THIS PAPER DESCRIBES THE APPLICATION OF A SEVEN-STEP CRASH PROBLEM ANALYSIS METHODOLOGY, AS DESCRIBED IN THE PRECEDING PAPER BY LEASURE (1), TO REAR-END CRASHES. THE PAPER SHOWS HOW MODELING OF REAR-END CRASH SCENARIOS AND CANDIDATE COUNTERMEASURE ACTION HAS BEEN USED TO ANALYZE VEHICLE MOTION AND DRIVER ACTIONS, DEFINE AND EXPLAIN COUNTERMEASURE ACTION, PREDICT
EFFECTIVENESS AND BENEFITS AND, ULTIMATELY, GUIDE FUTURE RESEARCH. THIS PROCESS MIGHT BE DESCRIBED AS A "FRONT-END" ANALYSIS OF REAR-END CRASHES AND THE PROSPECTS FOR PREVENTING THEM THROUGH THE APPLICATION OF ADVANCED TECHNOLOGY. THE DISCUSSION FOCUSES ON LEAD-VEHICLE STATIONARY CRASHES, THE LARGEST SUBCLASS OF REAR-END CRASHES. THE PRINCIPAL COUNTERMEASURE CONCEPT EXAMINED IS A HEADWAY DETECTION SYSTEM THAT WOULD DETECT "THREATENING" VEHICLES IN A VEHICLE'S FORWARD TRAVEL PATH.
