It's moving walkway and many other names as in the link in wiki.
Hello,We can always see this in the airport terminals. It can help people walk faster, and it is built on flat surface, not on slope. Does anyone know it's name? In fact, what would be more helpful is if you could help me describe what this is as it would be more helpful. I guess we cannot say this is flat elevator because it does not elevate.Thanks.
