapter 3, the methodologies were reviewed. Chapter 4 presents the pilot case study for five province. Chapter 5 describes the study traffic accident cost in Thailand. Chapter 6 gives the computer programme for calculating traffic accident cost and Chapter 7 describes the conclusion and application.
1.1.2 Objectives • To detail a sound and comprehensive method of calculating traffic accident costs
which enables values to be regularly updated. • To enable the application of cost benefit analyses traffic accident reduction
projects. • To identify actual traffic accident costs and the burden placed on society for use
in raising the awareness of policy makers and the public. 1.1.3 Scope of Work The following activities together with detailed reports outlining the results and recommendations that result from the study are required. Stage 1 (10 months) • Review available data and methodologies for determining traffic accident costs
both nationally and internationally. • Recommend the most appropriate method for use in Thailand taking into
consideration available data, economic realities, practicability and other local issues and constraints.
• Implement a case study using the recommended method in Khon Kaen Province. This will be used as a prototype for other Provinces and must be implemented within 10 months of the commencement of the study.

Stage 2 (14 months) • Implement a similar study in at least 3 other Provinces to confirm applicability of
method across all of Thailand. • Produce estimates of costs for all severities of crash and injury for rural and urban
crashes and other categories of crash as appropriate. Produce a gross cost estimate for the country as a whole including and allowance for under-reporting and definition issues.
• Produce guidelines and simple software to enable annual adjustments and less frequent recalculations of crash costs in the future. The guideline should include an example of the application of the costs for use in cost-benefit analysis of a road safety scheme.
• Establish a training/education regime that allows the transfer of knowledge, technologies, findings and issues related to the recommended method. It is expected that a minimum of 2 formal training seminars will be held each year.
• Examine and make recommendations on how the private sector can contribute/assist in the implementation of the method.
Consideration of the following factors shall be included in completing the above activities.
• The human capital approach shall be used. • The costs shall include at least the following.
- Property damage costs - Emergency services costs (police, doctors) - Insurance services costs - Judicial system costs - Vehicle repair costs - Loss of productivity - Hospital costs
• Khon Kaen Central Hospital shall be used as the pilot hospital in the first year of the project.
• Account shall be taken of the priority accident locations in evaluation of traffic safety improvement cost benefits.
Timing The project starts on 1 September 2005 will be completed in August 2007 runs for 24 months.

1.2 Prime Minister Thaksin Shinawatra’s Letter to WHO The letter of Thailand’s Prime Minister addressing road accident problem in the country was written for inclusion in the WHO 2004 World Report on Road Traffic Injury Prevention which was launched on World Health Day 7 April 2004. The Prime Minister stated the strong commitment of the government in dealing with the problem. Below is the full text of the letter.
In Thailand road accidents are considered one of the top three public health problems in the country. Despite the Government’s best efforts, there are sadly over 13 000 deaths and more than one million injuries each year as the result of road accidents, with several hundred thousand people disabled. An overwhelming majority of the deaths and injuries involve motorcyclists, cyclists and pedestrians. The Royal Thai Government regards this problem to be of great urgency and has accorded it high priority in the national agenda. We are also aware of the fact that effective and sustainable prevention of such injuries can only be achieved through concerted multisectoral collaboration. To deal with this crucial problem, the Government has established a Road Safety Operations Centre encompassing the different sectors of the country and comprising the government agencies concerned, nongovernmental organizations and civil society. The Centre has undertaken many injury prevention initiatives, including a “Don’t Drink and Drive” campaign as well as a campaign to encourage motorcyclists to wear safety helmets and to engage in safe driving practices. In this regard, we are well aware that such a campaign must involve not only public relations and education but also stringent law enforcement measures. The problem of road traffic injuries is indeed a highly serious one, but it is also a problem that can be dealt with and prevented through concerted action among all the parties concerned. Through the leadership and strong commitment of the Government, we are confident that we will be successful in our efforts and we hope that others will be as well.

1.3 The Situation of Traffic Accidents in Thailand 1.3.1 General
Economic growth in Thailand has brought about an expanding network of roads and an increasing number of the driving public. The growing number of vehicles on the roads, in turn, have corresponded to the significant increases of road crashes in recent years. In 2002, the total national economic losses due to road accidents are estimated to be 140,000 million Baht or approximately 2.13 percent of the GDP. Road crashes have been a major cause of death and injury in Thailand. Table 1.1 shows traffic accident statistics for the country between 1987 and 2005 The number of road crashes can be seen to rise from 24,132 cases in 1987 to 102,610 in 1994; drop to 67,800 in 1999 and surge to 122,040 in 2005, in line with the economic recovery. Data of accident occurrences and number of fatalities are plotted in Figure 1.1 Fatalities were on an increasing trend starting from 8,589 in year 1987 to peak at 16,727 (1.91 deaths per hour) in 1995. After peaking, the number of fatalities declined to 12,858 (1.47 deaths per hour) in 2005. Table 1.1 : Traffic Accidents in Thailand from 1987 to 2005

As shown in Figures 1.5 to 1.7, the rates of accident and injury occurrence was on a decreasing trend from 1995 to reach the trough in 2000 before rising in the subsequent years. The fatality rate, however, has been decreasing since 1995, its graph showing a nearly constant trend in recent years. 1.3.3 Road Crashes during Songkran and New Year Songkran and the New Year are the two major festival seasons in Thailand for Thai families to unite and celebrate. The occasions give rise to spikes of vehicular trips which in turn have led to increasing accident rates and fatalities. • Road Accidents during Songkran Festival Songkran is celebrated from April 8th to April 17th in years 2005 and April 7th to April 16th in years 2006. Table 1.4 compares the number of deaths and injuries during the said period for the years 2005 and 2006. Accident fatality peaks on April 13rd for both years. Injuries and deaths in 2005 were 2,817 and 79 respectively. Similar statistics for 2006 were down to 1,161 and 89, which represents a 58.8 percentage reduction in injuries from the previous year. This significant drop in of accident and fatality rates, shown in Figure 1.8, has been attributable to an awareness campaign implemented by the government which aimed at reducing road crashes during the Songkran festival.

1.4.2 Definition of Crashes A fatal crash is one in which one or more persons are killed as a result of the accident, provided death occurs within 30 days (Vienna Convention 1968). A serious crash is one in which there are no deaths, but one or more persons are seriously injured. A serious injury is defined in the UK as either one for which a person is detained in hospital as an 'in patient', or if any one of the following injuries are sustained whether or not he or she is detained in hospital: fractures, concussion, internal injuries, crushing, severe cuts and lacerations, or severe general shock requiring medical treatment. In the UK this category includes deaths occurring after 30 days. A slight crash is one in which there are no deaths or serious injuries, but a person is slightly injured. This will be an injury of a minor character such as a cut, sprain or bruise. A damage only crash is one in which no one is injured, but damage to vehicles and or property is sustained.

