[OSM-talk] highway=tertiary[_link?] (was: Re: highway=secondary_link)

[Steve Chilton]

One particular use of the foo_link info is that all down to secondary have a seperate position in the mapnik rendering order (painter model) - BEFORE all non_link instances. This means that the ugly "junctions" between say a motorway_link and a less importantly ranked road are now avoided, and they merge properly. It used to overprint the motorway_link over the lesser one and look wrong. So, I would encourage using the foo_link tags when merging road types.
 
Cheers

	I'm not sure I can think of any examples in the areas I'm familiar with.
	Perhaps that's just due to local road design though: link-like
	structures seem to be reserved for faster, more multi-lane road designs.
	
	Not having link roads: a concrete criterion for highway=tertiary? :-)
