The moving walkway, also known as a conveyor belt, is an urban mobility solution proposed by Eugène Hénard for the 1900 Exposition Universelle in Paris, which ran from April 14 to November 12, 1900. Although the initial project was not accepted, it was improved by American engineers Silsbee and Schmidt in 1893, allowing for the creation of moving sidewalks with varied speeds. This historical photograph, taken by the Atelier des frères Neurdein, shows the 1900 Exposition Universelle in Paris, where the moving sidewalk was in operation. Installed 7 meters high on a metal viaduct, it extended nearly 4 kilometers, providing a fast alternative for pedestrians. Earlier tests took place in Berlin in 1896 and in Saint-Ouen in 1899, increasing interest in this mode of transport. The historical context is marked by the technological rise at the end of the 19th century, during which urban planning and public transport were undergoing huge changes. Finally, the project by Blot, Guyenet, and Mocomble was chosen, transporting nearly 7 million visitors and integrating nine elevated stations, facilitating access and contributing to smooth pedestrian flow.
