This paper compares the temperature and velocity predicted by Large Eddy Simulation (LES) with those by the experiment, in order to grasp the effectiveness of the smoke flow reproducibility by LES. Tunnel scale characteristics of the smoke flow and the temperature are also examined with the macro evaluation model based on the LES results. It is shown that LES results correspond well with the experimental values, and that the tunnel scale characteristics can be described by the macro model. In addition, Cumulative Thermal Value was used as the thermal index of evacuation safety in the tunnel fire.