2 REVIEW OF METHODOLOGIES
This chapter reviews methodologies for determining the cost of road crashes. Section 2.1 review the methodologies used in various countries, and section 2.2 those used in Thailand.
2.1 International Experience in Estimating Crash Costs Road crashes are a major cost in all communities. Crashes not only cause death and injuries to people but also have other social and economic costs including grief, hardship, property damage and government infrastructure. While it may be difficult in some instances, it is necessary to place an economic (monetary) value on the costs of road crashes. It is necessary because it allows management of this issue by assisting in directing limited resources into areas where they will have the most effect.
The development of road crash costing systems has been ongoing in the developed countries. These systems are comprehensive and do allow for not only best safety improvement options to be developed for limited budgets but also to allow better assessment of the cost effectiveness of intervention programs that have been implemented.
The systems have been based on either the human capital or willingness to pay approaches to take account of the fatality and injury part of the total crash cost.
The Human Capital Approach (HC) is based on the value of the person in the economic production process and that to prevent a crash will lead to saving the potential loss in productivity incurred when a person is killed or injured.
The Willingness to Pay Approach (WTP) is based on an individual’s assessment of their crash risk and what they are prepared to pay to reduce or minimize this risk.
This study uses the human capital approach. The approach has been widely used in developing countries as it is relatively simple to calculate compared to the WTP approach which is commonly used in developed countries. A recent study of economic costs of road crashes summarizes the approaches used in a number of countries (See Table 2.1).
The UK Department of International Development (DFID) has recently published guidelines for estimating the cost of road crashes in developing countries (DFID Project R7780 2003). In the guidelines, the HC method was recommended for use in developing countries, with sums added to reflect ‘the human costs’ which take account of pain, grief and suffering of the people involved. The main cost components in the Human Capital method thus include: • Property damage. • Administration costs. • Lost output. • Medical costs. • Human costs and Effect on the poor.

In examining how various countries have approached the development of a system to calculate crash it is very clear that the major limitation encountered is data availability and data integrity. Therefore to look for a guiding framework for the development of a road crash costing system for Thailand it has been decided to look closely at a system operating in a highly developed country then examine the issues that are relevant to Thailand.

Example Road Crash Cost System
The Australian road crash costing system will be considered as the desired framework. This system is typical of other developed western countries and uses the human capital approach to value the fatal and injury costs. Much of the base information is drawn from “Road Crash Costs in Australia”, Report 102, BTE Canberra 2000.
The Australian crash cost system has several components. These are grouped under three categories:
• Human costs • Vehicle costs • General crash costs The human costs category examines several areas and proposes a method for establishing a monetary value for each. These areas are:
• Value of lost labour • Quality of life • Medical costs • Long term care • Coronial costs • Premature funeral costs • Legal costs • Correctional services (prisons) costs • Workplace disruption and staff replacement In the vehicle costs category the following areas are considered:
• Repairs costs • Towing • Time lost due to vehicle unavailability The general crash costs category includes broader areas of:
• Non-vehicle property damage • Police costs • Costs of fire services • Insurance administration • Travel delay costs It is a comprehensive system covering a broad range of direct and indirect costs that can be attributed to road crashes. It is dependent on a wide range of data that needs not only to be accurate and current but also available on an ongoing basis. While this paper looks at the Australian system as the desired framework, it should be recognized that there are many similar systems in Europe, e.g. Germany and Denmark.

It is recognized that the data/information for this system may not be available in many developing countries but by adopting this type of framework, more elements may be added to a category when the necessary data becomes available. To better understand the Australian crash cost system each category will be examined in more detail and where possible examples from developing countries road crash cost systems will be discussed to show how the principles of the Australian system have been met.
Road Crash Database The fundamental building blocks for a road crash cost system are contained in the road crash recording systems. The severity, type, location, contributing factors, injuries sustained, time, date, gender and road conditions are some of the elements of a good road crash recording system. Many of these are required if road crash costs are to be determined on a national basis. In Australia the recording of fatalities from road crashes is at a high standard with data integrity and timeliness both excellent. The level of confidence for injury and property damage data is less although it remains high compared to that available in developing countries. The important principle to take from the Australian system is that the effectiveness of any road crash cost system is extremely dependent on a stable, accurate, broad and timely road crash database.
2.1.1 Human Costs Value of Lost Labour This is calculated on the loss of working time that is attributable to the road crash. For a fatality or permanent incapacity this is derived from the amount of working life that a person would have been expected to have based on gender specific life expectancy data. This can be equated to average wage rates by gender and use to calculate a monetary value. This amount is then discounted back to the present day value for inclusion in the system. There are various economic views on how these values are calculated but the principles remain the same. There is also a method for calculating a value for the loss of a person who works in the home or on voluntary community service. This is an added complexity.
The issues to note from this message is the use of average wage rates which is an appropriate measure in an egalitarian society like Australia but may not apply in developing countries where wage systems are less structured and more skewed.
Quality of Life The loss of quality of life is an acknowledged but difficult to define result of road crashes. The human capital method does not traditionally try to estimate on economic value for this. The Australian system uses court awards and settlements as a measure of the quality of life. This has significant problems relating to consistency and philosophically what is taken into account in the Court deciding on an amount. Additionally there are upper limits placed on the amount that can be awarded in some jurisdictions. There are many ways the loss of quality of life can be calculated, all with their strengths and weaknesses. Proponents of the WTP approach advocate the use of this approach to value the loss of quality of life. In Great Britain, this component is calculated as a percentage of the total fatal cost, the value of which was shown in the Table 2.2 below.

Table 2.2 : Human Costs (reflecting pain, suffering) as a Percentage of the Total Fatal Crash Cost Great Britain
Source: DFID Project R7780 2003
Other European countries use different values to reflect pain, grief and suffering in the human costs. These values are given as a proportion of the total fatal casualty cost for a crash as shown in Table 2.3. In its 1995 Overseas Road Note 10: Costing Road Accidents in Developing Countries, the UK Transport Research Laboratory suggested that the following percentages should be added to reflect pain grief and suffering: • 28% of total costs for a fatal crash. • 50% of total costs for a serious crash. • 8% of total costs for a slight crash. • 0% of total costs for a damage only crash. Thailand has used such values in its 1997 Road Safety Master Plan Study.
Medical Costs
This includes all medical treatment, transport to and from hospitals and costs associated hospital based with longer term care and rehabilitation. This information is dependent on knowing the type and severity of injury and the location of the treatment. Australia also considers three types of injury in determining costs fatality serious injury (hospitalization) and minor injury (out patient). The methodology calculates average costs for each of these injury types so that can be applied to the data obtained from the comprehensive road crash data base. Long Term Care This involves the costs associated with the long term care of crash victims outside of the hospital system. The methodology uses numbers of people with disability derived from census data with average cost of care of people as measured by government funding for care institutions per capita. This cost area will be difficult to measure in developing countries where the long term care is principally a family responsibility.

Coronial Costs In Australia all road deaths are investigated by the Coroner and this item takes into account the costs associated with these investigations. Premature Funeral Costs Unexpected death caused by a road crash can create a financial burden on families due to the high cost of funeral and the general lack of savings for these events. This cost area looks at the extra cost caused by the premature nature of the event which may force borrowings or the use of savings that were to be used for another purpose. This item may not be easily quantified in Thailand.

Court Costs The legal or court costs included in this area are those arising from insurance claims and those arising from criminal action being pursued. These costs are deduced from insurance company statistics and from police prosecution records respectively. This item may not be easily quantified in developing countries.
Correctional Services Costs These are the cost of imprisonment, periodic detention or community service orders relating specifically to imprisonment for road crash related misdemeanors.
Workplace Disruption & Staff Replacement The relates to the loss of productivity costs for people returning from road crash injury and the costs of overtime or temporary staff required while injured person is unable to work. Measurement of this is difficult in Australia and may be more so in developing countries.
Summary There are many cost areas considered in the Australia system and not all may be applicable in developing countries. They do however provide a sound framework to consider the type of road crash cost system that best suits the local conditions and particularly data availability. To assist on looking of priorities the following Table 2.4 showing the relative contributions to overall human costs made by each of these areas. This will assist in the setting of priority areas for cost evaluation.

