Roadway intersections are recognized as more hazardous than any other location on the roads as the conflict possibilities are very high, which often result in higher frequency of fatal crashes. In this study, a logistic regression model was applied to identify the factors that might affect the fatality risk of a crash at urban intersections in Dhaka, Bangladesh. Our results showed that there was a general increase in fatality risk at intersections from 1998 to 2005. Single vehicle crashes resulted in higher severity than multi-vehicle crashes. Pedestrian, driver and passenger casualties were associated with higher fatality risks. Overturning and hit-pedestrian crashes also resulted in more fatal crashes at intersections. Off peak hour crashes increased the fatality risk while presence of police at intersections with or without signal decreased the probability of fatal crashes. Non motorized vehicles, heavy vehicles and motorized two wheel vehicles were associated with higher fatality risk whereasght vehicle crashes were associated with lower fatality risk. (A).
