"The Roads Must Roll" is a 1940 science fiction short story by American writer Robert A. Heinlein. It was selected for The Science Fiction Hall of Fame, Volume One, 1929–1964 anthology in 1970.[1]
The story is set in the near future, when "roadtowns" (wide rapidly moving passenger platforms similar to moving sidewalks, but reaching speeds of 100 mph) have replaced highways and railways as the dominant transportation method in the United States.
Heinlein's themes are technological change and social cohesion. The fictional social movement he calls "functionalism" (which is unrelated to the real-life sociological theory of the same name), advances the idea that one's status and level of material reward in a society must and should depend on the functions one performs for that society.
