comparing the predicted crowd size with a second crowd size threshold if the predicted crowd size exceeds the first crowd size threshold, the second crowd size threshold being greater than the first crowd size threshold;
generating a crowd signal for the predetermined floor if the crowd size exceeds the first crowd size threshold;
receiving a hall call signal for the predetermined floor;
assigning at least three elevator cars to be predetermined floor responsive to the hall call signal only after said crowd signal generating step and only if the predicted crowd size is greater than the first crowd size threshold and the second crowd size threshold;
monitoring a number of passengers collected by one of the at least three elevator cars at the predetermined floor, and then canceling the assignment of the at least second and third elevator cars to the predetermined floor if the number of passengers collected at the predetermined floor by the one of the elevator cars is at least equal to 100% of a full capacity of the one car.
