Evaluation of Existing Roadside Safety Hardware Using Updated Criteria. Volume 1. Technical Report. NCHRP Web-Only Document 157

摘要

The objective of this project was to evaluate the safety performance of widely used nonproprietary roadside safety features by using MASH. Features recommended for evaluation included longitudinal barriers (excluding bridge railings); terminals and crash cushions; transitions; and breakaway supports. Evaluation methods included, but were not limited to, engineering assessment, simulation, full-scale crash testing, pendulum testing, and component testing. Where practical, cost-effective modifications to systems that do not meet the new criteria were recommended for future evaluation.
