Intersection warning systems activate on S.R. 46 in Brown and Monroe counties

BROWN/MONROE CO. – The Indiana Department of Transportation activated Intersection Conflict Warning System (ICWS) at two locations along State Road 46 in Brown and Monroe Counties on March 26.

The new systems are located at the intersections of S.R. 46 and Lower Schooner Road (Brown County), and S.R. 46 and Sewell Road (Monroe County).


Each ICWS includes signage and amber flashers to alert drivers of approaching traffic at two-way, stop-controlled intersections, typically a major road (higher traffic volume with no stop sign) and a minor road (lower traffic volume, with a stop sign). Under-pavement vehicle detection equipment allows the system to notify motorists in real-time of traffic approaching an intersection or traffic waiting to enter an intersection.


The purpose of ICWS is to improve traffic safety. According to the Federal Highway Administration, the systems can reduce severe crashes by 20 to 30 percent. Drivers should still exercise caution when approaching or entering intersections, even when lights are not flashing.

A total of five systems will be installed in southeastern Indiana, and more than 15 statewide.
