An elevator supervision system has a microcomputer type car control connected to a load sensor for sensing a load on an associated elevator car, a microcomputer type group supervision device connected to floor pushbuttons and a clock, and a microcomputer type statistical device connected in two ways to the group supervision device which is connected in two way to the car controls, the statistical device setting a starting and an ending time of a crowded traffic pattern of the elevator cars on every day and recording them for past M days and calculating their mean values and dispersions, the group supervision device receiving data from the statistical device to cause the car controls to control the operation of the cars through associated driving controls and hoist motors.
