Plano is modernizing its traffic‑signal network to keep pace with rapid growth and to better serve residents, commuters and first‑responders. The city council approved an $8.5 million budget on June 8 for new vehicle‑detection equipment, upgraded controllers, and a fiber‑optic communications backbone. Senior Traffic Engineer Matt Tilke discussed how these upgrades will improve everyday travel and public safety.
Day‑to‑day work on the upgrade
Tilke said the city is in the middle of a major technology push. “We’re replacing all controllers, cabinets, and vehicle‑detection hardware at intersections, installing CCTV cameras, and upgrading the signal communication network to be almost 100 % city‑owned fiber optic. That supports really high bandwidth primarily so that we have good video coverage,” he explained.
How signals are timed
Plano runs four distinct timing plans: a morning plan, an afternoon plan, a midday plan, and a late‑evening/overnight plan. Controllers communicate with each other, allowing one intersection to inform another when traffic builds up, so signals can coordinate for smoother flow. All signals also feature emergency‑vehicle preemption; when an ambulance, fire truck or police cruiser approaches, the system grants a green light to expedite response.
Challenges from rapid growth
“Growth has definitely put a higher demand on our roadways,” Tilke noted. Many major intersections are at or beyond capacity, and added construction lane closures further reduce capacity. The new detection system is more accurate, providing real‑time traffic counts that enable the city to adjust signal timing quickly and reduce delays.
Criteria for new signals
When the Texas Department of Transportation (TxDOT) proposes a new traffic signal, it follows a set of engineering criteria. Planners examine traffic volumes, crash history, nearby schools, pedestrian activity and other factors. Traffic counts, delay studies and volume comparisons guide decisions. For example, if a neighborhood on Preston Road lacks convenient egress, that concern is factored into the design.
Benefits of the new detection system
The upgraded system streams video that is retained for 14 days. If a resident reports a problem at a specific location, staff can review the footage to verify the issue. The system also supplies continuous, real‑time traffic counts, replacing the older method of sending consultants to manually count vehicles for short periods. This richer data set allows planners to make adjustments for special events and to respond more effectively to emerging traffic patterns.
Looking ahead
Tilke emphasized that the technology upgrades are part of a broader effort to keep Plano’s transportation network reliable as the city expands. By leveraging fiber‑optic communications, advanced detection hardware and coordinated timing plans, Plano aims to reduce congestion, improve safety for motorists and pedestrians, and ensure emergency responders can navigate the city swiftly.
Residents can expect smoother commutes, quicker emergency response times, and a more transparent system for reporting and resolving traffic concerns.
