What actually changes driver behaviour? Why what works in one country can fall short in another

Designing safer roads must include an understanding of how people drive on them.

In this episode GHD’s Frank Penry (Senior Traffic Project Manager) and Sarah Dods (Technical Director – Advanced Analytics) explore how driver behaviour data is changing the way we identify risk and improve road safety.

Drawing on observations from Australia and the United States, they unpack how drivers in both countries respond differently to speed limits, congestion and emerging hazards, and why approaches that work in one country can fall short in another.

The conversation encourages listeners to look beyond crash data alone, using near‑misses and braking events to help reveal patterns of risk earlier and test whether safety interventions are actually working.

Listen for a practical perspective on how driver behaviour insights can support safer transport decisions.
