Abstract: To solve the problem of reminder services in the public transport system without the real-time data of city bus, this paper, puts forward the solution which integrates open source bus routes data with the mobile sensing data. Firstly, the optimal bus site automatic generation algorithm base of Haversine formula, and the bus site monitoring and alert algorithm based on heartbeat mechanism are designed. Secondly, by optimizing the distance formula, geographical distance calculation time complexity is reduced, therefore, the performance of the algorithm is enhanced. Finally, the intelligent public transport APP is implemented by using mobile cross platform APPCan.
