Abstract

自転車関連の交通事故の割合は増加しており,自転車と自動車の出合い頭事故は自転車関連事故の5割を占めている.特に,幹線道路小交差点における出会い頭事故では,自歩道で車道の車両とは逆方向に走行している自転車の危険性が指摘されている.本研究では,ドライビングシミュレータを用いた仮想実験を用いて,見通しが異なる幹線道路小交差点を対象に,細街路から幹線道路に合流する自動車と幹線道路を通行する自転車の出会い頭状況を再現し,自転車の走行方向・草稿位置が異なる場合のドライバー挙動を計測した.ドライバーの注視挙動,及びTTC等の安全性指標を分析した結果,自動車は左側見通しが悪くなると注視しなくなり,歩道寄りを走行する自転車,逆走する自転車は,他の位置・方向の自転車よりも危険性が高くなることが明らかになった.

Bicycle accidents increased in recent years in the ratio of the total number of traffic accidents. 50% of the accidents are crossing collision between bicycles and vehicles at unsignalized small junctions. Especialy, danger at small junctions along the arterial street has been focused where cyclings of both directions are permitted on the sidewalks in Japan. It is said that bicycles traveling in opposite direction to cars along the sidewalks near the buildings are dangerous.<br>This study aims at analysis on behavior of the car drivers who goes out from side roads into a arterial streets. we used virtual experiments by driving simulator and measured indecis such as position of driver's attention, TTC etc to evaluate the safety from the visibility of coners, cycling direction and positions. It was found that car drivers have tendency to pay attention only to the right side where car comes from, but not to the left side when the visibility of left side is bad,. Bicycles which cycling on sidewalk, and cycling on opposite direction to cars are more dangerours than cycling on other positions or directions.
