Signal retiming on FM 1472 cut southbound PM travel times nearly in half, consultant says
Summary
A traffic-signal timing optimization for 16 intersections along FM 1472 produced measurable travel-time reductions in field tests. Consultants reported modest AM improvements and substantial PM reductions after field tuning; they recommended further operational and geometric studies to add capacity where needed.
LAREDO, May 21 — A traffic-signal timing optimization on FM 1472 that covered 16 intersections from Fletcher Lane to FM 3338 reduced corridor travel times in field testing, according to consultant ATG DCCM.
Jeff Schick of ATG presented the results after TxDOT and city crews implemented new timing plans and performed field fine-tuning in March. The study grouped intersections into three timing groups and set common cycle lengths to improve coordination.
Why it matters: FM 1472 carries heavy truck and commuter traffic and has long delays at closely spaced signals near the I-69 interchange. Signal timing cannot substitute for additional…
