An elevator target floor registration unit, which displays an estimated amount of time until an assigned elevator car arrives, reduces feelings of uneasiness. Various target floor registration units by which a user may register a target floor are installed on respective floors of a building. The target floor registration units are connected to an elevator controller via an interface. The elevator controller: (a) assigns a most suitable elevator car corresponding to a user's target floor registered using the target floor registration unit; (b) computes an expected waiting time for the elevator assigned to arrive at the floor of the aforementioned registration; and (c) sends said pieces of information on the elevator assignment and the expected waiting time to aforementioned target floor registration unit in order to display them.

Destination calls entered by means of buttons (-) are each given a designation unique to the car and pick-up floor for that call and other calls to be serviced therewith, such as a letter (A-E), which is different from any other outstanding calls. Calls can be reassigned among elevators (UL, LL, UR, LR) whether they are in the same or different hoistways (LF, RT). Signs (--) adjacent each hoistway are illuminated to display the designation of any call which is being answered by an elevator car approaching the floor. Thus, passengers are informed when their call is being answered by the signs identifying the call, rather than identifying any particular car. Another embodiment identifies () the hoistway landing doorway () as well as a letter to allow passengers to wait adjacent to the hoistway landing doorway of the car which will serve them.

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.

An elevator system includes a controller that uses one of a plurality of fuzzy logic algorithms for assigning an elevator car to service a passenger request. One example uses a passenger's desired destination as indicated by the passenger service request prior to the passenger entering an elevator car. One example includes multiple fuzzy logic algorithms, each corresponding to a particular relationship between an elevator car's current assignments, a passenger's desired destination, a source landing of the passenger's request, or a combination of them.

A control device for a double-deck elevator system having an upper deck and a lower deck, includes a group control device for assigning the upper and lower decks to respond to car calls from the upper and lower decks and boarding hall calls from a plurality of floors. The control device further includes an assignment control device for determining whether a plurality of the car calls and boarding hall calls can be responded to simultaneously and for directing said group control device to reassign the upper and lower decks to respond to the plurality of car calls and boarding hall calls simultaneously.

An elevator system (,) includes an elevator car (,) supported for vertical movement on a belt (,) having an end fixed to the hoistway (,) and the other end wound about a drum (,) of a drum drive (,). When the belt (,) is wound or unwound about the drum (,), the elevator car (,) is raised or lowered, respectively.
