RES2023-29: Connect and Automated Vehicle (CA) Readiness Plan

The Tennessee Department of Transportation (TDOT) desires an action plan for the implementation, operation, and maintenance of Connect and Automated Vehicles (CAV) technologies and use cases at traffic signals throughout Tennessee. The CAV Readiness Plan will impact how municipalities in Tennessee implement, operate, and maintain traffic signals. This research will build on previous efforts with a focus on research that can lead to actionable items. TDOT has deployed 132 DSCR units along SR 1 and another 30 units along I-24 within the Smart Corridor limits. TDOT vision is to develop an action plan describing the implementation, operation, and maintenance of CAV technologies and use cases at traffic signals throughout the state. The CAV Action Plan should also account for evaluating switching from DSRC to C-V2X and other anticipated industry changes as that will impact how municipalities implement, operate, and maintain their traffic signals. This project will build on previous I-24 Smart Corridor studies and condition assessments with a focus on research that can lead to actionable items.
