2007 National Traffic Signal Report Card

  • The nation’s state of traffic signals affects commuters nationwide. Improperly timed signals contribute to increased delays, wasted fuel and negative impacts on the environment.

  • Small changes can make a big difference, as evidenced by 58 agencies that had an improved grade from the 2005 National Traffic Signal Report Card. Case studies outlined in the 2007 National Traffic Signal Executive Summary show that proactive actions can lead to significant improvements with immediate operational benefits.

  • Traffic signal timing is a good investment. Few dollars can result in big benefits. Studies around the country show that the benefits of investing in signal timing improvements outweigh the costs by 40:1, which can results in benefits of as much as $45 billion per year. This corresponds to a price of less than $3 per U.S. household resulting in savings of $100 per household per year.

  • It is estimated that poor traffic signal timing accounts for 5 to 10 percent of all traffic delay or 295 million vehicle-hours of delay on major roadways alone.

  • The 2007 National Traffic Signal Report Card provides a road map to success. Several new tools and resources have been developed to assist agencies in improving operational conditions.
