Problems solved by technology

There are great limitations in the artificial simulation method, and it is impossible to simulate the real road driving scene, which will lead to the inability to accurately classify user trajectories and affect the classification effect of user trajectories.
[0004] In addition, in the existing classification methods of driving trajectories, usually only the speed or acceleration of the driving trajectory is considered to classify the user trajectories. Due to the lack of trajectory features, this will also lead to the inability to accurately classify the user trajectories. , affecting the classification effect of user trajectories

Abstract

The embodiment of the invention discloses a driving track classification method and device, electronic equipment and a storage medium. The method comprises the following steps: receiving a track log of a user driving track point; calculating track characteristics corresponding to each driving track point, track characteristics corresponding to every two adjacent driving track points and track characteristics corresponding to all the driving track points according to the track logs; according to the track characteristics corresponding to each driving track point, the track characteristics corresponding to every two adjacent driving track points and the track characteristics corresponding to all the driving track points, and the track characteristics corresponding to the sample track points,the track characteristics corresponding to every two adjacent sample track points and the track characteristics corresponding to all the sample track points which are determined in advance, determining the track type of the driving track. Therefore, the user tracks can be accurately classified, and the labor cost and the time cost can be saved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of the Internet, and in particular, to a classification method, device, electronic equipment, and storage medium for driving trajectories. Background technique [0002] When a user uses a map application APP product, such as driving navigation, walking navigation, cycling navigation and other scenarios, the server will generate the user's trajectory data according to the coordinates of the user's real-time positioning. The trajectory data of these users, as the basic data of users in map products, contains rich user information and is widely used in scenarios such as road congestion prediction, user travel habit mining, user travel model establishment, and road traffic discovery. . However, when generating the user's trajectory data, different trajectory types such as motor vehicle trajectory, electric vehicle trajectory, walking trajectory, bus trajectory, and subway trajectory wi...
