sorry, I was not precise, what I meant to say was that residential roads are not intended for through traffic. According to the context (e.g. oneway and dead end, or a grid) you may be able to “bypass the main traffic” and be faster (when the principal road is congested), but you are not supposed to do it, and it will usually be slower (slower speeds, pedestrians, no right of way at crossings, penalized at traffic lights etc.). Or in another context it will not be possible to go “through” a residential area, you can only enter and leave “at the same side”.

You may sometimes/often be able to go through the residential area on residential streets, but it doesn’t make them roads for through traffic. The roads for through traffic are usually tagged with tertiary+, minor ones with unclassified, so they can’t be residential ;-)

Maybe I don’t understand the word “access” correctly here, but if I think about an access road to a residential area, it would be different from the residential roads in the area. I would suggest to clarify this in the wiki (remove access or illustrate what it means).

Anyway, this is the result of an edit from February this year, where the long-standing definition was changed by removing this:
but which are not a classified or unclassified highways.

this should be reverted, and I would be glad if someone did it now, because I cannot do it myself at the moment. Thank you.


Cheers Martin
