Evaluation of Life Cycle Impacts of Intersection Control Type Selection

The methodology provided in this report provides guidance for North Carolina Department of Transportation (NCDOT) conversions of two‐way stop controlled intersections to other intersection types to enhance the effective allocation of public funds. The findings of this project have been incorporated into the study’s primary deliverable, the spreadsheet‐based NCDOT Intersection Life Cycle Cost Comparison Tool, which combines enhanced Highway Capacity Manual (HCM) 2010 methodologies and standard cost benefit analysis methodologies to calculate the long‐term net benefits of converting a two‐way stop controlled intersections to three different intersection options: 1) all‐way stop controlled, 2) signalized, and 3) roundabout types. This deliverable is designed for use during the planning phase of potential intersection conversion projects to help stakeholders identify the most cost‐effective conversion configuration option. This report summarizes the findings of all project tasks.
