ABSTRACT:
The detection of traffic demand for elevator cars serving a plurality of floors is related. A device is provided for detecting the latest information on traffic demand based on the number of passengers actually boarding and alighting from cars (herein-after referred to as the "boarding and alighting passengers"). On the basis of the respective floors at which cars are stopped to serve, the direction of travel of the cars, and the number of passengers boarding and alighting from the cars at the respective floors, the number of boarding and alighting passengers by direction is detected for each floor. The detected numbers for the respective floors are totaled to detect the traffic demand at each floor by direction. Further, the total is made for each traffic demand pattern to detect the traffic demand at each floor by traffic demand pattern and by direction. By taking the cumulative total of the totaled numbers of boarding and alighting passengers for all the floors by direction, the total number of boarding and alighting passengers is calculated. The results of these calculations are used to detect various types of information on traffic demand.
