Hi, yes - the roads have previously had no name and we have not been able to find evidence of existing names to use. Bailrigg House Lane was originally connected to the road that is now called Bigforth Drive via the path that runs down the hill towards Bigforth Barn, but we haven't found evidence of a name in use at that time.  
I have asked about signage, nothing confirmed as yet but I would imagine this would be installed at some point.
The University's interest in OSM is with Mazemap which is the University's chosen wayfinding platform. Mazemap uses OSM as a base layer, on to which it layers floorplans and other points of interest. So if we spot an error or missing information on that base layer then we'll update OSM.
