Abstract

Pedestrian safety is essential to realize a walkable city. This study analyzed the impact of road infrastructure and traffic control on severity of pedestrian–vehicle crashes at intersections and non-intersections. We applied a bias-reduced logistic regression analysis using 86,406 pedestrian–vehicle crashes data including 2636 fatal accidents in Japan. The results of the study indicate that medians increased the severity of crashes at intersections; on the other hand, they decreased the severity at non-intersections. In addition, flashing traffic signals increase the severity while stop signs decrease the severity at intersections.

道路基础设施和交通控制对交叉口和非交叉口行人-车辆碰撞严重程度的影响分析——使用偏倚减少逻辑回归

行人安全是实现步行城市的关键。本研究分析了道路基础设施和交通管制对十字路口和非十字路口行人与车辆碰撞严重程度的影响。我们对日本86,406起行人与车辆碰撞数据进行了减少偏差的逻辑回归分析，其中包括2636起致命事故。研究结果表明，中位数增加了交叉口碰撞的严重程度;另一方面，他们降低了非十字路口的严重程度。此外，在十字路口，闪烁的交通信号增加了严重程度，而停止标志降低了严重程度。

期刊介绍： First published in 1977 as an international journal sponsored by the International Association of Traffic and Safety Sciences, IATSS Research has contributed to the dissemination of interdisciplinary wisdom on ideal mobility, particularly in Asia. IATSS Research is an international refereed journal providing a platform for the exchange of scientific findings on transportation and safety across a wide range of academic fields, with particular emphasis on the links between scientific findings and practice in society and cultural contexts. IATSS Research welcomes submission of original research articles and reviews that satisfy the following conditions: 1.Relevant to transportation and safety, and the multiple impacts of transportation systems on security, human health, and the environment. 2.Contains important policy and practical implications based on scientific evidence in the applicable academic field. In addition to welcoming general submissions, IATSS Research occasionally plans and publishes special feature sections and special issues composed of invited articles addressing specific topics.
