| Abstract |
今後老朽化の進む高速道路の点検や補修のための工事によって各所で車線規制による渋滞の頻発が予想される．このときの交通状況を改善する合流方法として交互合流法がある．工事車線規制渋滞時の交互合流を定着させるためには, ドライバーに交互合流に関する適切な情報を提供して心理的負荷を軽減し，交互合流への協力意識を向上させる必要がある．そこで本研究では，交互合流に関する情報を道路標識で提供するドライビングシミュ...レータを作成し，情報内容の違いによるドライバーの心理や合流区間での運転挙動の変化を分析した．その結果，ドライバーが走行する車線やその隣接車線でのとるべき行動を道路上で教示することで，ドライバーの心理的負荷を軽減し，交互合流への協力意識を向上させ，さらにより安全でスムーズな合流行動を促進し得るという結果を得た．
The frequent traffic congestions will occur due to the lane restrictions for the reconstruction works in the aging expressways. The zipper merging was proposed at this occasion as merging method to improve traffic condition. In order to establish zipper merging at the lane regulation, it is necessary to provide drivers with appropriate information on zipper merging to reduce the mental load and to improve their awareness of cooperation with zipper merging. In this study, we created a driving simulator that reproduce zipper merging with road signs, and verified changes in the mental and behavior of the drivers in the merging section based on the information content. We obtained the result that the mental load on the drivers was reduced and the cooperation for zipper merging was improved and that zipper merging was expected to be safer and smoother by teaching the actions that should be taken in the driving lane and the actions that would be taken by the drivers in the adjacent lane.show more
