Map of turn restrictions

This map visualizes turn restrictions and indicates errors and warnings. It is intended to guide you in increasing OpenStreetMap’s routing quality. The map isn’t perfect but it is stable enough for the most of us ;)
There are problems in Internet Explorer prohibiting the loading of restriction data for some browser versions. I checked IE 9 and IE 10, they work for me. Firefox, Chrome, Safari work fine.
Turn restrictions are fetched from Overpass-API, which is updated every few minutes.
Have fun!

Dear Zartbitter,
Why the following restriction you count as incorrect?
restriction:agricultural=no_left_turn restriction:hgv=no_left_turn type=restriction
Error: — relation with more than 1 restriction tag
Should I bifurcate it to two separate restriction? (I think it would be redundant.)
Thanks.

@ AlexTheTux Yes, the map counts restrictions with more than one tag named restriction or restriction:* as an error. I think you’re right, I’ll change the rating to warning if there are multiple restiction tags. Just wait until tomorrow.
Can you tell me the relation id for testing, please?

@AlexTheTux: I’ll fix this tonight. Multiple restriction tags will be rated as an error only if the values are different (e.g. restriction:hgv=no_left_turn and restriction:psv=no_u_turn). Thanks for your input!

Thanks for the excellent tool. It’s helped me spot and fix several broken turn restrictions near to me that have been accidentally broken by subsequent edits.
I wonder whether it might be possible to allow it to be used on one zoom level further out than at present if you’re only looking for errors and warnings? Hopefully errors and warnings only constitute a relatively small portion of the data.

@Gregory Williams: Thank you!
Now there’s a gear wheel on the bottom right. It opens a small preferences dialog where you can set the minimal zoom level from 10 to 15 (default is 14). But this preference settings aren’t stored. After reloading the page the default values are used again.
Another change: Permalink now uses overlay settings. E.g. if you deactivate turn restrictions without errors/warnings the permalink reloads the page with the overlays activated/deactivated as they where.

Sorry. a typo: minimal zoom level can be set to values 12 to 15.

This seems like a very nice tool. It helped me find a couple broken turn restrictions. However, it seems to list many “errors” that I can’t interpret. For example, this relation is said to have the error, “to not properly connected to via.” The node labeled “via” is clearly part of the “to” way so I don’t know what this is getting at. Thoughts?

@sat
yes, the “via” node is part of the “to” way, but the “via” node has to be the first or last node of the “to” way. Otherwise it is not clear what direction is meant - “to” can be 2 directions if the “via” node is somewhere in the way (from “via” to the first node of the “to” way or from “via” to the last node of the “to” way).
Best is to split the “to” way at the “via” node. You’ll get 2 ways, only one (the right one, of course g) should be the “to” way in the restriction.

Hi! Wonderful tool! It helped to fix about 10 problems in restrictions. But sometimes restrictions with problems (either warnings or errors) are off-screen, sometimes hidden under multiple restrictions circuit. Therefore, it would be helpful, if message “n warnings/errors” would be a link and it would expand to a list of restrictions with problems when clicked. This way it would be much easier to hunt problems.

Very interesting map, though there is situation where it gives a false positive:
there is a way that is oneway (oneway=yes) but not for bicycle (oneway:bicycle=no)
turning left into this way is forbidden, also for bicycles
This tool claims that relation has a problem ““to” member 242368428 forbids to enter oneway in wrong direction”

@Mateusz Konieczny:
Your turn restriction is true for cars, too. And for cars the error message is correct.
BTW, the turn restriction is checked without using an artificial intelligence to recognize every access condition. If there’s a limitation to only one kind of vehicle, this is not supportet by this map, yet.

Great tool !! Thanks
