Design and algorithm implementation of public traffic transfer model based on weighted directed graph

The bus was the priority travel mode for most citizens in the urban public transportation network. The research of bus transfer and query algorithm, the design of a system that can run on the Android platform and can query bus information promptly and accurately has become a realistic application requirement. In this paper, in terms of the issue of public transport transfer query and transfer, a weighted directed graph was adopted to describe the bus network. The public transport transfer matrix was constructed by a weighted directed graph based on the bus network. According to the actual test, the bus route display, the query of the route and the query of the transfer scheme could be achieved by the designed algorithm, which proved that the algorithm was effective.
