Abstract
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.
近年来，随着车辆数量的增加，交通事故的致命数量也在迅速增加，全球范围内对智能交通系统的安全服务进行了大量的研究和开发。为了减少交通事故，车辆与基础设施之间的合作(C2I: Car to infrastructure)和车与车之间的合作(C2C: Car to Car)备受关注。在本文中，我们介绍了WAVE(车载环境无线接入)技术，它是C2I和C2C通信的标准，如IEEE802.11p和IEEE P1609。在此基础上，提出了一种具有双唇无线装置的WAVE装置。通过双器件，WAVE系统有望提供稳定的运行、可靠的通信和更高的性能。为了验证WAVE系统的有效性，我们开发了典型的十字路口避碰场景和前后避碰场景安全应用系统，并给出了评估方案。
