多模式复合交通网络的拓扑一致性处理

Topological Consistency of Multimodal Composite Transportation Network

城市交通已从单一模式向有规则的多模式叠加、复合的交通体系转变,多模式复合交通网络模型较传统的单一模式网络模型增加了模式转换的概念,其网络的拓扑一致性维护也较传统单一模式网络更加复杂.针对多模式与单一模式的差异及复杂性,分析了多模式网络中存在的变化类型,并针对网络要素的3种典型变化情形给出了多模式网络的拓扑关系一致性处理方法.该方法在模拟双模式交通网络中予以实现,能够正确地维护多模式网络的拓扑关系,验证了该方法的正确性.该方法将为多模式网络的拓扑一致性研究提供参考.

City transportation has transformed from single modal to multimodal composite transportation system.Compared with single modal network model,multimodal composite transport network model adds the concept of mode transfer;therefore its topological consistency maintenance is more complex.Aimed at the difference and complexity between single mode and multimode,this paper analyzes the changing types in multimodal network,presents the topological consistency maintenance methods for these typical changing types.Test shows that these methods can correctly maintain the topological relationship of multimodal network.The method presented in the paper provides valuable references for study on topological consistency of multimodal network.
