National Highway Traffic Safety AdministrationNTL-INTELLIGENT TRANSPORTATION SYSTEMS-Collision Avoidance Systems (Vehicles)NTL-SAFETY AND SECURITY-SAFETY AND SECURITYIntelligent Transportation Systems Joint Program OfficeIn 1996, over 1.8 million rear-end crashes occurred in the United States with approximately 2,000 associated fatalities and 800,000 injuries. Rear-end crashes accounted for approximately 25% of all police-reported crashes and 5% of all traffic fatalities. Forward Collision Warning (FCW) systems are now emerging that provide alerts intended to assist drivers in avoiding or mitigating rear-end crashes. This report describes activities undertaken by the Crash Avoidance Metrics Partnership to define and develop key pre-competitive enabling elements of FCW systems. These elements include the definition of specific crash type(s) that an FCW system should be designed to address, the resulting minimum functional requirements for such a system, and objective test procedures for evaluating the extent to which a particular system design provides the desired functionality. Establishing these key elements will enhance consistent countermeasure system implementation across manufacturers. This will result in improved customer understanding and acceptance and help to accelerate the implementation of FCW systems
