  • Patent number: 5389921
    Abstract: A parking lot traffic control and fee collection system is disclosed for use in stadium type parking lots. A vehicle counter installed in a portable traffic pylon is provided at the entry point for each entrance lane of the parking lot for marking the station of the parking attendant. The vehicle counter is installed in a tamper-proof arrangement and the cumulative count of vehicles is presented on a display device which is viewable without opening the enclosure provided by the pylon. A parking supervisor may read the cumulative count at any time and pick-up the receipts from the parking attendant during or at the completion of the parking process. The amount of the receipts collected is compared with the reading on the display device and discrepancies are noted by the supervisor. The vehicle counter is provided with a tamper-proof reset switch.
