Traffic and Algorithms in Seattle

Bill Beaty, the amateur “traffic waves” scientist described in Traffic, writes in to describe his early experiences with Seattle’s new Active Traffic Management System — the “dynamic” system of varying speeds, imported from Europe, which is meant to ameliorate the impact of drivers driving into vast stop-and-go traffic (with the ensuing shockwaves).

Beaty was curious to note that the first part of the project is happening on the very section of I-5 where he first began developing his one-man crusade for traffic harmonization. Here’s how he describes his new commute, which seems to have some of the disequilibrium that new schemes bring:

In the first week it created very strange patterns: huge I-5 jams on
Sunday (when Sunday I-5 northbound has always been empty.) They now seem
to be tweaking their algorithm. Or perhaps drivers are no longer freaking
out. Patterns are still odd, but keep changing over many days.

From what I can see, they’re trying to limit the inflow to the daily
northbound jam at I-5 and I-90 interchange. The result is a large
slowdown far south of the city, with an empty region right at the location
of the daily jam. Very odd to encounter a major slowdown near my own home,
where there never was congestion before …but then at the usual location
of the giant I-5 snarl, the traffic flows free at 50mph. Presumably there
no longer exists any continuously-growing daily jam. Merging at city
exits has suddenly become easy. Probably the old jam has been converted
into shockwaves moving slowly backwards, rather than the previously huge
region of 20mph driving.

Another ATMS section is on I-520 …which is right where I first saw the
string of headlights that inspired my first online article. Bizarre
coincidences. Or maybe the bigwigs in the Seattle traffic control
community have all been reading my site? :)

Any other Seattle-area readers/engineers care to share their experience?

When SatNavs Attack

My latest Slate column is up, and it considers the emerging legal questions about liability in cases of crashes in which faulty GPS information is implicated.

And yet what happens when the world that is depicted is different from, or has not yet caught up to, the external world, and something goes awry? Where does the fault lie? Drivers, one might argue, should never rely entirely on a map—what family vacation hasn’t had its moments of (nonlitigable) high drama, with parents squabbling over a desert shortcut promised by Rand McNally that was washed out in the spring runoff? But there is a difference between glancing at a map for initial guidance (and then relying on signs or the road itself for information) and the new way of navigating, which is to receive authoritative real-time spoken and visual instructions—at a level of granularity measured in meters or feet—as one actually drives.

Speed Eraser

You have to love the irony.

Up went the Gatsometers, the Dutch brand that dominates the speed camera industry. Named after founder Maurice Gatsonides, a famous race car driver who developed the first speed monitoring system more than 50 years ago to help himself improve his speeds around corners, the early Gatsometers were rudimentary — cars ran over a wire, triggering a stopwatch that shut off after a second wire was tripped.

From a reasonably measured piece in the Washington Post.

More on Gatsometers at Slate.

iTransport

My latest Slate column considers transportation from an iPhone-centric point of view, with an eye toward ways apps might change the experience for the better. I’d be curious to hear what I left out (I omitted some things for space) or things that are in the works, or apps you’d like to see, etc.

Emotionally Intelligent Bollards

One of the most universal, and seemingly intractable, problems in the world of traffic is controlling drivers’ speeds on local streets, particularly those with children present. The latest approach, in Leicester, England, combines hardcore traffic engineering — steel bollards — with a more humanistic side: They literally look like small children standing on the side of the road.

There is, admittedly, a bit of a Village of the Damned look to the bollards — and yet also something rather cheerful, something like foosball players — but perhaps, echoing Daniel Pink’s “emotionally intelligent signage” proposal, they may trigger some instinctual response, reminding drivers of the presence of humans (and, after all, studies have shown that images of humans, particularly human eyes, can be as persuasive as real humans).

Not surprisingly, the locals are a bit divided.

Sylvia Thomas, who lives in nearby Greenhill Road, said: “I can’t see the point of them. If they are there to calm traffic they don’t work, because one has already been knocked over.

“They are quite strange.”

Helen Evans, 44, from Knighton, said: “They look great. I think they’re cute – and hopefully they will make people drive more carefully and remember there are children around here.”

As to the first commenter, rather than viewing it a failed solution, the idea that one has already been knocked down might simply demonstrate the extent of the problem. And the bollards are merely one part of a wider strategy, including striping and a new 20 mph speed limit.

