摘　　要：在BPR路段阻抗函数的基础上,考虑路段上小汽车与常规公交的相互干扰以及常规公交与轨道交通之间流量的相互影响,构造了不同交通方式的路段阻抗函数。引入时间价值这一参数,分析乘客出行的整个交通过程,利用惩罚函数模拟乘客的出行心理,给出了不同交通方式的理解出行成本,然后根据随机效用理论给出了乘客的出行效用,利用Logit模型计算出乘客的方式选择概率。最后,结合重庆实例对城市公共交通的发展提出了一些建议。On the basis of BPR road impedance function,it is considered of the mutual interference within cars and conventional public traffic and the mutual influence between conventional public traffic and rail transit＇s passenger flow to construct the road impedance functions of different traffic modes.Introducing this parameter of time value,analyzing the entire traffic process of passengers and simulating passengers traveling psychology using penalty function,the understanding travel cost of different modes are provided,then the passengers＇ traveling utility is given according to immediately utility theory,and the option probability of passengers traffic mode choice is calculated by using the Logit model.Finally,combined with a case of Chongqing,several suggestions are proposed for the development of urban public transport.
