Moving pavement

A moving walkway or moving sidewalk (American English), known in British English as a travelator,travolator, or travellator, 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.

The first moving walkway debuted at the World's Columbian Exposition of 1893, in Chicago, Illinois, in the United States. It had two different divisions: one where passengers were seated, and one where riders could stand or walk. It ran in a loop down the length of a lakefront pier to a casino. Six years later a moving walkway was also presented to the public at the Paris Exposition Universelle in 1900. The walkway consisted of three elevated platforms, the first was stationary, the second moved at a moderate speed, and the third at about six miles per hour. These demonstrations likely served as inspiration for some of H. G. Wells' settings mentioned in the "Science Fiction" section below.

The Beeler Organization, a New York City consulting firm, proposed a Continuous Transit System with Sub-Surface Moving Platforms for Atlanta in 1924, with a design roughly similar to the Paris Exposition system. The proposed drive system used a linear induction motor. The system was not constructed.

The first commercial moving walkway in the United States was installed in 1954 in Jersey City, NJ, inside the Hudson & Manhattan Railroad Erie station) at the Pavonia Terminal. Named the "Speedwalk" and built by Goodyear, it was 277 ft (84.5 m) long and moved up a 10 percent grade at a speed of 1.5 mph (2.4 km/h). The walkway was removed a few years later when traffic patterns at the station changed.
