AI Technical Summary

Problems solved by technology

Its disadvantages are: there is a phenomenon of positioning offset (especially in places with occluders, such as elevated roads and tunnels)
Its disadvantages are: the cost is high, so the positioning points are relatively sparse and the density is low; the layout position and angle requirements are high

Embodiment Construction

[0028] In order to make the present invention more comprehensible, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings: this embodiment is implemented under the technical solution of the present invention, and the implementation process and effect of the present invention are given. The protection scope of the present invention is not limited to the following examples.

[0029] The present invention employs the following concepts:

[0030] Line: The orderly collection of road sections where buses run along the road is called a bus line;

[0031] Sub-line: A sub-line is a line composed of a set of fixed directional road sections from the starting station to the terminal station of the bus. A bus line is generally composed of sub-lines in two driving directions (up and down / inside and outside circles).

[0032] Uplink and downlink line point collection {SL}: A collection of positioning point coordinate data co...

Abstract

The invention aims at realizing tracking of a driving track of a bus based on integration of a vehicle-mounted GPS positioning technology, an RFID positioning technology and a video detector positioning technology. In order to achieve the objective, the invention provides a multi-data-source-based bus driving track tracking method. A driving track of a bus is determined by combining the vehicle-mounted GPS positioning technology, the RFID positioning technology and the video detector positioning technology, so that the driving track of the bus can be tracked accurately.

Description

technical field [0001] The invention relates to a method for tracking the running track of public transport vehicles. Background technique [0002] The current track tracking method of public transport vehicles adopts one of vehicle-mounted GPS positioning technology, RFID positioning technology or video detector positioning technology. [0003] Vehicle GPS positioning technology uses GPS vehicle positioning and navigation technology, according to the bus route arrangement, combined with various information sent back by vehicles (such as traffic jams, locomotive failures, etc.), timely sends scheduling commands to drivers, and timely adjusts vehicle operation. This technology can also be applied to the query function of relevant data such as vehicles, routes and roads, which is convenient for effective management. [0004] The advantage of this technology is that the collection points are dense, and when the vehicle is powered, one piece of data will be obtained every 5 sec...
