That's not something that i would ever map as it would vary with any geometry change of the ways between the road the point you measure, added to the fact that it add nothing to explicitly map it (in my opinion at least). It is essentially what any routing app will calculate when you ask "find the nearest POI" for example.

It is, but surely in calculating that distance it is easier and better to simply map the paths?
