Abstract

本研究では,出発地・目的地間の自転車の車道横断回数を考慮して,自転車の通行方向を左側のみの一方向通行とする整備や規制をおこなった場合と,双方向通行とする整備をおこなった場合との,出発地・目的地間の交通事故遭遇確率の比較をおこなう.具体的には,格子状の道路ネットワークをもつ京都市中心部と,非格子状の道路ネットワークをもつ京都市郊外の洛西ニュータウン付近とを対象として,出発地・目的地間の交通事故遭遇確率の算定をおこない,格子状,非格子状といった道路ネットワーク形状に関する特性と,自転車の通行位置と通行方向による交通事故遭遇確率との関係について比較をおこなう.

 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.
