VEHICLE-TO-VEHICLE COMMUNICATION FOR COLLISION AVOIDANCE AND IMPROVED TRAFFIC FLOW

The purpose of this Innovations Deserving Exploratory Analysis (IDEA) project was to determine the performance requirements of a vehicle-to-vehicle communication and on-board processing system which would provide prediction and driver warning of potential inter-vehicular collisions, thus improving collision avoidance. The approach taken was unique in that the warning system developed allows vehicles to operate independently and without the control problems associated with platooning, but with the ability to utilize data from several vehicles ahead, unlike two-vehicle interaction systems. The impact of the developed advisory system is potentially large, since some 20% of all accidents are of the rear-end collision type and such accidents result in substantial loss of life and substantial cost in the form of delay and property loss. Researchers have stated that 60% of all rear-end collisions could be avoided if the driver were given an additional one-half second of warning prior to an incident.
