The ventilation system of Higashiyama tunnel of Nagoya expressway No.2 Higashiyama line is the type which Portal exhaust system was combined with Trans-verse ventilation system. A change in an evacuation environment in the fire by the difference in the ventilation control pattern was evaluated at a stage of a plan by the numerical simulation. However, there were a few fire experiment cases at the actual tunnel of transverse ventilation system, and relative comparative data couldn't be found in it. This paper describes about the fire experiment enforced in Higashiyama tunnel last year.
