An improved system for elevator control system is disclosed in which the past traffic demand data that have occurred during a plurality of the same predetermined past unit time periods as the current time period are studied so that these past data may be reflected in the group control of the elevator operation. If the data for a day with different traffic demand from a usual value were studied during the study of past traffic demand that occurred in the course of said predetermined unit time periods, the resulting preestimation would be inaccurate. In view hereof, according to the present invention, any traffic volume data that is markedly different from the traffic demand so far encountered is not studied or, alternatively, the data for a day of the week on which the traffic demand is different from the usual value, such as Sunday, is not studied, thus enabling more accurate preestimation of traffic demand for the unit time period beginning with the current time.
