Physical separation doesn't necessarily mean that it's impossible to cross, it might be no more than a 20cm high curb that an emergency vehicle or a SUV easily could cross. I still think it's more straight forward to map as two separate ways than to add tags to provide a logically consistent view about how to drive from A to B in a legal way. Bank robbers and emergency vehicle drivers make anyway their own decision on the spot. And about pedestrians, I add sidewalks around such street and tag the street with foot=no. /Markus _______________________________________________ Tagging mailing list [email protected] http://lists.openstreetmap.org/listinfo/tagging
