August 2011 briefing notes crash analysis Waikato Region 2006 to 2010
Waikato Region This report provides a snapshot of the Waikato road safety region’s traffic crash data for the period 2006 to 2010. This is the 12th year we have produced a set of briefing notes reporting on traffic crash data and addressing road safety issues across all territorial local authorities.
Safer Journeys (NZ’s Road Safety Strategy 2020) is built upon a safe system approach to road safety, where the emphasis is on reducing the effects of crashes as much as the numbers, and most importantly on reducing fatal and serious casualties on our roads. A crash is a single event that may involve multiple parties, many contributing factors and various casualties.
We have focused on the areas of high, medium and emerging concern, set out in Safer Journeys, that are a strategic priority when compared nationally. Each area of concern is assessed locally and regionally by calculating the individual road user’s risk of a fatal or a serious injury.
We present 2010 overviews of the region and its local bodies based upon reported crash data, and the latest trends and crash characteristics for the 2006–2010 period. The identified regional issues are discussed in more detail. The information in this report covers both local roads (council owned roads) and state highways. Injury crash data is used throughout the report in charts, tables and maps, unless otherwise stated.
Note that the road safety region consists of the territorial local authorities that appear on page 8 and somewhat differs from the local government region.

Safer Journeys, New Zealand’s Road Safety Strategy 2010–2020, envisions a safe road system increasingly free of death and serious injury and introduces the Safe System approach to New Zealand. This approach represents a fundamental shift in the way we think about road safety. A Safe System approach is about acknowledging that: • Human beings make mistakes and crashes are inevitable • The human body has a limited ability to withstand crash forces • System designers and users must all share responsibility for managing crash forces to a level that does
not result in death or serious injury • It will take a whole-of-system approach to implement the Safe System approach in New Zealand
Safe System approach

Taking a safe system approach - a case study The following case study is an example of what can go wrong while driving a vehicle on a public road. The parents of the crash victims referred to in the case study have expressed the wish that their tragic story will contribute to safer journeys for all New Zealanders in the future.
It was late afternoon one day In January 2007 when two teenage sisters aged 18 and 15 were tragically killed as a result of a crash. They were on an over bridge when their car slid sideways, crossed the centreline and hit an oncoming truck. They were killed instantly.
The coroner’s report identified a number of factors which contributed to the crash. These factors included the tyres fitted to the vehicle, and also the possibility that the driver was texting while driving and may have been distracted.
In a safe road system we are encouraged to look at all aspects around crashes on the roads as we work to have a road network increasingly free from death and serious injury.
This incident demonstrates the many factors typically involved in a crash. To avoid similar fatalities we need to look beyond driver blame and work on strengthening all parts of the system: the roads and roadsides, the speed, the vehicle and the road use. The response to a problem may lie in more than one of these four cornerstones of a safe road system. For instance, in future, better management of both speed and loss of control may lie in vehicle technology.
Using the principles of a Safe System approach in this case, the following has been observed:
• Safe roads and roadsides: This section of State Highway 1 has a 100km/h speed limit and is rated a ‘two star’ road using the KiwiRAP* system for rating roads. The bridge where the crash occurred had a moderate right hand curve and a speed advisory of 85km/h. Records indicate that there had been five injury crashes reported in the immediate vicinity of the bridge. These included four lost control crashes, one of which resulted in a head-on crash.
* KiwiRAP rates roads from one to five stars according to their safety features.
• Safe vehicles: The vehicle driven by the sisters was a 1998 Japanese imported Toyota Trueno, which was unrated in the ANCAP* system. The vehicle had a current warrant of fitness at the time of the crash, but it was found that the tyres were not matched and the rear ones were both low in tread, and designed for cold/snow conditions. If the vehicle involved in this crash had been a five star ANCAP rated vehicle, the chances of fatality would have been reduced. Evidence suggests that this vehicle had lost control on more than one occasion previously due to driver input and had previously been involved in a crash and subsequently repaired.
* The Australasian New Car Assessment Programme (ANCAP) tests the protection provided to front seat occupants in serious head-on and side-impact crashes. These ratings allows comparison of the crash protection offered in a serious crash by different vehicles of similar weight.
• Safe road use: The driver of the car was an 18 year old who held a restricted drivers licence and had been driving for about two years. Evidence indicates that she may have been texting while driving and may have been distracted. In 2010 the law changed making cell phone use while driving illegal.
• Safe speeds: Since the crash the advisory speed has been reduced to 75km/h, and the sign is highlighted by a large white background. The Police investigation established that this vehicle was likely to have lost control due to fast steering input and that excessive speed could not be supported as a cause of the crash.
While this tragic crash is still fresh in the memory of these teenagers’ loved ones, the lessons we can learn from a Safe System approach are of immense value. Road controlling authorities are encouraged to apply the Safe System approach in all their planning. Together we can achieve safer journeys for all New Zealanders.

