综合客运枢纽旅客全过程流线优化模型

摘要

With the passengers' diversified travel demands and requirements for high-level services for hub stations, the reasonable streamline deign for passengers' transfers among different transportation modes become one of the key issues of integrated transportation hubs planning and management. This paper introduces the concept of streamline design for the whole process of passenger transfer which expands (he research scope of passage flow optimization. The optimization procedure is regarded as a graph theory problem by abstracting the hub into a mxn-dimensioned stereo space connected graph. Then, it classifies the nodes into several partial nodes with directions. Base on these, the optimization model is formulated. Finally, the example of a hub station is used to illustrate the incremental assignment method and verifies the feasibility and effectiveness of the model%随着旅客出行需求日益多样化,旅客对枢纽站服务水平的要求逐渐提高,多种交通方式之间旅客合理换乘流线设计成为综合交通枢纽客流组织的关键问题之一.针对这一问题,引入全过程流线的概念,扩大枢纽流线优化的研究范围,将枢纽抽象为m×n的立体空间连通图,使得枢纽流线优化问题转化为图论问题.在对各节点进行二次拆分,优化节点费用的基础上,构造了旅客全过程流线优化模型.最后,选用某综合枢纽站作为研究对象,采用增量配流法进行计算,得到该枢纽站的流线优化方案,验证了模型的可行性与有效性.
