The City of Federal Way, Washington, is proactively addressing growing traffic congestion and preparing for the future of smart transportation. Through a partnership with Western Systems and Yunex Traffic, Federal Way deployed the proven Adaptive Traffic Control System—a global leader in congestion reduction and intelligent traffic management.
Challenge: Managing Growth, Congestion, and Mobility
Located in the heart of the Seattle-Tacoma metro area, Federal Way faces complex transportation challenges:
- Rapid population growth — nearly 100,000 residents
- Heavy commuter corridors connected to I-5 and State Route 18
- A growing need to balance vehicle flow, public transportation, and pedestrian safety
- Preparing infrastructure for major projects like the Federal Way Link Light Rail Extension and City Center Access Project
Federal Way needed a solution that reduced congestion in real time, optimized traffic flow, and supported scalable growth—all without costly infrastructure expansion.
Solution: Deploying Adaptive Traffic Control
Federal Way selected Western Systems to lead the implementation of Adaptive Control System—a globally proven technology deployed in over 125 cities.
Key Features of the Solution:
- Real-Time Adaptive Control: Constantly monitors traffic volumes and adjusts signal timing
- Public Transport Priority: Enables green waves for buses and reduces delays by up to 4 seconds per intersection
- Pedestrian Safety Enhancements: Uses intelligent detection to optimize crossing times without unnecessary vehicle delays
- Durable NEMA Cabinets: Custom-built to withstand the Pacific Northwest’s wet weather and seismic activity
- Data-Driven Operations: Provides robust traffic data for better planning and performance monitoring
This solution integrated seamlessly with Federal Way’s existing systems, supporting upcoming infrastructure expansions and improving the city’s overall mobility strategy.
Results: Measurable Improvements in Traffic Flow and Efficiency
Federal Way’s investment in Adaptive Traffic Control is expected to deliver results similar to nearby Seattle’s Mercer Corridor, where:
- Travel times reduced by 21% during peak hours
- Congestion and intersection delays drop
- Public transportation reliability improved
These early results highlight the power of adaptive traffic control as one of the most effective non-construction methods for congestion relief.
Community Benefits:
- Improved public transportation efficiency
- Safer pedestrian crossings with optimized signal phases
- Long-term cost savings from reduced maintenance and scalable technology
- Enhanced ability to manage growth and support future connected vehicle (CV2X) initiatives
Why Federal Way Chose This Path Forward
In selecting a partner to modernize its traffic operations, Federal Way prioritized professionalism, proven results, and a deep understanding of agency needs. They weren’t looking for generalists—they needed a team with a track record of delivering in the public sector.
The solution brought together local expertise and a platform that’s been tested and trusted in real-world deployments—both nationally and internationally. Designed for long-term performance, it reflects what’s possible when agencies collaborate with seasoned professionals who understand the full scope of transportation challenges.
With Western Systems’ close partnership model and Yunex Traffic’s globally proven technology, Federal Way moved forward confidently—investing in a system built not just for today, but for the evolving needs of tomorrow.
