Traffic Signals

Traffic signal operations receive poor grades

This comes as no surprise to people who play the red-light-green-light game. A new survey says the country's traffic signals are inefficient and need some work.

It was prepared by a coalition that included the Federal Highway Administration and various transportation groups. The report says out-of-whack signals cause too much stop-and-go traffic, which frustrates drivers, wastes gas and increases air pollution. The report says most areas don't have a viable plan for traffic signal operation, don't have the staff to monitor traffic before and after normal work hours, and don't conduct regular reviews. It may be a matter of money.

The report estimates that improving the system could cost about 965 million dollars a year.
