• Traffic Impact Analysis (TIA) is a traffic engineering
  study which determines the potential traffic impacts
  of a proposed development.

• A TIA usually needs to be submitted by a developer
  before any changes in the land use zoning,
  subdivision maps, site plans or new driveways are

• A TIA should start in the earliest planning stages of a
  project including at site selection.

• Objective:
      • To establish a standardized process to serve as

        traffic impact assessments of urban and
        regional development projects.
