Connected Vehicle Technology Master Plan - Vision
Project Vision
Gwinnett County desires to set the standard for the application of connected
vehicle technology. Locally, the project will use the latest technological advances in
traffic management systems to improve traffic congestion and reduce crashes in
the Peachtree Industrial Boulevard Corridor. Beyond that, County leadership envisions that
this project will be the first of several and will have broad applicability in the Atlanta region
and across the country. The project will show how to set up a connected vehicle system,
including costs, benefits, applications, equipment, both hardware and software, and
personnel requirements. The project will help agencies charged with traffic safety
and mobility manage expectations, costs, and fully realize the benefits of
these new technologies.
