Abstract

This paper aims to explore three walking behaviors of older pedestrians that may increase their crash risks when crossing urban streets. Older and younger pedestrians' start-up delay in initiating a crossing and number of head turns during street crossing are observed at 30 pedestrian crossings in Seoul, South Korea, using video recorders. In addition, their estimation of the safe crossing distance to an approaching vehicle is collected in a survey. Our study shows that older pedestrians have a shorter start-up delay time than younger pedestrians, older pedestrians crossing streets turn their heads less frequently, and older pedestrians provide less reliable estimates about the distance of an approaching vehicle. Safety technologies, campaigns and environmental designs should target these behaviors to improve the safety of older pedestrians.