2.1.2 Vehicle Costs Repair Costs These costs are dependent on many factors including severity of crashes, type of vehicles involved and location of repair shop. Australian data is obtained from insurance records and allow for all of the critical factors. Linking these costs to type of crash based on fatal, serious injury and minor is more difficult as insurance data does not include information on injuries involved. It is likely this will be more difficult to link in a developing country situation.
Towing These costs relate to moving the vehicle from the scene and data is directly available from insurance companies. The linkage to the crash type remains difficult. Time Lost due to Vehicle Unavailability
Vehicle unavailability is a cost, in addition to the direct cost of repairs. For a commercial operator, e.g. taxi this downtime may mean lost business, employee time wasted, or work delayed or cancelled. For a private owner, downtime may mean inconvenience due to a need to use public transport, lost leisure time, or some abandoned trips. It is not feasible to value these individual losses, but the maximum and minimum losses expected due to vehicle unavailability have been estimated in terms of hiring cost of a replacement vehicle and the average total cost of owning the vehicle over the period it is unavailable.
It is noted that many cases of minor damage need not be repaired immediately, or at all. The owner can reduce the cost of unavailability by choosing a convenient time make the repair. 2.1.3 General Crash Costs
These are the costs that are not directly related to the level of severity of the crash.
Non-vehicle Property Damage
Damage to property such as traffic signals, traffic signs or other street furniture, guard rail is common outcome of road crashes. Estimation of the value of non-vehicle property damage requires knowledge of what is being damaged and how often. In Thailand road authority such as the Department of Highways has a good statistics on the cost of damage to the Department’s property. Police Costs Information on police response, attendance and investigation times is required in order to make estimation of the average time spent on specific crash-related police activities. In Australia, these include administration of reported crashes, notification of next of kin, coronial attendance and investigation, crash investigation and road audits.

Cost of Fire Services
In fatal and serious crashes and whenever there is a need for their specialized fire control, hazard management and rescue assistance, the fire crew will attend and remain at the scene of a crash until it has been cleared and there is no further hazard to motorists or to the general public.
Insurance Administration In providing insurance cover for vehicles, the insurers incur expenses known as underwriting costs, which are the costs of administering claims. . Travel Delay Costs
Road crashes can result in travel delays to other motorists, particularly in the urban area. Such delays impose costs as the time lost queuing in traffic has a productive value. In estimating the cost of the delay, it is necessary to know values on travel time saved and lost. Values of 44 to 68 per cent of the wage rate for travel time lost and 35 to 41 per cent for travel time saved were proposed and adopted in the Australian method.
Summary
The various component of general crash costs are summarized in Figure 2.1

2.2 National Experience in Estimating Crash Costs Research Work on Economic Losses of Road Accidents in Thailand. There are quite a number of research projects on the analysis of economic losses from road accidents in Thailand. Virtually all of these have adopted the human capital approach in estimating the losses. Work at the national level includes Direk Patamasiriwat (1994), R. Tosutho (1997), Angsana Boontam (2001), Worawate Suwanrada (2005), and Paramet Luathep and Yordphol Tanaboriboon (2005). Studies limited to road accidents in Bangkok are Prapee Komnamoon (1979), Chareonrat Promglam (1998), Rungnapa Kradang-Nga (1999), and Wanapa Sumiratana (1996). Other studies, such as Watana S. Chanchareon et. al. (1993) and Supachai Kunaratanapruek et. al. (1995), focus on medical costs of road accidents. It is possible to classify the methods used in these studies according to the three types of losses, as follows. (See Table 2.5 for summary of the time period, the level of data, and the type of losses in these research studies.) 2.2.1 Lost Output The opportunity cost of lost output from road accidents can be divided into 3 groups: • Lost output due to death, • Lost output due to injury (full recovery or continuing disability), • Lost output among care takers of the injured and the disabled. (See summary of the methods used in estimating lost output due to death in Table 2.6, and that of the methods used in estimating lost output due to injury and care taking in Table 2.7)
Most research projects on road crash costs in Thailand include only lost output due to death and injury of the victims, and do not take into account lost output due to care taking of the injured. However, there are three studies [Direk Patamasiriwat (1994), R. Tosutho (1997), and Worawate Suwanrada (2005)] which attempt to quantify the loss of income of those who carry the burden of caring for the disabled.
In estimating lost output, most researchers use the same principle by examining losses in terms of time and income which should have been earned during the remaining working life of the dead. In the case of injury, income losses are estimated during and after the hospitalization period, both for the injured and their care takers. Therefore, it is necessary to make projections of future income for those affected by accidents. The methods of income projection are elaborated clearly in Prapee Komnamoon (1979), Direk Patamasiriwat (1994), R. Tosutho (1997), Worawate Suwanrada (2005), and Angsana Boontam (2001). The methods used differ from one another. Worawate Suwanrada (2005) calculates foregone income from the “wage function” which relates wage income to age, and is estimated based on the data from a work status survey by the National Statistical Office. R. Tosutho (1997) estimates average income classified by age from the “earning function”, while Direk Patamasiriwat (1994) derives average income classified by age and gender from a set of survey data by the National Statistical Office.

There are also differences in income growth rate and discount rate which is needed to convert future values into present values. Direk Patamasiriwat (1996) sets the average income growth and the social discount rate at 5.5% and 4% per year respectively. Prapee Komnamoon (1979) uses the discount rate of 12% per year, while Worawate Suwanrada (2005) allows income to grow at 6% per annum, and discounts any future values at 3% per annum.
2.2.2 Medical Expenses
Medical service for accident victims can be divided into two periods: emergency medical service before reaching hospitals, and hospital care. (See summary of estimation methods for medical costs in Table 2.8.) Direk Patamasiriwat (1996) studies pre-hospital medical costs by relying on data provided by three hospitals in Bangkok – Rachawithee, Wachirapayabarn, and Bangkok. He defines “pre-hospital care” as the emergency preliminary medical service provided at the scenes of the accidents, including delivery to the hospital.
Medical cost can be analyzed from 2 viewpoints: medical expenses actually paid by patients to hospitals, and the actual cost incurred by hospitals. Prapee Komnamoon (1979) distinguishes two groups of patients: out-patients who are slightly injured and not required to spend a night in hospital, and in-patients who sustain medium to serious injuries and are required to be hospitalized for 3 – 80 days. Prapee uses data from Siriraj Hospital, Ramathibodhi Hospital, and Central Hospital to estimate the economic cost of medical care in road accidents. It should be observed that Prapee Komnamoon (1979), as well as Direk Patamasiriwat (1996) and Paramet Luathep and Yordphol Tanaboriboon (2005) rely on data from only state-owned hospitals, while Watana S. Chanchareon et. al. (1993) utilizes random samples from both state-owned and private hospitals for their medical cost estimation. R. Tosutho (1997) tries to detect the trend and finds that medical cost for in-patients in state-owned hospitals increased during the 1991-1995 period.
2.2.3 Property Damage Cost and Other Costs
Most road accidents involve damages to public and private properties including vehicles, roads, and traffic signs and equipment. (See summary of estimation methods for property damage and other costs in Table 2.9) Prapee Komnamoon (1979) classifies property into vehicles and other property, and uses questionnaire-based survey data in 1976 for Bangkok to estimate vehicle repair cost, insurance-related cost, and time cost of other third-party individuals. He finds vehicle damage cost to be higher than other property costs. Direk Patamasiriwat (1994) and R. Tosutho (1997) estimate property damage cost both for the private and public sectors.
Besides the costs mentioned above, road accidents entail other costs, such as police and judicial administrative cost, and insurance administrative cost. One type of cost whose valuation is the most difficult of all, is “pain, grief, and suffering” experienced by the victims and their loved ones – generally called “human cost”. Paramet Luathep and Yordphol Tanaboriboon (2005) try to include these other costs, including emergency medical service cost. They follow the method recommended by the Transport Research Laboratory (1995) and modified by Mohan (2002) in setting human cost as a percentage of total accident cost : 20% in the case of fatality, 50% in the case of serious injury, and 1% in

