There is provided an emergency terminal stopping system for an elevator system, the emergency terminal stopping system comprising: a sensor configured to determine data related to the motion of an elevator car moving within an elevator hoistway; at least one elevator brake configured to halt the motion of the elevator car; at least one elevator safety gear device provided on the elevator car; and at least one buffer provided at a lower portion of the hoistway. The controller is configured to receive data from the sensor relating to the motion of the elevator car; monitor a current speed of the elevator car with respect to a distance from a terminal limit of normal elevator car travel; detect an abnormal speed of the elevator car; activate the at least one elevator brake in response to a detected abnormal speed; monitor a current acceleration of the elevator car following activation of the main elevator brake; detect an abnormal acceleration of the elevator car; and activate the elevator safety gear device in response to a detected abnormal acceleration.
