Abstract

本研究では,千葉県東葛地域を対象として,通行方法別に分類した自転車の遭遇台数調査のデータと自動車と自転車間で発生した事故の統計データを用い,自転車の通行方法別に事故率の比較を行った.その結果,進行サイドでの比較では,車道における自転車の右側通行の危険性は左側通行の2.8倍高くなった.歩道においても同様に自転車の右側通行の危険性は左側通行の2.7倍高いという結果になった.また,通行位置による比較では,自転車の歩道走行(左側通行・右側通行)と比較した車道走行(左側通行)の危険性は3.0倍となり,車道走行の危険性が高くなっていた.以上により,自転車に通行方法を遵守させるためにも,より安全な自転車の車道走行環境を形成していく必要性が示唆された.

This study considered the risk of traffic accident occurrence depending on the different bicycle's traffic pattern: right- and left-hand traffic, roadway with cars and sidewalk with pedestrian. The data of the traffic volume and traffic accident in Chiba Toukatsu area were used for reference. The study results showed the rates of bicycle accident were varied with bicycle's traffic pattern. For example, traveling bicycle in roadway with right-hand traffic had 2.8 times higher accidents than traveling bicycle in roadway with left-hand. Also the results showed traveling bicycle on sidewalk with right-hand traffic had 2.7 times higher accidents than traveling bicycle on sidewalk with left-hand. And the rate of accidents when bicycles use roadway traffic was 3.0 times higher than when use sidewalk. Under the present traffic law, the analysis of the above rates suggested that better environment should be prepared for more safe roadway for bicycles.
