A Road Alert Information Sharing System with Multiple Vehicles Using Vehicle-to-Vehicle Communication Considering Various Communication Network Environment

In this paper, we introduce a road alert information sharing system with multiple vehicles using Vehicle-to-Vehicle communication considering various communication network environment, which is named SODiCS (Spatial and temporal Omnidirectional sensor data Distribution and Collection System). Japan is prone to natural disasters. In addition, traffic hazards and traffic accidents occur due to snow. A wide range and quick condition understanding and monitoring are needed. In addition, it is important to understand the condition of the destination and the road condition to the destination. But, especially after a disaster has occurred, areas that mass media can provide disaster condition information are limited. Recently, various higher technologies have been developed and noticed. By using those technologies, we develop SODiCS. Using this system, we can realize road condition understanding, monitoring and recording as an alert information using multiple sensor data, information sharing between each vehicles and information is provided as web application. As a quantitative evaluation, we measure vehicle-to-vehicle communication quality.
