The Zipper Merge and Civil Society

Jon Stewart talking to Drew Barrymore:

JS: To me, the hallmark of civilization, and I believe this on its core foundational level, is the every-other-car merge at tunnels…

DB: Well, they don’t let you anymore, they have cones that say, like, don’t you dare.

JS: No, no, when you get up to that, and it’s like four cars, and it goes down to one. And everybody suddenly, no matter what, Jew, Muslim, gay, straight, black, white, it doesn’t matter, everybody just goes, ‘I’m next,’ ‘No, you’re next,’ ‘Please,’ and it’s like the zipper merge, and it really says, to me, this is why we don’t drink the same water we shit in anymore, because we are a civilized society. That’s my theory.

[Applause]

JS: Who the hell knows.

DB: I love you.

‘A great deal of mischief occurs when people are in a rush.’

Just a quick note to point to this profile of Donald Redelmeier, who appears in Traffic, posted in the New York Times.

Sheer brilliance in the ending:

The idea came to him one day in a hallway at the University of Toronto’s Faculty of Medicine, where he had stopped to admire a century’s worth of class photos showing mostly white men.

“Some people might say, ‘What an old boys’ network,’ ” Dr. Redelmeier said. “But I thought, ‘My goodness, what a homogeneous population, akin to identical white mice, which thereby controls for all sorts of differences.’ ” Thus was born another Redelmeier classic.

Autonomy

Via The Register, a VW designer talks about self-driving cars:

Huhnke said that his group wanted to find out if drivers passengers in autonomous cars would feel safe: “If you have an autonomous car driving … do you trust your car? Do you really press the autopilot button and let the car drive you at 60 miles per hour?” So they conducted a study — and were surprised by the results.

“We created a car with a second steering wheel in the rear where the driver couldn’t see it,” he told his audience. “He or she pressed the autopilot button and thought the machine would really drive without human help. Someone drove in the rear seat without being recognized by her or him. Well, you couldn’t imagine: after a few seconds, they already took the newspaper and read the news articles. So they trusted already the machine, which was great.”

Huhnke’s group then pushed its luck: “We also initialized some emergency situations: ‘So please, go back to your steering wheel and take over, we need some help from you,’ and they did it. They put the newspaper back, and just controlled the car through the situation. Then what did they do? Immediately press the button and start it again — it was really amazing.”

The question, of course, from a human factors point of view, is how quickly the car can alert drivers to a particular emergency (and what the warning will be; either a vague “emergency” or the exact diagnosis), and how quickly they can respond (and whether it’s the correct response) after they’ve been “out of the loop.” Would a texting driver with eyes and mind off-road be able to respond to a path intrusion warning that comes just as the car detects it?

Road Links

I’ve been traveling a lot the last week (currently doing the “milk run” to Australia), hence the lack of updates here, but here’s a few of the myriad things that have come across the transom (apart from those I’ve posted on Twitter):

A reminder of my own piece on Slate about London Transport posters.

London bike hire scheme data visualizations.

A “safer” way to text and drive (as a thought exercise try replacing the word “texting” with drinking as you listen to this).

Endlessly hypnotic: Bicycle rush hour in Copenhagen.

Excellent bike-related stencil art from Adelaide-based Peter Drews.

Adam Greenfield ponders the complexity of bus networks. (“You know I believe that cities are connection machines, networks of potential subject to Metcalfe’s law. What this means in the abstract is that the total value of an urban network rises as the square of the number of nodes connected to it. What this means in human terms is that a situation in which people are too intimidated to ride the bus (or walk down the street, or leave the apartment) is a sorrow compounded. Again: everything they could offer the network that is the city is lost. And everything we take for granted about the possibilities and promise of great urban places is foreclosed to them.)

New standards dictate 3.5 FPS average pedestrian walking speeds.

Forget trashing hotel rooms — today’s indie rockers spend their time twittering about parking tickets!

Recalls media friendly but distort true road safety picture, via the WSJ.

The Chinese used car market.

How about an “ignition interlock” for habitual speeders in Australia?

The always good Carl Bialik on “traffic math.” (and I liked this bit: Nicholas Taylor, a research fellow at the consulting company Transport Research Laboratory in Wokingham, England, says that adding road capacity can be effective if it isn’t perceived as adding capacity. Opening a highway’s shoulder to traffic during peak hours appears to work, Mr. Taylor says, because it is “not seen as a whole new provision of the road. There’s a psychological element to it.”)

Driver distracted by sex toy.

Driver who thought (fatally) he was piloting the Star Trek enterprise ruled “insane.”

The Permanent Jam

A number of people have written in, or tweeted (and don’t forget to find me in the tweetosphere), to tell me about a traffic jam in China, currently in its ninth day, that seems to be on the verge of evolving, as per Cortazar’s story “The Southern Thruway” (an inspiration for Godard’s Weekend), into some kind of makeshift settlement.

This has struck an enterprising verve in some locals, notes the BBC:

The drivers have complained that locals are over-charging them for food and drink while they are stuck.

Then again, what is the “market price” for selling food and drink to 100 km traffic jams?

‘Parking lots are also surprisingly civic…’

Notes Witold Rybczynski, in an interesting slideshow of “ordinary places”:

Parking lots are also surprisingly civic. People politely observe rules of behavior for the sake of the common good, parking between the lines, staying out of the handicapped spaces, driving slowly. It is one place where cars and pedestrians happily coexist.

