ANSWER:

If the university is within your city limits then no problem in this as long as it’s safe to commute.

The prohibition is for a woman to travel out of the city borders without her male mahram. It is prohibited to be in the bus alone with the driver without any passengers. 

I go to my university through bus. I go to the bus station without any mahram. Is it sinful? And as in the university bus I alone go without mahram. Is it sinful too?? What if I don’t have any mahram to take me there, in this case would it be sinful too??