Regional variance of individual risk (2006-2010 fatal and serious casualties)
These two charts show the variance of individual risk to specific road users across the road safety regions. The chart above shows young drivers of light vehicles, that is those aged 15-24 years, compared with older road users—persons aged over 74 years. The chart below shows and compares the individual risk to vulnerable road users, these are motorcyclists, cyclists and pedestrians. This measure of risk has been used in this series of reports to select specific issues to be discussed at a regional level.

Total 143 773 3,704 4,620
Casualties by urban/rural 2006-2010
The most common crash movement types in fatal and serious crashes on local roads were ‘loss of control on a right hand bend’ (150 crashes), ‘loss of control on a left hand bend’ (107 crashes) and ‘loss of control on a straight road/off road to the left’ (48 crashes). The chart below shows the types of crashes reported by the New Zealand Police. Note that although CAS is able to identify 87 different crash movements. It can also group them into similar crash types.

Weather 6 7 There are almost 400 contributory crash factors that can be used in CAS to describe crash causes. However it needs to be noted that these ‘factors’ are not necessarily an ‘illegal’ act. For example if a pedestrian is ‘wearing dark clothing’ at night it may be recorded as a crash contributor, in the same way that ‘poor street lighting’ can be tagged as a contributor. As with the crash movements, CAS is also able to group these, as in the following table. Most crashes have more than one factor attributed to them and as a result the percentages below will not add to 100.
Further information about the 3,513 injury crashes on local roads 2006 to 2010:
• 26 percent on wet roads
• 36 percent at intersections
• 2204 roadside objects struck
• Most represented five year age group in at fault drivers, 15 to 19 years (22 percent of at fault drivers)
• 10 percent of crashes involved motorcycles
• Social cost of crashes $1245.3m

Regional speed related fatal and serious crashes
13 August 2011 briefing notes crash analysis Waikato Region 2006 to 2010
Nationally, speed is one of the major contributing factors to road crashes. Reducing speeds is an important road safety goal for Safer Journeys. Excessive speed increases the likelihood of a crash occurring by reducing the time available for drivers to respond to situations and it leads to more serious injuries. Between 2006 and 2010, 20 percent of injury crashes in the region involved travelling too fast for the conditions.
Speed
Further information about speed related injury crashes in Waikato Region 2006-2010:
Local roads • In 728 injury crashes there were 67 deaths, 211
serious injuries and 788 minor injuries
• Most common crash type ‘lost control at a bend’ (537 crashes)
• 34 percent wet road • 47 percent night time • 36 percent include alcohol as a factor • Worst three hour time period, 3pm to 6pm
State highways • In 572 injury crashes there were 64 deaths, 181
serious injuries and 639 minor injuries
• Most common crash type ‘lost control at a bend’ (438 crashes)
• 45 percent wet road • 42 percent night time • 23 percent include alcohol as a factor • Worst three hour time period, 3pm to 6pm
Speed related crashes in CAS are not crashes where the driver was exceeding the posted speed limit, (although that may also be the case), but are crashes where in the opinion of the reporting Police Officer the driver was travelling too fast for the prevailing conditions. Certainly getting the message through that the posted speed limit is a maximum, but not necessarily a safe speed for every bend, crest, dip or isolated development (or driver) is the key to lowering the crash rate. Local bodies and highway managers can do their part by making sure limits are reasonable, comply with the Speed Limits Rule and are adequately signposted. The Police can do their part by using CAS crash data to put special emphasis where there is demonstrated risk. In this way there is a better chance that drivers will accept that the enforcement is not simply ‘revenue gathering’.

