Abstract

The invention provides a target road matching method through vehicle positioning information and a system thereof. The method comprises the steps that a coordinate collection of points within preset width of areas of the two sides of mileage pegs on a target road is calculated according to mileage peg number information of the target road and the azimuth of the connecting line of the adjacent mileage pegs; Geohash processing is performed on the coordinate collection, obtained Hash result values act as Key values, and two adjacent mileage peg numbers corresponding to each Key value act as Value; Geohash processing is performed on real-time positioning information of a vehicle to be tested so that a corresponding Hash result value is obtained; a memory database is inquired according to the Hash result value corresponding to the positioning information of the vehicle to be tested and whether the vehicle to be tested is currently driven on the target road is judged; when the vehicle to be tested is driven on the target road, effective positioning point information of the vehicle to be tested within preset time before the current positioning point is inquired; and the driving route and direction of the vehicle to be tested are judged according to the mileage peg numbers corresponding the current real-time positioning information of the vehicle to be tested and the information of at least one effective positioning point.

Description

technical field [0001] The invention relates to a method and a system for matching vehicle driving roads with vehicle positioning information acquired by a global navigation satellite system (Global Navigation Satellite System, GNSS). Background technique [0002] In the GNSS monitoring system of large-scale road transport vehicles, there are many online vehicles, and the real-time positioning data received by the GNSS monitoring system is huge. It is difficult to analyze and process these data in a timely manner, and it is impossible to match the road on which the vehicle is driving based on the positioning information of the vehicle. . [0003] The road transport vehicles involved in the present invention refer to the road transport vehicles referred to in the "Measures for the Dynamic Supervision and Administration of Road Transport Vehicles" (Order No. 5, 2014), including passenger vehicles for road operations, dangerous goods transport vehicles, and semi-trailer tractor...
