Emergency evacuation models in subway service systems: An application on Izmir (Turkey) subway system

Increasing population in crowded cities causes transportation problems. public transportation is an effective solution for the crowded traffic. subway is a fast and productive alternative for public transportation so it is a highly preferable choice in others. it is hard to evacuate people in subway station during a disaster in carriages, on subway line or in subway stations because subway systems are often located underground, a lot people use it at the same time and enter-exit gates are controlled by turnstiles. it is crucially important to know the evacuation time of people from subway. in this paper, konak station, one of the most crowded stations of izmir subway system is analyzed by emergency evacuation models. the evacuation process is simulated by simulex software. the emergency evacuation problem is modeled in three different scenarios. solution offers are developed for them.
