Road Marker Marks You

michael posted more than 9 years ago | from the in-soviet-russia dept.

Privacy 731

If you could make a reflective road marker (a "road stud", in the jargon) that contained a small solar cell and battery, you would be able to: A) power a LED at night to provide lit lanes, not just reflection; B) monitor for fog or water on the road surface; C) monitor the temperature to detect ice; D) use infrared ranging and embedded cameras to detect and report the license number of anyone speeding on the road; E) All of the above. If the company can make them cheap enough, they'll be everywhere in a few years.

The story is the Soviet Russia joke. "In Soviet Russia, road markers mark you!" It doesn't get any more straightfoward. By reversing it you'd have something like: "In Soviet Russia, you mark the road... wait."

In a Road That's All Eyes, the Driver Finds an Ally
By IAN AUSTEN

ABOUT 12 years ago, Martin Dicks was trapped in dense fog during a harrowing four-hour commute to his job as a firefighter in central London.

"Virtually all I could see on the road was a cat's-eye reflector every now and then," Mr. Dicks said, recalling his trip down one of Britain's major highways. "I figured that if I could make the cat's-eyes more visible, I could probably save more lives than I could in the fire service."

A back injury forced Mr. Dicks out of the fire department shortly afterward, giving him the time to pursue that goal. His training as an electrical engineer provided the necessary skills.

Now, after perfecting illuminated markers that are embedded in the road surface to guide motorists through bad weather or warn of dangerous conditions, Mr. Dicks's company, Astucia Traffic Management Systems, is going a step further. Its latest creation is an embedded stud equipped with a camera that catches speeders, monitors traffic for criminals or stolen cars and even checks for bald tires on the fly.

"Nobody knows it's a camera or a speed trap," Mr. Dicks said of his latest creation.

Mr. Dicks's original idea was quite simple in concept. He wanted to create an illuminated road marker containing its own power source, a solar cell. At night or in bad weather, light from approaching vehicles would generate enough power to light up the marker, which consisted of light-emitting diodes. An illuminated marker would be more visible than a plain reflector, and the idea was that a car passing over the markers would cause them to stay illuminated long enough so that they would provide a warning trail of lights for any vehicles close behind.

The trouble, at first, was the technology available in the early 1990's. Photovoltaic cells were not as efficient as they are today. And at the time, Mr. Dicks recalled, "the concept of a white L.E.D. was nowhere."

Working mostly with family members at first, Mr. Dicks produced a prototype marker within two years. He dodged the white L.E.D. problem by combining the glow from red, green and blue arrays. The group not only overcame the limitations of solar cells, but also managed to engineer markers that turned red to warn when the gap between two cars was dangerously small.

Mr. Dicks said the technology both impressed and alarmed British government highway officials.

"They were frightened about everyone using the product on roads from one end of the country to the other," he said. "They thought it would make their budgets disappear."

The first markers cost roughly twice the price of conventional embedded road studs. As a result, their use was restricted at first to especially fog-prone or dangerous sections of roads as well as crosswalks, including some in the United States.

Mr. Dicks was not the only person with a desire to illuminate to road markers. After a friend struck and killed a pedestrian in 1991 at a crosswalk in Santa Rosa, Calif., Michael Harrison developed a system that uses flashing L.E.D.'s in the road surface to make crosswalks more visible. The company he founded in 1994, LightGuard Systems, now has about 700 installations in the United States.

A study of 100 illuminated crosswalks by Katz, Okitsu & Associates, a traffic engineering firm based in Southern California, estimates that adding the blinking L.E.D.'s to crosswalks can reduce pedestrian accidents by 80 percent.

The original Astucia markers were glued onto the road surface. That left them vulnerable to snowplow blades and to constant pounding from car and truck tires.

Mr. Dicks wanted to put the markers into holes drilled into the road surface. The key, he said, was finding self-healing resins for the top lenses that would be flush with the surface and subjected to much wear and tear.

"It's like running your fingernail on a rubber sheet," he said of the plastics' behavior. "The mark it leaves goes away."

Advances in solar-panel technology also allowed Astucia to develop markers that could store electricity all day and then constantly illuminate particularly dangerous sections of roads at night.

Other features followed. Optical systems inside the casing are able to monitor the atmosphere for fog. Electrical resistance detectors can check for standing water. The addition of a thermometer allows the marker to predict ice.

But getting high-resolution digital cameras into the flush-mounted housings was a more difficult task. It ultimately required the development of a special series of lenses that in effect allowed the camera to look upward and forward from its subsurface location.

The cameras (the system can use either normal or infrared sensors) provide remarkably detailed images, according to Mr. Dicks. "You can clearly see everything underneath a vehicle, although I'm not sure why you'd want to do that," he said.

The police, however, are likely to be interested in seeing the license plates of vehicles traveling above the speed limit or through red lights. To that end, Astucia has developed a system that is operating on a highway in Scotland. It employs three embedded cameras to give front, rear and side views of passing vehicles. Other embedded sensors project two infrared beams over the road that are used to time traffic and determine its speed. The images and the speed data travel under the road by cable to a computer. It in turn relays the data by satellite to Astucia's offices.

The system is currently being used to monitor traffic slowdowns. When it detects them, it turns on illuminated markers farther up the road as a warning. Mr. Dicks said that its speed measurements were accurate within 0.5 percent, well within the tolerances demanded for traffic enforcement.

Similarly, he said, the systems can be combined with optical character recognition software to automatically track stolen vehicles or cars believed to be used by suspected criminals or terrorists.

