PARKING: RESERVOIR SIZES AT CAR PARK EXITS

CARS LEAVING A CAR PARK OFTEN HAVE TO PASS THROUGH AN EXIT GATE BEFORE JOINING THE STREET NETWORK AT A T-JUNCTION. CONSIDERED IN ISOLATION THE MAXIMUM RATE OF FLOW THROUGH AN EXIT GATE IS DETERMINED BY THE PHYSICAL DESIGN AND BY THE PAYMENT SYSTEM USED, BUT THE DISCHARGE RATE OF THE SYSTEM DEPENDS ALSO UPON THE SIZE OF THE RESERVOIR BETWEEN THE GATE AND THE JUNCTION, AS WELL AS THE FLOW ON THE MAIN ROAD. A COMPUTER SIMULATION WAS DEVELOPED WHICH WAS CALIBRATED AGAINST EXPERIMENTS CONDUCTED ON THE PUBLIC ROADS. THE RESULTS FROM THE SIMULATION HAVE BEEN USED TO ESTABLISH THE RELATIONSHIP BETWEEN THE FLOW OF CARS THROUGH THE EXIT GATE AND (A) THE GATE SERVICE CAPACITY, (B) THE TRAFFIC FLOW ON THE MAIN ROAD AND (C) THE RESERVOIR SIZE. THE RESULTS MAY BE USED BY CAR PARK DESIGNERS TO DETERMINE SUITABLE RESERVOIR SIZES IN TERMS OF GATE SERVICE CAPACITY AND MAIN-ROAD FLOW. /AUTHOR/
