Abstract

Highway collisions are a leading cause of death and serious injury in developed and developing countries. Intersections are recognized as being among the most hazardous locations on the roads. Although crashes at intersections form about 35% of the reported accidents accounting for about 32% of traffic-related serious injuries and fatalities in Singapore, there is no known study that examines the factors contributing to the severity of these crashes. In this paper, the ordinal probit model was applied to crash data from 1992-2002 to investigate the role a variety of factors play in determining the severity of intersection crashes. This study shows that vehicle type, road type, collision type, driver's characteristics, and time of day are important determinants of the severity of crashes at intersections in Singapore.
