In Japan, local government patrols their roads to maintain effectively and to collect the road condition. However, it is difficult to operate and maintain the road continuously by a lack of engineering staff and progression of road aging and deterioration. It is necessary to find the damage points efficiently. Therefore, in this research, to improve the efficiency of road patrols by local governments, we installed acceleration, global navigation satellite system (GNSS), and camera sensor devices on home delivery company vehicles that regularly use targeted roads. We devised technologies for efficiently collecting road data from these sensors and for identifying road damage sites by analyzing these data. In future studies, we plan to improve efficiency by using system for automatic extraction of road damage images and location information from acceleration data.
