Timisoara can be reached:

- by plane:    - directly to Timisoara (strongly recommended);

The English web page of the airport in Timisoara may be useful for information concerning flights and access to/from airport:

Timisoara Airport "Traian Vuia"

                     - to Budapest, where several low cost airlines fly from western Europe. The most efficient way to reach Timisoara from the Budapest airport is the shuttle service provided by the company Sirius. They require advance reservations, either by email at sirius[at]arad.ro, or by phone at +40 257 253 434. It takes 5-6 hours from Budapest airport to Timisoara, and they drop passengers at the desired hotel.

                     - to Bucharest, then taking a domestic flight or the train to Timisoara.

- by train:      Timisoara is about 7 hours distance from Bucharest, 6 hours from Budapest (Hungary) and 3 hours from Belgrade (Yugoslavia).

The English web page of the Romanian Railways is


To look for international train connections all over Europe, a good place is the site of the Austrian Railways. The English version of the page is


The required destination should be Timisoara Nord.

- by car:       If you travel from Western Europe take from Wien to Budapest the freeway M1; then after Budapest M5 to Szeged. Leaving the freeway at Szeged, continue towards Mako(Arad/Bucharest), and just before entering Mako there are signs directing towards Timisoara (you will cross the border at Csanad/Cenad and pass afterwards through Sannicolau Mare).

EU, US, and Canadian citizens do not need a visa to enter Romania. Otherwise the requirements depend on different bilateral agreements, so the safest thing is to contact early the Romanian Embassy in your country.

The Conference fee is 100 Euros, which is expected to be paid at arrival. A limited number of waivers might be granted to graduate students and young researchers; applications should be made in due time.
