Embodiment Construction

[0054] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0055] Before explaining and describing the embodiments of the present invention in detail, the application scenarios of the embodiments of the present invention will be described first.

[0056] The embodiment of the present invention is applied to the scene where the road condition of the target road section needs to be determined, wherein the target road section refers to the road section connected to the traffic light, for example, the road section 100 meters or 200 meters before the light. Specifically, when the vehicle arrives at the target road section, the road condition state of the target road section can be released to the vehicle, so that the user can estimate the driving time on the target road section according to the publ...

Abstract

The invention discloses a road condition state determination method and device, and belongs to the traffic field of road traffic. The method comprises the steps of acquiring driving information of multiple first vehicles of a target road segment, wherein each first vehicle is a vehicle of which the vehicle position is arranged at the target road segment within preset time, and the driving information comprises driving track and lamp waiting information; determining road condition characteristic of the target road segment according to the driving information of multiple first vehicles, whereinthe road condition characteristic of the target road segment comprises numbers of the first vehicles at different driving information zones within at least one time frame in the preset time; and calling a road condition identification model, inputting the road condition characteristic of target road segment into the road condition identification model, and outputting the road condition of the target road segment. By the method, the accuracy and the efficiency of road condition determination can be improved.

Description

technical field [0001] The invention relates to the technical field of road traffic, in particular to a method and device for determining road conditions. Background technique [0002] At present, traffic congestion has become an increasingly prominent problem in major cities. In order to facilitate users to travel, the navigation software can provide users with a traffic query function. Through this traffic query function, users can query the traffic status of each road section and choose a suitable road section. drive. Wherein, the road condition state of the road segment usually includes the states of congestion, slowing down, and smooth flow. In addition, because most of the roads in the city are equipped with traffic lights, vehicles are easily affected by the traffic lights when driving on the road. Therefore, it is also necessary to accurately display the traffic status of the road before the lights, that is, the target connected to the traffic lights on the road. T...
