Evaluating the Effectiveness of Regulatory and Warning Signs on Driver Behavior Near Highway/Rail Crossings

The primary objective of this research project is to evaluate the effectiveness of regulatory and warning signs on driver behavior by analyzing the effectiveness of specific signage in reducing instances of stopped vehicles within the dynamic envelope of at-grade highway-rail crossings near roadway intersections. Specifically, the main objectives are to conduct a review of completed and ongoing studies that relate to using signage to improve safety; confirm, with the Louisiana Department of Transportation and Development (LADOTD), the list of locations with known problems of stopped vehicles within the dynamic envelope of crossings; equip the selected locations with traffic data collection devices and collect “before” data; install accompanying signage at selected locations; collect “after” traffic data; and determine the effectiveness of the signage through comparative analysis of “before” and “after” data.
