• Abstract:
  The Intersection Life Cycle Cost Comparison Tool User Guide was developed as part of North ; Carolina Department of Transportation Research Project No. 2014‐11: Evaluation of Life Cycle ; Impacts of Intersection Control Type Selection. ; This spreadsheet‐based computational engine is designed to analyze the long‐term costs and ; benefits of NCDOT conversions of two‐way stop controlled intersections to other intersection ; types. It is designed to be used during the planning phase of potential intersection conversion ; projects to help stakeholders identify the most cost‐effective conversion configuration option.   ; This user‐friendly tool combines enhanced 2010 Highway Capacity Manual 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 alternatives: 1) all‐way ; stop controlled, 2) signalized, and 3) roundabout types. For the purpose of tool, a two‐way stop ; controlled (TWSC) intersection is defined as a four‐way intersection with no control mechanism ; for the main approach and stop signs positioned at the minor approach. ; Based on user inputs and standard state and national data, site‐specific construction and ; maintenance, user delay, and safety costs and benefits are calculated for each of the three ; conversion types. These costs and benefits are projected into the future using a methodology ; that considers the changing value of money over time. The resulting dollar figures can be ; compared to identify the intersection type that offers the greatest return on investment to ; North Carolina citizens over a user‐specified time period. ; Much of the material in this manual is in the accompanying instructional video at ; http://go.ncsu.edu/lcca_video.
