The Department of Transport and Main Roads (TMR) provides Traveller Information Services, such as variable message signs (VMS), to inform road users of traffic and road conditions, enabling them to make informed travel decisions.

For example, in an event of a crash on a motorway, a VMS will present information that aims to warns motorists of potential issues and encourages motorists to make alternative route choices to avoid unnecessary delays and be potentially subjected to further risks.

However, there is not a clear understanding of the actual effectiveness the VMS is achieving in terms of behavioural change. This lack of clear understanding of effectiveness also applies to information presented to users through personal navigation devices, through radio broadcast or through other channels.

Greater understanding of the effectiveness of these mediums and how the effectiveness changes with different use of the mediums would enable more effective use of these tools for travel demand management.

This project aims to:

  • understand the effectiveness of existing traveller information services in influencing user’s travel decisions
  • develop and implement an evaluation methodology to measure the effectiveness of existing or future traveller information services
  • identify opportunities and solutions for the improvement of existing traveller information services to achieve greater travel demand management outcomes.

Research activities

As part of this research project, you will be involved in:

  • evaluating current literature reviews and data
  • developing, implementing and evaluating an evaluation methodology.


As a result of this research project, we expect the following outcomes:

  • a methodology for the testing and analysis of Queensland’s traveller information services
  • recommendations to improve existing methods of generating traveller information and information distribution channel
  • suggestions for future research to improve the use of existing technologies to generate traveller information.

Skills and experience

To be considered for this project, you should have a strong background in transport engineering.
