Objectives:

Use of virtual reality system to investigate road crossing behaviour in children and young adults (aged 19 to 30).

Methodology:

Trials were conducted in which vehicles passed at either a uniform speed (but with variable spacing), or with uniform gaps at the time they passed the pedestrian (but with variable speed).

Key Findings:

Road crossing performance was better in uniform speed rather than uniform distance trials.

This suggests that pedestrians base road crossing decisions on inter-vehicle distance rather than vehicle speed.

Themes:

Road crossing, behaviour, virtual reality

Comments:

Virtual reality was used to illicit more realistic behaviour (i.e. a sense of risk) compared to computer based simulations.
