Travel information

Getting to the conference

The conference venue lies 2 minutes on foot from the underground stop Karlsplatz; lines U1, U2 and U4 stop there. On Karlsplatz orient yourself towards this building, the actual conference takes place in the building behind it, called “Freihaus” building. The entrance is approximately at coordinates 48.199N, 16.3677E.

The Freihaus has three sections, coloured red, yellow and green. The conference will take place almost exclusively in the green part, which is reachable by going to the left after entering. You will be commuting between the 2nd, 5th (breaks, conference office), 7th and 8th floor in the green section, which is possible using lifts (or well-hidden staircases).

Visa information

Austria is part of the Schengen area. Nationals of the EU member states, the European Economic Area and Switzerland do not require visa. There are certain other nationals that can enter without visa based on certain bi- or multilateral agreements (more details, click on “General information”).

By aeroplane

Vienna is connected to many cities worldwide by Vienna International Airport (IATA code VIE). The airport is located outside the city borders, but directly connected to the railway system. We recommend against using the City Airport Train (CAT), which is green and expensive. Regular trains commute between the city centre and the airport at a much cheaper rate (4.20 EUR per trip) and are only slower by 4 minutes. The relevant lines include S1, S2, S7, and regional trains R xyzuv; directions from the airport: Wolkersdorf, Gänserndorf, Floridsdorf, Laa/Thaya; all of them go through “Wien Mitte Landstraße”, which is connected to underground lines U3 and U4. You can plan your journey here by entering “Flughafen Wien Bahnhof, Flughafen Wien” into the “From:”-field.

By train

There are two stations that you are likely to arrive to: “Wien Hauptbahnhof” (Vienna main station) or “Wien Westbahnhof” (Vienna Western station). Both are connected to the underground: Hauptbahnhof is connected to U1 (direction “Leopoldau” to get to the centre); Westbahnhof is connected to U3 (direction “Simmering” to get to the centre) or to U6 (both directions bypass the city centre).

By bus

International bus lines stop at the Vienna International Bus Station (VIB). Across the street there is the stop “Erdberg” of underground line U3; take the direction towards “Ottakring” to reach the city centre.

By car

To everyone, who wishes to travel by car, we give the following warning: Vienna is a very car-unfriendly city. Note that Vienna is subdivided into several parking zones that severely restrict the possibilities to park cars (at least from Monday to Friday from 9:00 to 22:00). TU Wien is located in the 4th district of Vienna, whose parking regulation is as follows: from Monday to Friday between 9:00 and 22:00 it is possible to park cars only against payment for a maximal duration of 2 hours. Between 22:00 and 9:00 parking is free, but spots are usually scarce. On Saturday and Sunday, parking is usually free, but be aware that in some places additional (stronger) restrictions apply, possibly also on Saturdays. The details for the 4th district can be found here, if you are staying in a different district, general information is available here (in German). Under these links you'll find interactive maps that upon clicking display the concrete parking conditions.

Parking tickets need to be bought in advance (details in English can be found here), usually in tobacco shops, some tobacco vending machines also sell parking tickets.

TU Wien offers on-site parking in an underground three-storey car park (Operngasse 13, 1040 Wien). The rates are 4 EUR per hour, 40 EUR daily maximum. If you are using this option, it is perhaps desirable to park the car in level -3, as the green part of the building is accessible by lift only from this floor.

Getting around in Vienna

Using public transportation is very convenient in Vienna. Plan your journeys here or here. Using the underground offers a particularly fast possibility to reach your destination. A map of the underground network can be found here.

If you are planning to do some additional sight-seeing in Vienna, there are daily tickets (valid until 1 a.m. of the next day, 5.80 EUR), 24 hour (8 EUR) 48 hour (14.10 EUR) and 72 hour (17.10 EUR) tickets available (more information).
