Rückzugsorte – Map of areas in Berlin which are the furthest away from a street
- looperhacks 7y agoNice idea! This seems to ignore smaller streets though, why?
- Freak_NL 7y agoProbably because those are mapped in OpenStreetMap as service roads (which includes alleys, driveways, parking lanes, etc.). The author of this map seems to have queried all roads in Berlin from Autobahn down to residential streets, and left out service roads, and bicycle and foot paths.
- sedlich 7y agoYes like Pfaueninselchaussee. A street but with very low traffic.
- gillesjacobs 7y agoNice work! Would be nice if the tooling could be open sourced so it can be applied to any area of interest.
- odiroot 7y agoHah! I live inside one of these bubbles in Mitte. The truth is the grid of Altbau (pre-war) buildings is great to live in, especially if you don't share the flat and can utilise the "back" room as a bedroom. But pretty much most side streets (at least in the West) are super quiet -- thanks to speed bumps, narrow lanes, treeline and wide sidewalks. EDIT: Also many points are in heavy-industry areas (like Westhafen) so being far away from the street doesn't change much.
- eru 7y agoCentral London (of all places!) also has really quiet and walkable side streets.
- cnj 7y agoNice! If I re-engineered your algorithm correctly, it tries to find the single largest circle within a grid of streets. This, unfortunately doesn't work well for a river that isn't frequently broken up by bridges. E.g. the whole area of Treptower Park, Insel der Jugend, Stralau and Rummelsburger Bucht doesn't have a Rueckzugsort next to the water (there is only a big one in Plaenterwald for that whole part of the Spree). Nice work, though. I'd be interested in a version of this that maximizes walking or biking time without crossing streets!
- anc84 7y agoIt's a cheap and hand-wavy, yet titled impressively piece made by an artist so don't expect anything too sophisticated ;)
- terminalhealth 7y agoWorking with circles seems weird. I would have computed a Voronoi tessellation with Fortune's algorithm (also n log n) and colored the result with OpenGL triangles. Even better would be to estimate traffic density of the roads based on road type and some measure of centricity/connectedness and also weight the resulting values with that. A small central spot sourrounded by small streets may be calmer than a large peripheral one right next to a high way.

- mewwts 7y agoThis is so cool! Would love to have this kind of information before I rent or buy an apartment.
- JorgeGT 7y agoIf you live in the EU, there's an European directive making noise maps mandatory: Member States shall adopt the measures necessary to ensure that no later than 30 June 2012, and thereafter every five years, strategic noise maps showing the situation in the preceding calendar year have been made and, where relevant, approved by the competent authorities for all agglomerations and for all major roads and major railways within their territories. END Directive (2002/49/EC) There's a basic online viewer here: http://noise.eea.europa.eu/ http://noise.eea.europa.eu/ but the GIS data is available here: http://cdr.eionet.europa.eu/ http://cdr.eionet.europa.eu/
- lazyjones 7y agoUnfortunately, legislation in some countries (at least 1, Austria) prohibits use of this data for commercial projects.
- JorgeGT 7y agoAh, that's unfortunate indeed. In my city that data is CC-BY 4.0.
- ChuckNorris89 7y agoIs it me or is Austria most paranoid country in Europe in regards to privacy? IIRC, dash/helmet cams are also not allowed here due to privacy, which is crazy. A friend of mine was hit by a car while riding his bike and now has to fight the driver in court to get justice since there were no witnesses. A cam would have made a night/day difference.
- NapoleonIT 7y agoGreat work!
- m1cl 7y agoguys, don't post anything about Berlin. This city has nothing to offer.
- TheComet 7y agoYou are completely wrong there Berlin is one of the best cities in the whole word. Very friendly and mostly free of neonazis. There is a great place to dance ABBA songs called Matrix, just under the subway station near Friedrichshein Is one of my top favourite places to dance in the world, together with the famous Propaganda, or PPG , like the young people call it, in wudaokou, near the forestry university
- aap_ 7y agoI have a feeling he's from Berlin and doesn't want more people coming here.
- iamsaitam 7y agoeither that or he's a german from some other place..
- ivan_gammel 7y agoIt is known that Germans have weird taste for life, preferring cash to digital payments and not really understanding what does “global city” mean (just kidding here). I’ve lived in several German cities and Berlin does not differ much from others, except that it’s much less boring and probably much more English-speaking. The railways are as irregular as in Hamburg or Cologne, the beer can be as good as in Munich and you can get in some places as good Maultaschen as in Stuttgart. Berlin airports are shitty, too much multi-kulti on Alexanderplatz for some people and no one says “Servus” or “Moin” - but that’s a feature, not a bug of this city.
