Rage Against Your Machine

Back in November, I did an unusual bike commute with a guy named Joe Simonetti: I traveled from Northern Westchester County, to Joe’s office in midtown Manhattan (I then continued home to Brooklyn), via a carefully chosen, if not always evident, path that wound through bucolic gated communities in Greenwich, Ct., underneath the concrete underpasses of the city’s edges, to the delivery-truck laden warrens of the Bronx. I was admittedly intrigued by the unusual nature of the commute itself (for me, it was around 65 miles, one way) — in articulating a kind of “secret” way to get into the city it evoked, for me, John Cheever’s short story The Swimmer, whose narrator undertakes a quixotic journey to swim across his suburban county:

His life was not confining and the delight he took in this observation could not be explained by its suggestion of escape. He seemed to see, with a cartographer’s eye, that string of swimming pools, that quasi-subterranean stream that curved across the county. He had made a discovery, a contribution to modern geography; he would name the stream Lucinda after his wife. He was not a practical joker nor was he a fool but he was determinedly original and had a vague and modest idea of himself as a legendary figure. The day was beautiful and it seemed to him that a long swim might enlarge and celebrate its beauty.

But I also wanted the journey to serve as a kind of Ur-text for exploring the state of riding a bike in America today, to examine the mechanisms of the oft-cited “culture war” between drivers and cyclists. In any case, the story, headlined ‘Rage Against Your Machine,’ is out today, in the new issue of Outside magazine. As far as I know it’s not online yet (I imagine it will be eventually), but I would, of course, urge you to buy this or any other issue of Outside in print. In the meantime, a few handlebar shots of the sometimes beautiful, sometimes foreboding landscapes we traversed.

Rear-entry Parking Revisited

Thanks to the voluminous response from blog readers that I received in light of the earlier query on this blog, I’ve expanded the thoughts on rear-in parking into my latest Slate column, in case you haven’t seen it.

Arteries

Lisbon’s blood vessels from Pedro M Cruz on Vimeo.

Via Pedro Cruz:

In this work the traffic of Lisbon is portrayed exploring metaphors of living organisms with circulatory problems. Rather than being an aesthetic essay or a set of decorative artifacts, my approach focuses on synthesizing and conveying meaning through data portrayal. This portrayal is embodied in the visualization: The Blood Vessels in the traffic of Lisbon. I use an adaptive physics system to build and manipulate the road network – the thickness, the color and the length of the vessels are excited by the number of vehicles and average velocity in each road. With this system I try to bypass the strictness of contemporary visualizations that depict data accurately through direct mappings.

The Rise and Fall of the American Paperboy

I have a short essay in the next issue of Time magazine (it will be online a week later) looking at the historical career of the American paperboy. Due to the vicissitudes of publishing, the piece had to be rather severely cut, but here is the longer, original version.

* * *

Walking downstairs the other morning to retrieve the newspaper, I realized I was the last person in my Brooklyn apartment receiving the daily New York Times and Wall Street Journal. The number swells a bit on weekends, but Monday through Friday find me alone in my ritual.

Trudging back through the snow, thinking about the future of this physical object and its delivery, I suddenly wondered: Were there any paperboys left in America? Certainly not on my block: The Times shifted to all-adult carriers over a decade ago. Mine wasn’t the image of Norman Rockwell and Leave it to Beaver — a boy on a bike — but a guy in a van from Staten Island. But did this once familiar cultural icon still exist? Where had he gone? And why should we care?

The paperboy has been subject to two distinct forces. The first is the newspaper business: Not just circulation — which peaked in 2000 and has been dropping since — but when papers were delivered. 2000 marked the first time there were more morning than evening papers. This helped accelerate a shift begun a decade previously, when from 1980 to 1990, the number of adult carriers had risen by 112 percent, while youth carriers had dropped by 60. Most children either could not or were not willing to get up and deliver papers by 6 a.m.

Cost-conscious newspapers shifted to large “distribution centers,” meaning carriers needed to distribute bigger bundles of papers across a wider area — via car. To entice adults, newspapers changed the name: The “paperboy” became an “independent delivery contractor.” They changed the job: Few carriers today do collections. And they changed the delivery experience: In what’s referred to as the “controversial tube-vs.-porch delivery dilemma,” instead of a kid putting it on your porch (or in the bushes), an adult in a car would put it in your roadside mailbox.

