路車間通信システム評価のためのハードウェアインザループシミュレータの開発

摘要

This paper describes a simulation technology for Road-To Communication (RVC) system with DSRC (Dedicated Short Range Communication) and IR (Infrared). In the development of RVC system, we need to evaluate/test the developed system in various traffic situations. But it is difficult to carry out these evaluations and tests including wireless communication between moving vehicle equipped with wireless on-board unit(OBU) and road side unit(RSU) in the real world, because of the cost and safety problems. In order to solve this problem, we have developed hardware-in-the-loop simulator for RVC system in cooperation with real DSRC and IR system and made it possible to do evaluations in the laboratory.%高度道路交通システム「ITS：Intelligent Transport Systems」は、先進の通信技術を用いて、道路交通の高度化を図るシステムであり、近年、専用狭域無線通信「DSRC：Dedicated Short Range Communication」や近赤外線通信（光ビーコン）などの通信メディアを活用した路車間通信システムの開発が行われている[1][2][3]。
