Abstract

The invention discloses a method and device for obtaining a dynamic traffic network map, relates to the technical field of the Internet of vehicles, and aims at solving a problem that a conventional dynamic traffic network map obtaining mode is low in accuracy. The main technical scheme of the invention comprises the steps: obtaining the position information of all vehicles at each segment in the traffic network map in real time; generating vehicle clusters corresponding to the segments according to the position information; obtaining the road condition weight value of each segment according to the vehicle density or operation speeds of vehicle clusters of each segment, and generating a real-time dynamic traffic network map. The method is mainly used for generating the dynamic traffic network map.

Description

technical field [0001] The invention relates to the technical field of Internet of Vehicles, in particular to a method and device for acquiring a dynamic traffic road network map. Background technique [0002] The Internet of Vehicles (Internet of Vehicles) is a huge interactive network composed of information such as vehicle location, speed, and route. It is currently the most important and most active branch of the Internet of Things. In the Internet of Vehicles, the vehicle can complete the collection of vehicle information such as its own environment and status through GPS (Global Positioning System, Global Positioning System), RFID (Radio Frequency Identification, radio frequency identification), sensors, camera image processing and other devices, and The collected information is transferred to the central processor in the cloud through Internet technology, and finally a large amount of vehicle information uploaded by each vehicle is comprehensively processed through co...
