Lake County expanding 'central nervous system' of traffic flow

Getting your Trinity Audio player ready...

The Lake County Board recently approved $1.2 million for Lake County PASSAGE, which will go toward expanding the 20-year-old network acting as the “central nervous system” of Lake County roadways.

At the county’s Libertyville campus, the Transportation Management Center is something of a miniature NASA control room: A few pairs of desks and computers face a wall of screens, displaying views of intersections across the county.

From there, Lake County Department of Transportation engineers and staffers track, analyze and manage drivers’ daily commute, all part of what’s known as Lake County PASSAGE.

PASSAGE’s work is largely invisible to everyday drivers, but behind the scenes, their engineers are always looking at how to improve traffic flow.
