Moving stairways are also known as escalators, travolators, and inclined moving walkways. The term escalator is commonly used in the United States, while travolator is more commonly used in Europe. Inclined moving walkway is a more descriptive term that emphasizes the upward slope of the pathway. There are different types of moving stairways, including spiral escalators, inclined elevators, and horizontal moving walkways. These devices are commonly used in transportation hubs such as airports, train stations, and shopping centers to move people efficiently and rapidly. Regardless of the type and name, moving stairways are important innovations that have changed the way people move in public spaces.
