The invention relates to a traffic data collecting method of a crossing where a signal lamp is located. The method comprises the steps that the crossing where the signal lamp is located is shot with a CCD visual sensor to obtain a crossing image; sharpness processing is performed on the crossing image with a haze removing processor to obtain a sharpness crossing image; image processing is performed on the sharpness crossing image with a congestion index analyzer to obtain a crossing congestion index; signal lamp information is collected in real time with a signal lamp data collector; the crossing congestion index and signal lamp information are obtained with an AT89C51 single chip microcomputer, wherein the AT89C51 single chip microcomputer is connected with the congestion index analyzer and the signal lamp data collector. According to the traffic data collecting method of the crossing where the signal lamp is located, accurate collecting of the traffic data of the crossing where the signal lamp is located under all kinds of weather can be guaranteed, and important evidence is supplied to information issue of local traffic management departments.
