The invention relates to artificial intelligence, and provides a signalized intersection analysis method and equipment. The method comprises the following steps: acquiring a vehicle passing time sequence of each preset lane of a signalized intersection in each preset time period; according to the vehicle passing time sequence, calculating a vehicle head time distance sequence of each preset lane of the signalized intersection in each preset time period; acquiring signal timing data of each preset lane of the signalized intersection in each preset time period; correcting and matching the signaltiming data according to the vehicle passing time sequence; identifying a saturated vehicle head time interval sequence of each preset lane of the signalized intersection in each preset time period according to the vehicle head time interval sequence; removing abnormal data in the saturated headway sequence according to the corrected and matched signal timing data to obtain a target saturated headway sequence; and calculating the traffic capacity of the signalized intersection according to the target saturated headway sequence. According to the invention, the accuracy of signal intersection traffic capacity analysis can be improved.
