It's like KittenWar for urban spaces
September 28, 2011 1:51 PM   Subscribe

Which place looks safer? Which place looks more unique? Which place looks more upper-class? MIT is crowdsourcing a "perception network" to analyze people's subconscious judgments about urban spaces. Preliminary results for Boston, New York City, Vienna, Salzburg, and Linz (Austria).

Visual preference surveys are a common tool used by urban planners to gauge public interest in and desires for the aesthetic components of their neighborhood. This PDF is a good example of a summary report and shows the most/least desirable images from a study in Bellevue, Washington.

This article from the Journal of the American Planning Association (PDF) goes into detail about how hierarchical models are used with visual surveys to improve the streetscape of an area.

Also: the Austrian photos have a better picture quality while the American ones look washed out and JPEG artifact-y.

Real-life datapoint: I lived in Salzburg for a year and never felt unsafe. I can't say that about American cities.

My guess: "Safer" is so strongly correlated with "front lawns and/or blue skies" that everything else will be dwarfed.

People like windows, too. Startling how much that seems to matter.

Would be especially interesting to see how an answerer's demographics affected his responses. Do all people find wide open spaces and uninterrupted walls threatening, or is that culturally-influenced?

I had a choice between a free way tunnel and a hospital, so the choice seemed obvious. Although I didn't consider the high risk of infection!

Well of course you didn't feel safe, not with all those JPEG artifacts loose on the street.

It asks for your age and gender if you do a few in a row. I think also pictures with people in them would look safer.

Q: Which place looks safer?

Option One: Some nice apartments with hedges
Opion Two: Standing in the middle of a highway

Gosh, I wonder.

Regardless of the weather in each photo, I was looking for sidewalks and residences, as opposed to creepy alleys and expanses of pavement with few buildings around. I've seen that horror film.

Oddly enough, I was unable to rate more than a few when asked which looks more unique, or which looks more upper class. The pictures look the same to me in that context.

Seriously. Originally I was excited by the prospect of what MIT would do. The actuality? Badly biased samples.

I guess it only takes a little more imagination to realize that sampling peoples' subjective response to a minute spectrum of any city's urban realm is just pointless.

Is it badly biased samples, or just that we are actually have very strong opinions on what looks safe or not?
posted by smackfu at 2:23 PM on September 28, 2011 [2 favorites]


I realized pretty quickly that my first impulse was to label whichever one had better lighting as safer. After that, my conscious brain kicked in and I started thinking about how many eyes would be on the street and whatnot.

This seems like a ridiculously bad research design.
But how could it be done? The questions are really complex and hard to separate in a manner acceptable for research. I think some of the relevant questions are already answered in Life Between Buildings, and in Jane Jacobs' work. But there is still work to be done. Maybe it would be a good idea to start with a (respectful) overview and critique of the existing research, so we could like, start on a higher platform.

I've facilitated one of these surveys, and of course there is bias. The thing is, if you ask someone whether they would rather live in mid to high density mixed-use areas with narrow streets and traffic calming and crowds of people everywhere, or would they prefer traditional suburban environs with plenty of turning lanes and huge setbacks, many will in fact choose the latter.

But when you show folks what the former can actually look like, and what the latter often looks like, as opposed to how they may perceive them, that's often a whole other story. Or sometimes it isn't. In my experience it doesn't work well in a vacuum but it works well as a dialogue starter.

Something is either unique or it is not. It is a binary quality. Something can be more or less obviously unique, or more or less remarkably less, but it cannot be more or less unique, just as cannot be more or less infinite. It either is, or it is not. /pedant

"More unique"? I wish I could vote for which photo looked like it understood English.
posted by RogerB at 3:02 PM on September 28, 2011


In one of the "safer" questions my choices were

1. A busy looking street with no markings
2. A quiet looking street with a big zebra cross walk.

I chose 2 but, here's another way you could describe those same pictures

1. Nice looking buildings, fancy-ish cars
2. crumbling facades, chainlink fences, one crappy car.

So, the danger that I was focusing on was, "How likely am I to get killed crossing this street?" rather than, "Am I risking getting mugged or propositioned if I stand on this corner?"

So, my critique of this study is, how has MIT operationalized "safe?"

oneironaut: "... just as [it] cannot be more or less infinite. It either is, or it is not. /pedant"
Actually, there are degrees of ininity. There are e.g. infinitely more real numbers than there are natural numbers, and there are already infinitely many of those. /mathpedant

That's sort of like reading your question and asking whether Australians are 90% dingbats. These photos aren't exactly a representative sample of American spaces.

Nope, it's a fact. There are things which are countably infinite (the natural numbers, rational numbers) and things which are uncountably infinite, (the real numbers).

