Development of a collaborative vehicle collision avoidance system

Advanced systems for driver assistance in combination with new preventive safety systems offer great potential for collision avoidance, reducing accident severity and increasing occupant protection. This paper presents the development and evaluation of a system targeting to vehicle collision avoidance in emergency situations. The proposed system provides the nearby vehicles with information about possible accident involvement. The main feature of the proposed system is the wireless communication among vehicles during normal driving in case of emergency situations. The wireless communication is originated by a vehicle in emergency state while the vehicles in range get benefit of the transmitted information. The wireless communication packet is comprised of the type of the vehicle, which originates the transmission, the description of the current situation, and the geographical position of the vehicle which is provided by a Geographical Positioning System (GPS) module. The critical issues and other technical challenges in developing these systems will be explored.
