实用小城镇公交线网规划方法研究——以浙江平阳县水头镇为例

Research on Bus-Route Network Planning of Small Town——A Case Study on Shuitou,Pingyang,Zhejiang

以逐条布设、优化成网方法为基础,提出一种改进的小城镇公交线网规划方法,即首先确定出公交线路要求经过的若干重要节点,然后根据公交线网约束条件和直达乘客最大原则,选出若干备选线路的大致走向,最后运用Dijkstra算法寻找这些重要节点之间的最短路径,确定出公交线路的具体走向。该算法充分考虑了小城镇公交出行的特点,简便实用。

An improved method of bus-route network planning is presented on the basis of one by one laid bus route to optimize the whole network,by first establishing a number of important nodes in the bus lines,then select the general direction of several alternative routes according to bus line constraints and the largest quantity of nonstop passengers.Finally determine the bus route by dijkstra algorithm.The method is suitable for small town considering the Characteristics of bus travel.
