A moving walkway (British English) or moving sidewalk (American English) (colloquially sometimes travelator,horizontal escalator,walkalator,autowalk,movator,people mover) is a slow moving conveyor mechanism that transports people,across a horizontal or inclined plane,over a short to medium distance.Moving walkways can be used by standing or walking on them.They are often installed in pairs,one for each direction.
An escalator is a moving staircase – a conveyor transport device for carrying people between floors of a building.The device consists of a motor-driven chain of individual,linked steps that move up or down on tracks,allowing the step treads to remain horizontal.
