Embodiment 1

[0084] Such as figure 1 As shown, it is a flow chart of a method for determining traffic conditions provided in Embodiment 1 of the present application. The above-mentioned method for determining traffic conditions can be applied to electronic devices, and the method specifically includes the following steps:

[0085] S101. Acquire vehicle speed information at different positions of the vehicle on a target driving road.

[0086] Here, in order to realize the determination of the traffic condition, the embodiment of the present application needs to obtain various vehicle speed information of the vehicle on the target driving road, and each vehicle speed information may correspond to different positions.

[0087] Wherein, the above-mentioned vehicle speed information may be calculated based on the track point data of the vehicle on the target driving road, and may also be obtained directly based on equipment such as a speed sensor carried by the vehicle. As for the target drivi...

Embodiment 2

[0097] Such as figure 2 As shown, it is a flow chart of a method for determining vehicle speed information provided in Embodiment 2 of the present application. The method is implemented through the following steps:

[0098] S201. Acquiring track point position information of the vehicle on the target driving road;

[0099] S202. Regarding the position information of any two adjacent track points, determine that the vehicle travels from one track point position of any two adjacent track point positions to the other track of any two adjacent track point positions The duration information occupied by the point position;

[0100] S203. According to the obtained position information of any two adjacent track points and the duration information corresponding to the position information of the two adjacent track points, determine the two adjacent track points of the vehicle on the target driving road Vehicle speed information between locations.

[0101] Here, in order to facilita...

Embodiment 3

[0107] Such as image 3 As shown, it is a flow chart of a method for determining traffic condition information provided in Embodiment 3 of the present application. The method specifically includes the following steps:

[0108] S301. Input all vehicle speed information on the target driving road into a pre-trained traffic condition representation model to obtain speed feature vectors corresponding to all vehicle speed information;

[0109] S302. Determine traffic condition information of the target driving road based on the obtained speed feature vector.

[0110] Here, after receiving all the vehicle speed information on the target driving road, based on the mathematical method: word2vec, the vehicle speed information can be converted into digital information in the form of a vector (that is, the speed feature vector) for machine recognition. There are two main types of common vector transformation models, one is a vector transformation model based on One-hot Representation, a...

Abstract

The invention relates to the technical field of traffic, in particular to a traffic condition determination method and device, electronic equipment and a storage medium, and the method comprises the steps of obtaining vehicle speed information of a vehicle at different positions on a target driving road; and determining traffic condition information of the target driving road based on the vehiclespeed information of different positions on the target driving road and a preset traffic condition representation model. According to the invention, the traffic condition information of the target driving road is determined through the preset traffic condition representation model, so that the real traffic condition is effectively and accurately determined.

Description

technical field [0001] The present application relates to the field of traffic technology, in particular, to a method, device, electronic device and storage medium for determining traffic conditions. Background technique [0002] Accurate traffic information can provide effective travel planning for transportation. The so-called traffic road condition information mainly refers to the speed information of the vehicle traveling on the entire road. [0003] A method for determining traffic conditions is provided in the related art, which can calculate an average speed based on vehicle-related position information and corresponding time information, and generate road congestion information based on the average speed, that is, when the average speed is relatively small Under the circumstances, it can be preliminarily considered that there may be congestion problems in the road section. This method of determining road conditions based on the average speed has the problem of low ...
