说明：  换乘次数最少是乘客出行时考虑的首要因素,描述了传 统的Dijkstra 算法,并分析了Dijkstra 算法不适合公交网络最
(The least number of times of transfer is the most important factor to consider when passengers travel. This paper describes the Dijkstra algorithm of transmission system, and analyzes that Dijkstra algorithm is not suitable for public transport network.)
