Method, device and system for determining bus position

Abstract

The embodiment of the invention relates to a method, apparatus and system for determining the position of a bus. The method includes the steps of receiving position reporting messages sent by at least one terminal device, wherein each position reporting message contains a service set identifier (SSID), of the wireless local area network of a bus, scanned by the terminal device and the positional information of the terminal device; classifying the position report message with same SSID as a group; and determining the position of the bus corresponding to the SSID in the corresponding group of position report messages respectively according to the position information of the terminal device in each group of the position report messages. Compared with the prior art, the method determines the position of buses according to the positions of terminal devices scanning the SSID of the wireless local area network of the buses. Since the positions of the terminal devices are accurate, the accuracy of determining the position of buses is improved.

Description

technical field [0001] The present application relates to the field of intelligent transportation, in particular to a method, device and system for determining the position of a bus. Background technique [0002] Real-time public transportation is an important direction in the field of intelligent transportation. Accurately know the real-time position of each bus on each bus line. On the one hand, it can provide bus arrival time and waiting time for users who take the bus, so that users Better travel planning; on the other hand, it can also provide a reference for the public transport management department to carry out dynamic departure scheduling and congestion situation control. [0003] How to accurately know the real-time position of each bus on each bus line, the current common practice is: according to the pre-stored departure time and departure interval of each bus line in advance, determine the position of each bus on the bus line. The departure time of the bus; acc...

Problems solved by technology

[0004] However, in actual situations, due to the uncertain factors of road traffic conditions and bus stop time at each station, such as: during rush hour, the traffic conditions are relatively congested, which makes the driving speed slower, and each bus station The large number of people makes the bus stop time at each station longer; while in non-rush hour, the traffic conditions are relatively smooth, which makes the driving speed faster, and the number of people at each bus station is small, making the bus stop time at each station longer. Short, due to the existence of the aforementioned many uncertain factors, it is very inaccurate to obtain the real-time position of the bus directly based on the average driving speed, the time interval between the current time and the departure time in the prior art scheme
