true, but we need to consider that osm data is not perfect and we don't have good editors to draw parallel ways. also it may be a long way to go until osm is perfect. In this example it seems just too easy for a good router to do the right thing without hard facts. This can be done by the router or some intelligent preprocessing if compute time is critical as an example mkgmap does these type of preprocessing to reduce the number of unnecessary announcements and creates the routing graph accordingly. We might reach the state where all rouads are mapped with lanes, yellow lines, all turn restrictions … but in the meantime it shouldn't stop us from using fuzzy data in an intelligent routing algorithm. Ans whenever I has tested Cloudmade routing it was not so great. _______________________________________________ Routing mailing list [email protected] http://lists.openstreetmap.org/listinfo/routing