From another story came this comment:

The RAC told Sky News Online that there was a risk “the statues will become a distraction with drivers focusing on them rather than the road ahead.”

One way to deal with that issue would be to put a few in the road. But of course there’s also the issue that real pedestrians will become a distraction — do we ban them from roadsides? Do we strip any sign of life from city streets so drivers will not have their precious roads obscured, their perilous attention (probably already compromised by their phone) fractured any further?

In any case, I’ll be curious to hear of any before/after speed comparisons.

Silent Majority on Red-Light Cameras?

Via online only Seattle Pi.com comes an interesting tale of tentative success with red-light cameras.

This bit stood out:

A random telephone survey of 400 people last August showed an 85 percent approval rate, Quinn said. And city officials continue to get unsolicited recommendations for intersections to install new cameras.

I don’t know the specifics of that survey, but given that nary a day goes by that I don’t hear the old charges about cameras “increasing accidents” — without identifying the much more serious crashes that same cameras have reduced — and being simple revenue-raising tools for municipalities, I was surprised by the high level of seeming support.

Or maybe it’s a Seattle thing (I once received a jaywalking warning there by an officer in blue).

Red Yellow Green

In Traffic I make a passing mention of the evolution of traffic light sequences:

Others wanted the yellow light shown before the signal was changing to red and before it was changing from red back to green (which one sees today in Denmark, among other places, but nowhere in North America).

Reader Claire writes in to note that she remembers this sequence being used in the U.S.:

I distinctly remember passing through signals of this type on arterial streets in Chicago between 1977 – 1983. They were mostly located west of the L tracks on arterial streets like Belmont, Armitage, Fullerton, Devon, and Ashland.

Now, I didn’t say they were never used in the U.S., just that they aren’t anymore — although I may be wrong here and I’d be curious to see an example. She helpfully points us to Willis Lamm’s Traffic Signal page, which contains video examples of these “really funky signal phases.”

I’ve seen international studies on the potential problems with the red-amber-green phase, but haven’t really heard or read an account of why these phases vanished in the U.S. (though I’m sure the information is out there, in some back issue of the ITE Journal). I can imagine there are pedestrian issues, not to mention intersection clearance issues. And given that hardly anyone drives a manual shift in the U.S., one of the perceived virtues of that system is now largely lost here, like an old piece of slang no one uses anymore.

When You Truly, Absolutely Need Stop Sign Compliance

Here’s an extreme case of where stop sign compliance is really a life or death situation: U.S. military checkpoints in Iraq and Afghanistan. A fascinating brief in the New Scientist notes that:

When a vehicle approaches a checkpoint at speed, ignoring warning signs to slow down, troops do not know whether the driver is simply careless or a suicide bomber. They need a clear and harmless way of forcing drivers to stop.

Green laser “dazzlers” were created for this purpose, the magazine notes, “but at short range they can damage the eye, and a number of US troops and civilians have ended up in hospital with eye injuries after ‘friendly fire’ incidents.”

But a more benign solution is in the works:

Now the US Department of Defense’s Joint Non-Lethal Weapons Directorate (JNLWD) in Quantico, Virginia is developing a pulsed laser designed to prevent eye damage. Its wavelength means a portion of the light is absorbed by the vehicle windscreen, vaporising the outer layer of the glass and producing a plasma. This absorbs the rest of the pulse and re-emits the energy as a brilliant white light that is dazzling but harmless. Because the light is emitted from the windscreen, the effect on the driver’s eyes should be the same regardless of the vehicle’s distance from the laser.

I don’t suppose this sort of thing would fly on civilian roads; but, for example, as a can’t-miss traffic light, or a way for police to disable drivers in pursuits, or a form of extreme neighborhood traffic calming…

A Passing Fancy

I’m fascinated by all the curious would-be traffic safety devices lingering in dusty patent offices around the world, a collection of better brake lights, more evocative horns, elaborate safety harnesses, etc., that have never made it onto the road (for better or worse).

I came across the one above, recently, via Modern Mechanix. It’s evidently meant as a way to make passing other vehicles on two-lane roads a safer proposition.

But a few problems come to mind:

1.) As with all new signals, there is the problem that many drivers don’t use the existing signals they have.

2.) What if a driver is distracted or doesn’t care to respond to your request for passing clearance?

