Recently in the world, Technologies using V2I(Vehicle-to-Infrastructure), V2V(Vehicle-to-Vehicle), etc. based on ICT(Information and Communication Technologies) are being developed as a system for driving safety. Those systems are designed to prevent traffic accidents by connecting all things using the internet, such as vehicles to vehicles, vehicles to peoples, vehicles to roads. In Japan, traffic systems using IT(Information Technology) are being developed as ITS(Intelligent Transport Systems). To prevent traffic accidents, autonomous control systems such as CMBS(Collision Mitigation Brake System), LKA(Lane Keeping Assist system), and ACC(Adaptive Cruise Control system) are being put to practical use in the market. However, the development of accident prevention systems for motorcycles with high traffic accident rates and high mortality rates is not active. In this paper, we propose and evaluate an HMI(Human Machine Interface) system that presents visual and auditory information as simple information to prevent traffic accidents by using ITS. This study was carried out on the assumption that the system provides an intuitive notification to the riders for the assistance in decelerating and stopping when their dangerous situations that could not be detected during riding. Therefore, the system should present information at the right time according to the situation. As a research method, we investigated the driving behavior of 30 male subjects in their 20's using a riding simulator applied the accident avoidance supporting system. And it used the scenarios involving scenarios #1 and #2, dummy scenarios, and malfunction scenario. And evaluated the effectiveness of the system through the results of critical parameters and accident probability. As a result, the brake reaction time and average deceleration decreased when using the system, and it is possible to stop the vehicle more safely. We evaluated the system is effective from reduced accident probability when using the system. This system was designed to prevent intersection accidents. Those accidents represent more than 70% of the motorcycle accident rate in Japan.
