• Abstract:
  The I-24 Smart Corridor project, launched by TDOT since 2018, is a first-ever Smart Corridor study in Tennessee. This project integrates I-24 and SR-1, a parallel arterial roadway, with physical, technological, and operational enhancements to provide road users with accurate, real-time information and actively manage traffic. The I-24 project is conducted via three phases. At the time of this report, Phases 1 and 2 are complete, while Phase 3, targeted at long-term development, is still under design and deployment. This research project aligns with the project’s overarching goals, to assess the impacts of multiple strategies implemented during Phases 1 and 2, with particular emphasis on travel time reliability, safety, and mobility. Through comprehensive before and after evaluations and benefit cost analyses, this effort also aims to provide a data-driven foundation for future investments in Smart Corridor initiatives across Tennessee.
