Naperville Coordinated Traffic Signal Network
Description
Long term plan to integrate all of Naperville's closed loop systems into a coordinated traffic signal network. The initial phase consists of Washington Street signal system improvements, which will create a north/south spine by combining three existing interconnected signal systems that will communicate with centralized traffic management system software. Additional signal systems will be added to the network in future phases.
