Hi Maning,
2010/03/18 20:31:26 WARNING (StyledConverter): philippines.osm: Motorway exit null (http://www.openstreetmap.org/?mlat=7.07588&mlon=125.62656&zoom=17) has no motorway! (either make the exit share a node with the motorway or specify the motorway ref with a exit:road_ref tag)
There is no motorway nearby, and this is a barrier=gate, nothing to do with motorways. I have seen this when a motorway_link forks in two branches, or something like that. I fixed it by setting an exit:road_ref tag on the junction. Do you see this when using the defaut style? Are you translating barrier=gate to a symbol that is reserved for motorway exits?
2010/03/18 20:31:26 WARNING (StyledConverter): philippines.osm: Motorway exit closed subdivision gate (http://www.openstreetmap.org/?mlat=14.13477&mlon=120.97857&zoom=17) has no motorway! (either make the exit share a node with the motorway or specify the motorway ref with a exit:road_ref tag)
Same here: this is barrier=gate.
In my style I assigned barrier=gate as a highway exit: barrier=gate [0x2001 resolution 24]
Why did you do that? For what it is worth, the default style assigns highway=motorway_junction to 0x2000 and some barrier=* to 0x660f. I am also assigning traffic_calming=* to 0x6614, and it works fine. Best regards, Marko