The larger culture around the paperboy also changed. Kids stopped delivering papers for the same reason they stopped walking to school — since the early 1970s the percentage has from over 50% to just 11%. Stranger danger, for one. In a high-profile case in 1982, a 12-year-old Iowa boy named Johnny Gosch disappeared while on his paper route in West Des Moines. But as Free Range Kids author Lenore Skenazy notes, stranger abductions haven’t been rising, and violent crime involving children has been dropping (lest you think it’s because we stopped letting children be paperboys, she notes all violent crime rates have dropped). “If we only focus on the rare and horrible,” she says, “we will be too scared to let our kids do anything.”

People also began moving to exurban regions that were simply too spread out for kids on foot or on Scwhinn Stingrays, where streets were deemed unsafe for anything but the inside of a car (even if that’s where most accidental injury occurs to children, as Skenazy notes). From 1981 to 1997 youth participation in organized sports doubled; where nearly half of 16 year-olds had a summer job in 1978, just above 20% did by 2008.

But so what? Why should we lament the passing of an entry-level, low-skilled job? Do jobs for kids actually do any good? Interestingly, Bureau of Labor Statistics research shows that men who worked in high school earned more than a dollar more on average at age 27 than those who did not. Was it the job, or were those kids simply more motivated? History teases suggestively: Benjamin Franklin delivered The Boston Gazette, Thomas Edison sold papers at the age of 12, and Warren Buffet, long before he was trying to buy the Washington Post, was delivering it.

Ask a former paperboy about the job and you’re likely to summon a misty-eyed recollection of predawn bundling and knee-high snow. “Today it’s basically something that doesn’t exist,” said Today host Matt Lauer. “It’s a bit of innocence lost — and it meant a lot to me as a kid.” Clarence Eckerson, a filmmaker (and former paperboy), describes it as “an amazing responsibility to have as a teenager, to essentially be a private business, collecting money and paying a weekly bill.”

After these ruminations, I was admittedly pleased to find that there are still paperboys — and girls — in America (even if, in 2008, they made up only 13.2% of all carriers, down from nearly 70% in 1990). As Fred Masenheimer, publisher of The Times News, a newspaper with roughly 14,000 subscribers (“in central eastern Pennsylvania, just north of Allentown”) told me, the daily paper not only employs an all-youth carrier force — it’s resisted shifting to morning distribution precisely so it could keep those carriers.

“I think it’s a vital part of a kid’s growing up and learning to be their own business person,” say Masenheimer. About half of the paper’s 100-plus carriers deliver papers alone, while the rest have parental supervision — particularly younger children. This is partially for safety, partly to ensure delivery. “When you put your reputation o the back of a 10 or 12 year old kid, you want to make sure that they’re doing the job properly,” he says. In 41 years of publishing the paper, he’s seen countless carriers go on to college, or routes change hands several times within the same family.

Those carriers still risk the occasional dog bite, and they still sling canvas bags across the handlebars of their bikes. Masenheimer himself was a paperboy, delivering The Hanover Evening News. “They used to tell us it was the last two-cent newspaper in America,” he says. “So you can imagine how much money we made in a week.” Nobody’s getting rich as a carrier, he concedes, “but nobody’s getting rich as a journalist these days either.”

A Response to Hainline, Steisel, and Weinshall

I am glad that my posting on the Prospect Park West bike lanes occasioned a serious and thoughtful response (see the comments).

I wanted to reply to a few points.

They write:

(1) PPW is not simply an arterial roadway between intersecting streets (as is the adjacent roadway inside Prospect Park, which, we have argued, would be a more appropriate location for a two-way bike lane). Rather, PPW borders high-density residential blocks—with a school and elder-care facility (on one side of the street) and entrances to Prospect Park (on the other). This means that on a less-than-one-mile stretch of roadway, thousands of residents and park-goers are continuously entering or exiting school buses, wheel-chair vans, taxis, or driveways, while dozens of Fresh Direct, UPS, Fedex, USPS trucks, moving vans, and other delivery vehicles are also blocking one of the two remaining traffic lanes. This requires that drivers in the blocked lane continuously shift into a single more-heavily-used traffic lane to avoid the blockage. And since this single lane is now narrower on a significant stretch of PPW, if not the entire street (as our measurements, pace Vanderbilt’s assertion to the contrary, clearly show), there is less margin to avoid car doors opening, drivers or passengers squeezing into their vehicles, parents lifting babies from their car-seats, cars edging into or out of parking spots, or side view mirrors extending from vehicles. These circumstances, rather than producing a “calming feeling,” are more likely to produce irritated impatience, at best.