3.) Are we really to trust the driver ahead to tell us if it’s safe to pass?

4.) Does the driver ahead want to be held liable if it turned out it wasn’t safe to pass?

The Trixi Mirror

The Guardian notes that London, under the guidance of cyclist-mayor (and near traffic fatality) Boris Johnson, is installing a number of so-called “Trixi” mirrors as it ramps up its “cycling superhighways” ahead of 2012.

This is to help ameliorate a quite clear pattern of danger in truck-cyclist interaction:

Of the 15 cyclists who died on the capital’s roads last year, nine were killed in collisions with lorries. In most cases the lorry was turning left and the driver failed to see the cyclist on their inside, according to TfL.

As even the most cautious driver can fall victim to blind spots, this seems theoretically like a good, low-tech idea. I’m wondering if anyone has seen any data, pre-post installation, on whether they actually help reduce incidents? And one wonders whether the burden shouldn’t fall onto the truck itself having better mirrors, as one can imagine the many intersections that wouldn’t be equipped. Also wondering if readers have come across these in other cities?

The curious name, by the way, comes from a German girl, “Beatrix Willburger, who was 13 when she collided on her bike with a cement mixer. Her father then developed a convex mirror to be mounted on traffic lights at intersections. It lets truck and bus drivers see all around their rigs before driving off.”

Warning: Zeignarnik Effect Ahead

Reading Roadguy’s account (I’ve got the Twin Cities on my mind, I guess) of his trip to this year’s American Planning Association meeting, I was intrigued by his description of a panel on “digital billboards.”

Roadguy noted a delicious sort of Catch-22 during the talk: “Fellow panelist Marya Morris, a Chicago-area consultant, pointed out the conundrum that owners of digital signs face: They argue that the signs aren’t distracting while simultaneously telling advertisers that such billboards “can’t be ignored.”

I’ve not yet seen a good, peer-reviewed study on the safety (or lack thereof) of digital billboards (and if anyone has, please advise). Anything from the industry must be viewed as suspect (guess what: they’re safe!), and a controlled, before-and-after study of a highway section where a billboard has been added would be a tricky proposition (unless it became an immediately apparently crash hotspot). One study I’d like to see done, just of out curiosity, would be to gather loop data near the billboards: Do they have a deleterious effect on traffic flow itself?

Roadguy noted something else of interest: “Morris and Baker both spoke about the Zeignarnik effect, a psychological compulsion to focus on a task not yet completed, and how it causes drivers to look at digital signs repeatedly. Baker cited a billboard in Cedar Rapids, Iowa, as particularly perilous: it displays multi-part riddles.”

Not having had any psychology as an undergrad, this Zeigarnik effect was new to me, but as I love a good effect (who doesn’t?), I cast a cursory Google-glance over at 43folders and found this delightful account:

“While sitting in a restaurant in Vienna—every good story about a psychologist takes place in Vienna—Bluma Zeigarnik noticed that a waiter could remember a seemingly endless number of items that had been ordered by his customers. However, once he had delivered the orders to the waiting diners, he no longer remembered what he had just served….

Though Zeigarnik didn’t get her coffee cup refilled following her meal, she did get into the annals of psychology. Zeigarnik theorized that an incomplete task or unfinished business creates “psychic tension” within us. This tension acts as a motivator to drive us toward completing the task or finishing the business. In Gestalt terms, we are motivated to seek “closure…”

The implication is that people remember incomplete processes more more than those that are completed.

I’m no brain expert or psychologist, but I wonder if the waiter was simply storing those orders in short-term memory, and, having concluded they were no longer of importance, was not encoding them to longer-term memory (and just how many orders could a waiter remember, echoes of that “seven-digit” effect of short-term memory).

And I can also imagine this this effect might be served up by marketers as a bit of psychological juju to help sell their product: As opposed to a static billboard, whose message one would instantly absorb and then discard (as with one’s memory of traffic signs they’ve passed), some sort of narrative-in-progress might leave the driver/viewer hungry for a kind of resolution, “wanting more,” and thus dwelling more on the subject than they might have. But again, it’s hard to argue that the same stickiness that’s good for marketing would be good for driving.

