Real-time public transportation information service system

Abstract

The invention discloses a real-time public transportation information service system, which comprises 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 query real-time public transportation information including the vehicle arrival time and the vehicle operating state through the service application programming interface. The real-time public transportation information service system disclosed by the invention processes abnormal conditions of vehicles in the public transportation service system, can carry out real-time processing on a great amount of public transportation information data quickly, and is high in efficiency. The abnormal conditions in real-time public transportation information are considered comprehensively, and queried vehicles and the operating states of all vehicles in the system are displayed in real time. Meanwhile, the real-time public transportation information service system has the advantages of accurate forecast for the arrival time of vehicles and quick query for the real-time public transportation information.

Description

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

AI Technical Summary

Problems solved by technology

[0004] (1) The amount of data is large, and the number of urban buses is large. Each vehicle generates a piece of data every 20 seconds. These generated data must be processed in real time to provide information services;

[0005] (2) There are many and complex data abnormalities, and there are various 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 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
