Description
日本では交差点での自転車事故の割合が高く,他国にない交差部での自転車の双方向通行がその要因として着目されている.このため,自転車の左側通行を誘導する自転車専用通行帯や自転車走行指導帯の整備が進められている.本研究では,金沢市の細街路型自転車走行指導帯での安全性向上効果を確認するため,交差点における自転車の進入挙動に着目した.具体的には,5 箇所の交差点において走行指導帯整備前後のビデオをもとに,自転車の進入挙動,自動車速度の変化を分析するとともに,指導帯有無・交通事故発生状況の異なる 3 箇所の交差点で自転車の挙動について比較した.その結果,細街路における自転車通行指導帯整備による左側通行の遵守向上によって,危険とされる逆走方向から交差点に進入する自転車の割合が減少していることが明らかになった.
Description Alternative
The ratio of bicycles accidents at junctions in Japan is quite high. Both-way running of bicycles at junctions, which is unique system in the world, is focused on as a reason of this phenomenon. Bicycle lanes, which promote bicycles running on left side of the carriageway, have been introduced to solve this problem by realizing one-way bicycles running system. In this study, in order to confirm the effects on safety by bicycle lane system on residential streets in Kanazawa city, the approaching behavior of bicycles is focused on. Bicycles’ behavior and vehicles’ speed before and after the implementation of bicycle lanes at five junctions using video survey are analyzed, and bicycles’ behavior at three junctions with different accident records and condition of bicycle lanes is compared. As results, the ratio of wrong way approaching of bicycles is decreased by the implementation or existence of bicycle lane system which promotes keep left running of bicycles on the approach streets.
