Structure of Nanjing subway station hall
The entrance area refers to the area after passengers enter the subway station, which usually includes the security check passage, entrance gate and waiting area. Passengers need to complete the security check through the security check channel, then verify their boarding documents through the entrance gate, and finally enter the waiting area to wait for the train to arrive.
Platform area is the area where passengers ride, which is usually divided into two types: uplink platform and downlink platform. On the subway platform, passengers can wait for the bus. On the platform, there are usually boarding signs, train information display screens and seats for passengers to rest and wait.
The exit area refers to the area after passengers leave the subway station, including exit gates and exit passages. Passengers need to verify their boarding credentials through the exit gate and leave the subway station through the exit passage.
It should be noted that there may be some differences in the hall structure of different subway stations, which may include the design style of the hall, the location and number of entrances and exits, etc. In addition, the Nanjing subway system is constantly being updated and improved, so there may be a new station hall structure.
