Same as MisterSpock, I don't know about in general, but I can talk about my experience.
I currently live on campus in a dormitory, and I have two roommates. My roommates do know that I have Aspergers, and a little of what it means for me and how it effects me, but it would be up to you whether you tell your roommates or not. They are respectful girls, and we get along well, so it is not a big problem for us, but your situation might be different. Each college dormitory is different. Ours is not too bad, but can get loud at times.
Our campus is in the middle of a city, so it can be busy outside. There is always something going on if you want something to do, but it is also really easy to find a quiet spot to read, destress, or just be alone.
The hardest part about starting college for me was figuring it all out. There are many more people than at my high school, you have to go outside more, classes are run differently, and there is much less structure, which was difficult for me to adjust to. After adjust, college can be really fun and great, and will be good!
Good luck transferring to your new school!
