[Machine translation by Google Translate]
The characteristics of traffic accidents vary depending on the region, and almost the same prefectures usually occupy the top position in the number of injured people and fatalities. When explaining the factors of such regional differences, for example, the mode of transportation share, outing rate, aging rate, driving characteristics, etc. are mentioned. On the other hand, according to Levin's law of behavior, human behavior is related to human characteristics and environment. Considering this, it is possible to hypothesize that the environment of the site where the traffic accident occurs, that is, the characteristics of roads and intersections also have regional characteristics, and that they influence the traffic accident. In this report, we focus on regional differences in the structure of roads and intersections on ordinary roads, and introduce examples of analysis of their actual conditions and their impact on traffic accidents.
[Original Japanese summary]
交通事故特性には地域性があり，例年ほぼ同じ県が交通事故負傷者数や死亡者数ランキングの上位を占める．このような地域差の要因を説明する際，例えば交通手段分担率や外出率，高齢化率，運転特性などが挙げられる．一方，レヴィンの行動の法則によると，人間の行動には人間特性と環境の2つが関係しているとされる．このことを勘案すると，交通事故が発生する現場の環境，すなわち道路や交差点の特性も地域性をもち，かつ，交通事故に影響を及ぼす，との仮説も考えられる．本報告では一般道の道路・交差点構造の地域差に着目し，その実態や交通事故への影響を分析した事例を紹介する
