By incorporating the human factors interdisciplinary behavioural science into the design process, system designers can shape transport systems with a deeper understanding of the factors that influence human behaviour; this insight keeps people at the centre of the design process, informs the process with an empathetic approach to comprehending the why in road-user behaviour—and offers greater potential for incident/crash prevention. 

This article explores how the application of the human factors specialism contributes to designing safe road systems—toward the Vision Zero goal of zero fatalities and serious injuries within the worldwide road transport system.
