Abstract:

This report documents a three stage project commissioned by the Baseline Committee, which commenced in
mid 2002. The overall aim of this three-stage project was to explore existing data collection systems in
Victoria that collect behaviour, travel and exposure data, identify gaps in these data collection systems and
recommend collection measures to complement the existing data collection surveys. On-road behaviour is a
key variable in road safety research for both the design and evaluation of road safety initiatives. This type of
data traditionally utilises observational collection methods. Exposure data is traditionally measured using
travel surveys and is vital in road safety research as it provides an accurate measure of risk exposure.

The research findings are reported in three stages, each stage evolved from the findings and
recommendations of the previous stage. The aims of each stage of this research program were as follows:

  • Stage 1 - Review current collection of behaviour, travel and exposure data in Victoria and relevant
    iterature and experiences from other regions;
  • Stage 2 - Prepare a survey design and implementation plan for collection of behaviour, travel and
    exposure data in Victoria; and
  • Stage 3 - Facilitate a Behaviour, Travel and Exposure Forum with key stakeholders regarding a
    collaborative approach to data collection and to establish MUARC’s future role in this area.

The Stage 1 section of this report is a review of the current data collections and surveys conducted within
Victoria that identify behaviour, travel and exposure patterns. This review identified a current lack of
systematic collection of this type of data within Victoria. Following this, in Stage 2 the follow issues were
explored: identify the essential data to be collected; identify what essential data is not currently collected;
propose methodologically sound data collection methods for this data collection; and provide estimates of the
cost associated with collection of this data. While exploring these issues it was discovered that the
Department of Infrastructure (DOI) were in the process of designing and implementing a travel and exposure
survey in the Melbourne Statistical Division and that VicRoads was exploring the collection of comparable
data in rural Victoria. Stage three of this report documents the resulting Behaviour, Travel and Exposure
Forum conducted by MUARC bringing together these key stake holders. This includes an umbrella
framework designed by MUARC and presented at the forum that outlines a data collection strategy for
collaborative Victoria wide behaviour, travel and exposure data collection by DOI, VicRoads and MUARC.

Following on from the detailed background work conducted in earlier stages, one of the major successes
arising from this research has been the agreement reached by all stakeholders on the value of a collaborative
approach to the collection of behaviour, travel and exposure data, and the agreement of an optimal sampling
methodology. MUARC’s role in this collaborative approach will assist in providing a more complete
landscape for the collection of behaviour, travel and exposure data in Victoria.