I admit that the studies I referred to are for road types different from PPW; in part this is a necessity because of the rather unique nature of PPW itself. But I am interested here in their description of all the exiting school buses, UPS trucks, parents getting babies out of cars, Fresh Direct vans, etc. Given this huge amount of stopped traffic, and pedestrian activity, to my mind the most important safety benefit we could bring to those users is a reduction of the speeds on that street — which were typically well above the speed limit prior to the installation of the bike lane. Speed, and the violating of right of way — not lane changing and merging — is the root cause of the vast majority of serious traffic injury in New York City. As I’ve said repeatedly, drivers, in their ‘irritated impatience,’ have tended to use PPW as a high speed arterial to neighborhoods beyond Park Slope rather than the neighborhood street it should be. I will take an infinite number of bent mirrors over the lives or health of any one person.

In their second point, they note:

“In addition to the option of moving the lane onto the adjacent roadway inside the park, making the PPW bike-lane one-way is the other proposal we have made as members of “Neighbors for Better Bike Lanes.”

I would take a one-way bike lane over no bike lane; but as a condition of that one-way status, I would call for a protected one-way bike lane, in the other direction, on Eighth Avenue, which suffers from some of the same speed problems as PPW.

They then note:

(1) Vanderbilt’s basic argument relies on the perception of increased safety that roadway users (drivers, bikers, and pedestrians) may have when more drivers and riders are using fewer and narrower lanes, because their awareness of other roadway users is heightened. But this perception of increased safety is not what users of PPW have experienced. In a self-selected survey of over 3,000 Brooklynites conducted by Councilmembers Lander and Levin, most people—bikers were the only exception—reported feeling less safe after the bike lane was installed (Ref. 2).

This misrepresents what I have said, and indeed highlights a problem: Perception of safety and actual safety in traffic are not always the same. When subjects have been asked to identify what they think are crash hot spots in certain locations, for example, they often choose places with low numbers of crashes, not the actual hot spots. When roundabouts are installed, it’s quite common for the local populace to protest that their safety has been compromised — when in fact, roundabouts, as have been documented in any number of studies, tend to make things safer for all road users. ‘Shared space’ experiments in Europe and the U.K. have shown a similar disconnect between perceived and actual safety.

But let’s stick to what we know: The actual numbers from PPW, which are now available, via the Brooklyn Paper:

“Crashes are down from an average of 30 in six months to 25, or 16 percent.

• Crashes that cause injuries are down from 5.3 in six months to two, a whopping 63-percent drop.

• Before the project, a crash was twice as likely to include an injury.

• Injuries to all street users dropped 21 percent.

The data also found that since the lane was installed last June, there have been no reported pedestrian injuries and no pedestrian or cyclist injuries from pedestrian-bike crashes.”

Granted, crashes involving pedestrians and bicycles tend to be underreported, but vehicle crashes, particularly involving injury, are not — and by this measure, the addition of the lanes has actually made for a safer environment for all road users. An increase in active transportation; a decrease in injury — I fail to see this as a problem.

A Question of Parking

Reader Jeff poses this query, which I admit has puzzled me as well (but to which I have no convincing answer):

“What makes some people back into parking spaces’ [in parking lots] rather than pull straight in? Is this a regional thing (in the south)? I’ve always thought that it takes much longer to back into the space and pull straight out than it takes to pull straight in and back out of the space.”

Is it some Starsky and Hutch move for maximum preparedness, to be able to whisk out at a moment’s notice? Is it something they teach security professionals in evasive driving techniques? As Jeff notes, either way you’re backing up, so there’s no overall time saved. Anyone have an idea?

[P.S. As usual, great responses here; and I'm wondering if we're on to some deep, if absolutely unscientific, personality indicator here — are you a nose-in or tail-in parker?]

Painted Roundabout

From somewhere in Germany, I believe (would be curious to know the exact location), a roundabout with nothing in the center save paint. I’d be curious about the stats for this intersection; on the whole it seems more or less orderly (there’s confusion but low-speed confusion), but some people just seem to blow straight through as if they had a green light in a signalized intersection.

Desire Named Streetcar

My latest Slate column looks at two transportation forms, the monorail and the streetcar, each with their supporters and each with their detractors, and how time’s arrow seems to have inverted somewhere along the way:

What’s interesting about Disney World and Disneyland is not merely the range of transportation options, but the mixture of new and old modes they represent. These varied ways to get around reflect biographer Neal Gabler’s observation that Walt Disney was “at once a nostalgist and a futurist, a conservative and visionary.” One imagines he would have been equally happy riding the retro trolley on Main Street as whisking through Tomorrowland in an ultramodern monorail.

