Problems solved by technology

[0004] In the process of realizing the present invention, the inventor found that the existing technology has the following defects: the existing technology can only monitor and broadcast the road conditions in a lagging or quasi-real-time manner, and cannot predict the road conditions in advance
For example: when a car breaks down on a road, it may take 5 minutes before congestion occurs. At this time, the road condition server can know that the road condition has been congested, and then notify other vehicles to make a detour. During this waiting time, Vehicles entering this road will inevitably be congested

Embodiment 1

[0025] figure 1 It is a flow chart of a method for predicting a congested road section provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation of predicting a road section that is about to be congested. , the device can be implemented in the form of software and / or hardware, and can generally be integrated into a server. Typically, the server is a navigation server and is used in conjunction with a navigation client. like figure 1 As shown, the method of this embodiment specifically includes:

[0026] S110. The server acquires location-related information of the abnormal vehicle sent by at least one vehicle-machine terminal, wherein the location-related information includes: location information of the abnormal vehicle, and abnormal time information.

[0027] Generally speaking, car machine refers to the abbreviation of in-vehicle infotainment products installed in the car. The car machine must be able to realize information communic...

Embodiment 2

[0049] figure 2 It is a flowchart of a method for predicting congested road sections provided by Embodiment 2 of the present invention. This embodiment is embodied on the basis of the above-mentioned embodiments. In this embodiment, according to the obtained location-associated information obtained by the server, Predicting the congested road section in the map specifically includes: the server filters out the position information of the first target abnormal vehicle corresponding to the set time interval according to the abnormal time information; the server selects the location information of the first target abnormal vehicle according to the Position information, determine the first road section where the first target abnormal vehicle is located in the map; the server predicts the first road section including the first target abnormal vehicle quantity exceeding the vehicle threshold as a congested road section; For the predicted result of the road section, execute a corres...

Embodiment 3

[0069] image 3 It is a flow chart of a method for predicting congested road sections provided by Embodiment 3 of the present invention, and this embodiment is embodied on the basis of the foregoing embodiments. In this embodiment, the location-associated information may further include: abnormal vehicle state information; the server predicts the congested road section in the map according to the obtained location-associated information, specifically: the server predicts the congested road section according to the abnormal Time information, screening out the position information of the second target abnormal vehicle corresponding to the set time interval, and the status information of the second target abnormal vehicle; the server determines the second target abnormal vehicle in the map according to the position information of the second target abnormal vehicle The second road section where the target abnormal vehicle is located; the server updates the abnormal grade weight va...

Abstract

The embodiment of the invention discloses a method and a device for predicting a congested road segment, equipment and a storage medium. The method comprises the following steps of enabling a server to obtain the position correlation information of an abnormal vehicle sent by at least one motor vehicle terminal, wherein the position correlation information comprises position information of the abnormal vehicle and abnormal time information; enabling the server to predict the congested road segment in a map according to the obtained position correlation information; enabling the server to execute a corresponding congested road segment processing strategy according to the predicting result of the congested road segment. By adopting the technical scheme, the method has the advantages that the massive data processing and large-scale computing are realized by the server, so that the congested road segment can be predicted in real time; according to the predicting result of the congested road segment, the number of vehicles being driven into the congested road segment is reduced before the road is heavily congested, the traffic congestion is effectively relieved, and the passing efficiency of automobiles and the use experience of a user are improved.

Description

technical field [0001] Embodiments of the present invention relate to information processing technologies, and in particular to a method, device, server and storage medium for predicting congested road sections. Background technique [0002] The rapid growth of car ownership has brought convenience to all aspects of people's lives, and at the same time led to frequent urban road congestion. The problem of traffic congestion is becoming more and more serious, which not only brings environmental pollution, but also causes economic losses. Therefore, it is necessary to study the identification method of traffic congestion, distinguish the state of traffic operation in a timely and accurate manner, take reasonable measures for traffic congestion, and reduce traffic congestion through scientific and reasonable road traffic management methods. [0003] The existing way to alleviate traffic congestion is mainly to calculate the current traffic conditions through the traffic bureau...
