A Judgment Method of Whether Key Vehicles Travel According to Specified Routes

Abstract

The invention discloses a method for judging traffic violations of key vehicles that do not travel along prescribed routes, which generates a traffic record set of target key vehicles through highway bayonet equipment; screens out the reported routes corresponding to the reported routes from the road network layer according to the reported routes of key vehicles. Generate the GIS layer of the initial planned route, and then obtain the intersection point to generate the GIS layer of the necessary points of the initial planned route; use the GIS system to display the traffic record set on the map, and establish the automatic calculation of the route after buffer analysis and ambiguity point elimination The process is to generate the GIS layer of the actual route trajectory of the vehicle, and generate a new GIS layer of the planned route from the GIS layer of the necessary points of the initial planned route combined with the spatial topological relationship of the road network; superimposed on the road network dataset with different colors The system automatically judges the matching degree of the planned route GIS layer and the actual route track GIS layer. The invention judges whether the vehicle runs according to the prescribed route by forming the driving trajectory through the bayonet traffic information, without installing GPS equipment.

Description

technical field [0001] The invention relates to the field of road transportation management, in particular to a method for judging whether key vehicles are traveling according to a prescribed route through data analysis of bayonet traffic information. Background technique [0002] The traffic and transportation supervision departments in various places mainly adopt the "two passengers and one dangerous" key vehicle route supervision methods as follows: first, install GPS (Global Positioning System) equipment on key vehicles, and secondly obtain vehicle location and time positioning information in real time through GPS, and then The background system of the monitoring center matches and displays the driving route trajectory on the map, and finally manually compares the route reported by the key vehicles with the driving route trajectory displayed by the system, so as to judge whether the vehicle is driving according to the specified route and time. However, this supervision m...

However, this supervision method requires key vehicles to actively report positioning information through the vehicle-mounted GPS device. For example, in the case of human intervention or the vehicle is not equipped with a vehicle-mounted GPS device, the monitoring center cannot receive positioning information to form a driving route trajectory, so that it is impossible Judging whether the vehicle is driving according to the prescribed route, losing the ability to supervise
