VDOT’s $36 million Active Traffic Management System (ATMS) was put in place last year along a 30-mile stretch of I-66 from the D.C. line through Arlington, Fairfax and Prince William counties with the goal of making the most of the available lanes. I-66 is truly multimodal – with many single drivers, bus commuters, carpoolers—as well as those using Metrorail, which runs in the median. It is in high demand, moving more than 175,000 vehicles a day, with congestion during rush hours, off-peak and even on the weekends. The system includes new overhead gantries, incident, blockage and queue detection, increased traffic camera coverage, advisory variable speed limits and dynamic hard shoulder running and ramp metering systems. ATMS has succeeded by managing traffic during incidents, keeping traffic flowing and reducing congestion-related crashes, making commuters safer and happier on their travels.
