DESIGN ISSUES OF GARAGES FOR PASSENGER CARS OF VARIOUS CLASSES

The article addresses the issue of determining parking space dimensions in the design of garages for passenger cars of different classes, from extra-small to large. The influence of the parking space’s location relative to other vehicles and the structural elements of the garage on the size of the parking space is analyzed. In recent years, the construction of built-in and attached ramp-type parking garages has significantly increased with the construction of new residential complexes and public buildings or during the reconstruction of existing ones. Although designers rely on existing regulatory acts, documents, and guidelines when designing these garages, and experts evaluate the design solutions, drivers of medium and large cars often experience difficulties when entering and exiting garages via circular ramps and parking in available spaces. Amendment No. 3 to DBN B.2.3- 15:2007 expanded the regulatory parameters for the width of the driving lanes and the radius of curved ramps, but the requirements for the dimensions of parking spaces remained unchanged. Based on this, a classification of parking space types in garages is proposed, depending on their location relative to other vehicles and structural elements, taking into account appropriate protective zones. A conclusion is drawn about the need to amend DBN B.2.3-15:2007 “Transportation Facilities. Parking Lots and Garages for Passenger Cars” regarding the regulation of parking space dimensions in garages for passenger cars.
