The invention discloses a road information real-time acquisition device and method based on a traffic monitoring video. The device is characterized in that the device comprises a video processor, a network module, a remote server, a data pusher and a data receiver. The video processor reads a video image corresponding to a monitoring device. According to acquired pictures, the grayscale value X of each pixel in each picture is acquired, and is compared with a pre-stored parameter value X-1. A nuclear method is used to assess road congestion extent ci, and ci is uploaded. A remote server carries out real-time analysis to acquire a road congestion extent value C. The data pusher transmits the information of a congested road to the data receiver, and the data receiver outputs the information. According to the invention, the video processor analyzes the real-time image grayscale; the nuclear method is used to assess and upload the congestion extent; the data pusher transmits the information in real time; the receiver carries out real-time broadcasting; a driver can acquire the road information in real time and can timely plan a route; and congestion is reduced.
