In present telematics services, GPS receivers and navigation systems using existing telecommunication network are operated only as a simple unilateral service i.e. a self localization of the vehicle, traffic report and neighborhood information which is only provided from a base station. For an advanced driver-friendly and active-safety system, however, much more information should be transmitted between vehicle and another vehicle. This information is possibly status of the vehicles and road, or driver's condition, or surrounding information, which is determined by sensing and monitoring all contexts, etc. This system adopted event based communication system for stability and reliability of data communication, and event holding time replaced vehicle safety driving time. This system estimated safety driving time when irregularly information occurs. This system was composed by collision warning/avoidance system. Especially, safety driving time was determined by vehicle relative position and another vehicle information which are rapid turning and acceleration. This main purpose is to provide the driver adequate warning message in advance in order to avoid the possible collision. A system demonstrator is developed in order to get a test bench for collision risk assessment algorithms evaluation.
