A model of the dimensioning of the number of service places at parking lot entrances by using the queuing theory

The issue of the optimal management of the traffic flow and the ensuring of an adequate number of parking spaces is present in the majority of highly developed urban areas of the European Union, including the Republic of Croatia. The formation of an adequate raster of the transport network, conditioned by the historical and existing buildings and areas is an extremely challenging task. Similarly, ensuring an adequate availability of free parking capacities in times of rush hours in the very centres of urban areas is also very demanding. However, what often occurs, even when adequate parking capacities are ensured, is a halt on the input and output terminals of parking lots and garage facilities that are derived by a disproportion of their capacities and traffic needs at a specific time. Precisely for that reason, this paper presents a potential model for determining of an optimal number of input service places (terminals) by using the queuing theory.
