• Abstract:
  For many years there have been concerns that some traffic engineers may approach traffic impact studies with an eye
  
  toward assisting developers expedite their development approval rather than delivering an unbiased evaluation of the
  
  impact of the development on the surrounding traffic system. Without unbiased studies, agencies are not able to make wise
  
  decisions to preserve the capacity of the infrastructure. Alternately, some agencies may also misinterpret the data from
  
  traffic impact analyses, resulting in overcharging of developers by imposing requirements for transportation improvements
  
  and conditions that are simply not warranted.
  
  The goals of this research project were to examine decisions being made from traffic impact studies and to develop a set of
  
  best practices to supplement existing guidelines for developing and reviewing traffic impact studies. The research project
  
  selected and analyzed 12 case studies to compare post development traffic conditions to the traffic impact study forecasts
  
  of post implementation traffic conditions. Results of these comparisons were mixed. Best practices were identified for the
  
  following areas: land use code selection and application; pass-by trip reduction assumptions; seasonal variations;
  
  evaluation of other modes; analysis software; regional demand model verse growth rates; future year analysis; and safety.
