多层次公交线网拓扑结构分析

为构建与城市道路等级相类似的分级(层)公交线路,明确不同线路的主体功能,有序而科学的引导乘客的出行行为和习惯,减轻地面道路交通压力的同时创建一个优良的公共交通服务体系,根据城市布局结构和路网架构特征,参考一般的公交线网结构,构建适应多层次公交特点、分别适用于单中心、多中心、分离式组团和带状等4类城市用地布局的公交网络拓扑结构,并提出了串联、并联、叉联和枝联等4种线路连接方式。研究结果可用于指导不同用地布局城市多层次公交线网架构,并为进一步深入研究多层次公交线网的规划设计打下基础。

Analysis on Topology Frame of Multi-level Transit System Network

In order to construct a multi-level transit system similar to the urban road classification,ensure each route's main function,lead orderly and scientific travel behaviors and habits,relieve traffic pressure on the ground so as to create a gcod transit service system,based on the features of urban space structure and road network structure,referring to general transit network structure,four kinds of transit network topology frame adapting to multilevel transit characteristics and suitable for single center,multi-center,separate organized groups and banded urban land layout were built.Four kinds of link connections including serial connection,parallel connection,fork joint and branch joint were put forward.The presented topology frames and connection modes can be used to guide muhi-level transit network design for different urban land use purposes and hy the foundation of the planning of multi-level transit system network.
