To What Extent does the no Right Turn Regulation Increase Travelling Distance

移動距離に着目した右折禁止交通の効率性

Autonomous vehicles will be used in public roads in the near future. However, it seems difficult for autonomous vehicles to turn right within urban areas. In addition, there are many traffic accidents when the right turn is made. The right turn regulation may be useful, but it reduces the efficiency of traveling. The aim of this paper is to analyze how much the no right turn regulation increases the average travel distances between the origin and destination points where they are uniformly and independently distributed along the grid streets. The authors compare the results with the average distance traveled.人工知能や各種センサーの進歩により，公道における自動運転による自動車の走行が現実味を帯びてきた．しかし，自動運転は都市部における右折で課題が多いとされる．右折時には，対向車や反対車線を走る車，横断歩道を渡る歩行者への注意が必要となるからである．また，自動運転に限らず通常の運転でも右折時には事故が起きやすい．以上より，右折を禁止した交通は有用と考えられるが，右折禁止は交通トリップの距離を増大させることは明らかである．本研究では，格子状の道路網において，街区に沿ってトリップの起点と終点が独立かつ一様に分布する状況を想定し，右折禁止の場合と現状とを比較した．道路網内の単位トリップ当たりの平均距離の解析表示を導出することで，右折禁止交通による道路網内の平均距離がどの程度伸びるかを解析的に示した．
