Reducing Urban Arterial Intersection Crashes Through Crash Typing Analysis: A Case Study

A previous paper proposed a simple method for identifying crash-prone locations that entails analyses of collision patterns along arterials and identification of clusters of crashes with common vehicle movements prior to the crash. This method assumes that crashes associated with specific traffic movements are more amenable to traffic engineering countermeasures than locations that simply have high numbers of crashes. The current paper describes how this crash typing analysis was applied to an arterial in the Washington, D.C metropolitan area and examines the effects of engineering countermeasures that were applied based on the analysis. This case study provides evidence that intersections with large numbers of crashes of a particular type can be good candidates for relatively simple engineering countermeasures that reduce crashes. Analyses that examined the treated intersections as a whole, as well as those that focused on types of crashes and approaches specifically targeted by engineering improvements, indicated that the treatments were effective in reducing both the overrepresentation of certain types of crashes and the annual numbers of specifically-targeted crashes.
