New research suggests that traffic noise (apart from pollution and general hectic motion) degrades the natural habitat of songbirds, and perhaps other animals. Boise State University biologists created a "phantom road" using speakers to create traffic noise in a natural, roadless songbird habitat. Read the rest

Mr. Hagar, in Europe you can and will drive 55.
In a move to reduce the 30,000 annual traffic fatalities in Europe each year, the European Union is planning to equip cars with technology that senses the speed limit and applies the brakes if the car is speeding.
The scheme would work either using satellites, which would communicate limits to cars automatically, or using cameras to read road signs. Drivers can be given a warning of the speed limit, or their speed could be controlled automatically under the new measures.
EU plans to fit all cars with speed limiters (Thanks, Matthew!)
Update: From the Blogs of the European Commission: “The Commission has supported past research into ISA. There is a current stakeholder consultation and study focusing on speed limiting technology already fitted to HGVs and buses. One aspect of that is whether ISA could in the long-term be an alternative. And a second consultation on in-vehicle safety systems in general. Taking account of the consultation results, the Commission will publish in the autumn a document by its technical experts which will no doubt refer to ISA among many other things. That is all. (NB such 'staff working documents' are not adopted by the Commission at political level and have no legal status.) Nothing more is expected in the foreseeable future." Read the rest
Update: I've updated the link to Bill Beaty's original article -- the one I linked to originally was a scumbag plagiarist.
Jeffrey sez, "A fascinating article about what causes traffic jams, and how to drive differently to help ease 'stop and go' traffic. It is interesting to see how basic human instincts (or maybe just the way we have been taught how to drive) can turn a crowded road into one that is jammed with stop and go traffic. It is probable that self-driving cars will eliminate many of these issues before many humans have time to learn these techniques. However, it is very encouraging to hear the author's anecdote about how he was able to singlehandedly erase a traffic jam in his own lane:"

On a day when I immediately started hitting the usual "waves" of stopped traffic, I decided to drive slow. Rather than repeatedly rushing ahead with everyone else, only to come to a halt, I decided to try to drive at the average speed of the traffic. I let a huge gap open up ahead of me, and timed things so I was arriving at the next "stop-wave" just as the last red brake lights were turning off ahead of me. It certainly felt weird to have that huge empty space ahead of me, but I knew I was driving no slower than anyone else. Sometimes I hit it just right and never had to touch the brakes at all, but sometimes I was too fast or slow.
I've heard anecdotal evidence that lifesize cardboard cut-outs of police officers in shops can deter shoplifting. Now Bangalore police are using the same method to deter traffic violators. "It is not a gimmick. Wherever we have put up these cut outs, violations have come down," Traffic Commissioner MA Saleem told the BBC

Suzanne Paulson, UCLA professor of atmospheric and oceanic sciences, saw "Carmageddon" as an opportunity to make use of a "natural experiment." She and a colleague "measured pollutants in the air during the LA freeway shutdown last year, and have now released their findings.
Air quality near the normally busy highway improved by 83 percent that day last July, relative to comparable weekends. Elsewhere in West Los Angeles, the improvement was equally dramatic. Air quality improved by 75 percent on that side of the city and in Santa Monica, and by 25 percent throughout the entire region, as a measure of the drop in ultrafine particulate matter associated with tailpipe emissions.
"We saw what we expected: you take motor vehicles away, the air gets really, really clean," Paulson says, "which tells us that most of the pollution is from motor vehicles from one type or another in this area."
