Future-Proofing Traffic Infrastructure in One of California’s Fastest-Growing Cities

Roseville, CA, is a city on the rise—young, innovative, and home to major employers like Kaiser Permanente. With a median age under 40 and a reputation for forward-thinking policy, it’s no surprise that the city is investing in resilient traffic infrastructure designed to keep up with its residents’ pace of life.

When outdated battery backup systems created vulnerabilities in Roseville’s intersections, Western Systems delivered a custom-fit cabinet solution that tripled power backup time, reduced maintenance demands, and provided remote diagnostics, all while supporting the city’s long-term goals around sustainability, safety, and innovation.

Outdated Systems in a Growing City

Roseville’s legacy traffic systems offered just 2–4 hours of battery life and were mounted on service pedestals incompatible with modern upgrades. During power outages, city staff had to manually inspect and test these units, often in dangerous conditions, just to keep intersections running.

With increased traffic flow, more emergency responders, and a tech-savvy population, the city couldn’t afford signal failures during storms, wildfires, or power grid disruptions.

A Custom Cabinet Built for the Future

Western Systems developed a modular cabinet solution tailored to the city’s existing infrastructure. It included:

  • Alpha Smart Inverters for automated alerts and remote visibility
  • Large battery arrays capable of powering signals for 10–12 hours
  • Seamless integration with existing ATC cabinets and service pedestals

This approach allowed the city to modernize without tearing out or replacing current assets—a cost-efficient and scalable strategy.

Impact: Benefits to Residents and City Operations

Public Safety

Intersections now stay operational longer, minimizing accidents and keeping pedestrians, drivers, and cyclists safe during emergencies.

Emergency Readiness

Reliable signals reduce delays for first responders and healthcare vehicles—critical in a city that’s home to multiple hospital campuses.

Smart City Efficiency

With remote monitoring, staff are no longer sent into the field to manually inspect battery levels, allowing teams to focus on priority tasks.

Sustainability

Batteries rated for 8-year life cycles mean fewer replacements, less waste, and more responsible infrastructure spending.
