As we head deeper into autumn, the landscape is treating us to a spectacular parade of orange, yellow and red hues.  Yes, turn signals and brake lights at rush hour are indeed a sight to behold.  But it’s more fun to wax poetic about the fall leaves.  So, frolic in the foliage and rake in this latest edition of Merging Lanes.

Smog-Eating Concrete

In the future green economy of America, the streets won’t be paved with gold.  They’ll be paved with titanium dioxide.  Demonstrating that innovation knows no boundaries in the shared space between transportation and air quality, engineers in Missouri recently laid down a 1,500-foot strip of asphalt that can break down ground-level ozone pollution.  Mixed into this special blend of concrete is a titanium dioxide additive that creates a photo-catalytic reaction, absorbing smog, using sunlight to break it down, and releasing it as nitrogen and carbon dioxide.  Neat.

The Morning Ritual That’s Ruining Your Car’s Engine

With the chill of autumn comes those frosty mornings that all commuters must endure.  But there’s one driveway ritual that Georgia commuters should stop practicing because it can ruin a car’s performance.  Warming up the engine in the mornings by allowing it to idle can actually wear down engine parts and create more air pollution.  The practice of unnecessary idling on cold mornings can produce up to six grams of carbon monoxide per minute.  That’s equal to the carbon monoxide content from three packs of cigarettes.  Turns out, it’s also an easy way to get your car stolen.  Simply put, the best way to warm up your engine and create less air pollution on your morning commute is to drive your vehicle instead of idling.

Where the Germs Are

If you need extra motivation to drive less, look no further.  From the Yuck Department, a new study found that gas pump handles may be among the dirtiest surfaces that we touch.  A team of hygienists conducted tests in six cities – including Atlanta – and determined that gas pump and mailbox handles, escalator rails and ATM buttons were more likely to harbor high concentrations of germs that can lead to illness.  In all, 71% of gas pump handles tested had high contamination levels.  Gross!

Families Trapped in Vehicles
The headline of a recent article in Time magazine points out the depth of America’s car culture: “We Pay More to Drive Than We Spend on Taxes.”  Citing a new study conducted by a Washington, D.C. think tank, the article describes how difficult it is for the average American family to scale back on driving costs, even in the face of higher energy prices that influence everything from the cost of a gallon of gasoline to a gallon of milk.  Over the past decade, The Clean Air Campaign and its partners have helped more than 85,000 Georgia commuters get relief from the high cost of commuting through a combination of financial incentives and support programs.  We’re ready to help more people make their dollars go further by using commute options.
