RES2023-30: I-24 Smart Corridor

The I-24 SMART Corridor takes a comprehensive approach to improving the safety and travel time reliability along the corridor utilizing existing infrastructure and emerging technology. Vehicle-to-Everything (V2X) technologies are a key initiative of Tennessee Department of Transportation (TDOT) by aligning with several strategic goals of TDOT including safety, mobility, sustainability, and consistent customer experience. To achieve the benefits of successfully applied V2X technologies along the I-24 SMART Corridor, a clearly defined direction of V2X deployments needs to be established. The path towards applying V2X technologies throughout the I-24 SMART Corridor is described within the I-24 SMART Corridor V2X Roadmap. The I-24 SMART Corridor Roadmap provides an evaluation of the existing Intelligent Transportation Systems (ITS) infrastructure along the corridor as well as an implementation plan for V2X applications that meet the goals of the I-24 SMART Corridor. The initial deployment locations for V2X applications were based on several safety factors including existing traffic volumes, crash history, and reoccurring congestion. These safety factor hotspots led to the specific V2X application needs along the I-24 SMART Corridor. Along with the hotspots, geometric factors were included in determining which specific V2X applications were most applicable at each hotspot location. In addition to identifying and locating where specific V2X applications should be provided along the I-24 SMART Corridor, the Roadmap provides the costs associated with implementing these applications. These costs include software, physical integration, vehicular integration, and annual operations and maintenance costs.
