Abstract: A parking area entrance or exit barrier includes a control system which receives inputs from various accessories associated with the operation of the barrier, and which provides control signals to the various accessories of the barrier. One of the accessories includes a sensor attached to the barrier. The sensor senses an accident event, such as contact between the barrier and a vehicle. Whenever an accident event is sensed, the control system creates an accident event log of information concerning the accident event. The accident event log may include video images of the barrier, a position of the barrier, a movement direction and speed of the barrier, and an approximated speed of the vehicle. The control system may also monitor a performance of the various accessories of the barrier and create a performance log relating to any malfunction of the accessories.
