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.

    Smart technology keeps infrastructure operating safely
    US Departments of Transportation (DOTs) are using smart technology to warn civil engineers when something is wrong with the infrastructure, says the American Association of State Highway and Transportation Association (AASHTO). Sensors installed on bridges, in roadways, and on maintenance vehicles are communicating real-time performance and weather data, allowing engineers to solve problems before they occur. "Most people look at a road or a bridge and never realise the technology that today's modern tra

Here, the company's Stephen Clark talks about the technology being used. In England, the Highways Agency's (the HA, an executive agency of the Department for Transport) Managed Motorways system - formerly called Active Traffic Management - uses electronic signs and signals mounted on gantries to direct drivers

    Driver aids make inroads on improving safety
    In-vehicle anti-collision systems continue to evolve and could eliminate some incidents altogether. John Kendall rounds up the current developments. A few weeks ago, I watched a driver reverse a car from a parking bay at right angles to the road, straight into a car driving along the road. The accident happened at walking pace, no-one was hurt and both cars had body panels that regain their shape after a low speed shunt.
