Abstract
Each elevator corridor of an elevator system has a transponder beacon disposed near each access to the corridor, each potential passenger, including regular tenants and visitors, carries a responder, such as an RFID responder, so as to provide an indication of entrance into and exit from the elevator corridor. Passengers that are not visitors have a history developed as to the likely travel route of each passenger as the passenger enters the elevator lobby; that is, whether the passenger is likely to take the elevator at this time, or likely to exit the elevator corridor to some other facility. Entered calls can be cancelled if the passenger leaves the lobby, and passenger travel patterns are updated with each passage through the elevator lobby.
