In this paper, we introduce a road condition sharing system using Vehicle-to-Vehicle communication in various communication environment. 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 our system. Using our 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.
