What is a common feature of modern elevator doors to enhance passenger safety?

A common feature of modern elevator doors designed to enhance passenger safety is the sliding mechanism equipped with safety sensors. This innovation ensures that the doors can detect the presence of passengers or obstacles in their path, preventing accidental closures that could cause injury. These sensors contribute significantly to overall safety by stopping the door from closing if something is detected, promoting a safer boarding and alighting experience.

While heated panels, transparent glass, and automatic locking mechanisms may have their own benefits, they do not directly enhance the safety aspect related to door operation as effectively as the integration of safety sensors with a sliding mechanism. These features primarily focus on aesthetics or convenience rather than immediate safety in the critical moments when passengers are entering or exiting the elevator.
