Many of you have ridden this highway in SW Colorado. It will be interesting to see if it works.

Car-wildlife wrecks illuminated
CDOT to test special lighting along a risky stretch of U.S. 160. The pilot project is designed to shine a spotlight on animals near the pavement, making drivers aware of the hazards and encouraging them to slow down.

Durango - One of the state's most dangerous stretches of highway for wildlife-vehicle collisions, U.S. 160 between Durango and Bayfield, will be the testing ground for a first-of-its-kind safety system of special lighting.

Colorado Department of Transportation engineer Mike Vaughn said the research project is unique in the country. The idea is to illuminate the animals with motion-sensing light-emitting diodes mounted on roadside poles 8 to 10 feet high. The lights will turn on when wild animals move along the pavement.

Vaughn said he hopes the illumination will make drivers aware of the hazards and encourage them to slow down.

Maintenance workers began clearing brush Wednesday on a 3-mile stretch of U.S. 160 west of Gem Village. The lights will go up after CDOT completes its study of various motion-detection systems.

CDOT has $100,000 in federal research funds and $25,000 in state funds for the project.

As part of the pilot project, CDOT will clear only brush along a second section to compare its effectiveness against clearing and lighting. Monitoring of the test sections will continue for two to three years, depending on how long it takes to get data to draw statistically valid conclusions, CDOT said.

Wildlife-vehicle collisions are a significant problem in Colorado and nationwide. In 2003, the last year for which statistics were available, CDOT reported 300 injury-causing crashes and 3,600 property-damaging crashes involving wild animals on Colorado roads.

The National Highway Traffic Safety Administration estimated that accidents involving animals cause an average of 200 deaths a year nationwide.

Roadway fencing is known to be effective, but it is costly and interferes with the migration of wild animals, even promoting inbreeding, CDOT officials said.

"High fencing is really hard on animal populations," says Colorado Division of Wildlife spokesman Joe Lewandowski in Durango. "Fences really disrupt their cycles. The DOW helped with the planning of this lighting project, but we have no idea how it will work out.

"The idea is to get people to slow down."

Apparently, they're using a similar system on the Ohio Turnpike.

Other interesting options use passive or active infrared technology. A Canadian company has been developing a similar stationary pole-mounted system (http://www.10meters.com/qwip_ir.html). Cadillac used to offer a passive infrared system (http://www.businessweek.com/technology/content/sep2004/tc20040914_2165_tc178.htm) in its Deville cars, as did Lexus in a few high-end models. But high cost and poor performance led to a drop in sales of those units, so they have been discontinued.

Honda now offers an improved passive infrared system (http://www.driveandstayalive.com/info%20section/news/individual%20news%20articles/y_041025_honda-intelligent-night-vision-system.htm) in Japan, and is considering bringing it to Europe and the US. Lexus and Ford are now developing more active near-infrared technologies, but they're still a ways out.

Meanwhile, a European consortium is trying to develop a low-cost night vision system (http://optics.org/articles/ole/10/1/3/1). If they can bring the costs down and the quality up, we may start seeing these systems offered in more new cars.

No word yet on whether these systems will be made small enough to fit into a rifle scope.

I have read some research that if they use a combination of fencing and they build underpasses for animals to cross over it would pay for itself in a short time on major roads in rural areas.

Spew, gag, spit, cough. I don't think my lungs can process oxygen properly anymore. ROTFLMAO!

You're welcome, El Jeffe. ;)

Of course, I was thinking about the deer. It hadn't occurred to me that these systems are being optimized to recognize pedestrians. Hm.

Don't know about "paying for itself" in that a bridge over a divided highway could easily run $4 mil. and much more. That is a proposal that is being considered for the heavily traveled areas, and trying to to be rammed down the throat of any nearby developer, e.g.: Vail Resort.

Might work. Then Meese wouldn't need the scope; just stand on top of the bridge and yell, "Pull!"

Hey there, I'm not the one with the firearms fetish. Just trying to accept those who I may disagree with. ;)

They have deer overpasses on I-80 in NJ & PA. I don't know if they work 'cause that road has to have the most roadkill per mile of any stretch of road in the country. I counted 8 deer on a 1 mile stretch :eek:

Or maybe the the dead deer didn't make the training session :rolleyes:

reminds me of the joke....

A woman calls the state highway department. She wants them to move the "deer crossing" signs further down the road to a straight, level, well lit area. Highway department says Huh? Yes, she says, if they move the sign, then the deer will cross where drivers can see them, instead in the middle of this wooded area.


I think that was originally some sort of "blonde" joke.
