Impact of the latency in vehicular networks: Analysis on the reaction distance

Vehicular networks are expected to contribute to improving transportation systems, especially reducing traffic accidents. However, the impact of vehicular networks may not be easy to intuitionally realize because it is difficult to express in numerical value. To address this issue, we analyze the effectiveness of the latency in vehicular networks in numerical form using the concept of the reaction distance in this paper. Furthermore, we compare the performance of vehicular networks with regard to the types of communications.
