Glidepath
A structure found in many large cities, to ease the congestion in pedestrian areas. A glidepath is a walkway with a relatively fast moving surface, often some kind of belt system. Alternatively, there are paths which have complex air pumps, so that pedestrians can skate on a cushion of super-dense liquid. While they can be dangerous - as most such systems rely on the pressure of crowds to prevent people falling over - this is considerably more efficient than requiring people to board a vehicle or dropbox every time they wish to travel to a different city district.
Glidepaths are common on every class 5 world, except for Magellan where only a few are installed within privately managed retail parks or business districts.
