Real-time traffic flow prediction method and device for target road

The invention relates to the technical field of intelligent traffic, and in particular, relates to a target road real-time traffic flow prediction method and device. The target road real-time traffic flow prediction method comprises the steps: acquiring traffic flow basic characteristics of a target road and real-time speed data of a floating car; according to the traffic flow basic characteristics of the target road, obtaining a traffic basic diagram of a road section similar to the target road, wherein the traffic basic diagram is suitable for establishing a relationship between traffic flow and driving speed of the road section; determining the real-time passing speed of the target road according to the real-time speed data of the floating car; and determining the real-time traffic flow of the target road according to the real-time passing speed based on the traffic basic diagram. According to the invention, the real-time traffic flow of the target road is detected, the real-time traffic operation conditio
