City pursues three WISDOT CMAQ grants to modernize traffic signals and communications
Summary
Engineering staff described three CMAQ-funded projects — controller replacement ($275,280; city share $63,056), fiber-radio connectivity ($271,865; city share ~$62,373), and ATMS software ($185,000; city share $45,000) — to improve signal coordination and maintenance; the committee approved the state municipal agreements unanimously.
City engineering staff told the committee the city operates 42 traffic signals on multiple controller models, some of which lack Ethernet and have power issues. The committee approved three state municipal agreements (SMAs) and associated CMAQ grants to upgrade controllers, add remote communications via fiber radio, and install advanced traffic-management software.
Mr. Mack said the controller-replacement grant totals $275,280; "the grant will reimburse $212,224 and the city would fund $63,056 to replace 38 of the 42 traffic signal controllers." He described how standardizing controllers and adding Ethernet-capable units will ease maintenance and reduce technician confusion across varying models.
The second CMAQ grant would fund fiber-radio links to bring cabinet communications back to City Hall (total $271,865; state reimbursement $209,492) to improve remote diagnostics and reduce unnecessary truck rolls. The third grant would pay for ATMS software ($185,000), enabling automated timing adjustments and platoon-based coordination; the grant would cover $140,000, with a $45,000 local share.
Engineering noted grant spending cannot begin until July 1; early design and specification work will proceed before that date. The committee approved the three agreements by voice vote, 7–0; staff said the split applications were pursued to increase the chance of partial funding if not all projects are chosen by the state.
