Mathematical modelling of the spatial efficiency of car parks

Abstract

Abstract One of the major urban concerns is the lack of parking places. The most appropriate indicator for assessing the spatial efficiency of the car parks is the unit surface. The largest space-saving resources to improve spatial efficiency belong to the large car parks in the distinct situations: for employees of a large company or for hypermarket customers. As a result, a mathematical model for access to the parking place by means of a single steering manoeuvre has been constructed, having the angle of inclination of the parking spaces as variable and the 95% percentiles corresponding to the overall current dimensions of the cars as parameters. In the case of customer parking, it was considered that it is necessary for the customers to have access to the trunk to pick up the purchased items from the shopping cart, so a specific arrangement of the vehicles on the parking places is required. The results confirmed the superiority, from the point of view of spatial efficiency, of the angled car parks as compared to the rectangular car parks. For the car parks angled at 45° - 60° it has been demonstrated that increases of more than 10% over rectangular parking spaces are achieved.
