- It is a small city
- It has a good mixture of urban, rural and long-distance routes
- It has a good mixture of frequencies, from 6/hour primary services to 1/2hours to outlying areas
- The network is mostly radial, with routes that converge
- User:Chriscf lives there
Points 1 and 2 mean that any result should be scalable. Points 3 and 4 make it a suitable testbed for routing. Point 5 is a matter of convenience for the person that started it. :-)
4 Morriston Hospital; 4A Parc Gwernfadog
A major radial, complicated by the evening/Sunday 4 operating to the Hospital through Gwernfadog. From 4, Heol y Deri and Llanllienwen Close are missing; all ways for 4A present.
Operate either direction of a circle through Townhill. At first glance, appears to be complete, but will need to verify.
Some services continue to Gorseinon. Services 400 and 404 operate the same route, with slightly different paths through Waunarlwydd, and some back streets for both 17 and 400/404 are missing there. I'm unsure of the loop the 17 takes in Gowerton these days, but I'm sure there's something missing.
All ways as far as Caereithin, very little in Blaen-y-Maes and Portmead themselves.
Much of this would appear to be missing.
36 Morriston Cross
All ways present and tagged.
A good selection of routes to Mumbles, along Gower, and through the Uplands would be useful. On the East Side, there is only 6 (Port Tennant) and 44 (Grenfell Park).
