Neighborhoods with Limited Access to Streets
- geerlingguy 6y agoJust wondering, why is there no data for the USA? [edit: also, Russia, most of Europe, Australia, and many other regions. Maybe I’m missing something on mobile?]
- wmf 6y agoYou're not missing anything; those countries are completely white on the map. "Limited access to streets" is kind of a euphemism for what we used to call "third-world slums" which aren't really a problem in developed countries so those countries probably get a lot less study. I saw an interesting paper a while back about computing the minimum number of shacks to tear down that would allow putting in new streets/utilities to provide access to every structure. It's a very different mindset from urban planning in the developed world.

- cblum 6y agoI looked at the city where I used to live in Brazil and most of it is red. It doesn't make sense. It's a pretty normal city not unlike a first world one. I'm not sure what they're really measuring there.
- timwaagh 6y agothey are most likely purposely being left off the map since theyd probably show up red in some areas just like ukraine and belarus which would imply the west has these 'slum issues' wich would be kind off ridiculous. this would not support their case.
- scythe 6y agoConsidering the lack of red in both El Salvador and Russia, it seems pretty clear that the countries colored in are simply those the researchers chose to study. Nobody believes El Salvador has no slums and nobody is trying to make Russia look good. Exactly one impacted region is depicted in North Korea, in the Kaesong region -- it's easy to see why from the map.
- timwaagh 6y agoi dont have an explanation for excluding those. except russia. a huge piece of red there would be a very easy giveaway something is wrong. however the authors can do a specific thing for a specific reason and still leave out some other places. the idea to leave out the us, the eu, brittain, norway, iceland, australia, new zealand, japan, etc in addition to those you mentioned can't be counted as mere coincidence. that's deliberate. the fact that the method is very flawed is painfully obvious from other things as well. those large very red swathes of lands in Niger and mauretania are a stretch of sahara, not some massive slum. i hope the authors will not be discouraged by their failure. next time i will hope they will include the west and not paint the desert/tundra/etc red.
- scythe 6y agoThere's quite a bit of red on Puerto Rico!
- soared 6y agoAfter 2 devastating hurricanes in less than a decade their infrastructure is pretty poor. I visited 1 year ago, before the last hurricane, and most roads were good but they still had downed trees and destroyed buildings everywhere. (Countryside and San Juan, their city).
- Anon4Now 6y agoThere is. You have to zoom in on a region. I zoomed in on Portland, OR and found areas of light pink. I'm more curious why the Sahara is considered a neighborhood with limited street access, but the sparsely populated Oregon High Desert (SE Oregon) is not.
- agustif 6y agoNomad people consider all sand their roads, and since their home moves with them the acceess is pretty neat?
- lazydon 6y agoI checked for red spots in regions in Indian that I am aware of. The big ones mostly are cantonments / areas reserved by military and wild life reserves.
- rmujica 6y agoMost red zones in Chile are national parks/private ecological reserves

- diziet 6y agoI checked the neighborhood I grew up in Ukraine, that had great road access. It was orange and red. I think the methodology is too aggressive.
- legerdemain 6y agoIn central Donetsk, which is what I'm familiar with, the "neighborhoods" they classified as having the worst access to streets are a steelworks, a chemical plant, and a coal mine.
- jlg23 6y agoProviding some link to how this data was "collected" would be tremendously helpful. Looking at https://millionneighborhoods.org/#11.46/29.7099/-9.7936 https://millionneighborhoods.org/#11.46/29.7099/-9.7936 a private beach resort has "high access" while the few holiday mansion ghettos that dot the beaches just north of it have "low access". In reality all the same layout: big entrance, villas on a grid, road access to each house. And again further north all has "high access" despite there being only one road, wide enough for just one car and potholes I now know by name. Even locals avoid that road if they like their car... and to reach the "high access" coast side, one even has to get off that road and onto gravel roads (4x4 advised).
- londons_explore 6y agoPlaces without cars don't really need streets. If you replace all streets with footpaths, you can pack houses in much more densely, making walking a viable option, rather than needing lots of cars. Streets are inefficient use of land, especially if most people can't or don't want to use them.
- zozbot234 6y agoHow do you easily transport cargo without accessible streets? Also, what about longer-distance mass transit. Narrow alleyways and footpaths work well at the scale of an urban block, maybe a bit larger than that - but streets are quite important to the bigger picture.
- zokier 6y agoNevermind cargo, but how about ambulances and fire engines?
- Fricken 6y agoEntire civilizations have operated without wheels. You guys are just arguing on behalf of what you're familiar with.
- zokier 6y agoOperated, yes. Note, past tense. And people died like flies and whole cities burnt down.
- tonyedgecombe 6y agoI'm pretty sure it's sewerage and clean water that stopped people dying like flies, not streets.
- Fricken 6y agoCities with streets have burned down as well, and as far as I know everybody still dies, as do flies.
- topkai22 6y agoA news article linked by U. Chicago gives some more context: https://nextcity.org/daily/entry/mapping-tech-could-formalize-settlements-for-one-billion-people https://nextcity.org/daily/entry/mapping-tech-could-formaliz... It looks like the creators are focused on detecting issues with property rights more than transportation.
