https://doi.org/10.4467/2353737XCT.18.049.8344Problems with parking individual cars, particularly in urban areas, were already experienced by the inhabitants of developed countries in the interwar period. These problems continue to appear, as the number of cars increases and there are fewer and fewer parking spaces. Therefore, solutions are sought after to ensure the largest possible number of parking spaces with the smallest occupied area, especially in large agglomerations of highly developed countries. The article presents one of the possible solutions – rotary car parks (The Rotary Automated Car Parking System; RACPS). The research results reffered to in the article are the effect of works conducted at the Faculty of Mechanical Engineering of the Cracow University of Technology in the field of modelling and optimisation of a rotary car park [5, 6, 8].