the case of slight injury. Worawate Suwanrada (2005) also includes the human cost as part of the economic loss of accidents, and he also uses the Mohan modified TRL recommendation as that adopted by Paramet Luathep and Yordphol Tanaboriboon (2005). Worawate Suwanrada (2005) also examines court decisions and concludes that the compensation amounts for car accident victims granted by the Thai court cannot be used as the “shadow price” for human cost.

2.3 Summary The methodologies for determining road crash costs have been reviewed from both international and national experiences. Cost components that are common in most of the methods reviewed are:
• Loss of productivity ( due to death, injury, disability of crash victims and their carers)
• Property damage costs - Vehicle costs ( repair, towing and vehicle unavailability cost) - Non-vehicle costs (public infrastructure e.g. guard rail, traffic signal poles)
• Medical and Hospital costs • Emergency Medical Services costs

• Police costs ( emergency response, site investigation, follow-up and administration) • Insurance services costs • Judicial system costs
The UK Transport Research Laboratory (1995) has recommended the use of fixed percentages to add to the total costs of a crash, depending on the severity to reflect the human cost of pain, grief and suffering. For example, 28% for a fatal crash, 50% a serious crash and 8% a slight crash. Thailand has used these values in its 1997 study of road accident costs. A number of countries have used similar values modified from the TRL recommendation including the latest two studies. In the present study, these values will likely to be obtained from interviews with experts and Politicians.
The Australian costing has included funeral costs, correctional services (prisons) costs, coronial costs and workplace disruption and staff replacement costs in its human costs category; costs of fire services and travel delay costs in the general crash costs category. For Thailand situation, a significant component, the emergency rescue costs has been added. These are the costs born by private volunteer foundations which play an important role in the rescue of crash victims or assisting police/medical personnel at the scene of the accident. The present study will thus cover the following cost components:
• Loss of productivity ( due to death, injury, disability of crash victims and their carers)
• Quality of life costs • Medical and Hospital costs • Emergency Medical Services costs • Long term care • Property damage costs
- Vehicle costs ( repair, towing and vehicle unavailability cost) - Non-vehicle costs (public infrastructure e.g. guard rail, traffic signal poles)
• Police costs ( emergency response, site investigation, follow-up and administration) • Insurance services costs • Judicial system costs • Emergency rescue costs, and • Travel delay costs

3.2 Human Costs Category The human costs category consists of the loss of productivity costs, quality of life costs, medical care costs, emergency medical services, and long term care costs. 3.3.1 Loss of Productivity Costs The opportunity cost of lost output from road accidents can be divided into 5 groups: 1) Lost output in terms of income loss from fatality 2) Lost output in terms of income loss from disability (both work and non-work) 3) Lost output t in terms of income loss from serious injury (in-patients) 4) Lost output in terms of income loss from slight injury (out-patients) 5) Lost output in terms of income loss involving those relatives and friends who take care
of the injured and the disabled Estimation method for calculating the value of lost output In estimating the value of lost output due to road accidents, we start with the estimation of a wage function which is in the form used in Worawate (2004) and panel data between variables on worker characteristics (age, sex, education, geographical location, and workplace) in each province. These data are obtained from a quarterly survey on work situations for the third quarter of 2004. The wage function is as follows. 2

where MALE : 1 = female, 1 = male MARRIED : 1 = others, 1 = being married
Other dummy variables: 0 = No, 1 = Yes subscript ij is observation j of province i
The estimation use Generalized Least Square method with fixed effect regression model. The fixed effect term or the constant term ( 0iα ) are different in each province i. However, the social and economic structures are different between regions of the country. Therefore, we estimating a wage function for workers in each province by grouping provinces into regions as the Central (except Bangkok and vicinity), Bangkok and vicinity, the North, the Northeast, and the South. From the results of estimation we obtained a wage function for each province. A wage function with only age as an independent variable can be constructed specifically for workers by substituting the value of 1 in the sex variable for a male function and 0 for a female function. And all other variables assume their average values. Then, we have the natural logarithm of monthly wage ( ˆln iWage ) for different age groups in average cases, as shown in Equation 2

Notes: 1) Accident victims who are disabled and can still work are assumed to reduce their working
efficiency down to 30% of the previous level, according to Worawate (2004) 2) The percentages of 33.5% and 4.2% used in cases of caring for the disabled are derived from Survey on Disabilities and Handicap in 2002 by the National Statistical Office.
Data and sources of data for calculating the value of lost output In estimating the value of lost output of road accident victims, we use the following data. 1) Data for Estimating Labor Hour and Wage Functions Data on worker characteristics (age, sex, education, geographical location, and workplace) and wages are necessary for estimating a wage function and foregone income. These data are obtained from a quarterly survey on work situations for the third quarter of 2004. 2) Data for Estimating Lost Output
These data consist of:

(5) The length of hospitalization period includes the number of days of medical treatment in hospital and the number of recuperating days at home. Wannarha Sumirattana (1996) finds that, the number of recuperating days are roughly equal to the number of days of medical treatment in hospital. Following this finding, we adopt the assumption that the number of days of hospitalization for serious injuries is twice the number of days of medical treatment in hospital.

(6) Foregone Income Based on the data obtained from a quarterly survey on work situations for the third quarter of 2004, we estimate the wage function which are in the form used in Worawate (2004). However, the unit of the working hour variable (PLABHOUR), which is in hours per week in Worawate (2004), is in hours per month in this study.∗
The wage function shows the relationship between wage and age, and was used I determining the future income of a dead victim. For instance, given that the wage function being Ft(A), where t is the present year and A is the age of a worker. When a person dies in a car accident at the age of A in year t, his wage would be Ft+1(A+1) if he lived to be A+1 years old in year t+1, and would be Ft+2(A+2) if he lived to be A+2 years old in year t+2, etc. Ft+1(A+1) and Ft+2(A+2) are similar to Ft(A+1) and Ft(A+2), except that they have to

3.3.2 Quality of Life Costs Estimation method for calculating the value of loss in quality of life
In this study the costs related to losses in quality of life are measured based on opinions gathered from personal interviews conducted with those who are representatives of the people. These include legal experts in the public and private sectors, political representatives at the local government level (province, municipality, and tampon) and the national level (senators and members of the house of representatives). Some accident victims are interviewed both at hospitals and at their homes, covering both the disabled and the injured. Based on results from the interviews, it is clear that road accidents adversely affect the quality of life for both the victims and their families. Accident victims suffer from lack of employment and income, including inability to pursue happiness from sports, entertainment, and normal social activities. Their families also bear the burden of accidents when income losses by the victims and their careers must be compensated by borrowing to pay for hospital costs and family expenses. In many cases, the ability to invest and to finance children’s education is reduced. Most interviewees agree that the loss of quality of life depends on the severity of accidents and can be measured as a function of monetary losses e.g. lost output and medical expenses.
1 The rate of wage growth is set at 4%, 5% and 6% per year, and the discount rate is at 3% per year.
3 METHODOLOGY

