The rapidly advancing connected and automated vehicles (CAV) research is shifting the spotlight from ideation and innovation, toward implementation. The ubiquitous discussions on CAV are sharpening the focus at many agencies including the Florida Department of Transportation (FDOT), where the Transportation System Management and Operations program aims at developing a strong Florida Connected and Automated Vehicle initiative (Florida CAVI). A key element of the Florida-CAVI is its collaboration with the University of Florida to create a Test Bed called the ‘i-STREET.’ Among its initiatives is the ‘Gainesville Autonomous Transit Innovation Connector’ (GATrIC) project. GATrIC, the subject of this paper, presents the study-led conclusions for planning and deploying successful autonomous transit systems. Study aspects included crash data and traffic volumes; traffic characteristics; system elements including traffic signals, roundabouts, parallel parking, bike lanes, and bus stops; and operational, safety, and security factors. The lessons learned for the successful deployment of GATrIC and potential autonomous transit projects include: minimizing potential disruptions to the autonomous shuttle movement due to the pedestrian, bicycle and skateboard interactions; considering roadway geometry including roundabouts, intersections layout, on-street parking, and buffer lanes; modifying traffic signal phasing; developing detour options; and adjusting headway to minimize travel time. These conclusions also point to high positive impacts including the leveraging of such initiatives to invite industry for collaborating and testing emerging technologies, providing a proving ground for multimodal CAV safety enhancement opportunities such as passive pedestrian detection, utilizing data for internet of things and improved mobility, and institutionalizing a strong CAV practice.
