Large hospital grounds when placed in or near the city centres need the efficient parking system, which regulates traffic and parking in these areas. The parking system allows the operator to control the entry and exit allowance for different groups of drivers, hospital personel, patients and suppliers without any limitation for ambulances and fire engines, who really need the unrestricted access into the area. The advanced and powerfull system for ticket validation allows to differentiate the rates for patients, visitors and other drivers of parking vehicles, which makes the system socially acceptable.
