DuPage County, Naperville to Connect Traffic Signal Systems

DuPage County will expand the Division of Transportation (DuDOT) Central Signal System later this year, including connecting its system with the City of Naperville.

The Central Signal System allows DuDOT to remotely monitor and observe traffic operations and make adjustments based on changing conditions. Currently, the system includes 72 traffic signals, which will grow to approximately 200 signals after the expansion. There will be 60 cameras in operation on the County highway system that can be remotely accessed to observe traffic operations and road conditions.

“This partnership will allow an easier flow of traffic for motorists in DuPage County, and allow both DuPage County and Naperville to collaborate on traffic adjustments as needed, allowing for better coordination and synchronization to improve traffic flow,” said Don Puchalski, Chairman of the DuPage County Transportation Committee. 

“The City of Naperville has been working on its centralized traffic management system to minimize travel times throughout our community since 2016,” said Bill Novack, Naperville’s Director of Transportation, Engineering and Development. “In 2017, we installed equipment along Washington Street in our effort to modernize our signal system. Connecting with DuPage County’s system is the next step towards our goal to allow real-time, system-wide remote programming and operation.”

The total project costs is $4.5 million, a majority of which is provided by federal funding. Necessary construction is expected to begin in 2019.

The County Board is expected to approve an intergovernmental agreement to connect with Naperville’s system at its March 13 meeting.
