摘要
采用生存分析法对行人过街等待过程进行建模，针对长沙市某路段行人过街等待时间调查数据，计算了老年人、中年人、青年人、少年人4组人群的过街等待时间生存曲线，以及不考虑年龄影响因素的整个人群的过街等待时间生存曲线，针对所研究路段得出了行人过街最大等待时间为40～50S的结论。
This paper applied survival analysis to modeling the maximum wait time for pedestrian. The authors collected waiting time of pedestrian for one road section of Changsha City, and calculated survival curve of the elders, the middle-age, the youth, and the children, respectively. A survival curve involving all the age groups was also developed. For the studied road section, the authors come to the conclusion that the maximum waiting time for pedestrian crossing is between 40 seconds and 50 seconds.
