Abstract

The embodiment of the invention discloses a method and device for determining traffic light crossings, and an electronic device. The method includes: acquiring coordinates of each traffic light crossing and static data of each road segment chain; according to the position information of each road segment chain, generating at least one first road according to the manner that each road segment chaincorresponding to a same road marking is connected in sequence; and segmenting each first road according to the coordinates of each traffic light crossing, to determine the road segments related to each traffic light crossing. In this embodiment, the first road corresponding to the same road marking is generated by the position information of each road segment chain and the first road is segmentedaccording to the coordinates of the traffic light crossing, to automatically and accurately determine each traffic light crossing at high speed and high efficiency, and determination of batch of traffic light crossings can be realized.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of traffic, and in particular to a method, device and electronic equipment for determining a traffic light intersection. Background technique [0002] With the rapid growth of the national economy, urbanization has been vigorously promoted as the direction of national development, followed by the rapid expansion of the population and car ownership in large cities. Urban traffic congestion is a common problem faced by cities across the country. And just like the old saying "haste makes waste", the more congested the road, the easier it is for the reasonable traffic order to be destroyed. Especially at intersections, the backlog of vehicles caused by congestion in one direction will eventually affect the traffic in other directions at the intersection. Congested traffic is paralyzed, which in turn affects the efficiency of the entire traffic road network and seriously wastes social ...
