Well we haven’t made any final decision here but I think we’re leaning to enforce that jetways either connect to the second or third floor. I can’t see how they would “fit” towards a ground floor connection as vehicles would have to “run through them”. Although we do operate in a 2D space so anything is possible, we’ll have to do some more thinking here.
Yeah, I agree, I think we will push to get one-way doors in for the multiple floor update. Escalators and stairways will support designating what direction they operate in so this will be one way to control the flow, but I agree we need doors.
Are there any real-world examples of this? I don’t think I’ve ever passed through a jet-way like that but I’m not sure.
Yes, conveyor belt and roads will be both be possible to be built on negative floor heights, with or without a terminal foundation beneath. The same goes for positive floor heights, at least for conveyor belt (we haven’t decided with roads yet).
