The invention provides an urban road downstream directional traffic state judgment method based on a video detector. At present, judgment of the urban road traffic state is mainly based on floating vehicle data, and differences of the passenger loading rate and the vehicle operation rate of a floating vehicle at different time periods are large, so that the data sample number is insufficient, and distribution is uneven. According to the urban road downstream directional traffic state judgment method, the road section traveling time of different traffic streams in a road section is obtained through the video detector, and the road section traffic jam indexes of the different traffic streams in the road section are then constructed for conducting traffic state judgment on the different traffic streams. By means of the urban road downstream directional traffic state judgment method, sufficient data supports are obtained by sufficiently using existing video resources, and the shortcomings that in a traditional inspection method, the sample number is small, and distribution is uneven are overcome; a calculating method for the traveling time and the traveling speed is simple and rapid, and engineering realization is easy; traffic information of various cross sections and various regions are synthesized, the road traffic jam judgment method is provided, and data supports and decision basis are provided for distributing the road resources in a balanced mode and inducing the traffic streams to reasonably run.
