摘　　要：针对城市公共交通系统的行车时间和行车间隙易受影响的特点,以整个公交出行链为落脚点,从出行者的角度对公交的运行时间和乘客的在站等车时间进行了研究,建立了公交的运行时间可靠度、等候时间可靠度模型.以北京市为例,对晚高峰的公交时间可靠度进行了计算和分析.结果表明北京市的公交时间可靠度为中等水平.The travel time and interval of vehicles are easy to be affected in urban public transport system. Even though the scheduled frequencies are fixed, actual arriving frequencies of buses may still have big changes. Based on trip chain of public transit, the paper researc waiting time that passengers spend on stops. reliability of transit have been established. transit at rush hours has been calculated and transit is in medium level. The models of traveling hes traveling time of buses and time reliability and waiting time Finally, taking Beijing for example, time reliability of analyzed. The result presents time reliability of Beijing
