Road closure in Winter (Alps)

[svx-biker]

I've found other threads more general about road closures and there's no way yet.

Especially in the mountains there are various major roads closed for a period of months due to snow (in German: Wintersperre). I've recently found Live reports here

(initiated one month ago) closed due to snow ...

Is this an automatic report and how can it be set? Or is this a user reporting over and over again?

This is probably auto mated (capability through rss feeds with geo reports, and through a system waze is developing for third party data), though this is just a report. No traffic alert so unless someone has physically disconnected the road in the editor, this will not keep them from being routed through here.

Until they give us some timed road closure system, best to disconnect this per the wiki.

I disconnect roads due to winter multi-month closures. I try to keep a wiki page updated so other local editors can reconnect it. I also rename the road adding some verbiage about the closure to the road name.

Why don't you try and see if you can get some sort of integration with your local service , ie - highways agency / traffic scotland , other than that I'd disconnect the road and mark it no entry

Marking it is no entrance, which will read "Unknown" in the next editor version, has no effect on routing. Disconnecting it is really the only surefire way.

Yeah but if you disallow turns it won't let you onto it , no ?

For fairly short routes, or routes for which there is a nearly equally distant or time route, yes. But if Waze has to go a significantly longer route, it may determine that breaking a turn restriction is a lower penalty. You can try it and find out! The timing to get the map update to see if the turn restriction works and disconnecting the road completely are the same, though. If the turn restriction doesn't work, you've got to wait another map cycle to test again.

I'd disconnect the road anyway , I'm just saying would dis-allowing a turn not do the same job and save you the time and effort of re-connecting it later on ?

That depends on your definition of "effort." This is how I see it:

A turn restriction change for a 3-way intersection involves selecting each segment and restricting the turn from both. With a click to save, that's 5 clicks. For a 4-way intersection, 7 clicks. For a disconnect, you select the segment to be closed, click-drag the end point away from the intersection and save. That's 3 clicks.

Does it "look" better with the turn restriction method because the road is still there and all? Yeah, I guess so. But with that junction in place, you still give Waze the potential to route over the "closed" road. With a disconnect, there's no chance at all because the connection is broken.

It's your call.

As AlanOfTheBerg has stated, disconnecting is the only 100% for sure way that Waze will not route that way. Turn restrictions are a penalty in the routing not a definitive no. So turn restrictions are not 100% effective in stopping a turn from being routed.
