INTRODUCTION as well. All the transport/traffic characteristics around the area This article is risen up from the traffic engineering of Bratislava and its surroundings declare about the study of the D4 and R7 motorway/expressway with a traffic importance of appropriate road infrastructure solutions by forecast for a decision making on the PPP project realization, creating the „Zero – circuit“, constructing the D4 motorway in which was a need for a public procurement in a PPP tender. terms of the strategy of the road network development. These The content of the article is fulfilled in these steps: are: 1. Review of the traffic infrastructure in present time and the Bratislava is the capital and largest city of Slovakia, defined new sections of the project, Bratislava is a source and destination for the car traffic. 2. Actual traffic loads and historic traffic development in the High traffic load on the entrances into the city causing a area of influence from motorways and all state and strong link of the population close to the villages to the regional roads as a part of the traffic model, capital, in which is realized the major part of their job 3. Assessment of the traffic forecast included the opportunities, educational and other activities, comparison of the traffic data from automatic counting the trend of traffic growth is fostered by the resettlement and state traffic census with the base model output, of urban population to rural sites for even higher quality 4. Definition of the urban forecast for the agglomeration of housing, especially in the south-eastern and eastern parts, the city and definition what could be used and why, but also to other parts of Bratislava region, probably some explanation how they will be used for the Bratislava is on the eccentric position in relation to the traffic forecast. whole territory of the State and on the south-western outskirts, near the state borders with Austria and Hungary, 42 International Journal of Advanced Information Science and Technology (IJAIST) ISSN: 2319:2682 Vol.5, No.6, June 2016 DOI:10.15693/ijaist.2016.v5.i6.42-49 for the most part of Bratislava territory is flat terrain, from The D4 motorway is part of the core network of one part of the north-western city, almost up to the middle motorways and expressways in the corridor Bratislava-Jarovce of the cityextends the Little Carpathians Mountains, – Stupava – the State border of the Slovakia and Austria. The practically up to the largest European river - Danube, main goal of the D4 motorway is a detour of the transit traffic which touches the centre of the city on the length (approx. to Austria and Hungary, which in present time goes through 1/3) and divides the city into two parts. the build-up area of the city. In this specific territory markedly helps to the service of the background of the city and relieves Figure 1 – Present road network of the city of Bratislava the villages and the existing road network form transit traffic. The traffic problems grow up on the existing Brno Zilina motorway sections D1 and D2 as well. The transit traffic from Trnava on D1 goes directly through the city on the Port bridge (Pristavny most), and by Vienna route split up the trips to Motorway individual directions. Because of the „insufficiency“ road tunnel construction network in Bratislava, the motorway network is used by inside origin/destination traffic moving from west side to east side and vice versa. This causes extra traffic loads, in particular, in the field before and on the Port Bridge, and on the all connected roads on Bratislava side and through Petrzalka borough (south part of the city) as well. After the completion of the D4 motorway, in prepared stage without the tunnel, the motorway section D2 will be fulfilled the sections on the Lanfranconi bridge and tunnel section Sitina (west side of the city). The total length of the D4 motorway sections is 22,590 km and its scheme is on Fig. 3. Vienna Budapest 2.2. R7 expressway The R7 expressway is part of the core network of The Land Master Plan (LMP) of Bratislava is the motorways in the corridor Bratislava - Dunajská Streda - Nové basic program document, through which the objectives Zámky - Veľký Krtíš - Lučenec. It will be a part of the pursued the role of spatial planning in the territory of the international European roads E 575. The R7 expressway is capital city as well as the development of transport guided through the economic uses territory and the traffic is infrastructure. not directed into urbanized areas. The route of the expressway Bratislava consists of 5 districts and 17 boroughs. begins on Bajkalska Street in the existing interchange The transport system is developed as a radial-orbital system. It “Prievoz” (interchange with Port Bridge) on D1 motorway, is created up of 3 urban rings, from which it is called the “Zero passes through the site Palenisko near the port, crosses the circuit” – outside ring creates by the D4 motorway. Radial Little Danube River, and runs along the western edge of the road system creates these radials: Slovnaft refinery. Then it continues on the interchange “Ketelec” with the D4 motorway. Racianska from the city Pezinok and it is the road II/502, The R7 follows southwest of the village Rovinka and Trnavska formed by the motorway D1 Dunajska Luzna with interchange "Dunajská Luzna" (R7 with Senecka formed by the road I/61, the road I/63) in direction to Samorin. The route is getting into Mostecka formed by the road II/572, the space between the city of Samorin and the municipality of Kvetoslavov. At this point, crosses the road II/503 "Samorin". Samorinska formed by the road I/63 from the Dunajska Then continues north around the settlements Samot, and the Streda, and it will create the R7 Expressway, route passes through the villages gradually Trnavka and Rusovska the road I/2 from the Hungarian border Macov. Finally, it is the route traversed north of the village Viedenska from the border with Austria created by the Blatna na Ostrove and is again close to the road I/63. This D4, section finishes between the villages of Holice and Cechova with connection on road III/06324 and I/63. The total length of Hainburska formed by the road I/2 from Austria, from the R7 sections R7 is 17,380 km. Expressway R7 scheme is Berg shown in Fig. 3.
