EXECUTIVE SUMMARY
Both the rapid speed of change and the changes in society due to the information revolution in general, poses special challenges for forecasting the future of e-business and assessing its impacts. The traditional processes of collecting information over time, describing a base case and projecting of future trends, or assessing change scenarios, encounters problems in all stages.
These challenges apply to studies of impacts on the economy in general but are greater in studies of impacts in specific industries, such as transport. More detailed information is required and more detailed outputs are expected. Almost always such studies are looking for sufficiently detailed insights on future conditions to allow plans to be put in place. This requires predictions to be linked closely to time frames and specifics of localities.
Network data adds connectivity, type of link and link capacity information to geographic mapping data of roads and railway lines. The road authorities in each state hold complete network data for their states often augmented by road condition data.
Linking capacity and linking condition may be particularly relevant to assessment of the future ability of the road or rail system to accommodate future e-commerce. This might be applied to consideration of capacity of local roads for urban freight in cities or to measure highway or railway capacity for inter-urban freight movements.
In common with workplace and industrial locations, commodity flows are likely to change with a rise in e-commerce. It is possible these changes may occur within a five-year framework.
Examples of available data for tracking activities, which may change rapidly within a five- year period, have been divided for convenience into those relating to personal activity and those relating to business activity. Both types of data are discussed in section three of this Working Paper.
Vehicle registration and licensing databases show locations and numbers of registered vehicle types by location. While they provide information on the passenger fleet they are of particular value in the e-business context in tracking changes in numbers and types of commercial vehicle and also in holders of commercial vehicle licences. Individual states and territories hold these databases. In addition, the ABS also collects the data to report on an Australia wide basis.
Consideration of changes in the urban freight task is particularly important in estimating the impacts of e-business on the road system and vice versa. For example, will e-commerce add to congestion and equally what will be the impacts of congestion on e-commerce? Until recently transport planners concentrated on commuter travel. Estimates of future demands were modelled on passenger transport needs and the extra demands of freight were simply ‘loaded onto the network’.

1 INTRODUCTION
1.1 Tracking Change
E-Business encompassing e-commerce between businesses [B2B] or from business to consumer
[B2C] and the use of electronic technology within business is already changing the way
business is conducted internationally, nationally, within states and at the local area level.
Moreover, the pace of change is increasing. The planning for transport infrastructure and
services needs to accommodate such change. A study of e-Business and the Australian
Transport System by Queensland University of Technology [QUT] and CSIRO, with the
support of Queensland Department of Public Works, for the National Transport Secretariat, is to
investigate:
• how will the transport task change;
• what will be affected; and
• how can the transport system respond?
To effectively answer any of these questions, we need processes for assessing the current state
of play, tracking changes and predicting future trends. To answer the third question effectively
the relative importance of changes and associated responses need to be addressed. All these
processes need appropriate data. This Working Paper is the fifth in a series reporting this study
and addresses issues of data and associated sources, which may be applied in ongoing
assessment of e-business impacts. We emphasise that time and resources were not available for
a complete study of all possible data sources.
The rapid rate of change makes even the task of assessing the present difficult. As can be seen
from Figure 1 showing expected growth of Internet use in different regions of the world, some
data will be out of date almost before it can be reported. Tracking change over time is
complicated, due to large changes in scope and scale of use. Predicting the future is even more
difficult in view of exponential change and the multiplicity of impacts. After a brief discussion
of the data requirement for forecasting in this section, we review some data available currently
in sections 2, 3 and 4, pointing to its sources and giving some example outputs. Section 5 then
considers the strengths and weakness of types of available data for tracking impacts of e-
business, noting particular data gaps and provides suggestions for compensating for this lack of
data including drawing on non-traditional sources of data. The paper concludes with some
recommendation on transport metadata, requirements for tracking e-business impacts and

