KU researchers study use of blue light signal

Police Lights

LAWRENCE, Kan. (AP) — Researchers at the University of Kansas are experimenting with using a blue light to help law enforcement officers nab red-light runners.

Here’s how the system works: Blue lights come on when traffic signals turns red, providing a visual clue to officers. The university says the blue light is visible from 360 degrees. That way even if officers can’t directly see the traffic signal change, they can still know that a motorist ran a red light.

Blue confirmation light systems are being installed at two intersections in Lawrence and two in Overland Park.

Researchers from the university’s School of Engineering will monitor the system’s effectiveness during the next six months. Funding for the project comes from the Kansas Department of Transportation and the Mid-America Transportation Center.