But there is something else to note here. The monorail—which must have looked to Disney and the world like the transportation of the future in the 1950s—is now, to many, considered a historical footnote, a relic of World Expos or, at best, an automated ride between airport terminals. America’s highest-profile monorail project, the expansion of Seattle’s line, was plagued by cost overruns and funding gaps, and was finally dissolved in 2005 (costing taxpayers $125 million). The Las Vegas monorail has filed for bankruptcy. At the same time, those retro streetcars, which Disney himself rode in Kansas City in the early 20th century and which must have seemed to him part of a vanishing past, are returning (or may soon return) to any number of American cities, including Washington, D.C.; Cincinnati’ Tucson; Atlanta; Dallas; St. Louis; and Salt Lake City.

So the future we thought we were going to get somehow seems antiquated, while the past looks increasingly, well, futuristic. Why is the trolley ascendant as the monorail declines?

[P.S. I do realize a fair number of people prefer buses to either of these options, but for space it was cut. An original line read: "Light-rail supporters — and transportation people, whether for reasons of funding, fandom, or something else, and even if they’re working toward similar goals, tend to cleave into camps (a third group, the bus people, find their vessel of choice superior to both the light-rail and monorails) — counter with a battery of well-practiced rejoinders..."]

Stranger than Fiction

I was intrigued by this passage from a typically fascinating Paris Review interview, this time with science-fiction legend Ray Bradbury:

If I’d lived in the late eighteen hundreds I might have written a story predicting that strange vehicles would soon move across the landscape of the United States and would kill 2,000,000 people in a period of seventy years. Science fiction is not just the art of the possible, but of the obvious. Once the automobile appeared you could have predicted it would destroy as many people as it did.

No Signal

Joburg thieves steal SIM cards from traffic signals.

Makubela said the agency was now cancelling the SIMs stolen from the GPRS units inside some of the traffic lights and working with Johannesburg police to stop the traffic light thefts. Ordinary lights have not been targeted by the gangs – although there were some thefts of traffic light poles last year for their scrap value.

In Constant Peril

Reading Bill Bryson’s At Home, a big, genial shaggy dog of a book brimming with turn-to-the-wife-did-you-know-that moments (in other words, absolutely recommended), I came across this interesting traffic note, about the blackouts introduced to Britain at the outbreak of the war:

Drivers had to drive around in almost perfect invisibility—even dashboard lights were not allowed— so they had to guess not only where the road was but at what speed they were moving.

Not since the Middle Ages had Britain been so dark, and the consequences were noisy and profound. To avoid striking the curb or anything parked along it, cars took to straddling the middle white lines, which was fine until they encountered another vehicle doing likewise from the opposite direction. Pedestrians found themselves in constant peril as every sidewalk became an obstacle course of unseen lampposts, trees, and street furniture. Trams, known with respect as the ’silent peril,’ were especially unnerving. ‘During the first four months of the war,’ Juliet Gardiner relates in Wartime, ‘a total of 4,133 people were killed on Britain’s roads’—a 100 percent increase over the year before. Nearly three-quarters of the victims were pedestrians. Without dropping a single bomb, the Lutwaffe was already killing six hundred people a month, as the British Medical Journal drily observed.

Ramps to Nowhere

Flickr/Jason McHuff

My latest Slate column looks at a number of urban highway projects that were once planned but never built (or were built and then torn down). Here’s the gist:

A new exhibit at New York’s Cooper Union, Paul Rudolph: The Lower Manhattan Expressway—complete with an exhaustively recreated large-scale model of the proposed road—provides an opportunity to consider the invisible (and sometimes visible) presence of this and other phantom highways in the world’s cities. Existing merely as segments of many-tentacled schemes on faded planner’s maps, they are more than historical oddities or visions of an alternate future. They’re part of an ongoing dialogue about the meaning and possibilities of mobility in the world’s cities: Would their host cities be better off if these highways been built? How should we balance the desire for mobility with the desire to create livable, meaningful urban spaces? Is there any room for the megaprojects of Rudolph in a city that now favors pocket parks and restriped bike lanes?

There were plenty of examples I had to leave on the cutting-room floor, everything from Portland’s Mt. Hood freeway (the stub is pictured above) to the wider network proposed by Pompidou in Paris to Milwaukee’s Park East Spur, and if anyone has any images, recollections, would be curious to hear.

