WASHINGTON — Fine-tuning controls on the nation's traffic signals would cut U.S. road congestion by as much as 10 percent, transportation experts estimate.
It would also reduce air pollution from vehicles by as much as a fifth, cut accidents at intersections and save about five tanks of gas annually per household, according to the National Transportation Operations Coalition, an alliance of federal, state and local traffic departments and equipment-makers.
That's the good news. The bad news is that the average local traffic department earned an overall grade of D on the alliance's latest report card. Streamlining intersections is happening in only some cities and states, even though it's eminently doable.
"People who say we can't do anything about congestion are wrong. We can do lots," said Joel Marcuson, a specialist in urban intersections who's with the Jacobs Engineering Group Inc. in Phoenix.
Right now, however, three out of four of the nation's 300,000 traffic signals need replacement or timing adjustments for optimum performance, according to the U.S. Department of Transportation. |