Regional rural road fatal and serious crashes
15 August 2011 briefing notes crash analysis Waikato Region 2006 to 2010
High risk rural roads are a high priority for Safer Journeys and many of the issues for these roads are around the provision of a safe road environment. This includes appropriate geometric design, good delineation, adequate surface skid resistance and a roadside free of unforgiving hazards. Between 2006 and 2010 in Waikato Region there were 3,823 injury crashes on rural roads (that is roads with a speed limit of 80km/hr or more). This represents 71 percent of all fatal and serious crashes in the region.
Rural roads
Further information about injury rural road crashes in Waikato Region 2006-2010:
Local roads • In 1,496 crashes there were 104 deaths, 442
serious injuries and 1,537 minor injuries
• Most common crash type was ‘loss of control at a bend’ (857 crashes)
• 14 percent at intersections • 29 percent wet road • 36 percent night time • 1,323 roadside objects struck • 22 percent of crashes included a contributory road
related crash factor
• Most common at fault driver age group, 15 to 19 years (20 percent of at fault drivers)
State highways • In 2,327 crashes there were 212 deaths, 696 serious
injuries and 2,710 minor injuries
• Most common crash type ‘loss of control at a bend’ (1,152 crashes)
• 17 percent at intersections • 32 percent wet road • 1,893 roadside objects struck • 32 percent night time • 22 percent of crashes included a contributory road
related crash factor
• Most common at fault driver age group, 30 to 39 years (17 percent of at fault drivers)
Types of road factors in injury crashes
Road factor type Number of times reported
Slippery road* 671
Road surface in poor condition 173
Road obstructed 18
Visibility limited 68
Signs or signals (needed or faulty) 14
Markings (needed or faulty) 5
Street lighting 5
A significant problem on rural roads are roadside hazards which contribute to the overall crash outcome by increasing injury severity but can in themselves be a contributory factor in a crash. For example occupants in an errant vehicle striking a large tree close to the road edge are likely to sustain worse injuries than if the tree was not present. CAS records road conditions and road faults at the time of the crash if they are reported by the attending police officer and these are detailed below.
* note that NZTA does not assume that a road that is ‘wet’ is necessarily ‘slippery’. This factor is only added to CAS if the attending Police Officer specifically mentions a ‘slippery road’.

Regional fatigue related fatal and serious crashes
17 August 2011 briefing notes crash analysis Waikato Region 2006 to 2010
Reducing the impact of fatigue is an area of medium concern for Safer Journeys. It has long been recognised that fatigue is under-reported in New Zealand. In fact overseas research suggests that up to 25 percent of all fatal crashes could be fatigue related. Fatigue is a condition that is present long before a driver falls asleep. It has negative impacts on reaction time, the ability to concentrate, and a driver’s understanding of the prevailing road and traffic conditions. In Waikato Region there were 572 fatigue related injury crashes representing 9 percent of all crashes.
Fatigue

Thames-Coromandel District local roads Between 2006 and 2010 in Thames-Coromandel District there were 130 injury crashes on local roads. The table below shows the number of injuries resulting from these crashes by rural or urban areas. Rural is defined as an area with a speed limit of 80km/hr or more.

Casualties by urban / rural 2006 to 2010 Local roads
The most common crash movement types in injury crashes on local roads were ‘loss of control on a right hand bend’ (15 percent of crashes), ‘loss of control on a left hand bend’ (13 percent of crashes) and ‘crossing vehicles colliding at a right angle’ (11 percent of crashes). The chart below shows the types of injury crashes reported by the New Zealand Police. CAS is able to identify 87 different crash movements. It can also group them into similar crash types and these are shown in the chart below.
As with the crash movements, CAS is also able to group these, as in the following table. Most crashes have more than one factor attributed to them and as a result the percentages below will not add to 100.
There are almost 400 contributory crash factors that can be used in CAS to describe crash causes. However it needs to be noted that these ‘factors’ are not necessarily an ‘illegal’ act. For example if a pedestrian is ‘wearing dark clothing’ at night it may be recorded as a crash contributor, in the same way that ‘poor street lighting’ can be tagged.
Further information about the 130 injury crashes on local roads in Thames-Coromandel District 2006 to 2010:
• 22 percent on wet roads
• 35 percent at intersections
• 87 roadside objects struck
• Most represented five year age group in at fault drivers, 15 to 19 years
• 8 percent of crashes involved motorcycles
• Social cost of crashes $41.2m

