In my opinion, "we" should have started with indisputable, objective, physical attributes/descriptions first: width/lanes, separated/two-way, grade-separated/no; on/off-ramps or intersections, etc. Then you add in government classifications, if they exist, which include membership in national/regional/local networks/routes, etc. After that, you add in a "hint" that codifies local opinion/convention about the usage of the road. The penultimate step, if we have the resources, is to have the DB server execute some heuristic algorithm that does a localized network analysis to "weight" the segments based on the weight of the connecting roads. Then renderer/stylesheet authors can make a choice between algorithmic/objective or subjective classification. _______________________________________________ Talk-us mailing list Talk-us@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-us
