Abstract

An embodiment of the invention discloses a vehicle information collection method and apparatus. A probe vehicle continuously receives traffic information according to a fixed frequency. The method comprises obtaining a current driving speed of the probe vehicle; when the current driving speed is determined to be inconsistent with a previously obtained driving speed of the probe vehicle, obtaining a traffic information acquisition frequency corresponding to the current driving speed from a preset corresponding relation between the driving speed and the traffic information acquisition frequency; and according to the traffic information acquisition frequency, acquiring traffic information to be uploaded from the traffic information received by the probe vehicle when the current driving speed is obtained. That traffic information collection points are evenly distributed on the road can be ensured to a certain extent, and with the traffic information having a relatively small amount of uploaded data, a server side is also enabled to obtain accurate traffic conditions through analysis based on the received traffic information.

Description

technical field [0001] Embodiments of the present invention relate to the field of traffic information collection, and in particular, to a traffic information collection method and device. Background technique [0002] Floating car (FCD, Float Car Data) technology, also known as probe car (Probe Car) technology, is one of the advanced technical means used by the International Intelligent Transportation System (ITS) to obtain road traffic information. The basic principle is: the floating car, that is, the car loaded with the traffic information collection terminal, collects and calculates the traffic information of the road traffic state, including: the latitude and longitude information of the location of the floating car, the driving speed of the floating car at this location, and the generation of the traffic information. The time of information, etc.; during the driving process of the floating car, the traffic information collected by the floating car, that is, the traffi...