1.2 Data Needs for Forecasting
Both the rapid speed of change and the changes in society due to the information revolution in
general, poses special challenges for forecasting the future of e-business and assessing its
impacts. The traditional processes of collecting information over time, describing a base case
and projecting of future trends, or assessing change scenarios, encounters problems in all stages.
Problems arise in comparing information year-to-year, where scope and scale change, with the
description of ‘the numbers of users and uses’ at a given point in time becoming rapidly
outdated. Projection of trends, which resemble exponential growth curves rather than a linear
trend, is difficult. Change scenario assessments are based on impacts of a particular change of
interest ‘if other things are unchanged’, yet the only certainty about the future at the moment is
that many things will change.
These challenges apply to studies of impacts on the economy in general, but are greater in
studies of impacts in specific industries, such as transport. More detailed information is required
and more detailed outputs are expected. Almost always such studies are looking for sufficiently
detailed insights on future conditions to allow plans to be put in place. This requires predictions
to be linked closely to time frames and specific characteristics of localities.

2 AVAILABLE DATA AND SOURCES – STATIC/SEMI-STATIC
2.1 Infrastructure
While most data is time dependent, that which describes systems or situations that change
slowly over time may be considered almost static in comparison to other rapidly changing
items. For example, transport networks may remain virtually unchanged over a five to ten year
period, with changes being small adjustments for capacity or links. In contrast, while basic
telephone networks are in place across Australia, telecommunications networks are still
expanding services, so still need to be classified as varying.
Transport Networks
Network data adds connectivity, type of link and link capacity information to geographic
mapping data of roads and railway lines. The road authorities in each state hold complete
network data for their states often augmented by road condition data. For example, the
Transport Data Centre [TDC] from the New South Wales Department of Transport is now
conducting their fourth Household Travel Survey, compiling information on travel trips,
purpose, sources and destinations. The TDC is also collecting data for a Commercial Transport
Study [CTS] to update their Commercial Vehicle Survey [CVS] conducted in 1991/1992. The
expected outputs from this data are trip tables of commercial vehicle flows and available
regional commodity flows between industries to produce travel zone level trip tables that are
predictable [TDC, 2000].
Additionally, relevant transport authorities hold networks for future planning. Both commercial
providers of information and providers of emergency services hold urban networks information.
A larger number of organisations hold highways and major link networks. However, to the best
of our knowledge, there is not a detailed road network in use that covers all of the 813,769
kilometres of road open to general traffic across Australia [ABS, 2000f]. Table 1 from the
National Road Transport Commission showing the distribution of roads across Australia in 1996
shows that such a network would be a massive undertaking.

Linking capacity and linking condition may be particularly relevant to assessment of the future
ability of the road or rail system to accommodate future e-commerce. This might be applied to
consideration of capacity of local roads for urban freight in cities or to measure highway or
railway capacity for inter-urban freight movements. A recent American study by Southworth
and Peterson [2000], has assessed the overall freight capacity across the network in North
America and identified potential bottlenecks.
Transport Facilities
These include both public and private facilities such as ports, airports and intermodal
interchanges. AVSTATS the Department of Transport and Regional Services’ database
[DOTRS, 1999] provides information about both airport location and current traffic. Figure 2
gives an example of the annual aircraft movements from Australian airports in 1997 to 1998.
Data and Data Source Issues Working Paper 5
CSIRO & QUT Page 5
Figure 2: Annual Aircraft Movements From Australian Airports in 1997-98.
[Source: DOTRS, 1999]
Intermodal Road/Rail Terminals. Data available from rail/terminal operators on infrastructure
and networks includes static information on location and capacities as well as Operational Data
such as:
• tonnages in/out and number of containers in/out;
• train performance [on-time arrivals];
• availability of freight to customers [on-time performance];
• road truck movements in/out; and
• road truck turnaround times.
2.2 Socio-Demographics
It has been noted by numbers of authors, [for example, Stimson et al., 1999], that the structure
of Australian households is changing over time with a general ageing of the population and a
move to smaller households. However, such change is slow relative to the rate of change in e-
commerce uptake. Thus socio-demographic base data may be considered as static at least
across the five-year period between census collections.
ABS Census of Population and Housing
The Australian Bureau of Statistics Census of Population and Housing [ABS, 2000b] is carried
out every five years and is the only complete enumeration of the entire population of Australia.
Thus, apart from the value of the data in its own right, it provides the basis necessary for
expanding information collected in surveys by ABS and others to estimates for the entire
Data and Data Source Issues Working Paper 5
CSIRO & QUT Page 6
population. Data is collected for households and individuals and the dwellings in which they
live.
The census data is available via the product CDATA96 [ABS, 1997] which includes mapping
facilities to link socio-demographic information to location. Table 2 shows a sample of
numbers of people within age groups for some postcodes in New South Wales, Australia.

