New Traffic Signal Software

According to results released in January 2022 from the League City citizen satisfaction survey, traffic is one of the number one concerns for residents. In 2022, the League City Traffic Department launched a solution to ease congestion and improve mobility.

Traffic Lights: Intelligent Automation

Crews installed and activated specialized adaptive software at 16 intersections on FM 518 (corridor 1 on the map) between Maple Leaf and Iowa Avenue and began the installation of 20 additional intersections on east FM 518 and Marina Bay Drive (corridor 2 on the map). The Artificial Intelligence System behaves like a 24/7 traffic signal timing engineer and assesses real-time traffic flow and adjusts traffic signals to improve efficiency. The new software optimizes traffic signal timing on a daily basis and will adapt as the city grows.

The upgrades in corridor 1 in 2022 have helped improve traffic time along FM 518, particularly during TxDOT’s I-45 expansion project at the I-45/FM 518 intersection. The 20 additional signals for corridor 2 will be activated in 2023 and installation of corridor 3 will begin in 2023. The new software system is an important addition to League City’s long-term mobility plan. When fully implemented around the city, the movement of vehicular traffic will be the best it’s ever been along the city’s major corridors.

How It Works

Real-Time Traffic Signal Optimization

The system collects traffic data every second of the day. When it detects an abnormal traffic pattern (due to weather, an accident, large event, etc.) it will make real-time traffic light adjustments to improve flow and ease congestion.

Automated “Future-Proof” Signal Timing

As the system learns traffic patterns over time, it maximizes efficiency. Typically, a city will manually time and recalibrate their traffic lights every few years. Intelligent automation is “future proof,” meaning that it continuously learns and suggests better daily signal coordination timing.
