The blue signs are on quite a few surrounding roads, so it's not just a local, but the yellow looks official, and as there's a single yellow line down that side of the road, I believe it, but as far as I'm concerned, the other side should be fair game tbh.
The blue signs are official as well.
Car usage and parking
The Local Authority has banned parking on all roads immediately adjacent to the University campus unless you are a resident in one of those houses. You may be liable to disciplinary action if you ignore these restrictions.
Parking and Cycling
The University operates a compulsory registration scheme for student cars. Student vehicle registration data is used by the University for the investigation of student discipline offences, and specifically to ensure that students do not park contrary to University regulations in the residential areas signed 'No University Parking', which surround the campus.
