The invention discloses a highway traffic flow real-time monitoring and congestion prediction system based on an unmanned aerial vehicle, and relates to the technical field of traffic information. The system comprises an unmanned aerial vehicle platform, a data processing module and an early warning module. The unmanned aerial vehicle platform carries data acquisition equipment and is used for acquiring real-time road condition information of the expressway and transmitting the road condition information to the data processing module; the road condition information comprises video information collected by the unmanned aerial vehicle platform in real time; the data processing module is used for performing operation and analysis based on the road condition information to obtain an analysis result; and the early warning module is connected with the data processing module and is used for carrying out road state early warning based on the analysis result. Road conditions are collected in real time through the unmanned aerial vehicle, and vehicle identification, tracking and lane line identification are carried out by taking a vehicle and a lane line as analysis targets. Based on the position relation between the lane line and the vehicle and the vehicle speed change curve, traffic flow monitoring and congestion prediction of the expressway are realized.
