Abstract
Abstract Crossing busy intersections is one of the most demanding visuomotor skills a driver must master. The objective of this study was to investigate crossing behaviour of healthy older drivers and older drivers with Parkinson's disease (PD) on uncontrolled intersections, where drivers must yield the right-of-way to cars approaching the intersection before them. As part of a larger study, undertaken to evaluate the effectiveness of Advanced Driver Assistance Systems, nine older drivers with PD and nine healthy older drivers completed fourteen simulator rides of 25 km length through a virtual city (including segments of straight road, uncontrolled t-junctions and intersections with traffic). The driver's decision making and crossing behaviour on intersections during the first, mid, and last ride were assessed. Results revealed that, compared with healthy older drivers, older drivers with PD were more cautious in their decision to cross or not: They decided more often not to cross between cars and when crossing between cars they accepted a larger time gap compared to the healthy older drivers. This was congruent with their crossing behaviour as they took more time to initiate their movement and crossed intersections slower than the healthy older drivers. In addition, both healthy older drivers and older drivers with PD crossed the intersection faster when they experienced time pressure from cars approaching from the right. On intersections with visual obstruction, older drivers with PD accepted smaller time gaps between cars and their crossing speed was lower than when sight was not obstructed. When approaching cars from the right travel faster this might be risky crossing behaviour, but in this study the safety margins did not significantly decrease. The results of this study suggest that both healthy older drivers and older drivers with PD adequately interrelated their tactical decision making with their crossing behaviour, resulting in safe crossings.
