This is very motorway / motorcar specific. Many roads in Africa and on hiking trails are not signposted and can only be described by free form strings. I propose that we either tag the destination way e.g. the motorway_link, or use 1 relation for each possible maneuver (from='source' to='dest'). It's up to the routing program to look ahead for signpost messages. We need 2 sets of instructions : * Freeform instructions that will typically be produced by a website or non-gps device. For example the motorway_link that goes to Wuppertal can be tagged with "At the Acme junction, take the middle lane for the exit marked 'Wuppertal'". For messages fitting a certain layout, we can have machine translation into other languages e.g. using 'sed'. * A message from a predetermined set that can easily be turned into audible instructions on a resource poor GPS. The tag must also encode the distance before the intersection that the instructions must be played. It can even be a set of instructions e.g. "200m StayInMiddleLane; 100m StayInLeftLane; 50 JoinMotorway" _______________________________________________ Routing mailing list [email protected] http://lists.openstreetmap.org/cgi-bin/mailman/listinfo/routing
