The Washington State Department of Transportation has spent the past few months installing a series of upgrades to its traffic management system along Interstate 5 through Vancouver. Some of the new technology is scheduled to go live starting today.
The agency announced Wednesday that it will begin using newly installed ramp meters at the Northeast 78th Street, Main Street, state Highway 500, Fourth Plain Boulevard, Mill Plain Boulevard and State Highway 14 interchanges. The meters activate in response to the real-time traffic conditions to help reduce congestion along the corridor.
The upgrades also included new overhead electronic message signs, advisory speed limit signs, and cameras and pavement sensors to monitor traffic and weather. Those other components are scheduled to go live Tuesday.
