One would think that a router would be able to prefer a parallel footway without a special tag. One real problem with routing along sidewalks is that they sometimes don't have curb cuts at intersections, yet it's legal to cross there. Example: http://maps.google.com/maps?ll=28.457321,-81.45624&spn=0.000993,0.002575&t=k&z=20&layer=c&cbll=28.457407,-81.45623&panoid=W8rLGRkFUgFWzRRpWLSWCg&cbp=12,59.26,,0,10.44 To route correctly here, you'd either have to draw an incorrect footway, or the router would need to be able to "jump" a gap if there's no barrier (and you don't tell it you're in a wheelchair). _______________________________________________ Tagging mailing list [email protected] http://lists.openstreetmap.org/listinfo/tagging
