The canal structured road is built half underground, and it consists of opening and close duct. In the canal structured road with narrow openings, it turned out in the former work that the breathing effect for ventilation is suppressed. Then, the phenomenon in which generating the mass flow by the inhalation and the exhalation by setting up the obstacle board in closed duct, and increasing the breath value is quantitatively evaluated by the numerical analysis. A continuous running of the cars is imitated by the sliding mesh function by using 3D numerical analysis as a method for analysis. As a result, Inlet flow is decreased by 29.5% by setting up obstacle boards in closed duct, and the breathing value has increased by 5.47%. Moreover, it was observed that the mass flow was generated in the opening.
