City of Goodyear, Arizona Building a Scalable Traffic Network for a Growing City
"When we set out to upgrade our traffic network, we were facing aging infrastructure and rapidly growing bandwidth demands. EtherWAN not only delivered a reliable technical solution, but their local support made all the difference. Being able to get someone on-site within hours is critical for a system that needs to operate in real time. This wasn't just a product deployment—it was the beginning of a long-term partnership. We trust EtherWAN's expertise and commitment, and we look forward to continuing our collaboration to build a smarter, more efficient transportation network for our city."
-- Hugh Bigalk, City Traffic Engineer, Goodyear, AZ
Background
Located in the Phoenix metropolitan area, Goodyear, Arizona is home to over 111,000 residents and growing rapidly. Its transportation system relies on a grid network anchored by two major corridors:
•Interstate 10 (east-west between Phoenix and Los Angeles)
•State Route 303 (north toward the North Valley)
The city manages 120 signalized intersections and nearly 800 connected devices, including traffic signals, cameras, and sensors. As Goodyear expands, so does the complexity of its traffic communications infrastructure.
The Challenge
When Goodyear began building its traffic network in 2008, the fiber backbone stretched only 3–4 miles and supported 15 intersections. Today, that number has grown nearly eightfold, creating new challenges:
•Bandwidth strain from modern CCTV & video detection systems
•Aging equipment limiting performance
•Need for scalability to support future growth
This increase is not only due to the number of devices but also the nature of the data being transmitted. Modern CCTV cameras and video detection systems generate significantly larger data packets than their predecessors, placing greater strain on the network. The city needed a robust, high-speed solution that could integrate with existing infrastructure and minimize downtime.
Solution
To address these challenges, the City of Goodyear partnered with EtherWAN and their partner, Clark Transportation, to modernize its' traffic communications infrastructure. The project required a solution that could seamlessly integrate with existing field equipment, including legacy switches, while delivering high-speed performance and scalability.
The City of Goodyear needed dependable local support for a traffic system that operates in real time. EtherWAN's ability to provide on-site assistance within hours helped ensure reliability throughout the upgrade process and beyond. This combination of responsive support and scalable technology enabled Goodyear to modernize its traffic communications infrastructure without interrupting daily operations. The solutions implemented included:
Product Highlights
•High-Speed Switching (EX78934E):
12-port 10GbE switch optimized for bandwidth-intensive applications like video surveillance and traffic data analytics.
•Seamless Integration:
Compatible with legacy field switches and existing infrastructure.
•Scalable Fiber Backbone
( EG97023, EG97244, IG5 Rack ) Expanded fiber network to support nearly 120 intersections.
•Local Technical Support
On-site assistance within hours, reducing troubleshooting time and improving system reliability.
Outcome
Today, Goodyear's Traffic Management Center oversees 116 signalized intersections through a robust, scalable network. With EtherWAN's equipment and local support, the city is positioned to:
• Handle growing bandwidth demands
• Reduce downtime with rapid on-site service
• Support future smart city initiatives
The partnership between Goodyear, Clark Transportation, and EtherWAN has delivered a resilient, future-ready traffic communications system that ensures safe, efficient mobility for residents. .
