Abstract

During the last decade, traffic injury rates of elderly pedestrians in Singapore were more than twice of those for pedestrians of all ages. This paper aims to identify the factors and situations influencing the injury severity of elderly pedestrians involved in vehicle-pedestrian crashes. Six years of crash data from 2003 to 2008 containing about 805 elderly pedestrian crashes were analysed. The injury severity was modeled as a function of roadway characteristics, traffic features, environmental factors as well as driver and pedestrian characteristics using a random-parameter ordered Probit model that accounts for unobserved heterogeneities in the population.

RESULTS show that the likelihood of fatal injury is higher during night time. While the probabilities of fatal or serious injury are higher along high-speed roads and at three-legged intersections, the corresponding probabilities are lower if the crash involving elderly pedestrians happens at signalized intersections. Elderly pedestrians appear to be more involved in fatal and serious injury crashes when they attempt to cross the road away from any at-grade crossing facility or cross unlawfully within 50 m of grade-separated crossing facilities. Based on the findings of this study, specific countermeasures are recommended to improve safety of elderly pedestrians.