2.3 Industry and Workplace Locations
We argued in Working Paper One of this series [Smith et al., 2000] that change to a knowledge
based economy or information age would result in changes to types of industry, occupations and
job locations. However, these changes will be slower than many other changes due to uptake of
e-commerce. Thus data gleaned from the census and other ABS special collections might be
considered as approximating to static over five- year periods.
Journey to Work Tables
Sets of special tables showing origins and destination of work trips by mode of travel together
with gender, occupations and industries of the workers are derived from the Journey to Work
[JTW] question on the ABS census [ABS, 2000b]. They are available from ABS and state
department of transport for capital cities and surrounding areas at travel zone level [larger than a
Census Collector District but generally smaller than a postcode area]. Apart from their use in
tracking work trips the destination information is also useful for mapping industry by location.
Most other information on workers and industries from the census is linked to home location.

2.4 Commodity Flows
In common with workplace and industrial locations considered above, commodity flows are
likely to change with a rise in e-commerce. It is possible these changes may occur within a
five-year framework. However, they are included in this section because even though change
may be rapid, data collection and update of Input/Output tables to reflect that change will be
Data and Data Source Issues Working Paper 5
CSIRO & QUT Page 8
slow. Thus they are of value as baseline statistics rather than as a source of dynamic
information.
3 DATA AND SOURCES – DYNAMIC RE: PERSONAL ACTIVITY
Examples of available data for tracking activities, which may change rapidly within a five-year
period, have been divided for convenience into those relating to personal activity reported here
and those relating to business activity in the next section.
3.1 Personal Internet Usage
Data pertaining to personal Internet use is varied, dependent on the sources and relevant time
frame, due to the rapid explosion of personal computers and Internet access introduced into
Australian households. In the year prior to August 2000, the ABS [2000e] recorded an increase
from 48 to 54 percent of Australian households having personal computers. During this period
access to the Internet also increased from 23 to 34 percent of Australian households [ABS,
2000e]. Generally, computer ownership and Internet access is more predominant in
metropolitan areas than in regional areas.
In December 2000, Nielsen NetRatings [2001], estimated that Australian household accessed
the Internet for up to seven hours per month, visiting up to 14 Internet sites a month, for up to
28 minutes per site.

The most popular online purchases for the year ending in August 2000, were books and
magazines [27 percent] and music [also 27 percent]. Over half of the online purchases were
sourced from within Australia, 33 percent exclusively from overseas and 13 percent, a
combination of national and internationally sourced purchases. Eighty-five percent of all online
purchases were paid for online with credit cards [ABS, 2000e].
3.2 Making Personal Trips
Household Travel Surveys
The TDC from the New South Wales Department of Transport is now conducting the fourth
annual wave of their ‘continuous’ Household Travel Survey, compiling information on day-to-
day household travel trips in the Greater Sydney Metropolitan Region [GSMR]. Data collected
includes information on trip details, from origin to destination with travel times, duration and
distances, modes of transport, fare type, ticket cost, trip purpose and socio-demographics of the
survey participants. As the survey was designed to allow comparison with earlier surveys in
1981 and 1991, changes over 10 year periods can also be tracked. Figure 5 depicts the change
in distances travelled and the number of trips in relation to trip purpose from 1991 to 1997. The
largest increase for kilometres travelled are for personal business, social/recreational and then
passenger purposes, while the greatest increase in the amount of travel trips are for passenger
requirements, social/recreational and educational/childcare purposes [TDC, 1999]. Of particular

interest in relation to e-commerce is a 16 percent rise in distance travelled for shopping trips is a
fourfold increase over the four percent rise in numbers of trips. The TDC data also show a
growth in multi-purpose trips, for example, shopping while dropping someone at a station.
Substituting such shopping with e-shopping deliveries would increase rather than decrease total
trips.

