Access class specific turn restrictions
Hi, today I got this warning: 2013/03/15 13:13:11 WARNING (RestrictionRelation): 63240002.osm.pbf: Turn restriction http://www.openstreetmap.org/browse/relation/2818347 (at http://www.openstreetmap.org/?mlat=60.17315&mlon=24.92289&zoom=17) lacks 'restriction' tag (e.g. no_left_turn) The wiki http://wiki.openstreetmap.org/wiki/Relation:restriction says that restriction:bus=no_right_turn is valid markup. It also lists things like restriction:motorcar and restriction:bicycle. Currently, mkgmap only supports the 'except' tag for restrictions. So, I guess that the above might be written as restriction=no_right_turn except=motorcar;bicycle I think that it is cleaner to use restriction:* for explicitly defining the restricted vehicle classes, unless it is restricted for all. (Sometimes buses can go straight while others must turn, on a lane that is primarily reserved for public transport. This one is a sharp turn to a narrow road, probably too sharp for wider vehicles. Or they want to restrict tourist bus traffic in the area.) Best regards, Marko

I'm using mkgmap version 2540 and turn-restrictions are applied in general if --ignore-turn-restrictions is not used. So far, so good. But does mkgmap really support the except tag? For me, the example of a turn-restriction is working as expected for motorcar routing. But using bicycle routing, the restriction is applied the same way. So, regardless of the except tag, routing follows always the turn-restriction. Routing with the bicycle straight across the crossing is only possible if --ignore-turn-restrictions is applied. In addition, is it possible to 'manipulate' the tags of a turn-restriction before mkgmap is processing them? I tried - just for fun - the following in the style's 'relations' file, but without success / any noticable change. Thank you. -- View this message in context: http://gis.19327.n5.nabble.com/Access-class-specific-turn-restrictions-tp575... Sent from the Mkgmap Development mailing list archive at Nabble.com.
Hi, mkgmap evaluates e.g. except=bicycle or except=psv, but not (yet) a comma separated list of the value. If I got this right, the tags are evaluated before the style is applied. Gerd littlehelper wrote
