Emergency evacuation in metro stations, tunnels, and multi-level transportation facilities is analyzed by evaluating user movements, evacuation routes, density distributions, and exit capacities together. In such structures, passenger density, spatial constraints, and wayfinding systems have a direct impact on evacuation performance.

Within the scope of the simulation studies, pedestrian flows, bottleneck points, density levels on intermediate floors and exit areas, and total evacuation times are examined under different emergency scenarios. Scenario-based evaluations enable user behavior and evacuation capacity within the facility to be numerically assessed during an emergency. Based on the results obtained, evacuation routes, wayfinding strategies, and operational scenarios can be tested to develop safer and more effective evacuation plans.

Fire and smoke spread simulations are used to analyze emergency scenarios in metro stations, tunnels, car parks, industrial facilities, and large-scale enclosed spaces through CFD-based modelling. Within the scope of these studies, critical safety parameters such as fire source, smoke movement, temperature distribution, visibility distance, and air velocity are evaluated.

Different smoke control strategies, including physical barriers, smoke curtains, fire curtains, platform screen doors, evacuation routes, and fan systems, are examined under various scenarios. In this way, smoke spread behavior during a fire, its effects on passenger or user safety, and the performance of existing systems can be numerically assessed.

These analyses are used as a decision-support tool to verify design decisions, compare alternative scenarios, and develop fire safety strategies more effectively.
