Tools like keepright often indirectly show such cases by detecting the non-intersecting overlapping highways.

OSM Node Density – 2016 Update 9 days ago

@joost: nope. here you go: Code and freshly processed raw data is included. osmnodes-eu.geostatgrid.csv uses keys that are compatible with the grid ids from the pop dataset, but note that their "reference grid" doesn't include cells with 0 population.

OSM Node Density 2014 13 days ago

@goclem: In this visualization (as well as the updated one) from 2016, there is no minimum number of nodes in a pixel. The maximum depends very much on the zoom level you're looking at. Frederic's analysis from 2013 may give you some more insight into what absolute numbers one might have to expect.

Validation feedback can provide important social affirmation 14 days ago

@dekstop: Thanks for the additional explanation! It's much clearer now.

Validation feedback can provide important social affirmation 14 days ago

reduction of the hazard rate to 80%

Can you please explain (to a non-statistician) what that means exactly? For example: Does it mean mappers who received feedback, were ~20% more likely to continue mapping compared to those who weren't messaged?

Sorry, currently, there's no updates! :( I've been looking into doing updates via Overpass' augmented diff, but I've run into some issues which need to be resolved upstream before it can work (see links in The alternative of reprocessing the history dump every week or month is currently also not really an option because of my limited computing resources.

@Robot8A: Unfortunately, that's also one more thing on my to-to list.

@Joost, probably not too hard. There's already a ticket on github for that, where any progress will be documented:

30'000 different IP adresses per each day of the weekend [accessed] Overpass API

yep, that's in line with what I'm seeing in overpass turbo's recent access logs (see the chart below; the pre-event base level is around ~500 visits per day ^_^). The bulk of new users seems to come from the US, though.

@Jojo4u: You're free to do everything you want with the generated charts as long as you comply with ODbL's minimal requirement for produced works, i.e. citing OSM as the data source. A link back to this blog article and/or the website is very much appreciated, though. :)

Funny idea, that could indeed partially improve the issue with split ways. Still, a proper solution would have to track the actual length and/or area of the respective objects.

Oh, I wasn't aware of trolleway's implementation. Thanks for pointing it out!
