<html><head></head><body>It's true that most ramps in the U.S. don't have names, but I do know of a few that appear to. In particular, the I-4/I-75 junction in Tampa appears to have named ramps.<br>

There is a sign indicating that <br />this exit ramp leads to those places. <br /><a href="http://www.openstreetmap.org/user/mvexel/diary/22419">http://www.openstreetmap.org/user/mvexel/diary/22419</a> provides some more <br />information, and a picture of a complicated sign.<br /><br />If you wanted to, you could label ramps
with the destination <br />information. This would be done in your processing toolchain - and it <br />depends on what you want to feed the data into. If you were using <br />osm2pgsql, I'd suggest Lua transforms, but if you're using a different <br />ETL toolchain, there's probably a way to transform the data.<br /><br /><blockquote class="gmail_quote" style="margin: 0pt 0pt 1ex 0.8ex; border-left: 1px solid #729fcf; padding-left: 1ex;"> These ramps are extremely import: a large number of traffic accidents <br /> occur on them and we must dispatch to exactly the right ramp in a way <br /> that can be quickly identified from information provided by a caller <br /> (e.g. exit number is not helpful if the caller is already on the ramp).<br /></blockquote>Do have any data on how callers are describing their current location <br />when they are on a ramp? My guess is they would describe the destination <br />of the ramp or the exit number they took. Both of these are in OSM.<br /><br
/>I can think of some ramps which are long and in remote areas where if <br />you stop at the right place and look around, there are no signs to <br />indicate where you are. If you get a call from one of these locations <br />and the person doesn't know the area, there's probably no good way for <br />them to describe where they are.<br /><br /><hr /><br />Talk-us mailing list<br />Talk-us@openstreetmap.org<br /><a href="https://lists.openstreetmap.org/listinfo/talk-us">https://lists.openstreetmap.org/listinfo/talk-us</a><br /></pre></blockquote></div><br>
