摘要：The proposed approach aims to identify "critical" road segments and to prevent a traffic jam before it actually occurs. Therefore, we will show that, for the estimation of traffic flo w dynamics, a purely density-based analysis does not suffice. Consequently, it is necessary to understand the nature of traffic b reakdo wn, which describes a spontaneous drop of the average velocity on a stretch of road; often, a breakdo wn spontaneously occur s without an obvious cause such as a co nstruction site or an accident. It is actually caused by misbehavior of human drivers in dense traffic. Therefore, we suggest using periodically emitted beacons to analyze the current traffic state. Communicating vehicles change their driving behavior in dense traffic and inform following vehicles about the discovery o f dense traffic. After a vehicle has changed its driving behavior, it is expected to be less likely the trigger of traffic breakdown. This makes our method different from many previous approaches that guide vehicles to less-congested routes to escape congestion.
