Development and Evaluation of Hazardous Location Identification and Safe Route Recommendation System for Bicycles based on Various Motion Analysis

Abstract (in Japanese) (See Japanese page) 
(in English) In recent years, the number of bicyclists has increased in Japan due to various reasons such as improvement of health awareness and consideration for the natural environment. On the other hand, the number of bicycle-related accidents is decreasing year by year, but the ratio of the accidents is still high (around 20% of all traffic accidents). Here, the improvement of the bicycle traffic space has a certain effect on the reduction of the bicycle-related accidents, but it is not realistic to maintain the bicycle traffic space for all general roads. Therefore, in order to secure the driving of bicycles on general roads, this study proposes a new identification system of hazardous location where the safe driving of the bicycle may be hindered. The proposed system detects the hazardous locations where there are steps on the road and many sudden braking / steering wheels occur during the driving by collecting and analyzing measurement data using acceleration sensors and gyro sensors installed on the bicycle. Furthermore, the proposed system has a function of route recommendation based on the detection results of the hazardous locations. This function can recommend not only the shortest route to the destination but also the safe route where the number of hazardous locations is comparably few among the routes.
