However, this simple superposition in the shortest time obviously cannot predict accurately, especially in special cases such as traffic congestion and road rectification, the accuracy rate is even more difficult to guarantee
At the same time, the usual smart station announcement method can only be checked after passengers arrive at the bus stop, which cannot be predicted and is easy to miss the bus

Embodiment 1
[0087] Every time a bus passes through a bus stop every day, the vehicle-mounted module records the time of entry and departure, speed and status of the bus at each stop, and sends the data to the network service module by the network data transmission module. The data sending and receiving module of the network service module collects bus information from all vehicles at any time, and analyzes the real-time bus information in the data analysis module and transmits the analyzed bus information to the database module, which then transmits it to the data analysis module module, the data analysis module calculates the travel time T of each bus between any two stations A and B ab , namely T ab = Inbound time of station B - outbound time of station A. The data analysis module collects the travel time T between any two stations at a fixed time every night ab The shortest time T between sites A and B stored in the database module AB For comparison, when the travel time T ab Short...

The invention relates to the technical field of buses, in particular to a method and system for predicting the arrival time of buses. The method comprises the steps that first, a database is established and updated, the real-time public transportation information of running of all the buses is recorded, and the public transportation information comprises the times and positions of real-time positioning of the buses, the recorded arrival times and departure times of the buses passing through all bus stations in the up direction or down direction, the bus running speed and the bus real-time routes; second, the strategy times of all the strategies of each bus which passes through two different stations in sequence according to the public transportation information of the database are calculated, the longest strategy time in all the strategy times is found out, and the longest strategy time is the predicted time; third, the predicted arrival time of the nearest bus in all inquired routes is calculated, and the road congestion condition and the station reminding state are judged. The method and system for predicting the arrival time of the buses have the advantages that under the special conditions of traffic congestion, road rectification and the like, the arrival times of the buses can be accurately predicted.
Description
technical field [0001] The invention relates to the field of bus technology, in particular to a method and system for predicting bus arrival time. Background technique [0002] Bus arrival time prediction technology is the key to intelligent and informatized bus system. The commonly used calculation method for predicting bus arrival time is to directly collect the time of all vehicles passing through any station, and find the shortest time among adjacent stations. The predicted time is equal to the superposition of the shortest time used by each adjacent station. However, this simple superposition in the shortest time obviously cannot predict accurately, especially in special cases such as traffic congestion and road rectification, the accuracy rate is even more difficult to guarantee. At the same time, the usual smart station announcement method can only be checked after passengers arrive at the bus stop, which cannot provide predictions and is easy to miss the bus. Cont...
