Problems solved by technology

[0004] However, there is currently no method to quantify how often moving objects enter and exit frequent routes
Therefore, it is currently impossible to analyze the trajectory frequency as a factor of behavior analysis and safety risk, which brings great difficulties to the behavior analysis of moving objects and safety risk evaluation.

Embodiment Construction

[0024] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0025] figure 1is a flowchart of a method for calculating track frequency according to an exemplary embodiment of the present disclosure. Such as figure 1 As shown, the method may include the following steps:

[0026] In step 110, a set of trajectories of the moving object is acquired.

[0027] In the present disclosure, the mobile object may refer to a vehicle, a user holding a mobile device, and the like. The trajectory can be, for example, the driving trajectory of the vehicle, and the data can be obtained by a GPS device, including longitude, latitude, time and other information of a series of location points passed by the vehicle. The continuous loc...

Abstract

The present disclosure relates to a method, an apparatus, a storage medium, and an electronic device for calculating a trajectory frequency. The method comprises the following steps of: acquiring a track set of a moving object; the trajectories in the trajectory set being clustered based on the trajectory similarity, so that that track group being obtained, and obtaining a number of tracks in theset of tracks that are not similar to any other tracks, as the total number of trajectories in the trajectory set is positively correlated with the trajectory frequency, the number of trajectory groups is negatively correlated with trajectory frequency, the number of trajectories that are not similar to any other trajectories is negatively correlated with the trajectory frequency, which can accurately calculate the trajectory frequency of moving objects on the frequent routes represented by these groups, and provides a new quantitative index for the behavior analysis of moving objects and thesafety risk assessment.

Description

technical field [0001] The present disclosure relates to the field of data processing, and in particular, to a method, device, storage medium and electronic equipment for calculating track frequency. Background technique [0002] With the rapid development of Internet of Things technology, a large amount of travel data of mobile objects has been accumulated. For example, in the field of Internet of Vehicles, a large amount of driving data of users has been accumulated. At present, the user's behavior analysis and safety risk assessment are generally carried out through the travel time, mileage, speed, and road status in the driving data. [0003] For mobile objects such as private car owners or fleets, with the accumulation of data, the distribution of trajectories will concentrate on certain routes, which can be called frequent routes. The frequency of frequent routes is closely related to the travel rules of mobile objects, and is one of the factors that determine the be...
