| 摘 要： | 为探究提前右转车道处不同因素与人车冲突的相关性，以及行人空间违章对过街安全的影响。采集2 062个行人及人车冲突的样本数据，获取行人和机动车的时空信息，对比分析不同类型行人过街轨迹的特征；综合考虑人车冲突时间和速度指标构建人车冲突严重度指标，从行人生理特征、车流条件、道路环境等方面选取8个因素作为自变量，构建人车冲突严重度的多元有序Logistic模型。研究结果表明：空间违章过街的行人平均过街速度和速度离散程度都明显高于其他行人；年龄、车速、人行横道长度、车辆到达率以及过街轨迹类型都是影响人车冲突严重程度的重要因素。各类型空间违章行为使严重冲突占比均提升75%以上。研究结果有助于交管部门采取措施保障行人过街安全。

| Abstract: | In order to investigate the correlation between different factors at the advance right-turn lane and pedestrian-vehicle conflict,and the influence of pedestrian spatial violation on crossing safety,2 062 sample data of pedestrian and pedestrian-vehicle conflict were collected,then the spatial and temporal information of pedestrian and vehicle were obtained,and the characteristics of different types of pedestrian crossing trajectory were compared and analyzed.Comprehensively considering the pedestrian-vehicle conflict time and speed indexes,the severity index of pedestrian-vehicle conflict was constructed,and taking eight factors from the aspects of physiological characteristics of pedestrian,traffic conditions and road environment as the independent variables,a multivariate ordered Logistic model of pedestrian-vehicle conflict severity was constructed.The results showed that both the average crossing speed and speed dispersion degree of pedestrian with spatial crossing violation were significantly higher than those of other pedestrian.Age,speed,number of lanes,vehicle arrival rate,and type of crossing trajectory were all important factors affecting the severity of pedestrian-vehicle conflict.All types of spatial violation behavior raised the percentage of serious conflict by more than 75%.The results help traffic control authorities to take measures to ensure the pedestrian crossing safety. |
