Abstract

Embodiments of the present application provide a method and device for determining lane speed. The lane speed determination method includes: acquiring the first position coordinates of the reference vehicle on the target road section at the first moment and the second position coordinates at the second moment and at least one other vehicle on the target road section at the first moment or the third position coordinates at the second moment; according to the first position coordinates, the second position coordinates and the third position coordinates, determine the distance between the lane where the other vehicle is located and the lane where the reference vehicle is located relative positional relationship; determining vehicle information on the target lane according to the relative positional relationship; determining a lane speed of the target lane based on the vehicle information. The technical solution of the embodiment of the present application realizes the detection of the speed of the lane more quickly and accurately.

Description

technical field [0001] The present application relates to the field of computer and communication technologies, and in particular, to a method and device for lane speed. Background technique [0002] At present, determining the speed of the lane is one of the key problems faced by high-precision positioning, vehicle-road coordination, Internet of Vehicles, automatic vehicle platooning, and intelligent transportation. The methods for determining the speed of the lane in the prior art are mainly: 1) Firstly, use the lane GPS positioning technology Determine the correspondence between each lane and GPS; 2) Obtain the GPS coordinates and vehicle speed of each vehicle within a preset time period or road section; 3) Determine which vehicles are on the road according to the correspondence between GPS and lanes On the same lane; 4) For the cars on the same lane, determine the lane speed. However, the solutions in the prior art must rely on the lane GPS positioning technology. Howev...
