Development of Vehicular Communication (WAVE) System for Safety Applications

These years, there has been much research and development activity in safety service for ITS (Intelligent Transports System) globally because fatal accidents have been increasing rapidly according to spread of vehicles. In order to decrease traffic accident, cooperation between vehicle and infrastructure (C2I: Car to Infrastructure) and between cars (C2C: Car to Car) attracts much attention. In this paper, we introduce WAVE (Wireless Access in Vehicular Environment) technology that is under standardization for C2I and C2C communication as IEEE802.11p and IEEE P1609. Then we present developing WAVE device with dual lip wireless device. With dual device, WAVE system is expected to provide stable operation, reliable communication and higher performance. For the purpose of validity of WAVE system, we have developed typical safety application systems of crossroad collision avoidance scenario and front-tail collision avoidance scenario, and show evaluation plan.
