Roadside Safety Device Analysis, Testing, and Evaluation Program

This project provides TxDOT with a mechanism to quickly and effectively address high priority issues related to roadside safety devices. Roadway departure crashes represent over 50% of fatalities on Texas roadways each year. Roadside safety devices shield motorists from roadside hazards such as non-traversable terrain and fixed objects, thereby reducing injuries and fatalities associated with roadway departure crashes. There is a need to develop new or improved roadside safety devices that accommodate a variety of site conditions, placement locations, and a changing vehicle fleet, including motorcycles to further enhance the safety of the motoring public. The second edition of the American Association of State Highway and Transportation Officials (AASHTO) Manual for Assessing Safety Hardware (MASH) published in December 2016 will be used to evaluate the impact performance of the devices developed under this project. This document provides comprehensive procedures for the safety performance evaluation of roadside safety hardware. The MASH design impact vehicle is considered to be more representative than previous guidelines of the large class of light trucks, including sport utility vehicles (SUVs), on Texas roadways.
