Abstract

The invention provides a real-time acquisition device for an automobile flow of an urban expressway. The device is fixed on a lamppost at a ramp crossing of the urban expressway, wherein a card reader in the acquisition device is used for reading card-type compulsory traffic insurance signs pasted on front windshields of automobiles entering or running out of the ramp crossing of the urban expressway, so that acquisition of the automobile flow is realized; and acquired information of the automobile flow is sent to a control circuit of a traffic management center regularly by using a radio communication circuit in the device.
