New Fiber Optic Technology to Speed Traffic and Cut Pollution
N class=story-body>RALEIGH -- A $28 million high-tech upgrade for Raleigh's traffic signal system, which won preliminary approval Wednesday, will add zip to the crosstown trip.
Drivers will notice the difference, transportation engineers say. They'll see more green lights. They'll waste less time at red lights. They'll get where they're going more quickly. They'll burn less gas.
And their cars won't spew so much pollution.
"This will do more for air quality than anything else we could possibly do," Joe Bryan of Knightdale, chairman of the Capital Area Metropolitan Planning Organization, said Wednesday. The board approved $21 million in federal clean-air money for the traffic signal project, to be matched with $7 million in city capital improvement money.
