The invention discloses an intelligent expressway active traffic flow control method and system, and relates to the technical field of intelligent expressway active control, the system comprises a data layer, a platform layer and an application layer, and the data layer, the platform layer and the application layer are included. The data layer fuses and processes multivariate data through a road state sensing device, a meteorological station, a visibility meter and the like, the platform layer combines a basic algorithm and a service platform to provide data, and the application layer provides real-time traffic flow information according to the real-time traffic flow state. An active traffic flow control scheme is generated through a variable speed limit control technology, a single-point ramp control technology, a real-time traffic state prediction technology, a ramp cooperative control technology, a ramp main line cooperative control technology and a multi-strategy and whole-line space-time cooperative control technology, and then control information is issued based on a control facility. According to the invention, the real-time traffic flow can be monitored, the road is actively controlled, and the purposes of reducing the road accident risk and improving the traffic efficiency are achieved.
