摘要
衔接多种运输方式之间中转货流的通用型综合交通枢纽是国家综合货物运输网路体系中的重要节点,同时也是城市交通网络的重要组成部分.本文运用无缝中转的思想,从综合交通枢纽与城市交通网络之间的动态关系出发,既保证用户广义费用最低,同时使整个货物运输系统的社会效益最大,从而构建综合交通枢纽货运站布局优化模型.该模型在考虑四种运输方式基础上,加入城市货流作为第五种运输方式,增强了模型的优越性.通过应用遗传算法求解模拟算例,验证了模型的合理性及遗传算法求解该问题的优越性.研究结果表明,该模型与实际情况吻合,是城市综合交通枢纽货运站布局优化的有效方法之一.
The general-purpose integrated transportation hub which links up with multi-modal transport transit cargo flow is not only an important node in the national integrated transportation network system, but also a crucial part of the urban transportation network. The paper uses the ideas of seamless interchange, from the dynamic interactions between comprehensive transportation terminals and urban transportation network, which can ensure both a minimum user generalized cost and a maximum of social benefit in the system. The optimization model is thus proposed to determine the locations of freight stations in integrated transport hub. The model considers four modes of transport, and adds urban flow of goods as the fifth mode of transport, which enhances the model superiority. The genetic algorithm is used to solve the simulation example and the rationality of the model and the advantages are validated. Results show that the model is more consistent with the real conditions and it is one of the effective ways for optimizing the freight stationlocation of the comprehensive transportation terminal.
