Bridge and tunnel strikes (BrTS) involve commercial vehicles, recreational vehicles, buses, and agriculture and industrial equipment. In the United States, the National Highway Traffic Safety Administration reports that bridge strikes alone top 15,000 a year. The overall objective of this project is to develop tools that facilitate collecting, analyzing, and communicating BrTS data to help state DOTs, public safety agencies, and the motor carrier industry prevent and mitigate the risk of BrTS by motor vehicles. Correspondingly, the team will: 1) develop a sustainable national clearinghouse for collecting and analyzing data, and communicating bridge and tunnel strike data and clearance information; 2) develop a data-driven method to evaluate the risk of a motor vehicle strike on any single bridge or tunnel; 3) develop prevention and mitigation strategies; and 4) develop a roadmap for state departments of transportation to implement.
