Georgia DOT improved travel reliability for drivers through its $1.1 million Signal Priority Using Connected Intersections project. GDOT deployed connected vehicle infrastructure at over 800 signalized intersections using the 5.9 GHz band. Applications leveraging this infrastructure include transit and freight signal priority. Through V2X (or vehicle-to-everything) infrastructure, GDOT and its partners have created an interoperable regional deployment to provide a consistent, secure, equitable, and scalable interface between vehicles and infrastructure. One of those partnerships—with the Atlanta Transit Link Authority— saw GDOT pilot transit signal priority on Xpress buses on one of the Authority’s least-reliable corridors. Xpress route 431 runs weekdays between Stockbridge to downtown Atlanta. Hundreds utilize the route daily, even though it had terrible reliability due to congestion and navigation along busy city streets in Atlanta. By providing a more reliable trip time, transit riders on Xpress 431 ultimately reduce their travel time and can be more certain of arrival time at their destination.
