PROBLEM TO BE SOLVED: To provide a method for controlling ventilation by recognizing the wind direction and the wind speed, which are closer to the actual conditions, of a whole extended tunnel of a road tunnel of a vertical shaft intensive exhaust ventilation system. SOLUTION: Traffic volume data in each of an up-entrance side area Sa and a down-entrance side area Sb from the tunnel exhaust port 4 in the road tunnel 1b of the vertical shaft intensive exhaust ventilation system are computed, and the wind direction, the wind speed, the amount of generation of pollutant from traveling vehicles, and the traffic ventilation wind pressure for the areas Sa, Sb in the tunnel are recognized individually. By computing a machine ventilation wind pressure on the assumption that a wind pressure effect opening area at the tunnel exhaust port 4 is the tunnel area of each of the areas Sa, Sb, the wind direction and the wind speed in each of the areas Sa, Sb in the tunnel are computed individually.
