1. A summary of the research status of the problems involved in this topic at home and abroad.

With the increasing density of urban construction, it is more and more urgent for people to obtain urban public transport routes through mobile phones. Therefore, if a public transportation inquiry system is designed and implemented, the utilization rate among people should be very high. City bus query interface. Users can query bus routes in three ways, namely, input the starting station and terminal station, input the line number and the name of the station they want to go to. Query results interface. Users will automatically jump to the query result interface after entering requirements. The interface will display the route information, trip information, return information and ride information of the secondary route.

At present, many public transportation query softwares have been developed at home and abroad, such as Aibang Bus, Baidu Map, Google Map and Pocket Bus. , which provides people with the functions of bus route search, station name query, route planning and so on, and brings some convenience to people's travel. However, at present, the function of bus inquiry system is mainly based on static data inquiry, which often cannot reflect real-time traffic conditions; The query function is not intelligent and the operation is inconvenient; Humanization is not well considered, which is not suitable for many people, such as the elderly and people with poor computer skills. The imperfection of these functions hinders the wide use of mobile phone bus inquiry system.

At present, the handheld bus website in Xiamen can query the real-time location information and the distance from the bus stop anytime and anywhere. If citizens want to provide more route choices for their own travel, they can also query the real-time location information of any bus passing through their own site through site query. After the operation of Suzhou Intelligent Bus System, citizens can query the arrival information of vehicles in real time through bus electronic stop signs, mobile hand-held bus short messages and Suzhou Mobile Life Network. According to the statistics of the transportation department, the number of SMS inquiries of handheld buses has reached as many as 800 people every day.