Activity Surveys
Activity surveys differ from travel surveys in that they emphasise the activities undertaken at
different locations or the ‘stops’ made by persons surveyed over a day. Thus, they acquire
richer information about daily lifestyles than the simple trip purpose obtained by travel surveys.
The Victorian Activity and Travel Survey [1999] is conducted by the Transport Reseach Centre
[TRC] at the Royal Melbourne Institute of Technology [RMIT]. On average, about 5,000
households respond to the survey each year. Household details, personal details and the
activities undertaken at ‘stops’ during a day of travel are recorded. This yields a total of
approximately 12,000 person records and 50,000 stop records per year [TRC, 1999]. Since the
survey covers all 365 days of the year, both daily and seasonal variations in travel and activity
patterns can be observed. Figure 6 shows variation by time of day and season of the year in the
population of Bayside, a predominantly residential area along Port Philip Bay, 14 kilometres
south of the Melbourne CBD. Largely, people leave the residential area to work elsewhere
during the day.

3.3 Motor Vehicle Use
The ABS conducted a survey of motor vehicle use for the year ending in July 1999 [ABS,
2000d]. This is the second annual survey of this type, with information collated quarterly. For
the year ending in July 1999, 51 percent [70,267 million kilometres] of personal travel trips on
Australian roads were by passenger vehicle. Other passenger vehicle travel was for trips to and
from work [24 percent] and for business use [25 percent]. Vehicles registered in the Australian
Capital Territory and the Northern Territory recorded the highest average vehicle usage for
private purposes while vehicles registered in South Australia recording the lowest average
private purpose vehicle usage [ABS, 2000d].
3.4 Tourism Data
Inbound International Visitors
International Visitor Survey: The International Visitor Survey [IVS] draws on personal
interviews with 20,000 overseas visitors aged 15 or more, departing from major Australian
airports [Sydney, Melbourne, Brisbane, Cairns, Perth, Adelaide and Darwin] each year. It is the
most comprehensive source of information available on the travel patterns of visitors to
Australia. Summary information is published on a quarterly basis, while detailed results are
published for each calendar year. In addition, a large range of unpublished data is available on
request from the Bureau of Transport Research [BTR, 2000b].

Overseas Arrivals and Departures [OAD] is an ongoing monthly, quarterly and annual profile
of the characteristics of travellers to and from Australia from the ABS [ABS, 2000c]. In the
month of December 2000, there were 565,700 visitors arrive in Australia, which is a 23 percent
increase on the amount of visitors arriving in Australia the same month 1999. New South
Wales, Queensland and Victoria were the three most popular states visited.

Domestic Visitation
The National Visitor Survey [NVS] replaced BTR’s earlier Domestic Tourism Monitor in
January 1998. The NVS involves interviews with approximately 80,000 Australian residents
aged 15 years and over, each year. Domestic travel is by far the largest part of the Australian
tourism market, and the NVS provides details of the travel patterns and behaviour of Australian
residents. Details are obtained of all travel in Australia, including trips involving nights away
from home, as well as daytrips and trips by Australians overseas. Results from the survey are
published on a quarterly and calendar year basis, with a further range of unpublished data
available for detailed analysis from the Bureau of Transport Research [BTR, 2000c].
Holiday and leisure travel, business travel, visits to friends and relatives, and other types of
tourism are included. Previously unavailable data, such as domestic tourism expenditure and
activities on trips, as well as improved regional data, are now available from the NVS. Example
outputs are given in Table 3.