And now, if you’ll excuse me, I’ve got some Yule matters to attend to…

On Bike Lanes, Road Widths, and Traffic Safety

There was an assertion made in one of the letters (signed by Louise Hainline, Norman Steisel, and Iris Weinshall in response to a recent New York Times editorial on cycling that caught my eye:

When new bike lanes force the same volume of cars and trucks into fewer and narrower traffic lanes, the potential for accidents between cars, trucks and pedestrians goes up rather than down. At Prospect Park West in Brooklyn, for instance, where a two-way bike lane was put in last summer, our eyewitness reports show collisions of one sort or another to be on pace to be triple the former annual rates.

The first point is that while the PPW conversion did take away one travel lane, the width of the existing lanes was not altered. So there may be fewer lanes, but they are not, as the letter argues, “narrower.” It may be that entire street feels narrower, which, as an emerging school of what I’ll call ‘behavioral traffic calming’ argues, is actually a good thing. Drivers, as I’ve quoted Ezra Hauer as saying, “adapt to the road they see.” They either do not see traffic signs or fail to read their meaning correctly. If they see a wide open, long boulevard, they will drive like this.

Even if the lanes were narrowed, as John LaPlante recently argued in the journal of the Institute for Transportation Engineers, “there is no significant crash difference between 10-, 11-, and 12-foot lanes on urban arterials where the speed limit is 45 mph (or less).” (a finding, he notes, that was unfortunately left out of AASHTO’s recent Highway Safety Manual).

And there’s something deeply suspicious about that “eyewitness reports” note; were they actually out there, day after day, meticulously logging conflicts and crashes (tellingly, they make no note of severity)? And why, if everything was so great with the street before, were they even doing these “before” counts? As the case of roundabouts shows, what people perceive as individual danger often does not translate at all to an increase in overall risk; in fact, it’s quite the opposite.

But let’s take that notion — that fewer and narrower lanes lead to more crashes. This is a staple of traffic engineering, and in fact it does have some validity — when applied to highway environments (which PPW at times unintentionally resembles). Even here, though, the effects are often not ’statistically significant’ and ‘more complex than expected.’

But in non-highway environments, there’s all kind of evidence that reducing the number of lanes (a.k.a. the ‘road diet’) can have positive safety benefits. As the Federal Highway Administration has noted:

Road­ diets­ can­ offer­ benefits ­to­ both ­drivers ­and­ pedestrians… road diets may reduce vehicles speeds and vehicle interactions, which could potentially reduce the number and severity of vehicle-to-vehicle crashes. Road diets can also help pedestrians by creating fewer lanes of traffic to cross and by reducing vehicle speeds. A 2001 study found a reduction in pedestrian crashing risk when crossing two-and three-lane roads compared to roads with four or more lanes.

But what if one of those lanes your crossing is a bike lane? Surely that must make things less safe, no? More interactions in less space. In a forthcoming paper to be published in the Journal of Environmental Practice Norman Garrick and Wesley Marshall examined 24 California cities (12 with relatively low traffic fatality rates, 12 with relatively high rates). They found that the cities that had a higher bicycle usage had a better safety rate, not just for cyclists but all road users. They write:

Our results consistently show that, in terms of street network design, high intersection density appears to be related to much lower crash severities. Our street design data also contains strong indications of these trends; for example, the high biking cities tend to have more bike lanes, fewer traffic lanes, and more on-street parking. At the same time, large numbers of bicycle users might also help shift the overall dynamics of the street environment – perhaps by lowering vehicle speeds but also by increasing driver awareness – toward a safer and more sustainable transportation system for all road users.

And as Eric Dumbaugh, of the University of Texas A&M, notes, “most recent research reports that wider lanes on urban streets have little or no safety benefit, at least to the extent that safety is measured in terms of empirical observations of crash incidence” (e.g., Potts, I.B., Harwood, D.F., & Richard, K.R. (2007). Relationship of Lane Width to Safety for Urban and Suburban Arterials. Transportation Research Board 2007 Annual Meeting; Milton, J., & Mannering, F. (1998). The relationship among highway geometries, traffic-related elements and motor-vehicle accident frequencies. Transportation 25, 395–413; and so on).

But the authors of this letter are not trafficking in empirical evidence, even as they allege that the NYC DOT’s data “more puzzlement than enlightenment.” It’s unfortunate that this letter is signed by a former DOT commissioner, and an academic — who should both know that it is evidence and analysis, not vague “eyewitness” reports and random testimony, upon which good science, planning, and safety interventions are made.

