Hi
I work at the University and have lived in Brighton for 30 years. I would say the best way to travel around Brighton would be by bus. The City isn't that big and there are so many buses that run regularly that can get you around.
The university operates a term-time shuttle bus, the UB1, between the Brighton campuses and Varley Park Halls of residence, free to all students and staff. So this may be helpful to you if you are studying on one of our Brighton campuses.
Otherwise Brighton & Hove Buses operate in the city and offer student bus fares.
Personally I walk a lot too as there's always interesting things to see around Brighton on foot and it usually doesn't take to long to get places. The University encourages students to walk or cycle as it's a great way to keep fit, manage your wellbeing and is very low cost.

I hope this is helpful. I hope you enjoy your time at Brighton Uni!
