Problems solved by technology

At present, there is no intelligent way to judge whether there is a certain road facility at the intersection. If each intersection needs to be manually checked on the spot, it will consume a lot of manpower and material resources

Abstract

A method, system, device and storage medium for judging whether a target road facility exists at an intersection. The method includes: acquiring left-turn driving trajectory data of a moving object at an intersection to be tested (710), extracting characteristic parameter information associated with a target road facility from the trajectory data (720), and determining an intersection to be tested based on the characteristic parameter information of the intersection to be tested Whether the target road facility exists (730). It can intelligently determine the road facilities at the intersection and reduce the consumption of manpower and material resources.

Description

technical field [0001] The invention relates to the field of traffic management informatization, and more particularly, to a method, system, device and storage medium for judging whether a target road facility exists at an intersection. Background technique [0002] With the intelligent development of urban traffic, in order to realize the intelligent regulation of traffic lights, it is necessary to know the road facilities at the intersection in advance. For example, whether there is a left-turn waiting area at the intersection, whether there are left-turn traffic lights or other traffic control signs, etc. Take the left-turn waiting area as an example, whether there is a left-turn waiting area at the intersection, the timing settings of the traffic lights will be different. If there is a left-turn waiting area at the intersection, the moving objects on the road need to go straight and go first, and then go after turning left. However, some intersections have a left-turn ...
