After launching their Active Traffic Management system on Interstate 66 last fall, Virginia transportation planners have been looking for more ways to use the electronic communication system to improve traffic flow.
They think they have found one at the Route 28 interchange in Centreville, a notorious spot for slow traffic during rush hours.
The planners think they can help with one part of a larger problem. It’s the queue of slow-moving traffic that forms on weekday mornings as drivers heading west on I-66 line up to exit onto northbound Route 28. This gets messy, because some drivers who want to exit don’t get in the right lane in a timely fashion, so they slow down and look for a place to squeeze in before they pass the exit. And then there are through drivers who get caught up in the slow-moving traffic on the right, so they try to get left into faster-moving traffic.
