The invention discloses a pedestrian and non-motor vehicle equal-height common-board road intersection and a traffic control method. The road intersection comprises four roads whose join part is of a cross structure, each road includes a pedestrian passage and a motor vehicle passage, and an isolation belt is arranged between the pedestrian passage and the motor vehicle passage; each two adjacent pedestrian passages are connected into a pedestrian sampling area with the same height as the corresponding motor vehicle passage, the ends of each isolation belt are both provided with pedestrian signal lights, and the states of the pedestrian signals are switched by the pedestrian signal lights according to the number of pedestrians and/or non-motorized vehicles in the pedestrian sampling area; each pedestrian passage includes a sidewalk and a non-motorized vehicle passage, and a gentle slope is arranged between the non-motorized vehicle passage and the corresponding pedestrian sampling area; a non-motorized vehicle crossing street is arranged at each motor vehicle passage near the end of the cross structure. The safety and order of the intersection are improved by 'pedestrian and non-motor vehicle equal height', i.e., the same height for the pedestrians and non-motorized vehicles.
