Factors contributing to crashes at intersections and mid-blocks: Study of two-vehicle crashes at Australian Capital Territory

Intersections are recognized as being among the most hazardous locations on the roads. Therefore, many jurisdictions around the world have set specific targets for the reduction in the number of deaths and serious injuries resulting from crashes at intersection. To achieve these goals and enhance road safety require a better understanding of the factors contributing to crashes at these hazardous locations in order to develop more targeted countermeasures. This study examines the effects of traffic characteristics, roadway design, vehicle features, collision types and road user characteristics on two-vehicle crashes at intersections compared to non-intersections in the Australian Capital Territory. These factors will be explored using chi-square tests and subsequently modelled using the binary logistic regression model. The results showed that the distribution of crash types is different for intersections and mid-blocks. We found that several roadway, environment, traffic, and crash characteristics had differential effects on intersections and mid-block crashes.
