This report details the development of a MASH-compliant barrier system designed to protect vulnerable road users from motor vehicles. The growing presence of pedestrians, bicyclists, and other active transportation users necessitates improved safety measures on roadways. This research provides a comprehensive design for a crashworthy roadside barrier system intended for high-speed roads, specifically addressing the safety needs of non-motorized users of adjacent multiuse facilities. The report includes extensive supporting documentation, such as survey data, crash test results, technical drawings, and certification documents, crucial for implementation and FHWA eligibility.

This research report is a technical document aimed at transportation agencies and engineers. It provides a specific, detailed solution to a recognized problem in road safety infrastructure. The inclusion of extensive appendices with raw data, technical drawings, and certification documents suggests a focus on practical application and regulatory compliance for implementing the proposed barrier system.
