The Jetsons had moving walkways that took people from place to place efficiently, but even though this wasn’t really a science fiction invention, having been introduced at the World’s Fair in 1900, the technology wasn’t put to general use until 1958, when they were introduced in Airports.
Various other science fiction depictions of moving walkways have appeared in science fiction, from H.G. Wells’ When the Sleeper Wakes to Robert A. Heinlen’s The Roads Must Roll, although in these imaginations, the moving walkways are massive transportation systems instead of a slightly faster form of ambulation.
