Thanks Richard. I took it to mean, “you’re acting like a child complaining about this”. I appreciate the clarification.

(Ugh. I should have previewed that comment before posting. And apparently I can’t remove it.)

Ah, these youngsters.

I’d like to see something more substantive from OSM leaders like Richard and pnorman rather than dismissive ad hominem attacks.

In this day and age, you can no longer make jokes like this. If SomeoneElse hasn’t figured that out yet, they will be in for a big surprise when they get caught on video making a microaggression and lose their job over it. SomeoneElse should be open to the fact that the man in the photo might have been seriously offended at the presenter making a joke about him when he (possibly) wasn’t doing anything wrong. Look at it from his perspective.

@Zverik is delusional if he thinks he speaks for “everybody here”. You lose a portion of the population when you advocate for unequal treatment and exclusion. Why not strive for truly level playing field and not alienating people. Do you think you’ll actually attract more people to your cause with statements like that?

I brought the following video to the attention of the SotM-US organizers:

They couldn’t have cared less about it and made it clear that they were biased towards sexism against men being acceptable.

It was at that point that I stopped caring about diversity in OSM. You lost an ally in me.

I have some scripts cobbled together to pull down different regions and process them individually and upload maps to github on roughly a weekly basis. The repo (mentioned above) is: https://github.com/b-jazz/sharp-turns-onto-ramps

My count of worldwide nodes that were called out as of 2017-09-03 is 235,846.

I was thinking of setting up regional map roulette challenges to see if we can get some movement on reducing that number. I’ve never messed with maproulette.org before, but it doesn’t seem too hard to do. Would that be a good idea? If anyone reading this has thoughts, I’m open to hear them.

I believe that turns of 1-80 degrees, not 85, get called out. At least that’s what I see empirically looking at the results (it’s not my code, I’m just messing with turning the raw data into maps). And I agree with Hjart that the example map should be left alone and added to the exception list instead of twisting things around to make it not get triggered by this particular validation. That is likely an unintended consequence of the validation. If there is a physical triangular island or painted lines, I would do something like the above, but typically I leave these alone and add them to the exception list.

Sorry, yes, I should have mentioned that the URLs aren’t active and clickable. I’m not sure if that is possible with the geojson rendering that github/leaflet/mapbox does. If someone knows the trick, please let me know. I gave up after a bit of searching, and like you noted, at least you can copy/paste the URL.

I went ahead and changed the URLs to be “…/node/323277879” instead of “…/edit?node=323277879”. I prefer those as well.

I’ve started a new github repo for the maps that I generate:

https://github.com/b-jazz/sharp-turns-onto-ramps

When you wrote your comment, the Denmark map was 23 hours hold, so I came back later to make sure I have the latest greatest. You’ll now see (if I remember) the date of the map in the github comment.

I’ve also implemented a rudimentary “exceptions” file in that repo that can be updated with node IDs to ignore the next time I run my map generating script. Feel free to edit and submit a pull request.

As always, let me know if you have any problems/questions.

I’ve been playing around with osrm-extract on daniel-j-h’s sharp turns validation branch and parsing the input and making maps. I don’t have the compute horsepower to run the whole planet, so I’m looking at smaller countries in the meantime while I work on alternative ways to process chunks of the planet at a time.

Here is an example map that I’ve generated of Denmark. I’ve kept the lines that daniel-j-h had and I’ve added a starting node marker (‘s’) so that you can see the direction through the node that is the problem. I’ve also included a URL to edit the problem node when you click on the marker so that you can easily start editing. (Note: the marker is for the first point, but the actual URL is to edit the second/middle point that has the sharp turn associated with it.) I spent far too many hours zooming in on one map and then zooming the editor/iD map trying to find the node in question. This should be a lot easier.

If you see problems with how I’ve generated the map, please leave a comment here or contact me directly. If you have some small (country-level) maps that you’d like me to process in the short term, let me know.

Are there plans to update this on a regular basis. I try to poke around a clean up a few of the sharp turns when I have some time on my hands, but it is getting to the point where I run into ones that I’ve already updated, but they are still on the map. I’d love to see daily updates if it isn’t too difficult.

I’m also curious at how things have changed with the map since you first started the project. There were ~30,000 at the start. I’m guessing the number has dropped since then (partly due to re-jiggering the methodology and partly due to people cleaning the data). But it would still be interesting to see how effective your project has been.

This is fantastic. Thanks for the great analysis that will help serve to make OSM better and better. I’ve been cleaning up some of the ones in my area.

It would be great if there were a way to tag false positives so they won’t continue to be tagged in the future.
