Abstract

This paper describes a proposal of the multi-hop communication scheme using heavy vehicles in the multi-class zone ITS communication scheme and its performance evaluation. The proposed scheme improves the communication performance by introducing the repeating technique of the synchronization signal and frame control signal using heavy vehicles and multi-hop communication technique of the first and second category intersection RVC (Road to Vehicle Communications) using heavy vehicles to the vehicle that cannot perform RVC owing to shadowing by heavy vehicles. Performance evaluations are carried out by a microscopic traffic flow simulator including the communications, and improvement of communication performances by introduction of the proposed scheme are shown. In addition, it is shown that the required frequency bandwidth achieving 90% of packet arrival rate is 38.2MHz, and the required frequency bandwidth achieving 97% of packet arrival rate is 41.6MHz with the main roadway consists of five lanes and the intersecting roadway consists of three lanes.
