A new approach for analysis on intersection accidents

This paper describes an approach developed to facilitate the identification of accident occurrence within the intersection zone. The zone was divided into five sections and accidents located according to the placement of the vehicles viz, approach, centre or departure. The distances of link accidents from the intersection were also recorded. It was found that 80 per cent of all accidents (intersection and links) occurred within 100 feet of intersections and 63 per cent of all accidents o#curred within the intersection zone. Within the intersection zone 25 per cent of the accidents were on the approach, 61 per cent in the centre, and 14 per cent in the departure. The distribution was markedly different for cross and tee intersections. Examination of accident types within the intersection zone found different types predominating in the different sections. The distribution of specific accident types varied individually across the five sections. For example pedestrian accidents were largely involved on the departure (a).
