You can also come by bus. Of course you can drive to the conference too. The M8 exits for the University are junction 19 if travelling east and junction 18 if travelling west. The A82 Great Western Road runs just to the north of the University, the A814 Clydeside Expressway runs just south and Byres Road just west. There are many options for travel within the city.
Taxis are pretty cheap.
You will see a lot of black taxi cabs around. The stop nearest the University is Hillhead. The Tower is a good landmark to use when navigating. You can see it from most of the city. The main conference will take place in the building right next to it.