The Latest iPhone App: Crosswalk Warning

A new study in Accident Analysis & Prevention by Jack Nasar, Peter Hecht and Richard Wener finds that pedestrians on mobile phones were less aware of their surroundings and crossed streets less safely (curiously, a sample using iPods seemed less distracted, leading the authors to speculate “perhaps listening to music is a different kind of distraction than listening to words”).

The authors wonder if a technological fix might be appropriate. “Perhaps, the mobile phone or i-pod could alert pedestrians they were approaching a crosswalk or that a car is approaching.” This raises new questions. “If so, would the pedestrian notice and heed the warning?”

“Ford Lanes”

Some interesting numbers out of an HOT on Highway 167 in Washington state.

People seemed willing to pay $1 to lower their commute by 10 minutes in heavy congestion.

The highest possible tolls is $9, and only a dozen paid that in heavy-traffic July.

HOT’s have been famously tagged “Lexus Lanes,” but some reports have been shown them being used by a broad variety of users across income, etc., lines. The most common vehicle found in these lanes were not Lexuses (Lexi?) but Fords (7,500 of ‘em). I wonder what percentage were pickup trucks, and I’m further interested in the gender breakdown of lane users.

Solving Dilemma Zones

I’m intrigued by the technology described in this article to reduce so-called “dilemma zones” — i.e., the moment when a light is turning yellow and an approaching driver is caught in a dilemma: They’re going to fast to stop yet they may still catch some of the red.

The report notes: “Indecision within the dilemma zone contributes to crashes at high-speed intersections. If a car is traveling at a steady speed or accelerating in that zone, the sensor relays that information to the traffic light, which will give the car a longer green light and time to clear the intersection.

My only question here is the “human factor.” If drivers know they are to be rewarded by gunning it towards the intersection, may not that also pose all kinds of risks? If a steady stream of fast vehicles keeps getting picked up by the sensor, adding time to the signal, when does the signal ever decide to change?

Audi’s Dumb New Smart Technology

Do you remember how, in the early days of the personal computer, you would constantly hear of all the amazing things you could do with it, such wondrous tasks as “balancing your checkbook”? In other words, you were being asked to spend a significant sum to do something that would more easily and efficiently be done on the cheapest calculator.

I get something of that vibe — I’ll call it “egregious technology” — from a new Audi project called “Travolution” (thanks Jalopnik), which the company describes as such:

“Communications modules built into each traffic light are able to send messages to cars in the vicinity, alerting them to the time remaining until their next green phase. The car’s onboard system is then able to calculate the speed which the driver must maintain in order to pass through the light during this green phase, and displays this via the Multi Media Interface display.”

In other words, the traffic lights send a signal to the approaching Audi, which then gives the driver an approach speed that will allow them to fluidly sail through the intersection, avoiding fuel-wasting stops and starts.

I’m skeptical of this for a few reasons. The first is that my 2001 Volvo already happens to have this technology. What’s more, it cost me nothing to add it.

What’s the wonder device? My brain. Partially because I like to drive in a way that maximizes fuel efficiency, and partially because I don’t get much of a kick at idling at traffic lights, I tend to slow down ahead of time if I see I’m approaching an intersection whose traffic signal is red (conversely, and who doesn’t do this, if I see the green is “fading,” based on flashing ped signals, I will speed up, within reason).

I’m constantly astounded how often, in New York City, drivers — particularly taxi drivers — often blaze past me, only to find themselves lingering at the light (maybe it’s because we’re wired to focus on short-term gains). Then, even though I was going slower to begin with, but because I haven’t had to make a complete stop, I typically drive right past them.

Avoiding unnecessary stopping and acceleration is one of the main precepts of “eco-driving” or “hyper-miling,” but it’s really just a function of being an alert, thinking driver (and some studies have noted the connection between fuel efficient driving and safe driving).

This leads me to my second big complaint with Audi’s system. Not only is it asking the driver to take their eyes off the road to look at a gauge to get information they could more or less discern by looking ahead, at the road, it presumably wouldn’t know things like the length of the queue of vehicles waiting at the light (unless, perhaps, they were all Audis) — so any stated approach speed might be completely inappropriate given the necessary start-up and clearance time of all the other vehicles. The simple fact of being given an approach speed for the intersection might induce some kind of “automatic” thinking, in which a driver may focus on maintaining the correct speed as their key task rather scanning the intersection (where close to half of all crashes occur) — in the way drivers can focus too much on the light itself rather than, say, vehicles that haven’t cleared the intersection for some reason.

