Embodiment Construction

[0033] The exemplary embodiments of the present disclosure are described below in conjunction with the accompanying drawings, which include various details of the embodiments of the present disclosure to facilitate understanding, and they should be regarded as exemplary only. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the disclosure. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

[0034] At this stage, the active discovery of road blockage information is mainly through user trajectory mining and Internet information, and trajectory mining is the most accurate way to find the time and location of blockages. However, it takes one day for the accumulation of user trajectories to output, and the shortest time-consuming needs to be more than 20 mi...

Abstract

The invention discloses a method and a device for discovering road blocking, equipment and a storage medium, and relates to the technical field of data processing, in particular to the technical field of intelligent traffic. The method for discovering road blocking is implemented by comprising the following steps of: acquiring a driving track on a road network based on road network information; drawing a traffic condition diagram according to the driving track; and acquiring blocked road information based on a trigger event by using the traffic condition diagram. According to the method and the device disclosed by the invention, the calculation amount of equipment for discovering road blocking is greatly reduced, the calculation cost is saved, and the real-time response speed is high.

Description

technical field [0001] The present disclosure relates to the technical field of data processing, in particular to the technical field of intelligent transportation. Background technique [0002] In the real world, the dynamic changes of road closures, construction, temporary control, etc., have a great impact on navigation route planning, and are also an important scene that users strongly perceive. Time-sensitive road traffic changes, especially blocking scenarios, used to rely mainly on the Internet and user-generated information to obtain intelligence. Although the accuracy rate is high, it is passive and limited in coverage. We cannot obtain a lot of information immediately. Contents of the invention [0003] The present disclosure provides a method, device, equipment and storage medium for efficiently finding road blockages. [0004] According to a first aspect of the present disclosure, there is provided a method for finding road blockages, including: [0005] Obta...
