Claim:
1. An elevator control device in a one-shaft multicar system elevator wherein a plurality of cars are disposed in one shaft so as to ascend and descend freely, comprising: collision prediction means which predicts occurrence of a collision of cars against each other in the same shaft in the case where a predetermined collision prediction implementation condition is held; waiting-with-door-open determination means which determines whether or not a car is caused to be on standby with a door thereof kept open in the case where the collision prediction means predicts the occurrence of the collision of cars against each other in the same shaft; waiting-with-door-open floor determination means which determines a waiting-with-door-open floor of a car in the case where the waiting-with-door-open determination means determines that the car is caused to be on standby with the door thereof kept open; and control means which causes at least either of the cars, for which the occurrence of the collision is predicted, to be on standby with the door thereof kept open at the waiting-with-door-open floor determined by the waiting-with-door-open determination means, wherein the waiting-with-door-open floor determination means determines, from a past use condition, a floor for which the possibility of the occurrence of boarding or alighting of passengers is high as the waiting-with-door-open floor.