Of course, being given the correct approach speed for hitting the green isn’t much help if you’re asked to approach at five miles an hour because the light is backed up with traffic. That’s why I suspect the money (not sure what Audi’s communicative lights would cost) would be better spent on lights that could talk to each other. Which we already have, of course, in some places — but even these need human help once in a while.

Left-lane Nudge?

Road Grooves, Groovy Road. Photo by ..::w::../Flickr

I’m always interested in unconventional solutions to traffic issues, and reader Paul up in Ontario sent along the following: “I observed recently that on a road under re-construction, the process involved grinding a rough surface on a lane prior to re-surfacing. On a multi-lane road, the lanes were not all surfaced at the same time. As a result, whenever a motorist encountered this “noisy” surface, they shifted to a lane with a smoother surface. As a result, the noisy lane became open!”

His idea would be to pave the left, or “passing” lane in such a way that a driver would presumably only stay in it for a bit before the ensuring vibration became annoying. This would solve the problem of “left-lane” bandits, people who camp out in the lane that is designated, by law or by norm, for passing slower traffic. People would make their passing maneuver, then move back into a lane to the right.

One issue, of course, is that for some people, the fastest drivers, the left-lane becomes their de facto lane, and they may force out dozens of drivers (necessitating all kinds of disruptive lane changes) for their own benefit. This raises another possibility. The road could be grooved in such a way, as in Japan’s Melody Road (that’s an engineer inspecting the road pictured above) to produce a certain sound at a certain speed. Grooving could presumably be laid so that drivers going over a certain speed produced a really grating, revulsive sound (music might be tricky as one person’s annoyance would be another’s delight). In a sort of Nudge-like way, drivers could choose to stay in the unpleasant lane if they wished, but they would be subtly steered toward the more harmonic travel lanes.

The grooves of the Melody Road, it has been suggested, can be rather powerful (and certainly more so than signage): “You need to keep the car windows closed to hear well,” wrote one Japanese blogger. “Driving too fast will sound like playing fast forward, while driving around 12mph has a slow-motion effect, making you almost car sick.” There you have it: Nausea, the new traffic calming device!

The concept has been demonstrated in Denmark as well, much earlier in fact, in the so-called “Asphaltotone,” the creation of artists Steen Krarup Jensen and Jakob Freud-Magnus, shown below (in Danish):

Grooves have already made their mark on road safety, of course. The so-called “Sonic Nap Alert Pattern,” or SNAP, was first tested on the Pennsylvania Turnpike in 1987 (after numerous instances of “drift off road” crashes due to fatigue and other causes). SNAP had the advantages of not being raised (the Turnpike had to be bare for snow-plowing), and being narrow, so repair and maintenance vehicles could traverse the roadside without obstruction. In time, the Turnpike saw a 70% reduction in DOR crashes after the shoulder rumble strips were installed. They too have a sound quality, of course: They get louder as you’re going faster, and engineers had to strive to adjust the pattern to make sure it was loud enough to be heard over the ambient sound of the car/truck interior.

Pretty groovy.

Bear Right

Ursus Automobilus

When I was at Tokyo’s incredible Kiddy Land toy store a few months ago, I was overwhelmed by the range of robots available (there was a “breathing” cat from Sega I really wanted but, alas, luggage weight restrictions). But I didn’t see anything like the creature reported in the Daily Telegraph. Not only does it give directions, but it warns when you’re driving too fast, detects the presence of booze, and even offers up local landmark info when it’s rubbed. Not sure what voice it speaks in, but if it’s anything like the Sprint Navigation device I’ve been using lately, that range of vocal stylings would include everything from “Rasta man” to “cab driver.” (I wish I were kidding).

I know backseat drivers, from Hyacinth Bucket on, get a bad name, but, for the majority of drivers on the road, having someone else in the car, as many studies have shown, is generally a good thing for one’s health (at least their physical health). Not only do they provide an extra pair of eyes, but they provide feedback about our own actions that we’re often less than aware of in the moment.

But still. I get so creeped out by people who load up the back window ledges of their cars with stuffed animals (reduced visibility=bad idea), I don’t think I’m ready to put one on the dash. Chuckie, maybe…