Most interviewees put values on the loss of quality of life by relating it to two factors:
- the victims’ educational background, social status and income level before the accidents;
- the degree of impacts of the accidents on the victims’ physical and mental health.
It is generally accepted that any absolute numbers cannot be assigned to losses in quality of life, because the values tend to vary from case to case, depending much on the victims’ characteristics and circumstances. Therefore, this study has estimated losses in quality of life by setting them as percentages of lost output, long term care costs, and medical expenses, as shown in Equation 9.
Quality of Life Costs = (Victims’ Lost of Output + Carers’ Lost of Output +
medical expenses) x percentage of monetary loss (9)
Data and source for calculating the value of loss in quality of life For calculating the value of loss in quality of life as shown in Equation 9, we use the value of estimates lost of output in average case (assuming the average income growth of 6% and the discount rate of 6%) and the long-term medical and rehabilitation cost. The result of interviews on quality of life costs in Lampang province, Nakhonsawan province, Khon kaen province, Songkhla province, and Bangkok are shown in detail in Table 3.9 Table 3.9 : Results of Interviews on Quality of Life Costs

STEP 3: Determination of Unit Cost This involves compiling all costs incurred in treating crash-injured patients at Case Study Province Central Hospital based on records for the year 2004. Treatment expenditure involves the Direct and Indirect Costs sustained by two categories of care providers as follows: Direct Cost is sustained by the following departments: on-the-spot medic team, ER, Radiology, OR, ICU, In-Patient Unit. Indirect Cost occurs only at the Office of the Secretariat for Accident Prevention. SCOPE OF STUDY Investigation was conducted at the Case Study Province Central Hospital which is a tertiary-level hospital and confined to only those units where accident-related data were available. Data relating to treatment costs were collected from all departments including ER, IPD, OR, LAB, X-ray, ICU, Pharmacy, Physiotherapy, Orthotics. Only costs incurred by the patient’s first visit were collected; those incurred in subsequent visits or treatments were not considered due to limitations relating to data categorization and verification. DEFINITIONS COST — Resources expended on providing available services for patients injured in traffic accidents. Cost components include depreciation, labour charges and material outlay. DEPRECIATION — Amortization of the Capital Cost (CC – which includes assets such as office and medical equipment, buildings) over the number of years defined as the write-off period of such assets. LABOUR (LC) — This includes wages, overtime pay, shift pay, childcare allowance, travel allowance, medical allowance and welfare monies. MATERIALS (MC) — Consumable and permanent supplies for offices, lab use, medical use; and cost of repairs under 5,000 baht (excluding repair or upgrade on a building). MEDICAL CARE COST (MCC) — Cost of treatment administered to a patient. MCC in this study largely comprises Direct Costs. TOTAL MEDICAL COST FOR CASE STUDY PROVINCE CENTRAL HOSPITAL — Summation of all costs sustained at all hospitals large or small in Case Study Province relating to the treatment of crash-related injuries, and all expenses incurred at the Pre-Hospital stage, such as costs of local rescue teams, hospital emergency medics, accident response and forensic unit, and in-hospital costs such as ICU, IPD, OR and Rehabilitation. IDC = Indirect Cost – Comprising the costs of operating the Office of the Secretariat for Accident Prevention, an agency tasked with providing support for accident response services and academic developments in this field. Full/Total Cost: Full Cost = LC + MC + CC (Not shown in table)

TCT&I – Apportioning of the costs. = Full Cost (LC + MC + CC) divided by the number of accident-injured patients treated in Case Study Province Central Hospital. UCT &I – Unit Cost of treatment administered to accident-injured patients. The value is calculated by first apportioning the Total Cost according to the ratio of crash-related patients; then averaging the result to obtain the unit cost. From the data thus collected, the Unit Cost was calculated, as shown in Fig 3.3:- Pre hospital care Hospital care 18,215 Rehabilitation

3.3.4 Long Term Care Costs Calculation Method For disabilities caused by road accidents, the costs of long-term care are divided into two parts:
• The cost in terms of lost output by those relatives and friends who spend time taking care of the disabled, both working and non-working;
• The long-term medical and rehabilitation cost. Since the first part has already been explained in the “lost output” section, this section will deal only with long-term medical and rehabilitation cost, which is incurred from the year of the accident through to the year of death. It is assumed that the average medical cost in real terms is the same for each year. However, the nominal cost will be adjusted by 3.5% annually, based on the average annual increase in expenses on personal medical care found in the consumer price index survey between 1990 and 2005. According to our medical team, the life expectancy of the accident-related disabled is on the average 10 years shorter than normal. Therefore, the life expectancy for the disabled in this study is 58 years for males and 62 years for females, compared with 68 and 72 for normal persons. With the discount rate of 6%, the formula for the long-term medical cost calculation of each age group is:

where AL is the long-term medical cost of a person at the age of A
M is the average annual medical cost for one disabled person in 2004∗ g is the annual increase rate of the medical cost, set at 3.5%
r is the discount rate, set at 6% T is the difference between the life expectancy and the age during the
accident ∗ The medical cost is estimated from the actual medical cost of accident victims.

For instance, for a male who suffered from a road accident and became disabled in 2004 at the age of 40, we can assume that his remaining life is 18 years (the difference between 58 and 40), and his long-term medical cost is calculated as follows:

For a female who was disabled by a road accident in 2004 at the age of 40, having her remaining life of 22 years (the difference between 62 and 40), her long-term medical cost can be calculated as follows:

However, there is one case where a male accident victim in 2004 is in the age group of 60 – 64, thus exceeding the average life expectancy of 58. This one exceptional case represents only 0.86% of the total number of disabled victims, and therefore we assume his medical cost in 2004 to be his long-term medical cost.

3.3.2 Non-Vehicular Damage Cost 3.3.3.1 Number of Non-Vehicle Damaged Property Similarly, police records obtained from the logbook were used to estimate the average number of each type of road furniture damaged for each crash case. The average numbers of road furniture damaged per crash are shown in Table 3.15. Table 3.15 : Average Number of Road Furniture Damaged in a Crash
Source: Compiled by the Consultant 3.3.3.2 Non Vehicle Damage Cost The cost of public roadside property or furniture damages are obtained from the traffic accidents on national highways database file which is based on the study year 2004 prepared by the Department of Highways. In using with this database file, firstly, the accident records for Bangkok were extracted. then, the average costs of road furniture per crash determined. However, by considering only the accident cases in Bangkok, the sample size for each type of furniture damaged classified into crash severity was too small give a statistic ally significant value of costs. For this reason, the Consultant estimated average costs property of non-vehicle damage per crash categorized by each type of road furniture from the whole country records, the end results are shown in Table 3.16.

