In the first part of the specialist diploma thesis states the issue of traffic at standstill and how to come up with the optimum number of parking spaces. Further, the dimensions of the vehicle concerned and the parking modes and the type raster are provided with the advantages and disadvantages. After the theoretical processing of standstill traffic follows the practical part of the graduate thesis, which is the conceptual solution of the access control of a parking lot. The practical part of the work consists of a technical description, a budget and a draft. On the existing base, considering the increased parking needs that are generated by the surrounding facilities and the factors of attracting traffic. The conceptual solution of the access control parking lot was created. The access control is solved by setting the bumper at the entrance and exit and the charge will be made automatically, in accordance with the time, when leaving the parking lot. For a successful dimensioning of the parking lot, minimum parking space and maneuvering space dependent on the type raster must be known.
