Vienna holds a key position in the Central European transport network and air transportation. In 1994, the inner-city public transport carried 506.3 million passengers with its 35 tramway- and 5 underground railway lines (a total of 1412 railcars and carriages, 237km overall length, 759km service length). 75 motor-bus lines (516 coaches, 617km service length) were used by 120.4 million passengers in 1994. In addition, in the same year 68 motor-bus lines of postal administration and Austrian National Railways starting from Vienna carried 24.2 million people. In 1992, the railway (passenger and goods transportation) commanded a service length of 178km (32 railway stations, 8.9 million sold tickets). For short-distance traffic, the high-speed railway makes accessible Vienna's surrounding area and the region in the east and is principal carrier of the daily commuter traffic (around 180,000 commuters per day). In 1984, the public transport network for the eastern region (Verkehrsverbund Ostregion) was established: the core area comprises the urban area of Vienna, large parts of Lower Austria and a northerly section of the Burgenland.
All of Vienna's railway stations were destroyed or heavily damaged by bombs during the Second World War, the most important were re-erect and redesigned. The old Westbahnhof was replaced by a new building in 1951 and in 1993/94 a reorganisation took place in the course of the involvement of the U3 and the rearrangement of the Europaplatz. 1976-80 saw the covering of the Franz-Josefs-Bahnhof; the West- and the Südbahnhof (which incorporates the former Ostbahnhof) manage the principal and long-distance traffic; the Franz-Josefs-Bahnhof as well as the railway stations Wien-Nord/Praterstern and Wien-Mitte are of importance for domestic traffic.
Vienna's road network is about 2800km long, 680km of which are streets with special relevance for traffic (motorways, main roads, high streets), on which 85% of Vienna's road performance is generated (14.4 million motor vehicle-km/day). At the end of 1995, the cycle path network incorporated 545km.
The city area has 5 viaducts and 2 railway bridges over the Danube: Nordbrücke (part of the Wiener Nordeinfahrt), Floridsdorfer, Nordbahn-, Brigittenauer, Reichs- and Praterbrücke (emerged in the course of the construction of the south-east bypass, the Südosttangente A 20) as well as the Stadlauer Ostbahnbrücke. 23 bridges and foot-bridges cross the Danube channel, among them the 800m long Gärtelbrücke which was built from 1962-1964 and the Erdberger Brücke, developed in the course of the construction of the Südosttangente from 1969-1971.
The number of motorcars per 1000 resident has risen from 94 in 1961 to 434 in 1995. In 1995 there were 710,827 motorcars in Vienna, the parking space situation in the densely built up urban area is accordingly challenging. The southern by-pass (B 301), an important communication road between A 2 and A 4, is supposed to relieve Viennese residential areas and make accessible important locations such as the Donauhafen Albern and the Güter-Terminal Metzger-Werke.
The shipping traffic on the Danube declined heavily after the world wars. A fresh increase in Danube shipping and freight volume is expected following the political and economic opening of Eastern Europe and the disclosure of the Rhein-Main-Donau-Kanal, and thereby the Wiener Hafen gains importance. In 1996, the harbour handling amounted to 1.7 million tons.
The Wiener Hafen consists of 3 harbour facilities: a key element is the Freudenauer Hafen with the biggest container terminal in a European inland harbour (1996: overall container handling 159,049 TEU), and with storage centre, duty free area, car terminal and the head of 3 of Vienna's harbour associations, it still lives up to its original function as protective and winter harbour. The Alberner Hafen, originally conceived as grain harbour (granary capacity: 90,000t), still plays a major role in corn exports today. The oil harbour Lobau is also a protective and winter harbour for oil tankers and is connected through pipelines (amongst others Barbara-Brücken) with the central fuel depot and the OMV refinery Schwechat. The Hafen Freudenau is completed already; another extension of the water-land-transhipment options is planned for the Hafen Albern. In 1962, the Wiener Hafen-Betriebs Ges.m.b.H. (today Wiener Hafen Ges.m.b.H.) and in 1979 the Wiencont Containerterminal Ges.m.b.H. were established. Air transportation (aviation, Austrian Airlines) has its centre at the Vienna International Airport Wien-Schwechat.
Vienna International Airport is located to the southeast of Vienna. The airport handled over 237,400 arrivals and departures in 2006 and was frequented by 16.86 million passengers. Following lengthy negotiations with surrounding communities, the airport will be expanded to increase its capacity by adding a third runway. The airport is currently undergoing a major expansion(construction of several new buildings) to prepare for an expected increase in passengers.
