According to an embodiment, a method to communicate with a passenger in a car within a transportation system includes receiving an alarm signal from the car, receiving at least one operation parameter from the car, analyzing the at least one operation parameter corresponding to the alarm signal from the car, determining an alarm condition in response to the at least one operation parameter and the alarm signal, and initiating a video session via a video system in response to the alarm signal.

The method of performing maintenance of an elevator is performed by unlocking and opening a landing door at a lowermost landing manually, activating a first stop button in the shaft, whereby a safety circuit of the elevator is opened so that operation of the car is completely prevented, entering into the shaft, closing the landing door, climbing down from the lowermost landing to the pit, turning a drive switch in a maintenance control unit positioned in the pit into a maintenance drive mode, whereby the first stop button is by-passed so that the car can be driven from the maintenance control unit upwards and downwards in the shaft.

Provided is an elevator control device capable of calling attention to contact between a user and an autonomous moving body in an elevator shared by the user and the autonomous moving body. The elevator control device includes an elevator notification control unit configured to causes, based on a call for an elevator from an autonomous moving body, equipment provided in a hall of the elevator of a floor on which the autonomous moving body is present or equipment provided in a car of the elevator to provide notification of information indicating that the autonomous moving body boards or disembarks from the car.

A method of operating an elevator system is provided and includes recognizing that brakes of an elevator car fail to drop upon brake power being removed, temporarily hovering the elevator car in place to allow the elevator car to be emptied, controllably moving the elevator car in a direction of imbalance, which is defined in terms of relative weights of the elevator car and a counter-weight and torque applied to the elevator car for driving the elevator car upwardly or downwardly, to either a top or a bottom of a hoistway and confirming that the brakes are failing to drop or provide sufficient holding torque.