3.4 General Crash Costs This category of costs comprises expenses incurred by a crash wherein authorities or persons concerned with the management of the incident are required to act or to provide service. It includes administration costs incurred to insurance companies, police, the judicial system and expenses for the emergency rescue team. 3.4.1 Insurance Administration Cost The information on the amount of staff work are collected from insurance companies in the pilot provinces through interviews and statistical data. The insurance administration costs are mainly classified into three categories such as labor cost, material cost, and capital cost. The details in each category can be described as follows: Labor Cost The labor costs include all staff time in man-month unit indicating the amount of average salary per staff per month. This study only focuses on the insurance staff (i.e. surveyors, estimators, and administrative staff) who are directly involved in road accident claim documentation. Material Cost The average material costs per claim consist of fuel expenditure for transportation, maintenance cost of vehicle, office materials, photographs, telephone and mobile bills, and utility payment including water and electricity. Capital Cost The capital costs include the rental fee of office building, durable furniture, vehicles used in road accident claim management. The average cost of insurance administration across the five pilot provinces is shown in Table 3.18. Table 3.18: Average Insurance Administration Cost per Claim

3.4.2 Police Administration Cost The information on the amount of police works are obtained from the interview survey and annual records obtained from the police station in the pilot provinces. Given the ease of accessibility to the data and good cooperation, the Muang Police Station was selected as a model station for this study. The police administration costs in this study are classified into three main categories: labor cost, material cost, and capital cost. The details in each group can be described as follows: Labor Cost Generally, the main police officers involved with road crash cases are traffic police, inquiry personnel, and clerk who start their formal work-procedures after getting the information of crashes from the communication unit. Therefore, to identify average amount of staff-service time of these officers, the information on the amount of staff work done by each group of the police together with average wages are gathered from existing information and interview survey. Material Cost The material cost includes fuel expenditure used in inspecting and investigating the accident scene, maintenance cost for the vehicles, office materials used in accident cases, photographs of accident, communication expenditures, water and electricity bills are also covered in this study. Capital Cost The capital costs covers office building, durable furniture, vehicles used to deal with road traffic accidents are also included in this study. Cost of police administration in the five pilot provinces were found to differ significantly among the areas. Therefore a fixed rate is assumed for this cost for the whole country based on either a reported or unreported crash incident. The rates are shown in Table 3.19.

3.4.3 Judicial Administration Cost In general, two judicial court offices deal with the road traffic accident cases; they are attorney court and judicial court offices. Therefore, the expenditures of these two courts are similarly classified into three categories thus: labor cost, material cost, and capital cost. The details in each category can be described as follows: Labor Cost The judicial system staff consists of public attorney, lawyer, judge, and administration staff from these two courts. The labor cost data are collected both from the annual reports published by the office of the Attorney General of Region and the Office of the Chief Judge of Region as well as the interview survey. Material Cost Due to the limitations in gathering directly the material cost information from each court in the pilot provinces, the Consultant resorted to collect the material costs of the judicial system from the annual reports. Capital Cost This study focuses mainly on the capital cost of the judge office building which is the office of criminal law suit including road accident cases. This cost component includes the capital budget which is annually invested and spent for dealing with accident cases. The average cost of judicial administration per crash incident, taken from costs across the five pilot provinces, is shown in Table 3.20. Table 3.20: Average Judicial Administration Cost

3.4.4 Emergency Rescue Service Cost Due to the limitations in gathering the ERS cost data, the Consultant only collected the expenses of supporting road traffic accident rescues from two well-known foundations in the pilot province. The ERS costs are also similarly classified into three categories, labor cost, material cost, and capital cost. The details in each category can be described as follows: Labor Cost The labor costs cover the cost of communication staff receiving the call, wages of rescue driver, trained rescue staff, and administration staff directly dealing with the accidents. Material Cost These costs are fuel expenditure for transportation, maintenance cost of vehicles, office materials, communication expenditures, utility bills including water and electricity. Capital Cost The capital costs comprise office building, durable furniture; vehicles used in the rescue are also included in this study. From the determination of ERS cost in five pilot provinces, the average ERS cost per case can be summarized in Table 3.21. Table 3.21 : Average ERS Cost per Case

3.4.5 Travel Time Delay In order to perform an analysis of travel delay cost in the Bangkok Metropolitan Region, the data for the related parameters, namely travel time loss, traffic flow, level of blockage, occupancy rate, and average wage rate were collected. The following paragraphs describe these parameters and their determined values. Travel Time Loss The travel time loss is the combination of emergency service response time and clearance time after the arrival of emergency service team. The emergency service response time database was obtained from the Narinthorn Center. The average emergency service response time was determined to be 14 minutes. The clearance time after the arrival of emergency service team was collected by interviewing policemen responsible for accident investigations. Clearance time is related to accident severity. The following table shows the emergency service response time, clearance time and travel time loss categorized by accident severity. Table 3.22: The Travel Time Loss for the Bangkok Metropolitan Region Categorized by Accident Severity

Source : Narinthorn Center and interview with policemen responsible for accident investigations Table 3.22 indicates that travel time loss is the highest for fatal crash, followed by serious crash, slight crash and property damage only (PDO). The component of travel time loss, clearance time, is also related to accident severity. However, the emergency service response time is independent of accident severity. Traffic Flow Table 3.23 summarizes the traffic volume for passenger car, pick-up, motorcycle, truck and bus. These data were obtained from an Intermodal Services Integration for the Improvement of Mobility, Accessibility, Sustainability and Livelihood for Bangkok Metropolitan Region and Surrounding Area (IMAC) project.

4 RESULTS OF THE STUDY
4.1 Introduction Khon Kaen was selected as one area for a pilot study as the province has a somewhat systematic database of accidents. The province has established an accident response centre, which has been operating since 1996, at the Khon Kaen Central Hospital (KKH). This centre has compiled an IS database which is well recognized. A number of previous studies by established agencies and institutions have also designated Khon Kaen as their target area for the investigation of accident-related issues. The Consultant also conducted studies in four other provinces in order to verify the applicability of the method to all of the provinces across Thailand. The four other provinces consist of Lampang, Nakhonsawan, Songkhla, and Bangkok. 4.2 Preliminary Accident Costing Model Cost incurred by a traffic accident can be determined with the Human Capital Approach using the equation below: Total Traffic Accident Cost = A+B+C The three categories of cost are laid out below: 1. Human Cost Category, (A) = A1+A2+A3+A4 2. Property Damage Cost Category, (B) = B1+B2 3. General Crash Cost Category,(C) = C1+C2+C3+C4+C5 A description of these cost elements is given in Table 4.1

5 TRAFFIC ACCIDENT COSTS IN THAILAND
5.1 Introduction Investigation into the range of costs incurred by road crashes in the five pilot provinces, as discussed in Chapter 3, served as the basis for estimating the losses associated with road accidents in Thailand. The five provinces where studies were conducted are representative of 76 provinces As mentioned in Chapter 2, the cost elements of a road accident are classified into three categories: Human Costs, Property Damage Costs, and General Crash Costs. In order to calculate the total losses arising from traffic accidents, two sets of data, which are 1) the number of casualties and crashes and 2) the unit cost data, must first be compiled. The compilation of such data is described in the following topics. 5.2 Number of Casualties and Crashes 5.2.1 Number of Casualties In this study, crash-related casualties are classified into four groups according to the severity of injury, namely fatal, physical disabling, seriously injured, and slightly injured. Raw data of crash casualties were obtained from the Annual Epidemiological Surveillance Report 2004 published by the Bureau of Epidemiology, Ministry of Public Health. Since the data of crash injury obtained from the said report were not classified according to the severity of injury, the consultant therefore split the crash injury data into three groups, i.e. physically disabling, seriously injured, and slightly injured, according to the percentages obtained from studies conducted in the five provinces. Table 5.1 shows the numbers of crash casualty in degrees of severity derived by this method.

