A method for controlling an elevator system comprises obtaining images of the inside of an elevator car, detecting passengers in the images, creating graphic passenger models of the detected passengers from the images and determining the number of passengers who may additionally board the elevator car using the passenger models. The passenger models may reflect the actual size of the passengers.

Method for controlling an elevator system

An elevator motion alert system is configured to alert a person of an object moving in at least one hoistway of an elevator system. The elevator motion alert system includes a sensor configured to detect object motion. A transmitter of the elevator motion alert system is carried by the object and is configured to transmit a pressure wave at a pre-defined frequency upon movement of the object. An electronic device of the elevator motion alert system is configured to receive and process the pressure wave for alerting the person of object movement.
