PROBLEM TO BE SOLVED: To provide a tunnel ventilation control device that performs ventilation more efficiently.SOLUTION: A tunnel ventilation control device includes: an air capacity setting part which sets air capacity of ventilation facilities for ventilating a tunnel; a production amount calculation part which calculates production amounts of harmful substance at a main part and a branch part based upon a prediction result of traffic volume and a prediction result of an average speed respectively; a leakage amount calculation part which calculates leakage amounts of harmful substance from a pit head of the main part and a pit head of the branch part respectively based upon measured values of air velocities of the main part and branch part and the production amounts of harmful substance at the main part and branch part; a leakage amount target value generation part which generates a target value of a leakage amount in every unit time based upon an allowable value of the leakage amount; and a control part which sets the air capacity of the air capacity setting part based upon the target value of the leakage amount in every unit time and the leakage amount calculated by the leakage amount calculation part. |