The United States branch of Astucia began demonstrating the camera system - which costs about $50,000 for a package of three cameras, sensors and supporting electronics - to police and highway officials less than a month ago. John Kerridge, the subsidiary's president, reported considerable interest in the system for both traffic and broader law enforcement. But he added that public resistance could be one obstacle to its adoption.

"We all break the law regarding speeding," Mr. Kerridge said. "The system may leave a bad taste in motorists' mouths at the beginning. But when their insurance starts going down and stolen vehicles start getting recovered, the benefits will overcome that."

Those little studs are great. There's some newly paves roads in our area that have long curves with steep dropoffs and the painted lines really don't show up well on rainy nights.

They placed the road studs on one of these roads and they practically glow compared to the paint. If the self-illuminating kind become readily available and easily placed it would be great for areas that see a lot of inclement weather.

Might cut down on the number of oncoming cars that drift into my lane on during the commute home as well. Now if we could just jam cell phone use in cars.

What would be very cool (5, Interesting)

obfuscated (258084) | more than 9 years ago | (#9155831)

is if the government started putting leds embedded into the pavement and they could send you messages (eg. accident up ahead, work zone, speed limit changed to XXmph, etc) to you while you're driving having the message pace with your car.

Also, you could make lanes that are dynamic during the day and night. (They already have those with changing street signs).

Real time stopping distance approxomations (are you following too close?). Lane change "handoffs" (the road infront of you goes orange because someone is turning into that lane.)

It's would be the same technology used for those rotating led clocks.

Of course, it'll all be moot when people finally let computers do the driving for them.

Now for on topic stuff... I like the idea of flashing lights for crosswalks, but not so much the cameras. It's sort of messed up to think that every single reflector in the road can be a camera.

Also, at what point does this start becoming a distraction? Can I see the lights from my front window? Being LEDs, I would hope not, but it'd be nice to know. I also would be interested in seeing whether these things stand up to the weight of a Chicago winter... regardless of what the article says. :-)

As I say every time this subject comes up, I'd much rather have my car know the max speed on a given road for a given set of conditions and not be allowed to go over the max speed, than I want fancy electronics to check to see if I go over the max speed, and if I do, take my picture, and send me a ticket. I'd rather pay higher taxes than fund police through tickets (and we wouldn't need as much traffic police either if the cars were smarter).

I claim that if no one could go over the speed limit, traffic would flow much more smoothly, and if the limit is too low (because you are expected to speed 10 mph), we will all complain loudly enough to get it changed.

Other aspects of this project sound interesting though.

While I'm willing to applaud better-lit roads, why incorporate speed traps? Increased revenue to pay for the little buggers? Do we really want (or need) tiny cameras posted all along our highways seeing to it that we behave? I mean, I guess it could be argued that if you obey the law you have nothing to fear, but this just makes me uneasy. What next? Crosswalks that take a picture of you when you jaywalk--even if it's midnight and there's no traffic? I thought this was 2004, not 1984...

...ever since I saw embedded reflectors in the UK. Problem is, where I live, we get large amounts of snow and ice building up on the roads. Sometimes when I'm driving on the highway, my mind will turn to the notion of holographic lane markers... or some equivalent system that would interact with the windshield of the car to visibly plot lanes etc... How about it, physicists of /.? Any brilliant ideas?

similar idea (2, Interesting)

In a pretty recent issue of Spectrum (the IEEE "trade" mag), there was a piece on a sensor network being used on an island off Massachusetts to study birds that lived on an island in that region.

The sensor were about the size of golf balls, and had sensors for info like temperature, humidity, etc., were battery powered, and capable of creating their own network along which they could relay info.

Here, sounds like they're trading size for range of functions - but that's to be expected. Sensors, sensors, everywhere, and where does all that info go ...

Oh Great. (1)

This would start an entire market for products designed to foil these things. Let's see: james bond style license plate rotators. Those defraction grating thinies that mean you can only view the plate from head on, not from an angle. You could speed as long as you don't change lanes. I'm sure someone can come up with an electronic device that can burn out the dots. I bet all of these products would be sold by the company that sells the dots. It would be another arms race just like the radar detector detector detectors.

My first reaction is:

LED lit roads - good
Roads that track you everywhere you go - Bad

So why does such a good idea have to become "real-world bloatware"?

The system is currently being used to monitor traffic slowdowns.

And if you want an abundance of those slowdowns to monitor, just also use the device's ubiquitous radar/camera feature to rigorously enforce posted highway speed-limits during peak travel. (...at least on those highways where traffic still currently flows.)

So they'll be densely scattering batteries all over our roads? Batteries have such pleasant chemicals inside.

For universal speed-limit enforcement! (1)

I am all for it. Once everybody starts getting tickets for speeding, the limits will rise to sensible levels (or are abandoned entirely).

Speed enforcement (5, Interesting)

The markers will probably be useful for detecting fog and leaving a light trail after cars. Speed cameras are best placed on vertical structures where the lens is less likely to get covered with ice/snow/road grime/spray paint and where the lens is also best positioned to view license plates. Besides, we'll probably all go to RFIDs in cars within a few years :) Automated enforcement of speed laws is actually illlegal in many jurisdictions like NJ and PA (in PA local cops aren't even allowed to use RADAR or laser). Something about the right to face your accuser...

This is definitely fascinating stuff. Medium-sized town Veerhoeszjen in The Netherlands has actually been trying these devices out for the last few months, and a href="http://69.93.68.74/article_view?id=291
