Will County Approves Intergovernmental Agreements to Add Intelligent Traffic Systems at Several Intersections
Summary
The Highway Committee approved intergovernmental agreements to incorporate intelligent traffic system (ITS) components at intersections along Plainfield‑Naperville Road; county traffic staff said the systems can include radar, video and pavement detectors and allow remote monitoring, but data‑storage details remain to be determined.
The Will County Highway Committee approved intergovernmental agreements to add intelligent traffic system (ITS) components at multiple Plainfield‑Naperville Road intersections, county staff said.
One agreement covers the intersection of Plainfield‑Naperville Road (County Highway 14) and Mountain Road; a second agreement covers Plainfield‑Naperville Road at Rodeo Drive and 119th Street. The committee voted to approve the agreements during the meeting; motions passed with routine roll calls.
Paul Dehart, the county's traffic engineer, described ITS as a family of detection and control technologies that can include pavement detectors, radar and video cameras. "Intelligent doesn't just mean cameras. It means better ways of handling traffic movements," Dehart said. He said the agreements give the county and its traffic engineer greater ability to modify timings and control signals remotely instead of relying solely on an external maintenance contractor.
Dehart said camera systems can be used both for detection and for video, and that ITS allows the county to "react and actually observe the signals, remotely." A committee member asked whether captured video would be stored; the county engineer said he did not recall details on data retention and that the issue "will get flushed out" when the county brings a related contract for ITS software and equipment in the next month or two.
The committee was told the upgrades are intended to allow remote observation and quicker response to incidents and to reduce recurring contractor dispatch costs. The motions to approve the intergovernmental agreements passed.
