Although in many questionnaires (Markovic et al., 2012) individual quality factors are substantively combined to express characteristics of several factors in a single, uniform quality factor (e.g., attractiveness of car parks and surrounding areas), in our study we have exclusively used one quality characteristic for the description of each quality factor (see Tab.
