Performance Measures

  • FHWA program offices or "goal champions" determine performance measures
  • OHPI role is to help determine availability and suitability of existing data for use
  • Want to avoid multiple data collections of same data
  • Our emphasis is "collect once, use often"


Performance Measures

  • Highway-Related Fatalities per 100 Million VMT
  • Highway-Related Injuries per 100 Million VMT
  • % of VMT on NHS with IRI < 170
  • % of STRAHNET Miles with IRI < 170
  • Annual Hours of Delay
  • Congested Travel


Performance Measures
