Hi Anthony,

I can sympathise with your sense of frustration. It does feel irritating 
when you feel as though your work is being undermined or broken. I know 
I've spent a lot of time making changes for better routing, only to find 
the same errors get reintroduced.

I think your frustration is misdirected at Andrew here, though. If 
validation tools are detecting issues with some data, someone will 
eventually notice and try to fix it; whether it be Andrew or some other 
editor. In a collaborative, decentralised community it isn't possible to 
stop other editors from making changes in an area.

In this specific case, these errors are a result of problems using the 
iD editor which create "orphaned" relations that would not be used in 
routing anyway. Andrew has indicated that he isn't trying to undo the 
changes that have been added, rather to resolve the validation errors.

I've created a few of these errors myself inadvertently, and it wasn't 
until I started to use JOSM that I realised how much easier and more 
powerful that tool can be. If you are spending hours trying to get these 
restrictions perfect, I'd strongly recommend giving that a try.

Both Andrew and yourself are trying to improve the quality of the map, 
and no one benefits when frustrations boil over in this way. It's better 
to try and work together constructively so we can all spend more time 
doing the fun stuff. :)

intersection, the one you pointed out was pretty simple and was 
functioning 100% correctly before you touched it now it allows u-turns, 
you're pointing out the tiny issue that your validator points out but 
what you don't realize is that the validator doe not see the big picture 
either, its pretty much just pointing out conflicting restrictions which 
are even sometimes left in intentionally, this is not the first time ive 
ran into your edits but I have had enough of it, it takes a lot more 
knowledge and effort to get them working as intended per the rules than 
for you to come along with your little tool, if you personally don't 
know the intended routing and can't see any errors using the routing 
engine itself LEAVE IT ALONE, OSM is only meant to be edited by people 
with local knowledge of the areas, I put a lot of time into what I do 
including random routing on my gps to see what it will throw at me, I do 
not need to be worry about you and your tool coming along to destroy it. 
I am not proff reading this so sorry if there are spelling errors!

Some terminology before we start. To be valid a turn restriction
relation needs to have:

1. A way with the role "from"
2. A way with the role "to"
3. One or more "via" s that can be either a node or one or more ways
4. The members must connect in a way that you can travel

When I say "broken" I mean that one of the rules is broken and when I
say "knowledge" I mean I know what a valid turn restriction should be.

This changeset deleted this turn restriction:

https://osm.mapki.com/history/relation/13905961

which you added in changeset 118257827 and then broke in 118293106 (it
only had a node via member). When I reviewed this one I decided to
delete it because it would only duplicate this turn restriction:

https://osm.mapki.com/history/relation/14044389

which you added in changeset 119769921, if I fixed it.

> <https://www.openstreetmap.org/changeset/120344373> and Changeset:

This intersection had 15 broken turn restriction relation in it:

https://osm.mapki.com/history/relation/13477255
https://osm.mapki.com/history/relation/13477256
https://osm.mapki.com/history/relation/13477257
https://osm.mapki.com/history/relation/13477258
https://osm.mapki.com/history/relation/13477260

https://osm.mapki.com/history/relation/13761161
https://osm.mapki.com/history/relation/13761169
https://osm.mapki.com/history/relation/13761170
https://osm.mapki.com/history/relation/13991446

You broke 14 and added one new broken relation (13991446). While I was
deleting these I noticed that the intersection had some sort of
cross-your-heart thing going on with added ways for turn lanes, so I
simplified it to a standard traffic light box intersection:

https://www.openstreetmap.org/#map=19/-34.76387/138.59277

You can turn right from each arm which means we don't have to have any
no-right turns. There are 4 no-left turns because each approach has a
slip lane. Since it's SA and at traffic lights then there are four no
u-turns to cover that. This is exactly the same routing information that
was there before, but now in a simpler easier to maintain format.

I am not a bot. Just a mapper with overpass, the JOSM validator, the
to-do plugin, and many hours of puzzling over the question of what a
broken turn restriction relation was supposed to be doing.

A couple of years ago I spent quite a bit of time fixing all the turn
restrictions around AU, but I have to keep coming back every couple of
months, as 100-200 newly broken ones get created every month. Mostly
because iD will quietly break existing turn restrictions or let you
create invalid ones and then upload them to OSM. I used to put changeset
comments on the ones that had broken them until a user asked me how they
could stop doing it and I discovered that there isn't a way to do that
in iD.

My fixes should not be changing any routing outcomes as they are almost
all deleting turn restrictions that iD didn't clean up after a mapper
reconfigured an intersection. None of the examples you have pointed to
have changed the routing outcomes as I check to make sure I understand
what someone was trying to map before I fix it.

Hi Anthony,

There are multiple tools out there for finding 'errors' in OSM data and 
many
people use them to keep the OSM data up to date. You might also like to
share the OSM software that you are using on your vehicle GPS as it may 
turn
out that it doesn't handle relations or routing of some situations.

Cheers - Phil

The biggest issue I have with this account is that they don't find 
routing
errors on their own, this person stalks other peoples edits and 
"correcs"
them using knowledge as their source, I find these routing errors 100%
myself in real world situations, I have been editing and using OSM on my 
car
gps for many years, this user edits other users edits based on no 
knowledge
of the intersection at all, having a user like this should put anyone 
off
making any routing edits when this person randomly edits 10 different
intersections in 10 minutes and says they have knowledge.

Hi Anthony (slice0),

Can I suggest the best way to get some resolution is to actually spell 
out
in a changeset comment why you think the change made by Swavu is 
incorrect.
That way everyone gets to learn from 'conflicts'. I also suggest you
restrain your language or you may also face the wrath of the DWG.

PS Swavu is not a bot.

This account is either a bot account or someone that thinks they know 
more
than they actually do, every single time anybody does a routing 
correction
this account comes along and "fixes" it based on "knowledge" from the

let me just say I looked over some of the edit this account does and it
breaks the routing for the most part, Changeset: 120344373 |