4 DATA AND SOURCES – DYNAMIC RE: BUSINESS ACTIVITY
4.1 Telecommunications Networks and Facilities
Data on the distribution of telecommunication services can be obtained from Telstra’s White
Pages, Yellow Pages and other telecommunication organisations. Coverage is Australia-wide
since all businesses paying rentals on their telephone service are included. Each entry usually
includes the business name, street address, suburb/town, postcode, type of business, as well as
one or more ASIC industry codes [ASIC, 2000]. Where multiple entries for a business location
occur, the Telstra software usually identifies duplicates to avoid double counts.
Tele-services data is updated frequently allowing longitudinal studies of change to be made.
Moreover, since tele-services are listed at the level of the business location, the resolution of
employment distribution can be estimated down to the business address or PABX level.

The use of mobile telephone information to track both personal and business activity is currently
being investigated in both Japan and America. As the mobile phone registers in a new cell, the
user is tracked. Apart from obvious concerns about privacy implications of such tracking,
accuracy of tracking also depends on cell size. However, if both these problems can be resolved
this may provide a rich source of dynamic data in the future. Especially as such phones and
other mobile devices are used for e-commerce transactions.
4.2 Business Internet Use
Figure 9: Australian Businesses with Computers, Internet and Web Sites/Home Pages, 1993 - 2000.
[Source: ABS 2000a]
The ABS has collected information in the financial years ending in 1994, 1998 and 2000 from
Australian businesses to ascertain their use of information technology. The survey, entitled
Business Use of Information Technology [ABS, 2000a] has evolved from collecting data on
computer use to measuring the extent and uses of Internet and web technologies. During this
period the growth of computer use in Australian businesses has expanded from 49 percent to 76
percent. Statistics collected for the financial periods ending in 1998 and 2000 reveal that the
proportion of businesses having access to the Internet has nearly doubled and the proportion of
Australian businesses with web sites or home pages has tripled [ABS, 2000a].

4.3 Freight/ Commercial Vehicle Activity
ABS Motor Vehicle Use: In the year preceding July 1999, loaded freight vehicles travelled
19,905 million kilometres within Australian and carried 1,421 million tonnes of goods. This
represents an increase of five percent of the area travelled and 11 percent of total tonnes carried
the previous year. Articulated and rigid trucks carried the largest proportion of freight [653 and
660 million tonnes respectively, with light commercial vehicles [LCV] carrying 107 million
tonnes of goods [ABS, 2000d].

Registration Data: Vehicle registration and licensing databases show locations and numbers of
registered vehicle types by location. While they provide information on the passenger fleet they
are of particular value in the e-business context in tracking changes in numbers and types of
commercial vehicle and also in holders of commercial vehicle licences. Individual states and
territories hold these databases. In addition, the ABS also collects the data to report on an
Australia wide basis as shown in Table 4 below.

