Method and system for generating travel track, storage medium and electronic device

Technical Field

The invention relates to the field of intelligent transportation, in particular to a method and a system for generating a vehicle driving track, a storage medium and an electronic device.

Background

With the rapid development of domestic economy, the automobile industry is developed vigorously, and the automobile keeping quantity of the whole country reaches 2.5 hundred million and two in the first half of 2019, wherein the automobile keeping quantity of private cars reaches 1.98 hundred million. The modern Chinese expressway is developing towards intellectualization, and gradually forms the scientific and technological idea of 'intelligent expressway'. The intelligent expressway proposes and introduces Internet thinking and technology, reconstructs and reconstructs traditional expressway electromechanical systems and management services, and the initial construction task is to improve the operation management level and the trip service quality of the expressway through information exchange and sharing, data fusion and mining, thereby realizing informatization and intellectualization of services such as provincial expressway monitoring management, emergency command, auxiliary decision, business handling, trip guidance and the like. The future development trend of the intelligent expressway is to introduce a vehicle-road communication technology to realize the cooperation of people, vehicles, roads and environment.

In the related art, charging vehicles based on the driving tracks of the vehicles is a key technology for highway charging, and charging according to the areas where the vehicles pass and the congestion degree of roads in future urban roads are also called as key technologies. At present, in the highway Toll Collection system, send the broadcast signal through 5.8G antenna through portal ETC system usually, on-vehicle label in the vehicle or compound pass card (CPC card) are awaken up the back by the broadcast signal, carry out information interaction with portal Electronic Toll Collection (ETC for short) system to obtain the identification point information that portal ETC system corresponds (identification point information is used for only identifying a portal ETC system) and save, and then generate the orbit of traveling of vehicle according to the identification point information of saving. However, in this scheme, because information interaction between the vehicle-mounted tag or the CPC card and the portal ETX system and information interaction between the portal ETX system and the vehicle-mounted tag or the CPC card take a long time, the situation that interaction between the vehicle-mounted tag or the CPC card and the portal ETX system fails when the vehicle speed is too fast is caused, and thus information acquisition of the identification point fails, and further a part of a driving track in the driving process of the vehicle is lost, and therefore the accuracy of the generated driving track is low, and therefore, the problem that charging is abnormal occurs when the communication fee corresponding to the vehicle is determined according to the driving track of the vehicle is determined.
