The document discusses different types of transportation systems used in high-rise buildings. It describes lifts (elevators), escalators, and moving walkways. Elevators efficiently move people between floors and can travel at speeds up to 2,000 feet per minute. Escalators are moving staircases that carry people between floors, typically at speeds of 1.5 feet per second. Moving walkways transport people horizontally or at an incline over short distances, usually at speeds of 90 to 120 feet per minute. The document outlines safety procedures for using each type of transportation system.