Interurban Freight
FreightInfo is an ACCESS based database [FreightInfo, 2000]. This database relies on data
supplied by companies which make up the entire supply chain. It provides, tonnage by
commodity and mode for each origin-destination pair. The database uses 134 zones and includes
freight flows to and from Australia, as well as those within the country.
Ad-Hoc and Industry Specific Freight Survey Data: Regional freight studies have been
undertaken on ad-hoc basis across Australia. For example, the Southern Cairns: Integrated
Land Use and Transport Study by Queensland Government [1999], gives an overview of current
trends in Far North Queensland. The study investigates future land use and identifies future
transport needs in order to develop an integrated strategy to meet likely needs [Queensland
Government 1999].
Specific Industry Studies: Studies to investigate demand for specific industries such as a series
of forestry, cattle, cotton and sugar studies in Queensland to highlight the specific needs and use
of roads by industry types.
Data and Data Source Issues Working Paper 5
CSIRO & QUT Page 19
Weigh Station Data: Road Authorities such as Main Roads in Queensland, The Roads and
Traffic Authority in New South Wales and VicRoads in Victoria collect weigh-in-motion data
on heavy vehicle characteristics such as vehicle type and weight per axle groups.
Urban Freight
Consideration of changes in the urban freight task is particularly important in estimating the
impacts of e-business on the road system and vice versa. For example, will e-commerce add to
congestion and equally what will be the impacts of congestion on e-commerce? Until recently
transport planners concentrated on commuter travel. Estimates of future demands were
modelled on passenger transport needs and the extra demands of freight were simply ‘loaded
onto the network’. However major freight studies have carried out for example:
SEQ/Brisbane metropolitan freight study, includes roadside interview survey data, with details
such as mode, commodity, origin, and destination.
Cordon Counts in all cities and Automated Vehicle Counts: measure numbers of vehicles,
vehicle type, or number of axles, speed, by time of day and are routinely collected by road
authorities in all states.
Commercial Vehicle Study: There is now growing realisation in view of the increasing
importance of commercial traffic and the need to estimate traffic impacts across the day and not
just at commuter peak periods. In the context of development to a new travel model for Sydney
the New South Wales TDC are carrying out a study of commercial traffic. It is expected that the
study, in line with their household travel study, would provide ongoing data to monitor
commercial vehicle traffic growth [TDC, 2000].
4.4 Air and Sea Freight State Trade Statistics for each port are held by state transport departments. These normally will
normally include tonnage by commodity flows through each port.
Databases of Freight are maintained by the BTE. For example, these databases hold particulars
of freight loaded and discharged by coastal vessels at Australian ports [BTE, 2000a]. In general,
the data is unpublished and reported via BTE publications. The following figure is an example
of the sort of information available from such sources.
Data and Data Source Issues Working Paper 5
CSIRO & QUT Page 20
Figure 14: Coastal Freight Loaded By State Compared By Year 1998 - 1999.
[Source: BTE, 2000a]
In a similar manner databases for airfreight are held. Some examples are discussed below in the
context of exports
4.5 Market Data
Exports: Cargo Statistics
As can be seen from Table 5 while the sea freight carries a far higher tonnage of freight,
airfreight is of relatively greater value.
Table 5: Commodity Exports by Mode 1997-98.
[Source: BTE, 2000b]
Moreover, while the BTE [2000b] reports that Australia exported 64 different commodity
groups by air in 1998 based on the two digit commodity group codes of the ABS. Vegetables
and fruit, at 81.8 thousand tonnes, comprised 27 percent of the total exports and together with
Data and Data Source Issues Working Paper 5
CSIRO & QUT Page 21
the next two largest commodity groups, fish, crustaceans and molluscs and meat and meat
preparations account for just under half [47 percent] of the total weight of air freight exports.
In terms of the value of exports, gold and non monetary make up 36 percent of the total [$7.6
billion] with the next clear category being office machines and automatic data processing
[ADP] equipment 6.6 percent [$1.4 billion].
E-commerce may increase market access for the produce fish and meat. As this makes up the
largest volume of exports, hence, data for monitoring airfreight is particularly important in
considering capacity bottlenecks. In contrast, the export dollars won from an increase in sale of
ADP equipment will be sufficiently important to want to ensure the transport of such goods is
expedited. While outside the scope of this paper considering data sources, we note that the BTE
paper from which this information is drawn considers supply and demand balances in airfreight
to Asia.
5 DATA LIMITATIONS AND SOLUTIONS
5.1 Data Gaps
The diverse data sets reviewed above have one element in common. They are all secondary data
sets collected for other purposes. Thus in line with all secondary data sets, they are planned to
meet other requirements. Thus, it is not surprising that the special data requirements for
