摘要
综合客运枢纽是实现城市各种交通方式间无缝隙换乘的关键节点,决定着整个城市客运系统的运输效率。针对综合客运枢纽通道设计中存在的量化依据不足及交通方式协调问题,结合枢纽自身特性,从成本角度考虑系统最优,建立了固定换乘需求和弹性换乘需求两种情形下,基于系统最优的综合客运枢纽动态、静态配流模型,并设计了应用实例,应用遗传算法加以求解,从而为综合客运枢纽的优化设计提供量化依据。
Passenger terminal is the critical node to achieve seamless transfer among different modes of transport,determining the efficiency of the city′s passenger transport system.Aiming at the lack of quantitative basis for passenger terminal design and transport coordination problems,combined with characteristics of passenger terminal,the system optimization-based static and dynamic flow assignment model of passenger terminal under fixed and elastic conditions is set up from the cost perspective to realize system optimization.Then the model is applied to an example,and is solved by genetic algorithm,thus it can provide quantitative basis for optimized design of passenger terminal.
