Abstract

本研究の目的は,普通自転車専用通行帯や自転車走行指導帯といった自転車レーンにおける自転車の利用実態を,昼間だけでなく夜間の自転車利用にも着目して明らかにすることである.交通量調査より,同一路線内でも整備状態の異なる箇所では自転車の通行位置割合が異なり,夜間には歩道や車道の整備状態によらず歩道通行の割合が10%程度増加することがわかった.アンケート調査より,昼間に比べ夜間の通行時に車や歩行者の交通量の減少,路面の色等の視認性低下を感じているが,通行位置選択では昼夜問わず,路面の「なめらかさ」や「車の交通量」「車との距離」を重視することがわかった.昼間は車道で夜間は歩道を通行する自転車利用者は,車からの視認性等の安全性を重視しており夜間には車と距離をとることができる歩道を通行することが推察された.

The purpose of this study is to clarify how cyclists behavior and consider the on-street bicycle lane in day and night time where the sidewalk are also permitted to ride by bicycles. From the observation survey, it is indicated that the share of using bicycle lane is changed among different roadway structure like road surface condition, and the share of using sidewalk by bicycle is increased by about 10% in average. From the questionnaire survey , it is indicated that cyclists feel the deterioration of visibility of roadway surface color and traffic signs at night. However, those changes have not affected cyclists' behavioral change such as shifting to the sidewalk from the on-street bicycle lane , because they might rather care their visibility from cars and tend to keep larger distance from cars by riding in sidewalk.
