Town updates adaptive traffic-signal system; staff recommends fiber, backups and continued tuning
Summary
Town staff reported the adaptive traffic-signal system (live since Nov. 2023) is reducing delays, lowering service calls and learning through firmware and detection tuning. Staff recommended leasing dark fiber (~$30,000/yr) for redundancy, adding battery backups to oldest cabinets and continuing outreach for event and school-bus issues.
Sean, a town transportation staff member, briefed the council on the town’s adaptive traffic-signal system and its performance since going live in November 2023. He said the system adjusts signal timing in near-real time and is designed to “maintain a consistent level of service through the corridor during peak hours and then again off peak.”
The town has begun measuring before-and-after travel times for eastbound lanes, and Sean said cumulative per-vehicle time savings (examples cited as reductions of 36 seconds on a peak run) add up across daily traffic volumes to deliver meaningful benefits. He told the council the system also includes bicycle and pedestrian detections so crosswalks are considered in the timing algorithm.
