Here we observed emergency evacuation of Station 5 of Tabriz Urban Railroad Organization (TURO) by using Distinct Element Method (DEM). In DEM, analysis can compute the position of each person step by step by solving the equation of motion. 5 cases with different number of people in platform and concourse level are considered and evacuation simulation is done simultaneously for both levels. Density of people near exits and gates is observed by considering control zones in platform and concourse levels. Evacuation time and maximum density on exits are calculated quantitatively for considered cases and the obtained results are discussed. According to simulation results, we can conclude that number of people has great influence in evacuation time and maximum density of people so it is essential that before construction of public buildings such as subway stations, evacuation simulations considering maximum expected number of people in order to meet safety requirements should be done.
