Abstract:This document serves as the final report on the construction and opening of the Roundabout Project in London, Kentucky (Kentucky Item Number 11‐904.1). This project (hereafter referred to as the London Roundabout) was constructed on the authority of the Kentucky Transportation Cabinet (KYTC), which received an Accelerated Innovation Deployment (AID) Demonstration grant of $1 million to offset project construction costs. The AID Demonstration program requires that award recipients submit a final report to the Federal Highway Administration (FHWA) within six months of project completion. The purpose of this report is to document the project delivery and construction processes, benefits, and lessons learned, which includes development and/or refinement of guidance, specifications, or other tools and methods that could be used to adopt the roundabout innovation as standard practice. At the beginning of the project, a Data Collection and Implementation (DC&I) plan was created to guide this study on the London Roundabout’s construction. The research team specified performance indicators and individual project goals to help work toward best practices and to measure the project's performance, with particular focus on the relevant outcomes that were achieved through the use of the innovation (i.e., the modern roundabout intersection).
