The invention relates to a viaduct ramp intelligent signal control method and device based on array radars. The viaduct ramp intelligent signal control method comprises the following steps that multiple array radar detection devices are installed on a viaduct, and a signal machine device is arranged in front of an entrance ramp of the viaduct; real-time traffic parameter information of a road section in a detection area is obtained, the average traffic flow density parameter of the road section in the detection area is calculated in real time, and a density-operation index model is established, and the real-time traffic operation index of the road section in the detection area is extracted; the average traffic operation index of the entrance ramp is calculated; the signal conditioning rate of ramp signal control is set, the real-time signal control green-time ratio is calculated, and an operation index-green-time ratio model is established; the signal machine device controls signals of the entrance ramp of the viaduct by calling the operation index-green-time ratio model in a database. By the adoption of the viaduct ramp intelligent signal control method and device based on the array radars, the accuracy of viaduct traffic event detection and the traffic flow operation efficiency can be improved.
