中文摘要：
基于北京市典型路口的调查数据,研究信号交叉口自行车骑行者的微观穿越行为。通过录像拍摄获取470个红灯期间到达的非机动车骑行者穿越行为数据。运用交叉列联表的卡方检验和生存分析的非参数估计方法,对电动自行车与人力自行车在信号交叉口的等待时空分布、闯红灯违规率、二次穿越和穿越轨迹等进行定量比较。结果表明电动自行车骑行者具有更短的等待忍耐时间,更高的闯红灯违规率,穿越过程中也表现出更高的风险偏好。牌照管理和限速有利于提高电动自行车的安全性。
英文摘要：
Based on survey data at typical intersections in Beijing, microscopic street-crossing behaviors of bicyclists at signalized intersections are investigated. A total of 470 two-wheeled riders approaching the intersections during red light periods were observed. Chi-square test in crosstab analysis and non-parametric estimation method in survival analysis are used to compare the spatial and temporal distribution of waiting times, rate of red-light violation, twice crossing behavior and crossing trajectory between electric bike riders and common bicyclists at signalized intersections. The results show that electric bike riders have shorter waiting times, larger rates of redlight violation and higher risk preferences in the crossing behavior compared with common bicyclists. License management and speed limitation can effectively enhance the safety of electric bike riders.
