• 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.
