What does "level" mean on the road properties?

[jasonh300]

Just to add to this, a Level 5 over a Level 0 is exactly the same as a Level 1 over a Level 0, or for that matter a level 7 over a level -3.

The reason there are so many levels is there are spaghetti interchanges in places where you may have several different levels of roads, and you need to keep them untangled.

The easiest way to do it is to keep all ground level roads at 0 and then adjust as needed for overpasses and underpasses.

Road type should NOT have any bearing on levels. Geography/altitude alone should matter. Otherwise everything should just be level 0...

In my area, when two segments cross over/under each other, I set both of them to non-zero values. In the simplest case, 1 and -1. (If the roads continue, subsequent segments revert to 0.)

As a result, when I come across a situation in which segments cross, if either of them is already non-zero, I know immediately to leave its value alone.

That's a bad way to do it, if a road is grond level it should be zero if you have a bridge then it'll be 1 if you have a bridge over that then that road will be 2, if there was a tunnel under all these roads then it'll be -1.

I hope I can be an area manager very soon as I have found a set of roads that are set all over the place.

An example of the problem
a highway that's set as 3
a bridge over that set 5
the onramp to the highway is set at -3
the other end of the bridge road goes to 0 then ends up at 1 at an intersection.

The levels are all over the place is really bad editing really.

The poor client must have a hard time trying to work out what is happening because if you travel over the bridge you go from a lvl 5 hight road straight into a -3 tunnel to enter onto a lvl 3 highway.

Everything but the bridge road in all ground level, see the problem.

and all these roads are locked so can't be edited, it needs to be fixed bad and it's been edited by a lvl 4 editor that is an AM as well I think so won't be able to do anytghing about it unless I can be an AM.

Don't waste your time... AFAIK, the client does nothing with levels, neither does the current editor. They are a leftover from the old editor.

You've only been a member here for two days. While you're not incorrect, you're really not in any position to second guess the methods of a senior editor. Harling has been with Waze since the very early days, and has been a huge part of the development of the maps and software.

In the two days you've been here, you've demonstrated through several posts that you're very gung-ho about doing all of these things, but from what you've posted, you haven't read much or any of the documentation. At this point, your best bet would be to sit back and observe and learn a little bit before you begin commenting on the work of senior editors.

Um... if a single mile-long segment of interstate starts above a valley (and passes over a couple roads in the valley), then the ground rises and surface roads cross over it, and then it goes underground into a tunnel as it enters a city... what should its level be set to?

Road level is both relative and arbitrary. The convention of leaving everything at "0" when the road network is flat--regardless of ground level--and changing it to non-zero whenever a road crosses over or under another, is a strategy that has saved me a lot of time in scenarios like the above. Consider a very long segment of interstate, and a road that crosses it. If I change the level of the long segment, is that going to mess up the levels at another over/underpass? If the level of the segment is 0, that tells me (in my area anyway) that I am free to change it, without having to scan its entire length to make sure it won't "break" anything else. If it is non-zero, I know that I need to leave the long segment where it is.

I try to keep the higher value road type at a zero level due the the fact that the those roads most likely have the longest segments and can have other roads pass over and under it as it goes. There are some crazy interchanges here in Connecticut, so it may not always be the case, but as a basic rule of thumb it works. I've actually had to use pipe cleaners to recreate a few of them to determine levels for Waze.

I didn't take any... But have another major interchange to do in the near future, so I'll try to grab a photo then...
