And these situations are more common than you may think. Built-up
areas
are the most common where such a thing happens here as they're of
course the largest kind of zonal restrictions, and each city will have
it's roads crossing them without being part of it. But I've also seen
it with zones with parking restrictions or zones with speed
restrictions.
And you just can't tag the road with for example an overruling
maxspeed
tag, as the road may just have its default maxspeed in which case you
don't tag that speed.
Yeah but the default maxspeed becomes the one of the zone. So the road
would then need a specific restriction, or the zone would need to be
split. The following evaluation hierarchy could be used:
1. Use the default restrictions for that type of road.
2. Is a road in a restriction zone? Use those restrictions instead of
in 1.
3. Does the road have a specific restriction on it? USe that instead
of 1. and/or 2.
