| 摘 要： | 针对Dijkstra算法在公交乘换应用领域存在计算量大、实时性不高、网络负载压力大、滞留时间长且乘换不经济等缺陷,基于WebGIS技术提出一种改进型智能公交乘换模型,将乘换次数和乘车前后总站数优先考虑,从而构造出中转站及其线路对应的路线-站点换乘矩阵,获得最优公交换乘线路。

| Abstract: | The application of Dijkstra algorithm and its advanced version in electronic map in solving the shortest route problem was examined.Disadvantages of the algorithm in dealing with the intelligent interchange of the public transportation area were studied,such as computation complexity,lack of real time,heavy-loaded network,prolonged detention time and uneconomic transtation.An improved model which priotizes the number of transtation and the total number of stops was pre-sented.The optimal transferred route of the public transportation system was obtained.A line-station transfer matrix including transit station and its routes corresponding to the optimal route was derived. |
