Abstract

An elevator traffic control technique includes destination grouping that is selectively implemented during selected traffic condition. One example includes determining when up peak traffic conditions exist. If so, the passenger-to-car assignments are grouped based upon the passengers' desired destinations, which are determined before the passengers enter elevator cars, Arranging sectors responsive to current traffic conditions in one example is based upon elevator passenger traffic patterns over the most recent five minutes.
