This off-and-on isn't difficult at all

Post by
Hey, all.

Any thoughts on how to prevent the off-and-on you'll see in this livemap link? There's no crossover or tie I can think of that will reasonably do it.

To be honest, I'm not even certain it should be disallowed. There's often a big backup on I-5 N around this curve, and although convoluted, it does get around it, often, and since it's hitting at least one city street, it's technically not 'just' an off-and-on.

There's a few overlapping ramp segments here (to the west) which seem to be the antithesis of simplified mapping. Why can't they be combined instead of being stacked? Does it have to do with which lane you are coming in on?

Livemap with the navigation addon is usually enough because you can quickly narrow down to the instruction you are looking for, but it can't take into account time-of-day adjustments yet, nor, as you stated, can it give 3 routes. But the nav add-on makes it very clear the type and "written name" of each navigation instruction which is sent to the app. Can't test abbreviations though.

The call to the routing server does accept an argument for "time offset from now" which makes it calculate a route for a time in the future, which can then take into account historical traffic conditions, but there's currently no way to do that in the livemap.

The "set as start point" has been in the app since version 3.1 or something close. It was in 2.4, removed in 3.0 and then brought back pretty quickly due to community demand.

I'm curious about the advantages of this configuration? Why the parking lot segment rather than the turn restriction?

If you use a ramp and a turn restriction. Couldn't you then simplify the whole thing by eliminating the four segments and bringing all four junction nodes together as one? I'm not seeing the point of the four segments except to make the one a parking lot segment. And I don't really understand the advantage of the parking lot segment.

I see, it does make sense as a mechanism to avoid MPs. And any undue attention to the complexity could certainly be a problem.
However, the following surprises me:
skbun wrote:* The only nav advice Waze will ever give a person coming from I-5 N is to take the left ramp of the two, and in the context of this exit, it's 'straight ahead'. . . . The placement of the bowtie is right in front of the actual road split so the TTS shows the right distance.
I'm surprised drivers coming from I-5 N get any instruction at all there. I would have thought that continuing on the ramp type segments would make that route the best continuation and you wouldn't get an instruction.

If it's a real problem, you could work here:

https://www.waze.com/editor/?lon=-122.4 ... s=54304608

And make sure that this ONLY connects where it's supposed to, and of course make sure other roads work as well. I did this in Louisville on one section that persistently had users going off onto a side ramp and then back onto the interstate. I made it so the ramps ONLY went where they were supposed to, and not back to the interstate, with a bit of extra connection ramps and a parallel path or so.

Here's how I did it there, maybe a similar approach will work for you. Be careful, and trace the paths to make sure you get it right! :)

What in the world is this segment? :) Might recheck this right here, something odd going on.

Not sure this is really connected?

I didn't trace it out yet, just looking at the basics of what you did. :)

Alan,

From my suggestion, the attempt was to prevent Waze from routing users to the slip road then back onto the interstate. I had a case of this in Louisivlle, KY that I kept getting UR's on and I made some adjustments. I had to make some parallel stuff but not as extensively as the one he made.

He hasn't responded yet, so I think I'm going to take a shot at some of the stuff I saw and go over it, as I think it's a bit broken right now, I just had no time to look into it more yesterday.

I've edited, I think it's right, but there's no (sane) way to completely isolate everything here. I really hate these sliproad configurations, they're difficult to fix with additional roads and connectors... Is there ever a valid case of Freeway I5 to ramp to ramp2 to rampN to Freeway I5 is valid? Two different freeways, yes.

I missed that one entirely. I'd think he meant to use Ramp there but I'd have to trace it out.

Haven't heard back from the OP, I wonder if he's still working on this.

skbun,

Sorry I made edits post your completion, but there was at least one segment that wasn't connected that needed to be, and a parking lot segment that wasn't connected either, was "under" several others.

So if you meant the parking lot "trick" to be on the north side too, you'll want to modify there and add it.

Complicated trickery, but hopefully is all connected properly. :) I might try one of those navigation emulation things and see what happens, since live routing never seems to give the same route to the client as on the website.

Cheers.
