Within the city of Zurich, you can easily travel by tram or bus. For longer distances, you can also travel by train. For detailed traveling schedules you can check connections and ticket prices on both the timetable of the Swiss Federal Railways (SBB) (train) and the website of Zurich Public Transport (VBZ). Within the Canton of Zurich, both pages will provide the same connection results.
Taxis are also available, but they are very expensive and in most cases, riding by public transport is also faster.
Within the City of Zurich
You can find a pdf of a city plan including tram, bus and train lines here: City of Zurich Network.
Tickets: Within the city limits of Zurich, you need a "1-2 zones" ticket for zone 10 ("Stadtnetz"). Single ride tickets are valid for rides within one hour. A return ticket is in fact a 24h pass: it is valid for 24 hours for unlimited rides. Tickets are valid for all trams, buses, trains (2nd class cars only) and boats (2nd class deck only) within the purchased zone(s). All campuses of the University of Zurich lie in zone 10. However, note that the airport is not in zone 10. For rides from the airport to the city or back, you need a ticket for three zones: 10 (counts double) and 21. If you already have a valid ticket for zone 10, buy a zone upgrade ticket for 1-2 zones (that's cheaper). Please check whether date and time of issue is printed on your ticket (this should always be the case when buying a single ride or return ticket from a vending machine). If not, you need to stamp the ticket (at a ticket vending machine) before your first ride.
For a better orientation, you can have a look at the Google Map below. Or alternatively, use the following link to see the map with tram lines included: ICSE 2012 Google Map. We marked some of the important tram stations and conference locations. You can click on our big markers to get more information. (Please note that Google will not tell you the correct tram line numbers in the popup when you click on one of the very small tram symbols (instead of our markers). In the popup, click on the link "online.fahrplaninfo.zvv.ch" below the line numbers to get the correct line numbers.)
