The term "importance" isn't defined, but it must have a general meaning of "size / connectivity / capacity". I would have thought that typical road speed was a useful (though indirect) way of interpreting the importance of the highway for the road grid, in the lack of any other information. Another consideration may, or may not (depending on your philosophy) be routing. Routing software will take the tag you use to decide on routing decisions, and typically it will do that by using the tag you chose to allocate an average speed to the road segment. -- Charlie _______________________________________________ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging
