Abstract

One of a plurality of cars (17, 18) traveling in a hoistway (10) of an elevator system (9) may be diverted to the hoistway overhead (31) or pit (36) to enable another of the cars to gain access to a floor near or at a terminal floor (11, 14). When such car is at its last stop with doors open, visual (40) and audible (41) indicators present (57, 58) messages to the effect that this is the last stop and passengers should exit. After car doors are closed (66), visual and audible messages (68, 69) relate to the car going to the pit or overhead and that passengers may push any button (to reopen doors). Thereafter, the car moves (75, 76) to the overhead (31) or the pit (36) and presents (82, 83) visual and audible messages to the effect that passengers did not exit at the correct floor and must wait while the other car makes a stop. Once the terminal floor is clear, the diverted car will run (87-89) to that floor, presenting (92, 93) visual and audible messages to the effect that passengers should exit once the doors are open and reenter their service requests.
