摘　　要：论文针对城市交通拥挤不堪和出租车空驶率高的现状,提出了出租车合乘能提高人们选择出租车出行的频次,减少道路拥堵,提高出行效率。论文对出租车合乘进行了概念定义和合乘模式划分,分析了出租车合乘的信息感知、信息传输与信息反馈,建立了出租车合乘信息服务中心。论文划分了合乘类型,并描述了静态和动态的合乘流程图,并建立了出租车数量模型,采用Floyd算法计算整个网络中任意两点间的最短路问题。依据合乘出租车上的乘客数确定不同的合乘状态,在体现收费公平的基础上建立了合乘计费模型,和解决了分级站点合乘组织及生活性合乘问题。Facing the current situation of urban traffic congestion and high unloaded ratio of taxi,this article puts forward that carpool can improve the rate that people choose taxi,reduce road congestion and improve travel efficiency. This article works out the concept definition of carpool and differentiates the carpool modes,classifies the carpool, analyzes the information sense , information transmission and information feedback of carpool,establishes an information service center of carpool,divides carpool type and describes the static and dynamic carpool flow chart. This article sets up a taxi quantity model,uses the algorithm of Floyd to calculate the most short circuit between any two points＆amp;nbsp;in a whole network. The different carpool states was identified based on the number of passengers in a taxi,and a carpool charging model was established on the basis of fair charging. This article solves the problems of carpool organization of the hierarchical sites and carpool for facilitating the life.