Under reported Data In addition, casualty data obtained from the Royal Thai Police, the Bureau of Epidemiology and other data collected by the consultant were grouped into two main categories: Death (fatal) and Injury (non-fatal). The numbers were compared and their relative magnitudes calculated. The fatality and injury ratios thus obtained will provide a basis for normalising accident casualty figures reported by different sources. Breakdown of road accident casualty data for Bangkok and four other target provinces are shown in tables to 5.2 and 5.3 below. Table 5.2: Casualty Ratios for Bangkok based on data from 3 sources
Fatalities Injuries Source
Number Percentage Number Ratio
Royal Thai Police 815 1.09 23,307 0.39
Bureau of Epidemiology 134 0.18 24,796 0.42
The Consultant 746 1.00 59,272 1.00
In Table 5.2, the number of deaths reported by the three sources are in the ratio of 1.09: 0.18: 1.00. It can be seen that the figure reported by the Royal Thai Police and that by the consultant are quite comparable; the slight difference between the two is of no significance. In contrast, the fatality figure reported by The Bureau of Epidemiology is way below that of the other two sources. This was because data from the Bureau of Epidemiology were limited to those collected from the hospitals attached to the Public Health Ministry. Therefore, for the purpose of normalising the Bangkok fatality rate, data from the Royal Thai Police, or the average of the rates obtained from the Royal Thai police and the consultant, may be used as a base figure. For the “Injury” category, data from the three sources show marked differences, i.e. 0.39: 0.42: 1.00. Figures from the Royal Police and the Bureau of Epidemiology are less than half the number obtained by consultant. This was because a large number of minor injuries, as normally occurred in accident cases in Bangkok, were not reported to the authorities, thereby resulting in the lower numbers. In contrast, statistics collected by the consultant were obtained from all types of hospital including those not attached to Public Health Ministry as well as private hospitals where a significant number of small injuries are treated. Therefore, if data from the above two sources are to be used, they should be normalised against that of the consultant’s in order to reflect the actual situation. Data collected from the other four provinces, as shown in Table 5.3, are regarded as representative of the true situation outside of Bangkok. Table 4 .3 shows a low fatality rate reported by the Royal Thai Police. Similarly, fatal cases reported by the Bureau of Epidemiology are also on the low side. Fatality rates obtained by consultant, by contrast,
5 TRAFFIC ACCIDENT COST IN THAILAND 5 - 5
The Study of Traffic Accident Cost in Thailand Final Report
are higher than the numbers obtained from the other two sources by some 35%. Again, the large difference was due to the consultant’s more comprehensive collection method: data were collected from all types of hospital covering hospitals under the Public Health Ministry, private hospitals and university hospitals in Khon Khaen and Songkhla. “Injury” figures reported by the Royal Thai Police is on the low side when compared against data collected by the consultant. This was because only the injury pertaining to actionable cases and logged in police journals was reported. Injury rates reported by the Bureau of Epidemiology is likewise lower by some 30%, being limited to cases treated by Ministry-affiliated hospitals, whereas consultant’s number was the result of a much wider extent of collection including data from private hospitals and university hospitals in Khon Khaen and Songkhla.

5.2.2 Number of Crashes Data collected from police stations in the five pilot provinces showed no significant difference in the casualties-per-crash averages (by degree of severity) for Lampang, Nakhonsawan, Khonkaen, and Songkhla while a marked difference was observed in the same figures for Bangkok. Therefore, the average casualties-per-crash are finally grouped in two i.e. averages for Bangkok as one, and Other Provinces as another group. The latter group comprises averages of figures derived for the four provinces. Results of such grouping are shown in Table 5.4 and Table 5.5.

5.3 Unit Cost 5.3.1 Human Costs Category 5.3.1.1 Loss of Productivity Cost The unit costs of production loss per casualty were determined for the crashes based on gender and age groups using the information from IS data of hospitals in the five pilot provinces. In addition, the calculation took into account the local wage function which is in dependent on local economic factors as explained in Chapter 2. Another component was the weighted average of the wage scales. All these components were considered in determining the average productivity loss for each province. The final productivity losses incurred according to degrees of accident severity are summarized in Tables 5.18 below. It should be noted that in estimating productivity losses due to serious and slight injuries, only one medical-care provider, such as a nurse, is factored into the estimation. However, for the case of physically disabling injury, the productivity loss of such a care provider is added to the long term cost of care.

5.3.1.2 Quality of Life Cost In order to determine this aspect of the costs, the Consultant conducted a number of interviews with citizens, experts, and accident victims in the pilot provinces to find out the extent of losses in the quality of life caused by road accidents. Results of the interviews are shown in Table 5.19. Productivity losses of the accident victim and the care provider together with hospital-care cost are summed up, and the sum then multiplied by the figures in Table 5.19. The results thus obtained show the monetary value of quality of life losses (fatality, disability serious and slight = 125, 150, 75 and 25 respectively). These are shown in Table 5.20.

5.3.1.3 Medical Care Cost Since the cost of medical care was found to be fairly uniform across all of the pilot provinces, it is assumed that such a cost pattern would be typical across Thailand. The Consultant therefore determined the unit cost by averaging all the prices obtained from the five provinces in order to arrive at a cost that is applicable for the whole country. The average cost of treating crash patients according to degrees of injury severity is summarized in Table 5.21. Table 5.21 : Average Crash Patients Treatment Cost by Degree of Severity

7.3 Application of Crash Cost Estimates This section gives an example for application of crash cost estimates. Statistics of Large-Bus Crashes -- Data from Highways Department Data of crashes on national highways obtained from the DOH’s nation-wide reporting system between 2002 and 2006 are shown in Table 7.7 below. For 2006, there were altogether 360 crashes involving 370 large inter-city buses resulting in 153 fatalities and 1,042 injuries (252 of which were serious and 790 slight injuries). Table 7.7: Number of Large-Bus Crashes on National Highways, with Associated Fatalities and Injuries, from 2002 to 2006 (5 years)

Source: Bureau of Traffic Safety, Department of Highways, 2007 Figures in Table 7.7 indicate that for every crash, the number of fatalities are 0.42; disabilities 0.03 serious injuries 0.79 and slight injuries 2.76. The cost incurred in each crash is computed thus: = 0.42*4,658,004 + 0.03*5,404,175 + 0.79*128,836 + 2.76*30,461 which amounts to 2,304,340 or approximately 2.3 million baht per crash. The total cost of large-bus crashes on national highways for the 5 years period 2002-2006 is equal to 2758*2.3 or 6,343.4 million Baht.

7.4 Problems Encountered in Data Collection Data were collected in Khon Kaen, Lampang, Nakhonsawan, Songkhla, and Bangkok from public and private-sector agencies involved in crash-related activity. Interviews were conducted with a number of people involved including government authorities, experts as well as the families and friends of accident victims. Losses ascribed to traffic accidents were then assessed and categorized. This results in three categories of losses; the first category is the human costs, the second, the properties damaged, and the third is general losses associated with traffic crashes. In general, the main difficulty in such an undertaking was shortage of well-maintained data. The data kept by most of the government and private agencies concerned were either fragmented or un-searchable, or lacking proper cross-referencing among the various care providers, thus any effort at cross checking or verification was severely hampered.
1. Crash injury data of some of the care providers were not systematically maintained, thus could not be readily employed. The Consultant had to resort to the IS database of the Khon Kaen Central Hospital, Lampang Central Hospital, Nakhonsawanpracharak Hospital, Hatyai and records from the Report on Survey of Human Disability and Incapacity 2002 of the National Statistical Office for determining percentages in each data category such as gender, age and number of crash-induced disabilities.
2. Data of crash vehicle repair costs kept by insurance companies were largely inaccessible. Those that were available were limited to broad, overall figures; none were systematically maintained data. To remedy this lack, the Consultant obtained additional data from repair garages in order to better gauge the costs associated with crash-damaged vehicles.
3. Data relating to losses of properties other than vehicles were requested from Department of Highways and road authorities. For some agencies, such data had not been maintained properly, thereby hampering data checking. Much of these data could not be employed for this investigation.