I’m not sure how happy that coexistence is (e.g., “bad parking”). To wit, this piece from the Washington Post:

[Montgomery County] Employees calculated the numbers and were surprised by the frequency of parking lot accidents. Of the 1,496 pedestrians struck between January 2006 and June 2009, 324 had been hit in parking lots.

Isles of Safety

I have a short essay (accompanied by some excellent images) on the “traffic island” — that curious embankment of legally murky space carved from urban traffic channels, on which all manner of species dwell, from certain varieties of ants to political agitators, — in the current islands-themed issue of Cabinet. It’s not available online, but Cabinet is one of those journals you really want to hold in your hand, not your iPad.

“Where are we exactly — are we near the island?”
‘The “island” — is that what you call it?
“The traffic island. The patch of waste ground below the motorway. Are we near there?”

The Things In Between

I was struck by this random footnote in Mary Roach’s delightful new book, Packing for Mars.

“The April 1995 issue of the Journal of Trauma includes a case report of a man whose pipe was between his BMW’s airbag and his face when the bag deployed. A piece of the stem shot into his eye, resulting in a “ruptured globe.” The author, a Swiss physician, has a keen globe for detail, noting that “there was tobacco all over the floor” and that the injury was similar to those seen “after the thrust of a pointed cow horn.” The paper concludes with an exhortation to “behave appropriately” — no “drinking from cups … holding articles on the lap, or wearing spectacles while driving.” Not to thrust too pointed a cow horn, but wearing one’s eyeglasses while driving surely prevents more injuries than it causes.”

What’s the Most Dangerous Thing About Being a Cop? Traffic

Via Sheriff magazine:

The death of law enforcement officers (LEOs) in motor vehicle crashes have increased by 48% in the past 28 years. Between the years 2005 to 2007, 54% of all LEO deaths “in the line of duty” were motor vehicle crash involved. When comparing the fatality rate of LEOs to the general population, during the years from 1996 to 1999 LEOs deaths by motor vehicle crashes were at the same or lower rate than the general population. Since the year 2000 the fatality rate for the general population has steadily declined, but the LEO fatality rate has been increasing.

Behavioral Economics and Travel

Mark Solof surveys the nascent intersection of these fields at InTransition magazine.

Much of drivers’ overconfidence stems from an “illusion of control” Ariely said. “When we control something, we feel the risk is lower, even when it is not, and this is especially strong in driving.”

On That New Japanese Pedal Design

A number of people have written in to tell me about the new pedal design in the New York Times (as an aside, I always chuckle a bit when I get NYT links, as I have essentially read the paper seven days a week cover to cover since the late 1980s, when a college professor haughtily advised me it “would make a better person” — but I digress). One even reminded me that I was “harsh” on driver behavior (e.g., in this post).

What I had raised objections to in the whole debate over unintentional acceleration was its actual importance in the overall traffic safety picture; and whether our innovative energies wouldn’t be better focused on things like better impaired driving interventions.

That said, as someone who has written quite a bit on design, I’m always in favor of design that makes everyday life better, or eliminates simple human errors all of us, on one occasion or another, are bound to make. We can chastise the “idiots” who leave their card behind in an ATM, or designers can install a simple intervention, the beep that won’t stop sounding until you’ve removed your card. Of course, there are social issues here as well: Given the older demographic that seemed to be particularly implicated in the unintentional acceleration cases, is it a question of improving the car’s design to accommodate older drivers (in essence making a “Jitterbug” version of the car), or of more closely monitoring and perhaps restricting older drivers?

The bigger issue here, as the article notes, is changing the ingrained mass muscle memory of hundreds of millions of worldwide drivers; i.e., would the shift to a new pedal actually cause more injuries than reducing the (rare) instances of accidental acceleration. After all, the new pedal is just one of a number of design tweaks that have been proposed to improve traffic safety (e.g., changing the colors of brake lights or having them give a special display when they are fully depressed), but as the CHIMSIL showed, it takes years of research and testing to actually get these things implemented — and even then the predicted safety benefits might not meet expectations.

Curious to hear what you human factors folks have to say.

B.R.T. (Bus Rapid Tunnel?) in China

Like a giant urban hovercraft sucking up traffic in its wake.

Notes dvice.com:

Do you hate waiting behind a bus as it loads and unloads? Well, friend, does China have the craziest solution for you! A Chinese company is looking to build buses so big cars can drive right under them, which will ease congestion. The company is serious about it, too.

Being developed by the Shenzhen Huashi Future Car-Parking Equipment company, the buses are currently planned for Beijing’s Mentougou district, where tracks on the road will make sure they stay straight as cars drive under them — and they drive over cars. Passengers get on and off at elevated stations, as the bus/trolley/what-have-you are so tall.

Interesting, but left unanswered is the question of how to keep cars in their lane.

(thanks Matt)

More on Carless in Hollywood

The comments section on Slate yields a number of further examples, including this one:

As long as you’re talking about movies that denigrate bicyclists, you should mention the ’90′s film “In and Out” in which Kevin Kline plays a guy who everyone knows is gay except himself. It’s generally quite a funny and genial movie, but they do make a point of showing him as the only bicyclist in town, which seems a way of saying that his bicycling is yet one more piece of evidence (like his love of Bette Midler and somewhat flamboyant hand gestures) that “proves” he really is gay. Even though he appears to live in a small town where bicycling would be a perfectly reasonable way of getting around.
