Method and system for judging vehicle retrograde violation based on GPS position information

Abstract

The invention provides a method and system for judging vehicle retrograde violation based on GPS geographic position information. The method comprises the steps of dividing an electronic map into a plurality of grids to obtain a refined main road grid map in a city, marking lane lines in the grid map, and determining and recording correct advancing directions of a left lane line and a right lane line; projecting an original point on a vehicle running track to a lane corresponding to the grid map to obtain a matched mark point on the grid map; and determining the traveling direction of the vehicle according to the position change of the mark point on the vehicle running track, and judging whether the vehicle travels illegally. According to the technical scheme, the vehicle position information in the geographic space can be accurately matched into the electronic map, the vehicle running track can be quickly judged, vehicle driving is effectively standardized, the problem that vehicles on urban main roads violate the rules and run reversely is solved, and the occurrence rate of traffic accidents is reduced.

Description

technical field [0001] The invention relates to the field of GPS navigation, in particular to the field of GPS positioning map matching, and is a method for judging vehicle retrograde violations based on GPS geographic location information. Background technique [0002] With the growth of domestic vehicle ownership, the traffic in cities (especially cities like Beijing, Shanghai, Guangzhou, and Shenzhen) is becoming increasingly congested and deteriorating. Over the years, domestic and foreign practical experience has proved that solving urban traffic problems Simply relying on the improvement of road infrastructure is not effective. In addition to the corresponding macro-traffic policy support, modern traffic management is also a very important part. With the development of high-tech such as electronic technology, communication technology, computer technology, etc. The integration of accurate electronic map matching and GPS navigation system has become an intelligent transp...

AI Technical Summary

Problems solved by technology

Existing algorithms cannot more accurately determine which lane the vehicle is driving in and whether there is a retrograde behavior, which makes the matching algorithm need to be continuously improved to achieve the ideal positioning effect
