信号交叉口行人与自行车的等待忍耐行为分析

为了探究行人与自行车骑行者信号交叉口穿越行为的差异，本文运用生存分析方法比较了行人与自行车等待忍耐时间分布及其等待行为影响因素的异同。选取北京典型交叉口通过视频获取了1 595个行为数据，运用生存分析的乘积极限法和Cox比例风险模型分别比较了行人与自行车的等待忍耐时间分布差异以及等待行为的影响因素差异。结果表明整体上行人与自行车的等待忍耐时间分布无显著差异，但等待行为的影响因素及其影响程度上存在一定差异。自行车对等待位置和到达时正在违规的人数反应更敏感，行人对到达时正在等待的人数和机动车流量的反应更敏感。

Analysis of waiting endurance behavior for pedestrians and bicyclists at signal intersections

We compared the difference of waiting endurance time distribution and its influential factors for pedestrians and bicyclists with survivor analysis methods to explore the distinction between crossing behavior of pedestrians and bicyclists at signal intersections. We obtained 1595 behavior data of pedestrians and bicyclists by coding videos at Beijing seven typical signal intersections. We further employed product limit method and Cox proportional hazard model to compare the difference of waiting endurance time distribution and that of influential factors of waiting behavior of pedestrians and bicyclists. Results indicate that no significant difference exists in their waiting time distributions. However, some significant differences exist in the influential factors of their waiting endurance behavior and influential extent. Bicyclists are more sensitive to waiting positions and traffic law violator numbers upon their arrival, while pedestrians are more sensitive to waiting people numbers and vehicle volume upon their arrival.
