The American Association of State Highway and Transportation Officials (AASHTO) SPaT was created to challenge state and local public sector transportation Infrastructure Owners and Operators (IOOs) to deploy DSRC infrastructure with SPaT (and MAP) broadcasts in at least one corridor or network (approximately 20 signalized intersections) in each state by January 2020.
As of January 2020, GDOT had 410 Roadside Units (RSUs) in operation with connectivity on every major arterial in metro Atlanta.
