摘要
为了探究影响城市不同空间行人交通事故严重程度的影响因子,以美国北卡罗来纳州的夏洛特市2010~2019年间共计发生的4 230起行人事故为研究对象,根据事故发生地点将其分为交叉口事故和路段事故2类。以行人受伤程度为因变量,选取涉事车型、事发天气等23个因素作为候选自变量,通过共线性分析、预测力检验等筛选其中对不同空间行人交通事故严重程度有明显影响的因素,分别建立起Logistic行人交通事故严重程度分析模型进行对比分析,以探究人、车、路、环境等因素对不同事故地点行人交通事故严重程度的影响。结果表明:不同事故地点的行人交通事故严重程度影响因子之间存在异同性。研究结果可为降低行人交通事故严重程度提供一定参考依据。
In order to explore the impact factors that affect the severity of pedestrian traffic accidents in different urban spaces, a total of 4 230 pedestrian accidents occurred in Charlotte, North Carolina, USA from 2010 to 2019 were studied, according to the accident location, it can be divided into two types: intersection accident and road section accident. Taking the degree of pedestrian injury as dependent variable, 23 factors, such as vehicle type and weather, were selected as candidate independent variables,through colinearity analysis and predictive test, the factors that have obvious influence on the severity of pedestrian traffic accidents in different spaces were screened, and the Logistic pedestrian traffic accident severity analysis model was established for comparative analysis, in order to explore the impact of people, vehicles, roads, environment and other factors on the severity of pedestrian traffic accidents at different accident locations. The results show that there are similarities and differences among the influencing factors of pedestrian traffic accident severity in different accident locations. The results can provide some reference for reducing the severity of pedestrian traffic accidents.