I take it you've never heard of Cardinal Numbers? There are an infinite number of integers, and there are also an infinite number of real numbers between each integer (and between every pair of real numbers)

I'm pretty much just going to go on believing that it's 90% concrete. You don't get to cherry-pick your photos any more, Yanks! "Oh look we've got this nicely-lit statue, it sprang up out of the ground because of all the liberty." Ha ha, we know what's really going on!

It might be a sort of sanity check, when opening your system inputs to the public you do want something to filter out nonsense responses.

Or it could be the yet another result of the Frogger players of American's recent gains in influence and prestige, they've even got MIT touting their nonsense!

Big trees and lots of cars make a place look safer to me. In reality, these things probably just provide places for evil to hide.

Which website looks more low-brow?

I think my safety perception must be a little warped. First I checked to see if it looked like somewhere I might get shot or mugged. Only two of the bunch I clicked through even slightly fit that category, though many I thought you couldn't see enough of the street to judge well.

Then I thought about how likely I was to get hit by a car as a pedestrian. Several fit there.

Those seem like pretty different measures of safety, though. And if neither picture had fit either "unsafe" category, I didn't perceive any difference in safety.

No, but you see, it's the other way around -- these images are probably randomly taken from Google Street View and processed through the filter of 'the crowd'. 'Safe' and 'Unique' and 'Upper-class' are deliberately ambiguous because they're trying to find out what the definition of these words are, according to you.

As a woman who walks pretty much every where I can and home from work at pretty late at night, I find that both fancy corporate business districts that empty out at 5:00 and upscale, leafy neighborhoods without well-lit sidewalks don't feel all that much safer than the parking lot of the sketchy 24 convenience store across the street from the overpass if you have to walk through them at night.

Or put more succinctly: show me these same locations at 11 pm on a weeknight.

If the landscaping looks neat and kept up and lushly green, I feel safe. I like more people rather than less.

I also got past the lighting and focused on the areas, and found that wide open spaces that looked both unkept (scraggly or dead or no vegetation, broken fences, etc.) and like no one was around for miles made me uncomfortable.

Great idea, badly executed. I can't get a feel for some of these places because of the wicked distortion in the photos. I was hoping for some kind of panoramic or even 3D image.

Being a pedestrian in many North American cities often does feel like being in the middle of a highway. It's not a sampling issue, it's a reality issue.

I avoid driving whenever possible, so I'm sympathetic, but we're not talking about Kansas city here. Boston and New York are both quite accessible to pedestrians. The drivers are the ones to pity.

Places like this or this are just weird to vote on. With most of the pictures you are asking "would this be a nice neighborhood to live/work in?". Then one of these guys come along and suddenly the question no longer makes any sense. These aren't even places where you are supposed to be stationary. It messes things up a bit, because in reality tourists would not often consider the highway a scary dangerous area to be avoided, unless they were inexplicably stopped in the middle of it like this.

I hear "more unique" all the time. It's always obvious that what people mean is that some things are more unlike other things than other things.

Words sometimes carry multiple meanings. "Pedant", for example, can often be read as a convenient shorthand for "person on the Internet who is unhappy that words carry multiple meanings".

I don't have it on me, but I pretty sure there's a chapter in Kunstler's Geography of Nowhere (or possibly Home from Nowhere) in which he talks about visual preference surveys and notes that though people are almost unanimous in preferring mixed-use, walkable neighborhoods with lots of trees, that's mostly not what we build.

As an urban planning student I facilitated one of these in a community participation meeting. The area in question was along a wide road with a grassy median. There was a mix of high density residential and light industrial uses, all with huge setbacks and a pointless sidewalk. We showed them pictures of various streetscapes from around the country. People loved street furniture, landscaping, and buildings closer to the street. That meeting was 5 years ago, and this is what it looks like today.

There are an infinite number of integers, and there are also an infinite number of real numbers between each integer (and between every pair of real numbers)

That's all true, but maybe it can be taken to imply something false, namely that this phenomenon — real numbers between real numbers ad infinitum — is the reason that how-many-real-numbers-there-are is a bigger infinity than how-many-integers-there-are. But on the contrary, there are rational numbers between rational numbers ad infinitum, but how-many-rational-numbers-there-are and how-many-integers-there-are are the same infinity.

I guess I'm contributing to a derail here, but math imposes its own obligations.

Yeah, and there are ways to count off all the rational numbers given an infinite amount of time.

The difference between that and real numbers is that no matter how you decide to order the real numbers, there is always a way to construct a real number which your counting method will never reach, even given an infinite amount of time.

(not that you don't know this, just clarifying why rational and real numbers are different)
