Abstract:

The objective of this project was to develop a method to prevent errant motorists from entering the median openings between parallel bridge structures. This project identified characteristics that could be used to target potential sites for implementation of a median opening protection system (MOPS). In this identification process, the research team completed a systematic approach analysis on the available crash data to determine these characteristics. Because of the risk associated with larger vehicles being involved with this type of crash, the research team was tasked with investigating both the crashes involving median opening areas and the crashes involving buses. Additionally, this project investigated readily available technologies for their application in a vehicle arresting system. This system would be implemented in median openings between parallel bridge structures and would arrest errant vehicles before they plunged into the hazard below the bridge. Last, the research team developed a MOPS using readily available technologies and evaluated the MOPS through full-scale crash testing.
