基于集散点选择模型的城市地下快速路网规划研究

城市地下快速路成为缓解城市交通问题的一个新的有效途径，正逐渐受到重视，合理规划地下快速路网是当前的重要问题。本文针对地下快速路服务中长距离出行车辆的功能定位、特性和布局原则，按照点线面依次规划的程序，建立地下快速路集散点选择模型，提出从常规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规划流程，最后给出案例分析结果，证明所提出的规划流程以及集散点选择模型具有一定的理论和应用价值。

Study on Urban Underground Expressway Planning Based on Depot Choice Model

Urban underground expressway was a new available way to solve the urban traffic problem, and how to plan underground expressway was an important problem. This paper brought forward a point-line-net plan way base on the function for serving middle and long-distance cars, the characteristic and the plan principia. This paper found the underground expressway depot choice model, and brought forward the plan way containing processing convention OD survey data, choicing depot, switching OD matrix, drawwing depot expectation figure, and corresponded planning the underground expressway. At last, the paper put forward a case analysis, and the result indicated that the plan way and model have theoretical and applied value.
