New Australian study finds behaviour change missing link in sustainable transport planning

Melbourne, Australia, 25 May 2026: A major new Australian study finds that people are most likely to change how they travel during key life moments such as moving house or changing jobs, and that policies which make public transport faster, easier and better connected are far more effective – and publicly supported – than measures focussed on simply building more infrastructure. The study also shows that tailored approaches for different traveller groups deliver better results than one-size-fits-all solutions.

The final report from the Institute of Transport and Logistics Studies (ITLS) University of Sydney, the Department of Infrastructure, Transport, Regional Development, Communications and the Arts, Queensland Transport and Main Roads, through the iMOVE CRC and led by ITS Australia draws on national and international evidence and a large-scale survey of more than 4,000 people across seven countries, including over 1,000 Australians. It provides practical guidance for governments, transport authorities and operators on how to design initiatives that drive lasting shifts towards sustainable travel.

The research identifies 25 actionable initiatives linked to real changes in travel behaviour, including employer-supported public transport, improvements to public transport networks, active and micromobility options, flexible work arrangements and targeted communication campaigns.

Public support is strongest for initiatives that improve affordability and access to public transport, such as free local services, fare discounts and loyalty rewards. Road pricing and congestion charging attract more mixed views and depend heavily on perceived fairness, transparency and clear reinvestment in better transport options.

ITS Australia’s CEO Susan Harris calls out the value of the findings. “What makes this study so powerful is that it moves beyond theory into practical reality. We’ve long understood that lifestyle changes influence how people travel, but we haven’t been nearly intentional enough about designing transport systems to respond to those moments.” Said Ms Harris. 

“This research shows that behaviour change doesn’t happen in isolation - it depends on whether the right services, infrastructure and choices are available when people need them. That’s where transport planning must evolve.”

The report also segments travellers into three distinct groups with different needs and preferences, showing how targeted policy packages can improve effectiveness and equity across both city and regional areas.

Overall, the report provides an evidence-based roadmap for delivering scalable, fair and effective sustainable travel outcomes across Australia.
