The invention discloses an intersection timing signal control multi-period automatic division method. The method comprises the following steps: processing intersection traffic flow data; calculating the traffic flow of the key lane in the lane group; discretizing the key lane total flow sequence into a character coding sequence; carrying out sampling clustering on the character coding sequence; and performing signal control time interval segmentation and adjustment based on the clustering tag sequence. According to the method, the full-day lane-level five-minute flow of the intersection is checked and repaired, the key lane total flow of the intersection is calculated according to channelization information and selectable constraints, control period division is performed based on the key lane total flow, and a signal timing scheme is more reasonable.
