Hi!

In this changeset, Rookes Way was set to access=permit - this is used where a permit is easy to apply for and is usually granted, but your comment was "No public access" suggesting that such a permit would be hard to obtain.  Secondly, this section of road already has vehicle=no set, which would override the access=permit for vehicles (bicycles, cars, taxis, etc., but not buses due to the bus=yes tag), so this only leaves pedestrians as needing a permit to walk along here.  I've set it back to bus=yes, emergency=yes, and vehicle=no - bus and emergency override the vehicle tag as they're more specific.
