Problems solved by technology

However, these road flow sensing devices only monitor cross-sectional flow, and do not know the specific vehicle travel trajectory
Moreover, due to the high deployment and maintenance costs of road traffic sensing equipment, it is impossible to achieve full coverage of the road network

Abstract

The invention discloses a track processing method and apparatus, electronic equipment and a computer readable storage medium. The processing method comprises the steps of acquiring a sampling track passing through a preset area in a preset statistical time period and a traffic flow monitored by a road flow sensing device arranged in the preset area, wherein the sampling track comprises a first sampling track passing through the road flow sensing device; conducting incremental updating on the first sampling track according to the traffic flow so as to obtain a first full track passing through the road flow sensing device; and acquiring a full track in the preset area according to the first full track.

Description

technical field [0001] The present invention relates to the technical field of traffic control, and more specifically, to a trajectory processing method, a trajectory processing device, an electronic device, and a computer-readable medium. Background technique [0002] With the popularization of GPS (Global Positioning System, Global Positioning System) equipment, more and more vehicles in cities will record tracks through GPS when traveling. Trajectories are big data used to estimate urban travel information. Mastering the complete urban traffic travel information is very important for urban traffic management. [0003] Existing tracks can be acquired through a GPS device installed on the vehicle, or through a navigation application. Extracting trajectories from navigation applications has become an important data source for grasping urban travel characteristics. However, not all vehicle trips will use the specified navigation application. Therefore, the trajectory extra...
