Atlanta has become the first US city to establish a “Day One Deployment District” for cellular vehicle-to-everything (C-V2X) technology, marking a significant milestone in the country’s connected vehicle ecosystem.
The announcement was made during the ITS World Congress 2025 held in Atlanta last week, highlighting the Georgia Department of Transportation’s (GDOT) permanent enhancements to downtown Atlanta’s traffic infrastructure.
The deployment follows the 5GAA Vehicle-to-Infrastructure Communications Day One Deployment Guide, which set the standard for C-V2X roadside installations showcased at the event. 5GAA members played a crucial role in demonstrating real-world applications of the technology, emphasizing its readiness for wider adoption across other US cities and states.
This advancement is especially important given the high rates of vulnerable road user fatalities and the massive economic impact of traffic congestion, which costs the US economy over US$36bn annually. The estimated nationwide rollout cost for C-V2X technology is US$6.5bn, according to the ITS America National V2X Deployment Plan. The technology offers a promising solution to improve road safety and reduce congestion.
“Atlanta’s Day One Deployment District proves that C-V2X is ready for prime time. As the global cross-industry association for connected vehicle technologies, 5GAA has worked with its members, public agencies, and technology leaders to turn C-V2X deployment guides into reality. This milestone shows what’s possible when we align standards, infrastructure, and industry commitment,” said John F Kwant, executive director Americas, 5GAA.
Live demonstrations at ITS Congress illustrated the immediate benefits of C-V2X, including faster emergency response through traffic signal preemption, enhanced safety for pedestrians and cyclists, reduced local agency expenses, and streamlined tolling and parking via digital transactions.
The “Day One Deployment District” not only solidifies Atlanta’s leadership in connected transportation innovation but also opens new opportunities for revenue generation for local agencies and toll operators.
