Method and device for extracting traffic limitation at road intersection

Abstract

The invention provides a method and device for extracting traffic limitation at a road intersection, and the method comprises the steps: obtaining the traveling information of a plurality of vehicles at one road intersection in real time, and obtaining the traveling tracks of the vehicles at the road intersection according to the traveling information; obtaining a plurality of passage links of the road intersection under the condition of no traffic limitation; enabling the traveling tracks of the vehicles to be matched with the passage links, and obtaining the traffic condition of the road intersection; and obtaining the traffic limitation information of the road intersection according to the traffic condition of the road intersection. The method provided by the invention solves a problem that the traffic limitation information of the road intersection is difficult, improves the data collection efficiency and accuracy, provides a safer intersection for a user for travel, reduces the violation at the road intersection, and provides a safer and faster driving environment.

Description

technical field [0001] The invention relates to the technical field of navigation, in particular to a method and device for extracting road intersection traffic restrictions. Background technique [0002] At present, the traffic restriction information of most road intersections needs to be collected by a special collection company to find the intersection traffic restrictions, and the situation at the intersection changes frequently, and the collection cost is relatively high. At the same time, due to the problem of the update strategy, sometimes the change of the traffic restriction at the intersection cannot be detected in time, resulting in the slow update of the traffic restriction information manufacturer at the intersection, and the latest traffic restriction information cannot be sent to the user, causing the user to use the navigation at the intersection Sometimes the route plan is inconsistent with the scene, which affects driving safety, causes users to violate re...

[0002] At present, the traffic restriction information of most road intersections needs to be collected by a special collection company to find the intersection traffic restrictions, and the situation at the intersection changes frequently, and the collection cost is relatively high

At the same time, due to the problem of the update strategy, sometimes the change of the traffic restriction at the intersection cannot be detected in time, resulting in the slow update of the traffic restriction information manufacturer at the intersection, and the latest traffic restriction information cannot be sent to the user, causing the user to use the navigation at the intersection When the route plan is inconsistent with the scene, it will affect driving safety, cause users to violate regulations, or waste time