tracking e-business impacts on transport are not met.
Road freight flow data is particularly limited. Most data on freight vehicles has been collected
for regulatory purposes and thus while types of vehicles and mass/volumes carried are recorded,
there has been less interest in tracking the type of goods carried. Commodity flows are
measured for economic reasons. But as noted, input-output tables are held at levels of spatial
aggregation far too course for predicting traffic movements. For example, an entire city can fall
within a single commodity flow zone. Data about commercial vehicle movements related to
services rather than freight are even less detailed.
To measure changes to transport demand due to e-business, data about network flows of specific
goods and services is needed. For example, expectation of increased deliveries in suburban
streets can only be tested if such trips are measured. Likewise, increases can only be attributed
to e-business/e-commerce if a causal link to provision of those goods or services can be
established. This requires detailed identification of services and goods delivered. It is also clear
that e-business has significant potential to change the mix as well as the amount of goods and
Data and Data Source Issues Working Paper 5
CSIRO & QUT Page 22
services delivered. Planning by both private industry and government authorities require this
information for infrastructure planning that can range from appropriate loading bays though
modal interchanges to highways.
The other freight modes, air, rail and sea, collect somewhat better data on goods carried.
However, in general, the level of data is better for bulk commodities that are less subject to e-
business change, such as coal or wheat. In other cases, both privacy and commercial
considerations make abstraction of data, from, for example bills of lading, impractical.
Passenger Travel Data: In general better data is available to track travel by people. Peak hour
traffic due to travel-to-work has traditionally been measured to plan transport infrastructure and
services for cities. This type of network flow data is now being expanded and enhanced as
interest grows in both applying transport demand management to limit increasing traffic and in
the overall environmental impacts of travel. Studies such as the Victorian Activity and Travel
Survey described in section 3.2 can provide a sample of activity for strategic modelling.
Individual in-depth studies target local area shopping. However, the detailed level of activity
data needed to track shopping trends or leisure activities and relate them to specific localities is
not available.
Tourism Data Collections: have targeted accommodation in terms of visitor nights. Although
these collections provide quite good estimates of visits to popular destinations but are less
valuable for destinations ‘off the beaten track’. These sampling limitations mean that increases
in such tourism due to e-commerce marketing will not be picked up. Similarly tourism travel by
air is better measured than tourism travel by car. The increases in car tourism to regional areas
may thus be missed. Moreover, an emphasis on accommodation may miss the impact of
passing traffic using services from meals to specific tourism attractions.
Timely Data: Most of the data sets described above are collected at intervals. Often complexity
and detail of the data set is inversely proportional to the frequency of collection. For example,
the ABS Census of Population and Housing is collected at five-year intervals, the ABS Survey
of Motor Vehicle Use is annual and some trade figures are available quarterly. The entire
Internet revolution has occurred between the 1996 and 2001 census. Thus, annual changes in
both the scope and scale of e-business impacts have been too large to use annual collections to
assess trends.
While e-business technologies themselves have resulted in continuous data collection by
devices from e-tag readers for tolling to bus ticketing machines, this data has not yet been
Data and Data Source Issues Working Paper 5
CSIRO & QUT Page 23
systematically applied for wide scale assembly of data for tracking e-business impacts beyond
their specific applications.
5.2 Collection of Appropriate Data
When secondary data proves unsatisfactory the traditional response is to recommend specific
purpose collections, but, this is yet another situation related to impacts of e-business where
traditional solutions do not apply.
Two major data requirements for assessing impacts are:
• frequent update of data, in line with rapid change ;and
• broad spatial coverage to allow for differences across cities regions and the nation.
The expense of special purpose collections with such a temporal and spatial scope could not be
justified. It would be both more effective and efficient to:
• seek modifications to existing data collections to target necessary information;
• make better use of data collected continuously by electronic devices; and
• explore the use of multiple and complementary sources of data to build information.
None of these solutions is straightforward.
Modifying Existing Collections: There are always problems in adding questions to existing
survey instruments. While both the TDC in New South Wales and the TRC in Victoria are
including questions regarding Internet use in their updated surveys, the degree of detail that can
