A real-time bus information service system

Abstract

The invention discloses a real-time bus information service system, which includes a service application programming interface, a data access interface, a vehicle arrival time prediction module, a vehicle arrival time prediction accuracy evaluation module, a real-time data processing module, an event statistics module, and a vehicle real-time state monitoring Module, users can query real-time bus information including vehicle arrival time and vehicle operation status through the service application programming interface. The real-time public transportation information service system of the present invention handles the abnormal situation of the vehicle in the public transportation information service system, can carry out fast real-time processing to a large amount of public transportation information data, efficient; Displays the running status of the query vehicle and all vehicles in the system; at the same time, it has the advantages of accurate forecast of vehicle arrival time and fast query of real-time bus information.

Description

technical field [0001] The invention relates to the field of intelligent transportation, in particular to a real-time bus information service system. Background technique [0002] In the field of intelligent transportation, the use of real-time public transportation information service system can significantly improve the service level of public transportation and attract more passengers to use public transportation. The real-time bus information service system provides real-time bus information service for passengers waiting at the bus station by processing the geographical location data sent regularly by the bus in real time. Passengers can query the relevant information of the vehicle in real time, such as the current location and the distance from the waiting station , to estimate the running time of the vehicle and other information. [0003] The ground location data sent by the bus in real time has the following characteristics: [0004] (1) The amount of data is lar...

Problems solved by technology

[0005] (2) There are many and complex data abnormalities, and there are many types of positioning equipment on the vehicle. Due to the influence of various objective and unpredictable factors such as the accuracy of satellite positioning, the limitation of positioning equipment, and network signals, there are a large number of abnormal data in the data.

[0007] First, it is impossible to quickly process a large amount of location data in real time;

[0008] Second, it is not comprehensive enough to consider the anomalies in the data

The current real-time bus information service system does not have too much design for the state of the vehicle, which will cause some vehicles in an abnormal state to be displayed to the user as vehicles in a normal operating state, and at the same time it is impossible to understand the status of all vehicles in the entire system general condition

[0009] Third, the accuracy of the vehicle arrival time forecast should be assessable, the operating status of the system should be monitorable, and the system operation log should be analyzable, but the existing real-time bus information service system does not fully consider the above question