The vehicles most commonly involved in fatal and serious crashes were cars (75 percent), trucks (24 percent), SUV’s (16 percent) and motorcycles (13 percent). The chart below shows the types of injury crashes reported by the New Zealand Police. CAS is able to identify 87 different crash movements. It can also group them into similar crash types and these are shown in the chart below.
As with the crash movements, CAS is also able to group these, as in the following table. Most crashes have more than one factor attributed to it and as a result the percentages below will not add to 100.
There are almost 400 contributory crash factors that can be used in CAS to describe crash causes. However it needs to be noted that these ‘factors’ are not necessarily an ‘illegal’ act. For example if a pedestrian is ‘wearing dark clothing’ at night it may be recorded as a crash contributor, in the same way that ‘poor street lighting’ can be tagged.

Casualties by urban / rural 2006 to 2010 Local roads
Males represented 69 percent of at fault drivers in injury crashes on local roads in the district. The types of vehicles that were most frequently involved in local road injury crashes were cars (62), vans or utes (13), SUV’s (13) and motorcycles (11). Thirty-four percent of local road injury crashes had an environmental factor. The chart below shows the types of injury crashes reported by the New Zealand Police. CAS is able to identify 87 different crash movements. It can also group them into similar crash types and these are shown in the chart below.
As with the crash movements, CAS is also able to group these, as in the following table. Most crashes have more than one factor attributed to it and as a result the percentages below will not add to 100.
There are almost 400 contributory crash factors that can be used in CAS to describe crash causes. However it needs to be noted that these ‘factors’ are not necessarily an ‘illegal’ act. For example if a pedestrian is ‘wearing dark clothing’ at night it may be recorded as a crash contributor, in the same way that ‘poor street lighting’ can be tagged.
Further information about the 87 injury crashes on local roads in Otorohanga District 2006 to 2010:
• 32 percent on wet roads
• 13 percent at intersections
• 90 roadside objects struck
• Most represented five year age group in at fault drivers, 15 to 19 years

Casualties by urban / rural 2006 to 2010 Local roads
The most common types of vehicles involved in fatal and serious crashes on local roads in the district were cars (59 percent), motorcycles (21 percent), SUV’s (20 percent) and vans or utes (17 percent). Fifty-six percent of fatal and serious crashes on local roads in the district were single party crashes. Males represented 81 percent of drivers at fault in fatal and serious crashes on local roads. The chart below shows the types of injury crashes reported by the New Zealand Police. CAS is able to identify 87 different crash movements. It can also group them into similar crash types and these are shown in the chart below.
As with the crash movements, CAS is also able to group these, as in the following table. Most crashes have more than one factor attributed to it and as a result the percentages below will not add to 100.
There are almost 400 contributory crash factors that can be used in CAS to describe crash causes. However it needs to be noted that these ‘factors’ are not necessarily an ‘illegal’ act. For example if a pedestrian is ‘wearing dark clothing’ at night it may be recorded as a crash contributor, in the same way that ‘poor street lighting’ can be tagged.

This report has been prepared by the Crash Analysis team at the NZ Transport Agency. The intent of this report is to highlight road safety issues and assist in identifying possible ways to reduce the number of road deaths and injuries. It has been prepared using data from the NZTA and Ministry of Transport’s Crash Analysis System (CAS) database. The Briefing Notes present information derived from pertinent statistics to be used for decision support. More detailed information may be obtained from either the local council (local roads), regional council or the NZ Transport Agency. The NZ Transport Agency encourages local bodies, regional councils and NZ Police to study the briefing notes reports. There will be road safety issues beyond those covered in this Road Safety Issues Report and we encourage our partners to use their access to the Crash Analysis System to identify and examine these further.
