基于集散点选择模型的地下快速路网规划

Underground Expressway Network Planning Based on Depot Choice Model

针对地下快速路服务于中长距离出行车辆的功能定位、特性和布局原则,建立了地下快速路集散点选择模型,提出了从常规OD调查数据处理到集散点选择、再利用OD表转换和基于集散点的期望线图、最终协调规划地下快速路网的点线面依次规划流程,并结合案例进行了分析和验证.结果表明:文中提出的规划流程以及所建立的集散点选择模型对合理规划地下快速路网有理论和应用价值.

According to the characteristics, planning principle and function orientation of the underground express- way serving middle- and long-distance transfers, this paper presents a depot choice model of underground express- way, and brings forward a point-line-surface planning way containing the processing of conventional 0D survey da- ta, the depot choice, the switching of OD table, the drawing of depot expectation figure and the coordinated plan- ning of the underground expressway. A case analysis is then performed. The results show that both the planning way and the depot choice model are theoretically valuable and practicably viable for the reasonable planning of un- derground expressway network.
