Oko velikih gradova grade se obilaznice čija je namjena rasteretiti urbanu cestovnu mrežu unutar grada. Takve obilaznice se najčešće svode na urbane autoceste s većim brojem ulaznih i izlaznih rampi. Mjesta gdje se nalaze ulazne i izlazne rampe sklona su pojavljivanju prometnih zastoja. Njihovo pojavljivanje se može smanjiti ili u potpunosti spriječiti prikladnim upravljanjem ograničenjem brzine vozila glavnog toka urbane autoceste. U radu su opisani problemi upravljanja prometom na urbanim autocestama, objašnjeni su pristupi za upravljanje ograničenjem brzine, analizirane su mogućnosti primjene logičkog stabla odlučivanja za upravljanje promjenjivim ograničenjem brzine, izrađen je model dionice urbane autoceste i iskorišteni su postojeći prometni podaci za simulaciju modelirane dionice autoceste uz korištenje simulatora VISSIM.

Bypasses are being built around big cities to disburden the urban road network within the city. Such bypasses are usually confined as urban motorways with a large number of entry and exit ramps. Traffic jams are prone to occur in places where the entry and exit ramps are. Occurrence of traffic jams can be reduced or completely prevented by the appropriate use of vehicle speed limit control on the main road of the urban motorway. In this thesis, problems of traffic management on urban motorways are discussed, approaches for speed limit control are explained, the possibilities of applying the decision logic tree for variable speed limit control are analyzed, a model of an urban motorway stretch was made and the existing traffic data were used for simulation of the modeled motorway section using the VISSIM simulator.
