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.
An elevator car traffic demand detecting apparatus for a plurality of elevator cars serving a plurality of floors, comprising a first device for detecting the number of passengers boarding and alighting from each car each time the car serves each floor, a second device for detecting the floors served by the car, a third device for detecting the direction of travel of the car service, a fourth device supplied with at least the three outputs respectively from said first, second and third devices for detecting the number of boarding and alighting passengers by direction for each floor each time the car serves each floor, and a fifth device for accumulating, by floor and by direction, the numbers of boarding and alighting passengers by direction for each floor which are detected by said fourth device each time the car served each floor.
