The invention discloses a traffic information prediction method. The method includes the following steps that: the joint of more than two road traveling paths which are not in a crossroad and are located in an urban traffic map is selected, and the joint is adopted as a reference point, a point which is N metres before the reference point is a terminal point, and a point which is 2N metres behind the reference point is a starting point; the terminal point and the starting point are both provided with one automatic camera and a magnetic line of force, and the lenses of the cameras, facing the joint, perform photographing; measurement time is set, photographed pictures are uploaded to a remote database in the measurement time, and a remote control center calls the images from the database and performs image recognition on the images, so that vehicle density in the images can be obtained through statistics; real-time vehicle density is compared with preset comparison vehicle density, if the real-time vehicle density is lower than or equal to the comparison vehicle density, a message indicating that the traffic is smooth is outputted, and if the real-time vehicle density is higher than the comparison vehicle density, whether congestion exists can be judged according to vehicle speed. The traffic information prediction method of the invention has the advantages of simplicity, small amount of occupied data, simple and convenient computation, high precision and excellent prediction effect.
