The invention discloses a road traffic information acquisition device, which comprises a processing unit and an information acquisition unit, and is characterized in that the information acquisition unit is arranged at a preset road section and is used for acquiring road basic information and traffic light time sequence information in the preset road section; the processing unit comprises a preprocessing module, a processing module and a traffic indication module, and the preprocessing module carries out region segmentation based on received road basic information to obtain a preprocessing view and sends the preprocessing view to the processing module; the processing module obtains vehicle basic information in a pre-processing view area based on the received pre-processing view, calculates the passing duration of passing through a preset road section and sends the passing duration to the traffic indication module, and the vehicle basic information comprises vehicle type information, vehicle speed information and occupied lane length information; and the traffic indication module compares the received passing duration with the indication lamp time sequence information, and sends a traffic indication lamp time sequence adjustment instruction to a traffic management center if a difference value between the received passing duration and the indication lamp time sequence information exceeds a preset threshold value. The traffic pressure can be relieved based on real road condition guidance and adjustment.