- martin_a 7y agoSorry to disagree. Berlin is the shithole of Germany and everybody, except people from Berlin, agrees on this. This opinion is more uniting than the fall of the Berlin wall or anything else in this country. It's a town where nothing really works (airports, anyone?) but people from Berlin think that's the way it's supposed to be and that it's somehow "cool" to be this way. It isn't. Any other European capital is really nice or at least tries its best to be nice, Berlin is just "meh, don't care". Financial power is not concentrated there, nor is industrial power. Companies (and what you might call "startup") have some outposts in Berlin because it's chic to have something in Berlin. It sprays the scent of being wealthy (enough), while the real major cities are in the Ruhrgebiet, Hamburg, Munich, Stuttgart (in loose order) and those are the places big companies have their headquarters and never really thought about moving to Berlin. Tourists like Berlin because it's so shabby, but that's about everything that city got. It's some strange kind of fascination for disgust and decay that attracts the people. Germans don't like Berlin. It's hyped for nothing and you can find better jobs and better places to live all over the country. Right now I'm kind of living in the middle of nowhere in south-west Germany near the French border and I got 100 MBit/s internet connection, so not even that is better in Berlin.
- hannob 7y agoNice idea. Though looking at my area a few of the larger dots are inaccessible industrial areas. Not exactly what you're looking for. Wonder if that could be made more intelligent.
- jglauche 7y agoNice idea. I'd like to see something applicable for other cities (via openstreetmap?) to explore possible partially remote areas where I could be living; along with the possibility to hook it up with more data. Background: pretty bad case of asthma, car exhausts being one thing that makes things worse.
- viach 7y agoWould me interesting to compare this with a map of criminal activities statistics.
- lazyjones 7y agoAnyone interested in building a "livability" map with noise, air pollution, traffic, demographic indicators, proximity to nuclear reactors, flood and other natural hazards risk etc. or anyone doing this already?
- ovi256 7y ago>proximity to nuclear reactors Don't forget proximity to vaccines! On a more serious note, a coal plant (like there are plenty in Germany) will spew 10x more radionuclides in the air than a nuclear plant for the same amount of produced electricity. So why aren't you avoiding coal plants rather than nuclear power plants again ?
- yorwba 7y agoCoal plants are already covered by air pollution measurements.
- coddingtonbear 7y agoThe point being made is that a properly funtioning nuclear power plant emits very little radiation when compared to a coal-powered plant. Coal power plants, even with emission regulations, are very dirty as far as radioactive emissions are concerned.
- Tepix 7y agoThe risk of cancer for small children is doubled near a nuclear plant, see https://www.bfs.de/DE/bfs/wissenschaft-forschung/ergebnisse/kikk/kikk-studie.html https://www.bfs.de/DE/bfs/wissenschaft-forschung/ergebnisse/...
- dspig 7y agoAs it’s small numbers and small distances involved, I wonder if the risk is really from parents working at the plant, or if they controlled for that.
- mkl 7y agoI can think of computationally intensive probabilistic algorithms to find these circles (e.g. hill-climbing by randomly mutating circles), but is there a way to guarantee optimality? I.e. find the absolute largest circle inside a given polygon. Is there any information about how these particular circles were generated?
- yorwba 7y agoThere appears to be an O(n log n) algorithm: https://stackoverflow.com/questions/4279478/largest-circle-inside-a-non-convex-polygon/46867645#46867645 https://stackoverflow.com/questions/4279478/largest-circle-i...
- tempodox 7y agoVery nice how the resolution increases when zooming in. This should exist for every city.
- whoopdedo 7y agoProbably should have included railroads as well.
- bkfh 7y agoNice! Berliner here, living very closely to a large green bubble in Neukölln (Tempelhofer Feld)
- amelius 7y agoCan someone mathematically formulate the exact problem that is solved here?

- dima55 7y agoIt's pretty simple and fun to compute these for your own use cases. Openstreetmap data is really useful here. One implementation: http://notes.secretsauce.net/notes/2015/05/06_poles-of-inaccessibility-in-the-san-gabriel-mountains.html http://notes.secretsauce.net/notes/2015/05/06_poles-of-inacc...
- gerogerke 7y agoThere's a big bubble right over the airport Tegel (TXL) hwich I would consider no place of silence ;)
