基于多方式选择的区域停车换乘设施选址研究

Study on the Regional Location Choice of Park and Ride Facility Based on Multiple Modes Choice

当区域内停车换乘设施布设过于密集时，易造成相邻设施点互相竞争、资源浪费，甚至引发出行效率下降，而既往的研究通常重视换乘需求最大化，忽略了这一现象对选址的影响。文中通过建立嘉定城区的模拟路网，对多种出行方式定义效用函数，运用MATLAB程序进行静态交通分配仿真。得到在不同位置设置换乘设施情况下，出行者选择停车换乘的比例和平均单位距离出行时间。结果表明，停车换乘设施的服务半径为2～5km；当区域内换乘设施由2个增加为3个时，平均单位距离出行时间反而增加约8％。

A discussion is provided on P＆R location optimizations on a regional level, for which influ- ences among adiacent facilities are important to be considered, however mostly neglected. By establis- hing a road network which simulates Jiading new city, defining different travel modes＂ utility functions and using MATLAB to simulate the static traffic assignment, the travelers＇ proportion choosing park- and-ride mode and the corresponding average travel time per distance in cases of locating park-and- rides in different places are obtained. It turns out that a P＆R facility＇s service area is within a radius of 2-Skm; there is an average travel time per distance increase of 8 percent when increasing the P＆R sites＇ number from 2 to 3.
