Abstract

The embodiment of the invention provides a vehicle parking behavior determination method and system based on a vehicle track and a storage medium. According to the vehicle parking behavior determination method based on the vehicle track, a target vehicle parking point is acquired, a parking track is drawn according to the parking point according to a time axis sequence, then the center point and the maximum parking radius of the parking point are calculated, and then a corresponding road and a service point cluster on the road are matched according to the parking track; and finally, the distance between each service point in the service point cluster and the central point of the parking point is calculated, wherein the service point of which the distance is not greater than the maximum parking radius is a basic parking service point. The vehicle parking behavior is calculated and analyzed according to the vehicle track obtained by a GPS, and the problem that in the prior art, it is difficult to accurately detect the parking behavior such as refueling in the vehicle track according to the vehicle track data of the GPS is solved.

Description

technical field [0001] The present application belongs to the technical field of vehicle information, and in particular relates to a method, system and storage medium for determining vehicle parking behavior based on vehicle trajectory. Background technique [0002] In the Internet of Vehicles technology, point of information (POI) analysis can accurately analyze the information of vehicle stops and help to understand the driving behavior of vehicles. Vehicles often stop at service points such as logistics parks, gas stations, and service areas. Based on the analysis of information points, information such as the type of goods transported by vehicles and the gas stations commonly used by vehicles can be obtained. Therefore, it is of great significance to obtain the logistics information and the supply chain of trucks by obtaining the information of the stop points of the trucks. When the vehicle is parked, the GPS (Global Positioning System) will upload the vehicle location...
