Abstract
Factors (IFL, UPK, DPK) indicative of the relative need for an elevator system to be operating in off-peak, up-peak and down-peak modes, respectively, are compared and if the relative need for up-peak is greater than for off-peak or down-peak, the ratio of up-peak need to total need is utilized to assign a proportionate number of elevator cars to up-peak service. Cars are chosen for up-peak service based upon the estimated relative speed with which the cars will be able to return to the lobby. The details of one embodiment include determining interfloor traffic by examining expected destinations of passengers estimated to be waiting behind hall calls and examining the lobby and non-lobby car calls which are registered.
