Intersections are hazardous locations, especially in developing countries like Bangladesh where an increasing trend of injury severity in the past nine years has been observed. In this study, a partially constrained generalized ordered logit model is applied to a sample of crash data from 1998 to 2006 to determine the factors contributing to severity of intersection crashes in Bangladesh. We find that severity tends to increase when the crash occurs on an undivided highway, involves single vehicle, non-motorized vehicle, motorized two-wheeler, bus, truck or pedestrian. Severity also tends to increases when the intersections are located in rural areas, on dry pavement or during adverse weather. On the other hand, a crash is likely to be less severe when the intersection is attended by traffic police.
