Lake County Signal Interconnects

Description

Communications between traffic signals. Some are already interconnected, and the system is being expanded. As the system is developed, linked traffic signals also communicate with the Lake County Traffic Management Center central control.

LCDOT expanded its county–wide communications backbone using fiber optic cable, wireless radios, and cellular technology – all LCDOT owned intersections are online and nearly all signalized intersections in Lake County (including IDOT and local municipalities) are now connected to our TMC in Libertyville. LCDOT is also currently building redundant fiber loops to eliminate single–point failures.
