Propusna moć i razina usluge na autocesti A1

Dobra prometna povezanost je vrlo važan faktor u Republici Hrvatskoj jer pridonosi samom razvoju države te zbog povoljnog položaja Hrvatske utječe na razvoj prometnih puteva s drugim europskim zemljama. Razvoj prometne mreže u Hrvatskoj seže daleko u povijest te uključuje velik broj prometnica. Među njima se nalazi i autocesta A1 koja spaja sjever i jug Hrvatske od Zagreba do Splita a čija ukupna dužina iznosi 380 km. Da bi promet bio što brži, jednostavniji i sigurniji cesta mogla udovoljiti uvjetima prometa, mora imati vrlo dobru propusnu moć ceste, razinu usluge ceste i prijevoznu sposobnost. Kapacitet ili propusna moć prometnice je mjera njene sposobnosti za prihvat toka vozila u kretanju, dok je razina usluge je kvalitativna mjera koja se sastoji od brojnih elemenata, kao što su: brzina vožnje, vrijeme putovanja, sloboda manevriranja, prekidi u prometu, udobnost vožnje, sigurnost vožnje i troškovi iskoristivosti vozila. U ovom radu predstavljen je kapacitet i razina usluge na A1 autocesti.Well traffic connections are very important factors in Republic of Croatia because it contributes to the development of the country. Also because of its favorable position affects the development of transport routes and corridors to other European countries. The development of transport network in Croatia goes way back in history and includes a large number of roads. Among them is the A1 motorway that connects croatian north and south, from Zagreb to Split and whose total length is 380 km. For the faster, easier and safer roads, there must be very good road capacity, the level of service and transport capability. The road capacity is a measure of its ability to accept the flow of vehicles in motion, while the level of service is a qualitative measure that consists of many elements, such as travel speed, travel time, freedom to maneuver, traffic interruptions, ride comfort, driving safety and cost efficiency of the vehicle. This paper introduces the capacity and level of service on the A1 motorway