And as always, curious to hear of more work either supporting or countering what I’ve said here.

Fewer Sidewalks, More Pedestrians

As I’m sure most of you know, Google’s NGram Book Viewer provides an invaluable window, via written texts of the last century or so, onto what the culture was collectively thinking. Not surprisingly, there’s much to be gleaned here from an urban or transportation point of view.

Exhibit A is the first word: Pedestrian.

You see that this word, never that popular, essentially held flat, prior to the automobile, when it began to rise. There was a drop-off after World War II, perhaps in response to postwar suburbanization — people were doing less walking. But then it continues to grow year after year, to the present — even as Americans were walking less every year. This is curious on the one hand, but predictable on the other. As people did more driving, and less walking, the notion of what was once a rather common, everyday activity — walking — became a more specialized “mode of transportation,” something to be considered as The Other, something even, dare I say, a bit strange.

For a sense of what was going on as pedestrian became a more common word, let’s turn to Exhibit B: Jaywalking.

Even as fewer people were walking, there was an increased prevalence of the term jaywalking. This reflects the idea, as noted in Peter Norton’s book Fighting Traffic, which I’ve discussed here often, that people on foot — now “pedestrians” — bore a greater responsibility for their own safety (where the burden had once been on drivers); not to mention that they were considered an obstruction to the smooth flow of vehicular traffic and thus worthy of demonization.

Maybe people were jaywalking more because as, Exhibit C hints at, there were fewer sidewalks in America (that little uplift at the end, however, is an encouraging sign).

And, just for fun, Exhibit D shows another form of built space that was on the rise: Driveways. These are found even in places that don’t have sidewalks.

I’ve been posting other results via Twitter, but would be curious to see your “UrbaNgrams.”

You Might be a Transpo Geek If…

Speaking with a friend the other day, I used some word or another, then said, in response to his puzzled look, ‘oh, sorry, that’s a transpo geek word.’ He then asked what a constituted a transpo geek. And so, in the spirit of Jeff Foxworthy, here’s a list of things that just might flag you as a transpo geek (and your further suggestions are more than welcome):

1. You’ve corrected someone in the past year that ‘it’s not a yellow light, it’s an amber phase.’

2. You use the word mode in relation to anything but pie with ice cream.

3. You honeymooned in Curitiba.

4. You proposed on the Disney Monorail.

5. You have ready familiarity with all of the following acronyms: HSR, PRT, VMT, MAX, HOT, MUP, VRU.

6. You have trouble talking about roads or lanes or sidewalks without resorting to the word ‘facility’; e.g, when you hear the Beatles’ song, it’s all you can do to not sing ‘the long and winding facility …’

7. You’ve installed a tube counter in your own driveway.

8. You’ve installed Bott’s dots in the middle of your two-car driveway.

9. When someone mentions “ice tea,” you’re not thinking about a cold drink.

10. You’ve made it this far along in the list.

Any others?

The Car As Renter of the City, Not Landlord

I have a short piece in the current World Policy Journal in response to the question of the future of the city. In this telegraphic dispatch I addressed the place of the car in the city (N.B.: The piece could also be headlined: ‘An Open Letter to Marty Markowitz’):

We spent much of the twentieth century engaged in a campaign to retrofit our cities to the car. However much this may have seemed to make sense at the time, it now looks more like a misdirected effort to save the city by destroying it. As plentiful as the benefits of individual vehicular mobility may be, the large metropolis can never comfortably accommodate any more than a fraction of its citizens in this manner, and we have learned the consequences of trying to do so. Ever-lengthening commutes have meant degraded public spaces, negative health outcomes, social fragmentation, infrastructure whose maintenance goes underfunded.

In the city of the future, we need to pursue policies that allow for safe, efficient and affordable transport of the many, while recognizing that market-based approaches that so rationally apportion space in the private sector can and should be applied to the valuable urban space — in the form of roads and parking spaces—that cities essentially give away. We need to recognize that streets are public spaces too, and not merely, in the old view of 1930s utopian modernism, channels for moving as many vehicles as quickly as possible. The car will continue to exist, but should be treated as a “renter” of the city, not its landlord. The urban car of the future should be shared, smaller, and slower.

Chris Burden’s Metropolis 2

Here’s some art for you highway geeks, though admittedly, this looks more like the high-tech sorters in an advanced logistics hub than a real road (there’s no way, for example, the cars could maintain that close headway on an uphill incline!)
