For example, shading just one side of a road. However, if the road is tagged as highway=residential you'll still get the shading on both sides of the road.
<br><br>One way of preventing that is to switch off the abutters rendering rule for highway=residential, but then you loose the abutters everywhere else on the map. So unless you fix the whole town you don't any real benefit from using the landuse tag.
<br><br>Does the following proposal satisfy all the requirements:<br>1) Preserve the current rendering behaviour of <span style="font-weight: bold;">highway=residential</span> (but mark it as deprecated)<br>2) Use <span style="font-weight: bold;">
highway=unclassified, residential=yes</span> to mark up roads with houses along them<br>3) Use <span style="font-weight: bold;">landuse=residential</span> to demarcate the residential areas<br>4) Do not overlap areas that use the landuse tag unless they really do overlap and are tagged as different layers.

<br>and while they possibly are unclassified roads, they want to be rendered<br>differently from either residential (grey stripe) or unclassified (no<br>stripe). This is why I proposed highway=urban, for a typical urban street
<br>like a high street with a mixture of premises.<br><br>But even this doesn't really work all that well, as you can have<br>highway=primary High Streets, which need the abutters-like stripes<br>alongside. Maybe an 'abutters' tag on the way might be the way to do it,
<br>which overrides the kind of road when rendering. We can still abolish<br>abutters on the segments (and get rid of segments too), but have the<br>convenience of a simple rendering.<br><br>There's also some residential roads which are more important than others.
<br>But someone has a proposal in for a tag which provides a hierarchy like<br>this, which I think does the job there.<br><br>But at the moment it sounds like there's no consistency, so there's going to<br>be problems rendering stuff in the future.
