Virginia installs ATM to ease congestion on I-66

The Virginia Department of Transportation (VDOT) has begun work on installing an active traffic management |(ATM) system on interstate 66 through Arlington, Fairfax and Prince William counties from the Washington, DC line to Route 29 in Gainesville. Designed and built by TransCore, the system is intended to improve safety and incident management and will include new sign gantries, shoulder and lane control signs, speed displays, incident and queue detection, and increased traffic camera coverage.

The 1747 Virginia Department of Transportation (VDOT) has begun work on installing an active traffic management |(ATM) system on interstate 66 through Arlington, Fairfax and Prince William counties from the Washington, DC line to Route 29 in Gainesville.  

Designed and built by 139 TransCore, the system is intended to improve safety and incident management and will include new sign gantries, shoulder and lane control signs, speed displays, incident and queue detection, and increased traffic camera coverage.

Sensors, traffic cameras and overhead signs will enable VDOT to change the signs to give drivers real time advance information on upcoming traffic, crashes, congestion or closed lanes. VDOT hopes that getting people out of closed lanes before they reach incidents will make the slowdowns less abrupt and less severe. If there is standard traffic, the signs could be changed to give drivers a warning about exactly how far away the congestion begins.

Although ATM is a relatively new concept in managing traffic in the United States, it is popular in Europe, such as the Highways Agency’s smart motorways project in the UK.

    Active traffic management - challenges and benefits
    Minnesota DoT has built one of the most intensive Active Traffic Management (ATM) systems on the road today. Like many ITS deployments, the state has gained benefits but also faces many challenges, as Pete Goldin reports. Smart Lanes is the brand name of Minnesota Department of Transportation’s (MnDoT) ATM system on I-35W in the Twin Cities Metro Area. The original system covered 16 miles of I-35W south of Minneapolis starting in 2009, and was extended by two miles in 2011. Additional ATM equipment was inst
