OTIND, Vienna, December 2016 / Travel

Flying to Vienna

Vienna can comfortably be reached by plane from many destinations. The Vienna International Airport is served by most regular airlines and also by several low-cost carriers. See the website of the Vienna International Airport for detailed information.




Using a long-distance train

Especially if you come from not so far, it may pay to check train connections (there are frequent and fast connections from Zurich, Frankfurt, Prague, Budapest and other destinations). For detils see the website of the Austrian Federal Railways (OEBB).




How to get to town from the airport

The airport is connected to the city in several ways. We recommend the following:
  • Train service to Vienna Main Railway Station (Wien Hauptbahnhof) with long-distance trains (RJ, IC). Trains are running each 30 minutes from 6'30 till 23'00. For a detailed schedule see the website of the Austrian Federal Railways (OEBB): here.
    -- Costs: Approximately 4 Euro (per person/one way).
    -- Tickets can be bought onboard from the conductor who passes by (sometimes no conductor appears...never mind ☺) or through the website of OEBB.
    -- At the Main Railway Station you can change to the public transport service (underground, tram, etc.). Train tickets do not include a possible following journey with underground/tram/etc.

  • Order a taxi (Airport Drivers) in advance from this site. Especially if you travel in a small group or have more luggage this is a good option.
    -- Costs: Up to 4 passengers, 33 Euro (total/one way). Up to 8 passengers : 48 Euro (total/one way).
    -- The driver will meet you at the airport right after the exit of the luggage hall.
Other possibilities are:
  • Train service to a local railway station (Wien Mitte) with the regional train S7. Trains are running each 30 minutes. For a detailed schedule see again the website of OEBB.
    -- Costs: Approximately 4 Euro (per person/one way).
    -- Tickets must be bought in advance and stamped at the platform or bought through the website of OEBB.
    -- At the railway station you can change to the public transport service (underground, tram, etc.). This following journey with underground/tram/etc is included in the ticket.

  • Bus service to several destinations in Vienna with Vienna Airport Bus (Flughafenbus). Buses depart from platforms at the exit of the arrival hall. For a detailed schedule see here.
    -- Costs: 8 Euro (per person) for a one way journey, 13 Euro for a return trip.
    -- Tickets can be bought from the driver. This ticket does not include a possible following journey with underground/tram/etc.

  • Train service to the local railway station (Wien Mitte) with the City Airport Train (CAT). Trains are running each 30 minutes. For a detailed schedule see here.
    -- Costs: 11 Euro (per person) for a one way journey, 17 Euro for a return trip.
    -- Tickets can be bought online or from machines right before or at the platform.
    -- At the railway station you can change to the public transport service (underground, tram, etc.). A possible following journey with underground/tram/etc is not included in the ticket.

  • Get a taxi in front of the airport building. This is usually expensive, and it may happen that there is no taxi available.

OTIND, Vienna, December 2016 / Accomodation

Accomodation

There is a wide range of hotels of all categories and price ranges. You can use any common booking engine like booking.com or budgetplaces.com to look for a place to stay.

We only list a couple of decent, resonably priced, and well located hotels.
  • Hotel Terminus, Fillgradergasse 4, 1060 Wien (website).
  • Hotel Admiral, Karl Schweighofer-Gasse 7, 1070 Wien (website).
  • Hotel Drei Kronen, Schleifmühlgasse 25, 1040 Vienna (website).
  • Motel One, Elisabethstrasse 5, 1010 Vienna (website).
When you plan your trip, please take into account that the time before X-mas is a popular and quite busy tourist period. Hence hotels tend to be fully booked quite some time in advance.
OTIND, Vienna, December 2016 / Public Transport

Public Transport in Vienna

The public transport system in Vienna is well-developed. To give you an overview, it includes regional trains (S-Bahn, numbered "S1", "S2", etc.), underground lines (numbered "U1", "U2", etc.), trams (numbered "1", "2", etc., a few exceptional numberings like "D"), and buses (numbered "1A", "13A", etc.).

Scaleable map of major lines.

Tickets can be bought from machines at every train/underground station or ordered online in advance. There are tickets for various possible time ranges, for example:
  • a single journey (the notion one journey includes changes of lines),
  • 24h, 48h, 72h,
  • 8 days (not necessarily consequtive),
  • weekly (monday-sunday).
All tickets should be stamped at the beginning of their validity period. Depending on the type of ticket, this period can be one single journey, one day, one week, etc. Machines (little boxes) to stamp tickets are located
  • for S-Bahn/underground generally in the hall before getting to the platforms, latest at the platform,
  • inside trams and buses.
In principle tickets can also be bought from machines inside trams and buses. However, unless necessary, this is not recommended (sometimes these machines don't work, sometimes one doen't have coins, etc.). Detailed information can be found at the website of the Wiener Linien, see here (english version available). This site includes a practical interactive journey planner (click the Journey button on the site).

Location Map

Here is a map of the surrounding of the TU Vienna. In this map the Freihaus building is marked by a violet disk, and the restaurants listed as Close to the TU Vienna are marked by red stars.
Surrounding of TU

Here are maps of Vienna and the inner city. On the latter you find some coffee houses and the location of the conference dinner.
Vienna Inner city

Conference Dinner

The Conference Dinner takes place Sunday 18.12.2016, 19'00 in the Zwölf-Apostelkeller. This restaurant is located in the very heart of the city (Sonnenfelsgasse 3). They offer a buffet with traditional Austrian dishes including some vegetarian dishes.

We shall gather after the last talk in front of the lecture halls and depart at 18'15 to walk there together (about 20 minutes walk through the inner city). Of course you can also walk there on your own.

The buffet, non-alcoholic drinks, and beer/wine up to a reasonable amount is covered.

Walk through the old town

We informally organise a walk through the old town on Friday 16.12 evening (guided by our chief-tourist Jussi Behrndt). We meet Friday 19'00 in the Freihaus building, red area, ground floor.

OTIND, Vienna, December 2016 / TU Wien

The Vienna University of Technology

  1. Map of all TU Vienna buildings.
    The conference takes place in the Freihaus building, shown on the map as the part of D including the number 4 (which, by the way, marks the canteen).

    The address is Wiedner Hauptstrasse 8-10, Vienna. See also the Location Map offered in the drop down menu 'The Venue' on this website.

  2. The Freihaus building itself is structured into three vertical units: The red, yellow, and green areas.
    These areas are connected; you can pass from one to another on every floor. Upon entering you find yourself in the red area.

    There are elevators and main staircases in each area. The main staircases lead from the ground floor up to the 2nd floor (ground floor = floor 0). There are several small but somewhat hidden staircases leading further up.

  3. The registration desk, coffee breaks, and common rooms are located on 3rd floor / green area (Sem.R. DA grün 03 A, Sem.R. DA grün 03 C).
    Click here to get a layout of this level.
    You can get to the 3rd floor by using any elevator.

    Lectures take place in HS 7 and HS 8 (Lecture Halls 7 and 8) which are located on 2nd floor / yellow area. Lecture halls are equipped with blackboards, overhead projector, and beamer+computer.
    Click here to get a layout of this level.
    You can get to the 2nd floor from the entrance by using any elevator or main staircase.

    To switch between 2nd and 3rd floor use any elevator or one of the small staircases.
