I believe this has happened to me in the past while driving; a user was taken off the highway via the exit ramp (in this case it runs parallel with the highway for quite some time) – then immediately routed back onto the highway.
Is this commonplace, or could it be the result of some old traffic data? Cheers.
That happens a lot in Texas, too.
I’m wondering if I should toss it up to old data, or data the user wasn’t privy to in terms of traffic routing and mark “Solved”, or mark “Not Identified”.
There are things that can be done to prevent routing through the collector lane of ramps. It’s discussed in the wiki Limited access interchanges style guide.
Another method that has been implemented in the routing server is to have the segments immedately before and after the collector lane be identically named. The routing server is not supposed to route from a road to a ramp and then back onto the same road. So the highway segment before the ramp split and the highway segment after the ramp merge should have identical city/street names to prevent that type of ramp routing.
Make one (or both) of those changes and mark the UR solved.
Ok, Mike. Solve this one:
That’s cheating! :lol:
It’s not ramp to ramp routing, that’s using the frontage road. As I understand it, there’s no way to allow “proper” routing and prevent ramp -> frontage ->ramp route. If you’ve figured one out, I’d love to hear it.
BTW, aren’t there some turn restrictions missing on those ramp segments?
Believe it or not…no. You can pull a “U-turn” (so to speak) and go down the frontage road the way you just came from. Sometimes there’s a small little ramp, and sometimes there isn’t. If I remember to take a photo of the one I run across on my route on Monday, I will.
I had to clear out 7 URs from that intersection before posting that.
This is some tricky stuff. ;-0

And a perfect way to keep somebody with OCD occupied for huge swaths of time. :lol:
This happened to me 5 times on I-85 from Atlanta to Raleigh yesterday. One time it wanted to take me onto Business I-85 (stop lights and all) only to meet back with I-85 again.
