摘要
同时考虑社会利益和个人利益,选取公交系统(包括常规公交和出租车)出行者占用道路总面积、广义出行费用、拥挤度为指标建立多目标函数模型,求得出租车出行占公交系统出行的比例,根据公交系统出行总比例最终确定全方式出行结构中出租车出行方式分担率.实例分析证明该方法所需数据量少、可操作性强,宏观政策及其微观影响在预测过程中互为反馈,该方法既可用于确定出租车出行方式分担率,又可为交通政策决策者提供理论依据.
Considering both social and individual behalf, a multiple objective function model is developed, based on the area of the occupied road, travel cost and congestion degree of travelers chasing public traffic. The scale between taxi traffic mode and the public traffic mode is figured out from the model, which is used to calculate the taxi traffic mode split rate in the full-mode traffic structure. The results indicate that the method is simple and conve- nient： macroscopic policy and its microcosmic influence are interacted, It not only can forecast the taxi traffic mode split rate, but can provide theoretic support for the traffic policy decision-maker.
