    Abstract: A passenger waiting assessment system including: a sensor; and a dispatcher including: a processor; and a memory including computer-executable instructions that, when executed by the processor, cause the processor to perform operations, the operations including: receiving a number of elevator calls; assigning the elevator calls to an elevator car of a first elevator system; moving the elevator car of the first elevator system to a landing; detecting, using the sensor, a number of individuals waiting to use the elevator car of the first elevator system; and stopping assignment of any further elevator calls to the elevator car of the first elevator system when the number of individuals is greater than a threshold value.

    Abstract: An elevator system having a hoistway having a bottom landing with landing doors. An elevator car is in the hoistway, and a safety chain is coupled to the car and is in an open-state to stop the car and otherwise in an intact-state. A first sensor wirelessly transmits a first signal when the car is at the bottom landing, and a second sensor transmits a second signal when the doors are open. The system includes a control circuit including a first control element that receives the first signal indicating the car is at the bottom landing and a second control element that receives the second signal indicating the landing doors are open, and the control circuit changes state upon receipt of the signals, and the safety chain transitions to the open-state from the intact state when the control circuit changes state.
