An elevator control system for controlling a plurality of elevator cars arranged for parallel operation for servicing a plurality of floors of a building, in which means are provided so that, in response to origination of a new hall call in addition to hall calls originated and allotted already, a suitable elevator car for servicing this new hall call can be selected and the new hall can be allotted to the selected elevator car to be serviced by this elevator car. In the system, this new hall call is allotted preferentially to one of the elevator cars having an already instructed stopping floor within a predetermined floor range covering a plurality of backward and/or forward floors contiguous to the new hall call originating floor. In this elevator control system, the already instructed stopping floor is evaluated by employing a weight coefficient which is variable depending on the factor such as the position of the already instructed stopping floor either backward or forward relative to the new hall call originating floor, or the relative distance between such floor and the new hall call originating floor, so as to provide improved elevator service.
