As the number of pedestrians, bicyclists, and users of other active transportation modes continues to grow in the United States, state departments of transportation and other transportation agencies are seeking to improve how these users are accommodated on or adjacent to our nation's roadways.
NCHRP Research Report 1116: Development of a MASH Barrier to Shield Pedestrians, Bicyclists, and Other Vulnerable Users from Motor Vehicles, from TRB's National Cooperative Highway Research Program, provides a detailed design for a crashworthy roadside barrier system for use alongside high-speed roadways that also addresses the needs of nonmotorized users of adjacent multiuse facilities.
Supplemental to the report are:
Survey, Crash Test Data, and Supporting Certification Documents: Appendices A, C, D, G, H, and I;
Technical Drawings and Information for FHWA Eligibility Filing: Appendices B, E, F, and J;
