New research shows how easy it is to infiltrate key traffic-control systems

The next time Gov. Chris Christie wants to create traffic problems on the George Washington Bridge, he may have more sophisticated options than an old-fashioned study.

AddInvention turns traffic lights into a game to ease congestion

Sometimes, we get angry being stuck in traffic. We might be fuming about the person playing on their cellphone that rear-ended someone, or we might blame the person poking along in the left lane. And yes, sometimes, we might just blame the oppressive injustice doled out by traffic lights, particularly when we hit every... single... red.

59Florida DOT quietly changed yellow-light standards, municipalities issuing more tickets

Red light cameras don't appear to be going away, so it should come as no surprise that neither are the controversies around them. We're told again and again that they're about safety, not revenue collection, yet year after year, the studies and headlines compete to support and tear down those arguments. An investigative report by Florida's WTSP Channel 10 News gets the maelstrom whirling again, having found that various state municipalities have shorted yellow light times to below those recommen

While smaller municipalities have followed similar plans in the past, LA is the first major city to take a stab at getting all of its lights to play nice together. If it works, the new system could increase average traffic speeds by 16 percent and reduce travel times by 12 percent. We imaging reducing the amount of time cars spend idling at a stop light should help reduce fue

18How insects might help make traffic lights smarter and more efficient

18Cleaner, more efficient transportation infrastructure better for the environment economy

Finding the nexus where different groups – hardcore environmentalists and hardcore business-firsters, for example – share common ground isn't always easy. Today, we think we've got one: smarter, greener transportation systems.

50Unintended Consequence of Technology: New LED traffic lights can't melt snow

Traffic lights using state-of-the-art LED illumination use 90 percent less electricity, offer a much longer service life and are more durable than their incandescent counterparts. Taking advantage of the countless benefits, cities around the country have been replacing traditional filament-based traffic signal bulbs with LEDs for years. Unfortunately, the low-watt LED units burn much cooler than its white-hot counterpart making it unable to melt snow off weather exposed traffic fixtures.

34Editorial: A simple way to reduce SoCal pollution and fuel consumption

As I spent several days in Los Angeles, CA last week I came to several realizations. First I never want to live there. While air quality has dramatically improved since the 1960s, the geography of the region means that it will never be as good as other places. Since the 1960s, California politicians and regulators have continually tightened emissions standards to the point where more than 99 percent of the pollution produced by cars and trucks in those days has been eliminated, and yet they want
