Council authorizes $133,188 for year‑5 traffic signal retiming work

The Tyler City Council on April 9 authorized the city manager to execute Work Order No. 4 with Kimberly Horne and Associates for $133,188 to perform Year 5 traffic signal timing improvements as part of the city's intelligent transportation system master plan.

Traffic Engineer Cameron Williams presented results from Year 4, reporting notable reductions in delays and stops and speed improvements on corridors including Gentry Parkway, Glenwood Boulevard and North Palace. Year 5 work focuses on retiming 12 intersections on the East Loop that have not been previously retimed and revisiting 14 intersections on South Broadway for updated traffic counts and optimization; together the effort covers about 26 intersections.

Williams said signal timing improvements rely on prior investments in communications, detection upgrades and intersection reconstruction; he noted coordinated timing cannot reach 100% of intersections because many are standalone (not part of coordinated systems). He described expected benefits as reduced delay and stops and presented benefit‑to‑cost ratios cited from past years ranging from about 28:1 up to 70:1 for signal timing work.

Councilmember Curtis moved to approve M1; the motion was seconded and carried on a voice vote. Staff will proceed to issue the work order and schedule counts and retiming work.

Williams said traffic controllers store timing plans and will revert to programmed timing after power interruptions; staff will compile before/after delay statistics and provide summarized results comparing current corridor delays with prior baseline data.