be requested is limited within a total travel survey. Even the NOIE specific surveys of Internet
use face limitations in distinguishing amounts and types of use. For example, a common
solution in internet-use surveys, both here and overseas, is to group shopping that results in
purchases with Internet ‘window shopping’. However, a clear distinction is needed for
assessing impacts on transport and further information about whether that purchase replaced a
store trip and, if so, the location of that store. Further, the answers to such questions would need
to be held individually for each purpose rather than aggregated purposes.
Another difficulty applies when obtaining Internet information in any survey, which extends
over time. It is reasonable to assume household shopping patterns will be not vary significantly
over the time between the survey of the first and last households in a travel survey, but, this may
not hold where internet opportunities vary rapidly over time. However the value in having
internet use questions linked with travel data would justify special efforts in question design and
sampling.
Data and Data Source Issues Working Paper 5
CSIRO & QUT Page 24
Collecting extra information in commercial vehicle use collection also faces a range of
difficulties, including issues of commercially sensitive and proprietary information. However,
at least in some collections there is loss of detail in data processing rather than collection.
Types of commodities carried are grouped for convenience because of sample size constraints.
Further investigation may show that more detail in some categories of freight might be obtained
from existing samples.
Better Use of Electronic Data: E-business systems are generating masses of data daily. In
numbers of cases the massive volume of data seems to defy use for other than its primary
purpose. However, an important resource is being lost.
In addition to continuous collections devices directly related to transport itself, in intelligent
transport systems and logistics track and trace applications, there are a range of relevant data
collected by business systems that update change as it happens. Concerns about privacy and
commercial sensitivity in use of such data sets will need to be addressed via access controls and
reporting allowed. Figure 15 shows an example of the use of up-to-date data sources, in this
case, telephone connections as a proxy for concentrations of employment. Census journey-to-
work data, where available, gives better estimates but can only be used to track change at five-
yearly intervals.
Figure 15: Telephone Services to Household Ratio to Estimate Regional Employment.
[Source: McNamara et al., 2000]
Data and Data Source Issues Working Paper 5
CSIRO & QUT Page 25
Data Fusion: However, the most useful approach would involve a mix of the methods above
and, particularly, innovative approaches to the use of data from multiple sources. This could
involve combination of transport data such as commercial operators information on vehicle
schedules and road authorities information on traffic for improved intelligent transport systems
applications. However a wider range of business data such as Internet purchase information
would also be relevant. It is usual to stress the confidentiality concerns in use of such sources,
but equally, or perhaps even more important, are the needs:
• firstly to ensure the data can be extracted in the manner needed with minimal cost and
disruption to the holder; and
• secondly to demonstrate some advantages, beyond payment in most cases, for the
organisations providing data.
The difficulties are not trivial but not in-surmountable. Improved standard of data
interoperability will be required. Data models will be self-describing, allowing them to be
transferred readily between systems. Numbers of e-business technologies such as intelligent
agents to automatically source and repackage information as required will help. Unfortunately
there is no ‘technology’ to convince businesses to share data. They will need to see direct
returns in terms of better transport infrastructure and services.
5.3 A Systematic Approach to Data Shortfalls
We have found there is insufficient data available to accurately track the current impacts of e-
business and transport. However, there is sufficient data and experience to see that changes are
occurring. Transport supply and demand management require a capability to go beyond mere
tracking of change, to prediction of change, and to an understanding of the factors driving
change.
In particular data must be:
• up-to-date and comparable over time,
• geographically specific to allow for locational diversity; and
• have sufficient contextual information for analysis of impacts.
No one central data collection could satisfy these requirements. Figure 16 is a schematic
impression of the sort of data system needed.
Data and Data Source Issues Working Paper 5
CSIRO & QUT Page 26
Figure 16: Data Management System for Assessing e-Business Impacts on Transport.
An up-to-date meta-data set holds information about available data and access processes. The
data is then sourced as needed, with provision of payment to the holder, where appropriate, and
then prepared for analysis. New web based access systems mean that such systems are now
theoretically viable. A system of this type would be very helpful for both industry and
government in successful handling of the transport impacts of e-business.
