The invention discloses a pedestrian crossing control system which comprises an indication component, a gate closing and opening component, an information processing component, a monitoring componentand an information feedback component. The indication component comprises a traffic light electrically connected with an external power source. The gate closing and opening component comprises an automatic lifting column, the traffic light is wirelessly connected with the automatic lifting column, and the automatic lifting column comprises an automatic lifting column body, a first inverter, a supporting board, a flexible solar panel, an air cylinder, a protection shell, a first storage battery and LED lamps. When a yellow light of a pedestrian signal indicator light flickers, the system sendsa voice prompt, after the yellow light of the pedestrian signal indicator light flickers and when a red light is turned on, the lifting column automatically ascends to the position, a pedestrian passageway is cut off, pedestrians are forbidden to pass, the pedestrian crossing control system and the pedestrian traffic light of an intersection are in linkage, the situation that the pedestrians run the red light is effectively controlled, it is guaranteed that the pedestrians safely pass a road, and traffic safety accidents are greatly reduced.
