I didn't know you can u-turn on most trunk roads legally so why aren't we showing those as 2 seperate ways? > My justification was in the fifty million messages that came before this. Lots of people believe in a god of one sort or another, does it make it so just because billions of people say there really is a god? If there is a god because billions of people say so, which one or ones exist and which don't? Just because someone expresses an opinion doesn't mean it is true or the best way to do something, merely an opinion someone has stated and others agree with. > I believe we should define our terms based on the purpose we are trying to > accomplish.

A way is a physical feature, lanes are features of ways, if all the ways a physically connected to each other than it's a single way otherwise residential streets are all tagged wrong and we need to redo them as a way in each direction. > If you want to treat a residential street with a clearly marked center line > and no allowance for U-turns as 2 parallel ways, be my guest.

In some places you aren't allowed to u-turn except where signed as a valid u-turn place. A way is a physical feature physically seperated from other ways, anything joined is a single way but may have 1 or more lanes, if we could tag lanes this would be a moot argument and this is what we should be doing, then people wouldn't be trying to join ways with relations to describe a physical bridge which is a single physical object. _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
