Abstract
Recently, several transport policies for bicycles are introduced such as construction of bicycle lane on roadway and one-way operation for bicycle traffic. It is considered that the traffic accident probability of bicycles which run right side of road is larger than those which run left side of road. However, it is based on the traffic accident probability on each intersection, and it is not based on the traffic accident probability between origin and destination for bicycle users. In this research, the traffic accident probability of bicycles by running position and direction considering the number of road crossings between origin and destination for bicycle users is estimated.
