In-Depth Investigation of Wrong-Way Crashes on Divided Highways in Alabama with Use of the Haddon Matrix and Field Observations

Abstract

Few studies exist on wrong-way driving (WWD) on divided highways. Earlier findings on contributing factors and countermeasures mostly have been on freeways. This study filled the gap through the conduct of an in-depth investigation of WWD crashes exclusively on divided highways in Alabama. Extensive efforts were made to analyze WWD crash data through the use of the Haddon Matrix and field observations. General issues, contributing factors, and countermeasures were identified through in-depth analyses of individual crashes and field review of crash locations and WWD entry points. On the basis of study conclusions, recommendations are made to reduce the possibility and severity of WWD on divided highways.
