New Orleans - I-10 and City Park Avenue Spaghetti Mess

[jasonh300]

I keep seeing URs about bad driving directions for people trying to get to Academy Dr. Today, I set up driving directions and followed them. They're very confusing due to the naming of the exits and slip roads around there. I've done some creative naming and angling of junctions around there that I think will alleviate the problems.

EDIT - Can't believe I forgot the permalink: https://www.waze.com/editor/?zoom=5&lat ... ts=9529383

This livemap shows the correct routing to get from I-10 Eastbound to Academy Dr.

These are the livemap script instructions, with the red ones being the ones you'll actually see and hear on the app.

depart from Pontchartrain Blvd
continue on I-10 E
keep right onto Exit 231A: Metairie Rd / City Park Ave
continue on Pontchartrain Blvd
turn left
turn left onto Exit 231A Metairie Rd / City Park Ave (several times)
continue on to I-10turn left
turn right onto Pontchartrain Blvd
continue on Academy Dr

These are the changes I made, which should generate the following instructions at the next update (TTS and visual on the app)

depart from Pontchartrain Blvd
continue on I-10 E
keep right onto Exit 231A: Metairie Rd / City Park Ave
keep right on Pontchartrain Blvd
turn left on Cross St
turn left onto Pontchartrain Blvd
turn left onto Cross St
turn right onto Pontchartrain Blvd

Any comments or suggestions?

That section of town is completely ridiculous. Nice work trying to tame it, I'll keep an eye on it.

"Cross St" is kind of a colloquialism. Perhaps "Unnamed road"?

Are there any other streets named Cross St? If so, would that impact search or routing?

I understand your intent, I just don't know what unintended consequences faux-naming a street might have.

[jasonh300]

There are a few Cross Streets in the area. No Unnamed Streets though. For now, that's what I'll go with, unless someone can come up with something better (I was halfway serious about "The Road Under the Bridge" but it's so long on the map...)

Now that I'm looking at it, that segment is actually signed as "to I-10 East".

I'm wondering what we should name those two segments of Pontchartrain Blvd that come right off Metairie Rd. They're prominently signed for I-10 and are used most often for access to I-10. We'd have to consider, however, that the lakebound segment is signed as "to I-10" from City Park Ave (because of the no-left-turn ahead) and "to I-10 West" from the Metairie side.

Also, what's the reasoning behind this little guy? https://www.waze.com/editor/?zoom=8&lat ... s=63675043 Is that to trick the oft-ignored turn restriction?

Is that something we should consider using with other stubborn ones, like Carrollton at Palmetto and at Earhart?

Well, I did those as Pontchartrain Blvd because there are signs...you have to look hard for them though...and specifically for the people who have to navigate through all that but aren't actually going to I-10.

If you're coming from City Park Avenue to the lakebound expressway, you should get the instruction to turn right on Pontchartrain Blvd, and then the next segment they're going to hit is a ramp, so it should give them the "to I-10 W Metairie" instruction immediately after turning.

Those segments have to be named something other than "to I-10" and they can't be ramps, or the TTS instructions are all screwed up. Can you think of anything better to call them? (Somewhere around there, on a utility pole, completely invisible from the road, is one of those black and white vertical signs that says "Julia St". That would really confuse things on the map!)

I kept finding the left turn enabled there, so I eliminated the junction. Even with the turns disabled, Waze still wanted you to make the left. It might've had something to do with reverse connectivity, but at the time, I did this, it worked, and no automatic process could undo it. It's based on an intersection that banished created that eliminates some of the junctions...you can see one if you look at the corner of Terry Parkway and Belle Chasse Hwy.

I made it tiny so that it wouldn't be visible on the client and also so that it wouldn't be really obvious to a newby editor who might feel the need to "fix" it if it was visible. I actually had forgotten about it until last night, which is why I didn't include mention of it in my initial post.

I did the same at Tulane and Carrollton, but I undid it after I learned about the reverse connectivity bug, and there hasn't been another UR there. That may be all that's necessarly to fix those other intersections. (I had Carrollton and Earhart set wrong, because I thought it was a time restricted turn...it's working properly now.)

My logic is that the majority of traffic here is going through here to get to I-10. The I-10 signs are bigger and more prominent than the Pontchartrain Blvd signs, so even if you aren't going to get on the interstate, you're still turning onto a segment that is signed "I-10" or "I-10 E: New Orleans". Unfortunately, unlike interchanges like 610 at, say, Elysian Fields, we can't get full accuracy by leaving certain segments unnamed and have instruction display either "to I-610 E: Slidell" or the name of the road that continues beyond the ramp dependent on where you're going.

I was mistaken earlier--it's a no-left-turn from either direction on Metairie Rd, not just from the New Orleans side. We could either leave it as it is now, which I don't like, or we could name the two segments coming off Metairie Rd "to I-10", which is also consistent with signage and is helpful to more traffic.

I thought about removing the names from those segments entirely, but that isn't workable with the layout of the streets here.

I'll have to check it at Earhart. Have you messed with Carrollton at Palmetto at all recently? The left turn restriction from Carrollton riverbound to Palmetto is in place, but it wanted me to turn left there earlier anyway. I'm thinking Waze needs to rework their penalty system for restricted turns.

What's the reasoning behind these segments? Turn restrictions appear to be such that these could just be a simply two way segments, so am I missing something?

Yes, but your unique variation on what I did makes it "Jason Jct."
