[UPDATE]Segment Length

This page also states: "There are no system operation issues that require limiting the length of a segment."

Waze now states that 100 km is the maximum length of a segment. And states that this is necessary due to system operation issues. Longer segments gather too much information. Users have found that the waze maintenance bot adds junction nodes to very long segments.

EDIT: The source for the 100km limit is this staff post made 05-Nov-2015 in the GC forum.

Sounds reasonable to me. (I must admit that it irks me to add nodes to segments over 10 kms long and question whether long segments really require more resources in the client. But there are other more important issues to worry about, so I would rather get these changes made than debate what the practical length limit should be.)

My current understanding is that segments in excess of 100km can exist, but the are subject to detection by waze maintenance bot which may add a node to divide the segment in two. The information in the GC thread is not anything more than this. A question was raised as to why a junction node was added on a segment and the last editor showed as waze-maint-bot. The answer (corrected after some typos) was that the maintenance bot scans the database for long segments and the maximum length is 100 KM.

Are we going to make these changes to the wiki?

You should post a link that we can't access. :D

Is there any to share that staff comment to the rest of us? So we can see the official word? Also, I recall being involved in this exact covo in the US SM HO a while back. We tried to see who had the longest segment with no breaks. I want to say that there were some that hit or exceed 62mi/100km.

Hi, Voludu2,
I'm guessing that things have changed since this thread began, but I can edit all properties of segments that are partially outside my editable area, like name, elevation, lock, and even house numbers outside the area and endpoints for dead ends. If the road is connected to another outside editable area, it can't be disconnected, but that makes perfect sense, because disconnecting one road is a change to the other roads.

Is that your experience too? If so, it seems to me that the second bullet point in the "Too long" subsection should just be removed.

I tested a few PS that were less than a mile long, and that's what my previous post was about. Today I tested this segment, which is 10 miles long, and about half of it is out of my area: https://www.waze.com/editor/?env=usa&lo ... =501925669 I could change name, elevation and lock, but since it's a railroad, there were no HNs. I also tested this PS, which is 3.4 miles long, but only a few hundred feet are within my editable: https://www.waze.com/editor/?env=usa&lo ... s=85196127 I added a HN to it about 3 miles outside my area.

I made a 99-km-long freeway extending out into the Atlantic off Hilton Head Island, SC. I could rename it, lock it, raise it, SL it, redirect it, bend it and lengthen it up to 100 km :) I deleted it, but feel free to do the same test if y'all like.

I propose this replacement text. If there are no objections. I will ask the global wiki moderators to approve it.

User:Voludu2/Segment_length#Too_long

That looks good, but I think the statement about Waze bots may also be outdated. If I try to make a segment longer than 100 km I anyways get a save error that says the segment is too long.

If this is the same experience that others have, I would propose that the first sentence instead read "It is not possible to save a segment longer than 100 km in the Waze Map Editor."
