The invention relates to a signal lamp crossing traffic data collecting system comprising a CCD (Charge Coupled Device) visual sensor, a smog removing processor, a congestion index analyzer, a signal lamp data collector and an AT89C51 single chip microcomputer. The CCD visual sensor is used for shooting a crossing where a signal lamp is located to obtain a crossing image. The smog removing processor is used for sharpening the crossing image to obtain a sharp crossing image. The congestion index analyzer is used for processing the sharp crossing image to obtain the congestion index of the crossing. The signal lamp data collector is used for collecting the information of the signal lamp in real time. The AT89C51 single chip microcomputer is connected with the congestion index analyzer and the signal lamp data collector to obtain the congestion index of the crossing and the information of the signal lamp. By adopting the traffic data collecting system disclosed by the invention, the traffic data of a crossing where a signal lamp is located can be collected accurately under various weather conditions, and an important basis is provided for information distribution of a local traffic control department.
