City real-time traffic and road condition information issuing method based on traffic video

Abstract

The invention relates to a city real-time traffic and road condition information issuing method based on a traffic video. The method comprises the following steps of: detecting floating cars in various road sections of a road network, uploading speed information to a background server in real time, and using a traffic video monitoring device to upload traffic dynamic information around all monitoring points to the background server in real time; using the background server to determine a real-time traffic state extraction result according to the sample distribution of the floating cars and the information acquisition state of the traffic video monitoring device, and further dividing traffic and road condition information issuing levels by combining with traffic information; and simultaneously extracting FCD (floating car data) and video road condition information at each issuing level, and issuing to the public based on a video way. According to the method disclosed by the invention, the characteristics of the floating cars and the traffic video monitoring device are fully utilized for complementing each other, thus the accuracy in road traffic state extraction and the information practicality are improved, the video-based city traffic and road condition information issuing is realized, and the maximization of receiving of the traffic information by travelers can be ensured.

Description

technical field [0001] The invention relates to the field of traffic information release, in particular to a method for releasing urban real-time traffic road condition information based on traffic video. Background technique [0002] At present, traffic and road condition information is mostly collected from a single source such as manual or video surveillance, and road condition information is released through broadcasting, websites, etc. In recent years, with the maturity of FCD technology and video surveillance technology, it has provided a good foundation for the study of new road condition information release methods. FCD (Floating Car Data) uses the vehicle position change information collected by floating cars to monitor real-time road traffic status. The dynamic extraction system uses the floating car with GPS to collect the displacement information of the vehicle in real time, matches the time series vehicle position coordinates with the map, and obtains the speed ...

Problems solved by technology

[0003] The FCD system can extract the traffic status of the main roads and branch roads of the entire road network in real time through the speed calculation model. The form of traffic status information cannot be quickly accepted and understood by the majority of travelers, which reduces the utilization rate of information

In addition, compared with the FCD system, the traffic video surveillance system provides more accurate, rich, and intuitive traffic information through video images, but limited by the distribution scale of video surveillance equipment, it can only detect the traffic conditions of important arterial roads or nodes, and the overall analysis is relatively difficult. Weak; At the same time, severe weather, lighting and other external environments will affect the accuracy of video detection results
