PROBLEM TO BE SOLVED: To provide a tunnel ventilation control device which does not reflect erroneous input data on ventilation control by determining that the input data is abnormal when erroneous traffic data and ventilation state data are input without input of a failure signal, to thereby prevent increase in unnecessary power consumption caused by excessive operation of ventilators and danger due to too little operation of the ventilators. SOLUTION: According to the tunnel ventilation control device, it is determined by a traffic data normality determining means 17 whether or not the input traffic data indicates impossible conditions that cannot arise in normal times. When it is determined that the input data is abnormal, the data is not delivered to a control means 18, and therefore the data is not reflected on control of the ventilators 12.
