The transfer system, an important subsystem in urban citizen passenger transport system, is a guarantee of public transport priority and is crucial in the whole urban passenger transport traffic. What the majority of bus passengers consider is the convenience and comfort of the bus ride, which reduces the transfer time of bus passengers. ＂Transfer time＂ is consid- ered to be the first factor by the majority of bus passengers who select the routes. In this paper, according to the needs of passengers, optimization algorithm, with the minimal distance being the first goal, namely, the improved Dijkstra algorithm based on the minimal distance, is put forward on the basis of the optimization algorithm with the minimal transfer time being the first goal.
