Roadside-to-vehicle and vehicle-to-vehicle communication systems have been proposed as part of ITS development to help achieve vehicle safety and realize more secure road traffic environments. In this article we first introduce several typical applications and their radio range requirements for vehicle safety communication systems to clarify the technical point of view. Then we show some field experiment...
High reliability and low latency are crucial requirements for vehicular safety applications. We have previously proposed a media access control (MAC) protocol for a roadside-to-vehicle communication (RVC) system using narrow antenna beam switching with multiple antenna beams to increase reliability even in a shadowing region. In this paper, we describe transmission performance evaluation of an RVC...
