The invention relates to a jamming index detecting method for a traffic intersection before signal lamps. The detecting method comprises the steps that (1) an image collecting device is used for shooting the traffic intersection before the signals lamps, and an intersection image is obtained; (2) an image processing device is used for conducting image processing on the intersection image to obtain the jamming indexes of all lanes of the traffic intersection; (3) a 3G communication device is used for sending the jamming indexes of all the lanes of the traffic intersection to a far end traffic management platform and receiving signal lamp control signals fed back by the traffic management platform; (4) based on the signal lamp control signals, a signal lamp control device used for controlling the red light duration and the green light duration of all auxiliary lamps of the signal lamps. The method further comprises the step of using a haze removing processing device to execute sharpness processing on the intersection image. By means of the jamming index detecting method, the display of the signal lamps can be controlled according to the actual jamming situation at the traffic intersection even under the serious haze weather, and thus the limited traffic resources are used to the maximum.
