• Abstract:
  Subsequent to the US DOT's 1995 "conditions and Performance" report to Congress, the HERS (Highway Economic Requirements System) model used by FHWA to evaluate national highway investment options was modified to incorporate both short run and long run demand elasticities. The model uses benefit-cost methods to evaluatate alternative improvements for sample projects. Demand elasticity in this evaluation allows estimated traffic volumes, as well as the location of the demand curve, to repond to endogenous factors -- such as travel time, operating costs, and accident rates -- that are affected by improvements. Typical improvements are additional lanes, lane or shoulder widening, realignment, resurfacing, and safety enhancements.
