I was wondering what if there’s a large space in the middle of the airport where I want to build a terminal which is surrounded by taxiways or the distance from a terminal to a terminal is far? It’s a fact that the passengers could walk that far. However, the passengers couldn’t take a short period of time to walk that far and cross every service road including runway and taxiway I’m sure everyone would say that the plane would have already departed before the passengers arrive at the boarding gate. Also, passengers can’t walk through taxiways and runways. I think there should be transports within the airport.
Here are some of the In-Terminal transports I could think of:
Bus - They can travel through service road (or other roads if available). They may worsen traffic along the service road but much better than a bunch of people blocking the service road.
Underground transit - They are fast and won’t worsen traffic as it is underground.
Please also help support us as we all love and want to support this game. Thank you!
