The "Metro Safety Evacuation Specification" stipulates that the section safety evacuation can be carried out by emergency evacuation platform and track bed evacuation. The evacuation path must ensure continuity, barrier-free and flatness. When the train cannot travel to the next station in the section, passengers can evacuate to the safe area on foot. When an emergency occurs, the subway needs to stop in the tunnel urgently, and passengers need to be evacuated to the track bed for transfer quickly. The side door of the subway is about 0.8 wide from the aisle wall on the side of the subway. The floor of the subway car is about 1.5 meters above the track bed. Passengers need to overcome the height difference of nearly 1.5 meters from the ground in the car to the track bed. There is a great risk factor, and some equipment is needed to help passengers overcome this height difference.
