The invention discloses a pedestrian street-crossing efficiency and safety analysis method based on a symmetric intersection. The pedestrian street-crossing efficiency and safety analysis method comprises the following steps of: S1, establishing a street crossing model; S101, a mode 1: a conventional mode; S102, a mode 2: a two-stage street crossing mode; S103, a mode 3: a mutual exclusion phase mode; S2, efficiency analysis: taking the delay as an efficiency index, and establishing straight street crossing delay analysis and diagonal street crossing delay pedestrian delay models for the threestreet crossing modes; S201: mode 1; S202: mode 2; S203, mode 3; S204, integrating the delay models; S3, safety analysis: calculating the number of potential traffic accidents based on pedestrian andvehicle exposure conflicts; S4, comprehensive analysis: converting the delay and the potential safety accident into money, and taking the total cost as a comprehensive index for evaluating the performance of pedestrian street crossing in different modes; S5, performing comparative analysis; and S6, sensitivity analysis: researching variables influencing the total cost. The method is beneficial tohandling conflicts between pedestrians and vehicles at the intersection.
本发明公开了一种基于对称交叉口的行人过街效率与安全分析方法,包括如下步骤:S1、建立过街模型;S101、模式1:常规模式;S102、模式2:两阶段过街模式;S103、模式3:互斥相位模式;S2、效率分析:将延误作为效率指标,建立对于三种过街模式的直行过街延误分析和对角过街延误行人延误模型;S201:模式1;S202:模式2;S203:模式3;S204:延误模型的整合;S3、安全分析:基于行人与车辆暴露冲突计算潜在的交通事故数量;S4、综合分析:将延误和潜在的安全事故分别转换为金钱,并利用总成本作为评估行人过街不同模式下性能的综合指标;S5、比较分析;S6、敏感性分析:研究影响总成本的变量。该方法有利于处理十字交叉口行人与车辆之间的冲突。
