Kentucky Transportation Center Research Report
Executive Summary
The Kentucky Transportation Cabinet (KYTC) has adopted a data-driven decision-making process to allocate funds for highway improvement projects. This process — Strategic Highway Investment Formula for Tomorrow (SHIFT) — requires that candidate projects be scored on five critical metrics: safety, asset management, congestion, economic growth, and benefit/cost analysis. The congestion metric is vehicle hours of delay (VHD), which was first developed for the SHIFT 2020 cycle (1). For SHIFT 2022, VHD is estimated using probe speed data acquired for 166,527 directional miles of Kentucky highways.
This report summarizes analyses performed using 2018-2019 HERE speed data, and …
