摘要：

Hokkaido has more traffic fatalities than any other prefecture in Japan. It is an urgent task to reduce these accidents by performing analyses and taking appropriate countermeasures. The Civil Engineering Research Institute of Hokkaido has developed a traffic accident analysis system that uses a GIS. The system links great volumes of traffic accident data accumulated for more than ten years with digital map data indicating accident locations. We added information on the following: road structure, road accessory facilities, and weather information. This system enabled us to extract accident data by road section and by specific condition. The system also allowed us to analyze accident frequency, accident rate, and fatality rate. In winter there are some days when the number of accidents jumps because of weather conditions. We analyzed the data of snowfall, temperature and accident rate, and added a function that predicts the accident rate using weather forecast information.
