Abstract

An elevator system utilizes a destination entry control technique and delays indicating which car is assigned to a request to allow an individual to arrive near an elevator lobby. An elevator group assignment is made responsive to a destination request. An indication regarding the group assignment is provided to a passenger within a first time from the receipt of the request. A second indication regarding a car assigned to carry that passenger to the desired destination is provided at a second, later time from the request. Separating out the group assignment indication and the car assignment indication is accomplished in one example by providing separate interfaces at different locations within a building.
