Abstract
At a single floor of a building, such as at the lobby, destination calls are entered via a destination call entry device touch pad such as a (12) so that overall system response can be optimized during up-peak service intervals. A maximum number of calls are assigned to each car in order of its priority, or advantageous situation with respect to loading the lobby passengers, and the dispatch interval for each car is individually adjusted. The calls may be assigned to a car prior to its arrival at the lobby, and call assignments are audibly and/or visually displayed by an indicator device (16).
