Abstract

Older drivers appear to be over-involved in collisions with other vehicles while turning. A simulation experiment examined the ability of older drivers to make turn decisions. Active drivers aged between 24-37 years and above 70 years made judgments on whether they would turn between oncoming traffic. Gap times between vehicles and the oncoming traffic speed were manipulated on computer generated graphic projections. Older drivers were far more conservative in their decisions to turn and in some conditions the decision to turn was delayed. They also appeared to rely more heavily than younger drivers on gap distance to determine whether to turn. This evidence suggests that some older drivers may use a different model for turn decisions based on motion perception abilities and information processing speed.
