Well, I was just testing MapQuest and it thinks that I-74's split there from I-77 is the main highway (somewhat). http://open.mapquest.com/?le=t&hk=7-OEgrKIB6&vs= It says "Stay STRAIGHT to go onto I-74 E." The problem is it's a "Left" exit. The line should say something like: "Take Left Exit #101 to continue on I-74 East towards Mt Airy/Winston-Salem." This is what Google says on their map: "Slight left at I-74 E (signs for Mt Airy/Winston - Salem)". Heck, I've been fighting with Google trying to get them to mention the Exit number for that step as well, but haven't had much luck. This is what we need to work with MapQuest to fix. Maybe a special "exit_left=yes" or "left_exit=yes" tag?

Here's such an example: http://www.openstreetmap.org/?lat=36.49591&lon=-80.74103&zoom=16&layers=M It's the I-77/I-74 split in NC. I-74 splits off to the left using an I-77 exit number (Exit #101). Something like this would need an extra tag on the node where the highways split. Looks mostly right as is, except I capitalize East (and want it in its own tag), hyphenate I-74 (because it is in a name field, not a ref), and would move the destinations to the towards tag: exit_to="I-74 East" towards="Mount Airy / Winston Salem" ref=101 OR exit_to_root="I-74" exit_to_dir="East" towards="Mount Airy / Winston Salem" ref=101 Because it is the start of the motorway, I see no reason to call it a motorway_link. I just continue the new motorway right up to the motorway_junction. -- Alan Mintz <[email protected]> _______________________________________________ Talk-us mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk-us
