RECMODELER : EVALUATING COOPERATIVE COLLISION AVOIDANCE
RECmodeler is a modular simulation tool built to evaluate alert criteria for collision avoidance systems, including information that might be available from a vehicle-to-vehicle communications system. No assumptions were made about the specific communications system or available datum; the goal was to evaluate what data would be most useful. The single-lane, rear-end collision, lead-vehicle decelerating scenario was chosen as the best test case for demonstrating the effectiveness of the methodology. Software modules built to date include four different sensor models and a fuzzy-logic driver model. Communications can be limited by both distance and direction, in order to limit nuisance alerts. The results of this prototype evaluation indicate that alert thresholds based on velocity differences or deceleration can be more effective than those based on closing rate or following distance. The ability of the cooperative system to immediately alert to the risky actions of vehicles at a distance, prior to those vehicles actually posing a crash risk themselves, provides an extra level of performance relative to systems that alert based only on recognition of an imminent crash situation
