Judah street is currently not divided. And I know there are lots of issues that arise when dividing the roads. But the problem people have today with Judah is that people get routed to the wrong side of the street, and then they send URs about being unable to turn left at their destinations. And since few intersections on Judah allow lefts…
So is that a reason to divide it? Or is it not worth the issues that dividing causes? Might it be better if the intersections are bowtied?
Bumping this up…the core issue here is the N-Judah dividing the road in such a way as to make a difference routing to one side of the street or the other.
If I recall, someone recently looked up the California Driver’s Handbook and confirmed you can cross a solid double yellow line to pull into a driveway. Therefore there is no need to split the road unless there is a barrier I am not aware of on Judah St.
The barrier is the N-Judah tracks, which are non-driveable in between the intersections from 9th to 19th Avenues. There’s a raised area in the middle of the road where the trains run. West of 19th, it’s shared road between the trains and cars.
You can check the street view to see what I’m talking about.
It’s always good to post a permalink for those less familiar with the area.
I see what you are talking about. I was looking at another part of Judah that was not raised (another reason to include a permalink). 
I think you have a good point if essentially this entire section of road has a barrier for many blocks with no left turns allowed. As well there are many intersection with no cross traffic across the tracks.
I think the only solution is to divide the street where the road is raised and no left turns are possible. After all, navigation is the purpose of Waze and without dividing the road it leaves you at a point that is very difficult to solve visually on the road. Let’s get a few more responses on this before we finalize the decision.
Point taken re: permalink. I’ll do that in the future on these sorts of topics. Speaking of which, the segment in question is longer than the one in your permalink. It’s really this whole portion:

Exactly. 
Also:
+1 for determining this is likely the best solution to the URs
+1 for not just making the change to the map without getting feedback in the forums
Thanks for the +1s. So…nobody else is chiming in. What’s the next step?
Give it a few days then we can likely move forward.
It’s been a week. Is it time to go ahead?
In the Washington forum, we’re talking about 5th Ave in Seattle which is a 1-way divided road (same direction) on either side of monorail pillars. The thing which is difficult here is that there’s no easy way for Waze to guide the driver to near or far side of the divided street. Not sure if they will be visually separated enough in the app to make it quick and easy to see. I’m not sold on how to handle the Seattle situation. Sounds like Judah split may be more straightforward.
Yeah, the 5th Avenue situation is far more complicated. The monorail itself, plus the narrow street with tall buildings on either side, gives a marginal GPS signal, so there’s more error. Judah is about twice as wide, with 2-4 story buildings on either side, and nothing above. And the median is 3-4 times as wide as the monorail stanchions. Judah should be easy in comparison
Now if we could just have Waze recognize altitude as well, it would be able to handle cases like the Stockton tunnel, and maybe even the Bay Bridge around Yerba Buena Island.
There is a procedure (probably not documented yet), that helps to split a two-way road (unless there is a script I don’t know about).
A single road will have addresses on each side of the road. Once you split the road you cannot move addresses from one segment to another (unless they are joined physically).
I have found the following.
Start by drawing a road from the middle of the segment to be split out to some point without connecting to another road. Delete that new road. This creates a junction in the middle of the segment to be split.
Disconnect the two segments at the middle and stretch the two segments the length of the original road on either side of the median forcing the split.
At one end of both new segments attach them together, like a “V”. This will enable the “Edit House Numbers” interface to edit both segments as if they were one road.
Identify the houses on one side of the median and make sure the stop point for those houses are linked to the more appropriate segment. If not then move the stop point to the other segment.
Complete this for both sides of the road and save changes. You may find it necessary to force the changes.
When complete separate the two segments and continue with the next segment.
When all segments have been split, reconnect them properly and with the correct turn restrictions.
OK I’ll be able to do this for only a portion of the road unless you downrank it all to 3.
I reset everything you put in your permalink to level 3. Go for it and let’s see how the procedure works out. If it is fully successful we can add it to the Wiki to save addresses with splitting.
Thanks for lowering the locks, but I’ll also need the cross streets at 14th, 15th, and 19th lowered or I can’t fix their intersections with Judah.
I did put in the mid-block nodes thus far, so that’s a start.
Done.
OK, I think I have it right. I’d appreciate a sanity check, though.
Note that 15th and 16th don’t permit crossing Judah at all.
House numbers look great from the ones I checked. Looks like a fine job.
I did notice 17th to Judah says no right turn, but does not match the visual. Maybe just a turn restriction error?
Yup I missed that, which is exactly why I wanted the extra set of eyes. Good catch, and now it’s fixed.
