FREEVAL (FREeway EVALuation)

FREEVAL-PA is a freeway analysis tool developed by PennDOT. The computational engine is based on the Highway Capacity Manual and is intended to be utilized prior to the consideration of all maintenance, construction and permit planned projects on any Pennsylvania limited access highway. It can also be used prior to the determination for requiring any more advanced modeling or simulation.

FREEVAL-PA Provides:

  • A more detailed output than current spreadsheet and tools
  • A streamlined analysis process compared to simulation
  • Consistency in analysis across all Districts
  • Analysis support for lane reservation system
  • Numerous applications beyond work zone analysis
  • Rapid iteration of analysis for decision-support