APPENDIX D
The Study of Traffic Accident Cost in Thailand Final Report
1
Data for calculating the value of lost output
Estimation Method
In estimating the value of lost output due to road accidents in Khon Kaen, we start with the estimation of a labor hour function and a wage function in which variables on worker characteristics (age, sex, education, geographical location, and workplace) are incorporated. Estimates from these two functions are then used in calculating an individual’s foregone income, as detailed in section 3.1.1. The formulae for calculating lost output from different types of accident impacts are summarized in Table 1.
APPENDIX D
The Study of Traffic Accident Cost in Thailand Final Report
2
Table 1 : Summary of formulae for calculating lost output Type of Output Loss Calculating Formula
1. Lost output through death Number of fatalities × Foregone Income 2. Lost output by the disabled who cannot work
Number of non-working disabilities × Foregone Income
3. Lost output by the disabled who can work with 30% income
Number of working disabilities × Foregone Income × 30%
4. Lost output through serious injury (in-patients)
Number of the seriously injured × Number of lost working days × Daily wage
5. Lost output through slight injury (out-patients)
Number of the slightly injured × Number of lost working days × Daily wage
6. Lost output by carers: 1) Caring for the non-working
disabled 2) Caring for the working
disabled 3) Caring for the injured
32.5% × Lost output by the disabled who cannot work 4.2% × Lost output by the disabled who can work Lost output through serious injury + Lost output through slight injury
Notes : 1) Accident victims who are disabled and can still work are assumed to reduce their working efficiency down to 30% of the previous level, according to Worawate (2004)
2) The percentages of 32.5% and 4.2% used in cases of caring for the disabled are derived from Survey on Disabilities and Handicap in 2002 by the National Statistical Office.

Data and Sources of Data
In estimating the value of lost output of road accident victims, we use the following data.
1. Data for Estimating Labor Hour and Wage Functions Data on worker characteristics (age, sex, education, geographical location, and workplace) and wages are necessary for estimating a labor hour function, a wage function and foregone income, as explained in detail in section 3.1.1. These data are obtained from a quarterly survey on working conditions for the third quarter of 2004. (See details in Appendix D.) 2. Data for Estimating Lost Output These data consist of:
1) Number of accident fatalities classified by sex and age from the IS database of the Khon Kaen Central Hospital (See Table 1). In 2004 the number of fatalities in road crashes in Khon Kaen province is 639, and we use the IS database to classified by sex and age. The results are shown in Table 2.

4) The length of hospitalization period includes the number of days of medical treatment in hospital and the number of recuperating days at home. Wannarha Sumirattana (1996) finds that the number of recuperating days is roughly equal to the number of days of medical treatment in hospital. This study adopts this finding and therefore the number of days of hospitalization for serious injuries is twice the number of days of medical treatment in hospital. Details are displayed in Table 10.

In slight injury cases, the number of days of hospitalization is 2 (one day is for medical treatment and another day for recuperation) in both sexes and every age group.
5) Average daily wages and annual incomes for different age groups are calculated from
a labor hour function and a wage function which are estimated from the data obtained from a quarterly survey on working conditions for the third quarter of 2004. (See details in Appendix D.) We use monthly wages for different age groups to calculate daily wages by dividing the monthly wage by 21.75 (One month is assumed to be equivalent to 4.35 weeks and one week is assumed to be equivalent to 5 days, as proposed in Nipon Puapongsakorn and Surachai Keetatrakoon (1997)).

Data for calculating the value of loss in quality of life In this study the costs related to losses in quality of life are measured based on opinions gathered from personal interviews conducted with those who are supposed to be representatives of the people in Khon Kaen province. These include legal experts in the public and private sectors, political representatives at the local government level (province, municipality, and tambon) and the national level (senators and members of the house of representatives). Some accident victims are interviewed both at hospitals and at their homes, covering both the disabled and the injured. The questions asked in these interviews are shown in Appendix A. Based on results from the interviews of 13 legal experts and political representatives and 21 accident victims of which 11 cases in hospital and 10 cases at their homes in Khon Kaen, it is clear that road accidents adversely affect the quality of life for both the victims and their families. Accident victims suffer from lack of employment and income, including inability to pursue happiness from sports, entertainment, and normal social activities. Their families also bear the burden of accidents when income losses by the victims and their carers must be compensated by borrowing to pay for hospital costs and family expenses. In many cases, the ability to invest and to finance children’s education is reduced. However the number of political interviewees in Khon Kaen province is too small. Therefore, we added more representatives interviewed in Songkhla to our samples. Most interviewees agree that the loss in quality of life depends on the severity of accidents and can be measured as a function of monetary losses e.g. lost output and medical expenses. A group of accident victims were also interviewed in Khon Kaen and Songkhla. These include 11 persons who were being hospitalized, 18 disabled persons, and 4 injured persons who have recovered. The interviews of these victims confirm the conclusion from expert

opinions on the suffering, grief and pain experienced by the victims and their family members. It is interesting to note that while they could not exactly specify the values of these losses in their quality of life, most thought that the losses would be quite high in monetary terms. Most interviewees put values on the loss of lower quality of life by relating it to two factors: − the victims’ educational background, social status and income level before the
accidents; − the degree of impacts of the accidents on the victims’ physical and mental health.
It is generally accepted that any absolute numbers cannot be assigned to losses in quality of life, because the values tend to vary from case to case, depending much on the victims’ characteristics and circumstances. Therefore, this study will estimate losses in quality of life by setting them as percentages of lost output, long term care costs , and medical expenses. The values of these percentages are shown in detail in Table 1.

The average wage rate for passenger
The average wage rate for passenger who traveled by passenger car and pick-
up, motorcycle, truck, and bus can be computed by assuming the occupation and level of education for each passenger. There are 4 groups of passenger as shown in the following paragraphs.
Group 1 Passenger car and pick-up
Occupation LEGISLAT = legislators, high-ranking officials, and managers PROFESS = professionals
Level of education UNIACAD = academic university education UNIVOC = vocational university education UNIEDU = teachers training university education
Group 2 Motorcycle
Occupation TECHNIC = technicians CLERK = clerks Level of education DIPLACAD = academic diploma education DIPLVOC = vocational diploma education DIPLEDU = teachers training diploma education
Group 3 Truck
Occupation SERVICE = waiters and sale persons SKILL = skilled worker in agriculture CRAFT = craftsman
APPENDIX D 2
The Study of Traffic Accident Cost in Thailand Final Report
Level of education UPSECGE = upper secondary school education UPSECVOC = vocational secondary school education UPSECEDU = teachers training school education
Group 4 Bus
Occupation PLANT = plant operators MINING = mining workers Level of education UNDERELE = education below primary school ELEMENT = primary school education LOWSEC = lower secondary school education
In order to determine the wage function, the variable of occupation and level of
education belonging to each group of passenger are coded as “1”, and otherwise, coded as “0”.
