The City of Roswell is implementing a citywide traffic preemption system that will allow emergency vehicles—such as fire trucks and ambulances—to safely and more efficiently navigate intersections while en route to emergencies.
Using cutting-edge technology called Glance Priority and Preemption, emergency vehicles will now be able to communicate directly with traffic signals. When a vehicle equipped with the system approaches an intersection, the signal will automatically switch to green, while opposing traffic is brought safely to a halt.
This system, developed and manufactured locally in Alpharetta, uses a combination of GPS, cellular, and radio technologies to ensure reliable performance—even in complex environments like tunnels and overpasses.
“Seconds matter when lives are at stake. This technology not only helps us reach residents in need more quickly, but it also makes the roads safer for everyone,” said Mayor Kurt Wilson. “Installing technology like this reinforces our commitment to building a high-performing, responsive city that delivers on its mission to provide an exceptional quality of life.”
Benefits of the new system include:
- Improved Response Times: Adaptive signal changes can reduce emergency response times by up to 20%.
- Increased Safety: Intersections are one of the most dangerous places for emergency responders. Preemptive signaling significantly reduces the risk of crashes.
- Enhanced Reliability: Unlike older systems that required line-of-sight, the new GPS-based system works in all conditions and communicates in real time with Roswell’s traffic control infrastructure.
- ISO Score Benefits: Faster response times may improve the City’s Insurance Services Office (ISO) rating, potentially lowering home insurance premiums for residents.
Installation of the technology is currently underway and will continue across all 107 signalized intersections in Roswell, with completion of the project expected late summer/early fall 2025.
The total cost of this project is $773,714. The majority of the funding ($487,802) comes from voter-approved Bond funds and the remaining costs ($285,912 ) are covered by the City of Roswell’s General Fund.
