There are no guidelines for labelling roads where a street name exists but it forms part of a named route. The question was raised in an unlock request with regard to the naming of streets which form part of the South Circular Road http://www.waze.com/forum/viewtopic.php?f=265&t=24014
The route going through my editing area was already labelled just as A205 - South Circular Rd, and there was no listing of the street names of those roads - Atkins Rd, Streatham Pl, Christchurch Rd, Thurlow Pk Rd, Dulwich Common. I relabelled the roads in the form A205 - Atkins Rd (South Circular Rd) on the basis that either would be found in a search. However, I've been told this is wrong, although not why.
How should we label such roads? Currently, Atkins Rd which runs west from Streatham Pl, only forms part of the South Circular for a short length. The road then continues as an ordinary residential street. Clearly, it's correct to label the street sections as Atkins Rd. The section that forms part of the South Circular is also Atkins Rd and should be labelled accordingly.
What's the best way of labelling in this example?
