摘　　要：出租车在繁荣城市经济、方便居民生活等方面起到积极作用的同时也给城市交通带来一些负面影响.本文以出租车在城市道路上的跟驰行为为研究对象,分析其行为特点及安全性.实际调查数据显示,在相同的道路交通条件下,出租车跟驰间距普遍小于其他车辆.选取速度、距离为主要变量,建立跟驰安全约束条件.结合实例,分析出租车小间距跟驰行为的安全性.结果表明,出租车小间距跟驰明显降低其行驶安全性,增加了事故发生的机率.Providing flexible and convenient services,taxi becomes one of the most important modes of passenger transport in many major cities of China.However,the increasingly popular taxis have brought several problems to urban traffic.This study explores the characteristics and safety of the following behaviors of taxis on urban road.It is observed that taxis run with smaller following spaces than the ones between public vehicles of other types.Furthermore,the safety of following behaviors of taxis is examined in a quantificational manner with the proposed models.In terms of the numerical examples,the risk-taking following behavior increases the possibility of crashes.The variable of following space can be selected as a predictor of accidents.
