DETERMINATION OF THE OPERATIONAL PERFORMANCE REQUIREMENTS FOR A ROADSIDE ACCIDENT COUNTERMEASURE WARRANT SYSTEM. VOLUME 1. EXECUTIVE SUMMARY. FINAL REPORT

The research was conducted to determine the operational performance requirements for a roadside accident countermeasure warrant system in terms of identification of the need for countermeasures and the degree of protection required as a function of highway design and operating characteristics. The majority of the work was unsuccessful attempts to collect adequate highway encroachment data. Measuring devices used were video tape recorder (VTR), guardrail encroachment monitor (GEM), camera/trigger wire, and camera/tape switch units. Available accident files and 203 accidents investigated in depth were analyzed to determine the severity of accidents as a function of vehicle type, speed, impact angle, and object struck.
