Traffic Impact Analysis Process

Traffic Impact Analysis (TIA) studies are intended to determine the need for any improvements to the adjacent and nearby transportation system in order to maintain a satisfactory level of service, an acceptable level of safety and the appropriate access provisions for a proposed development. The review process ensures the following: an open discussion between the city and developer regarding traffic aspects of site development; fair assessment of impacts and need for improvements; and an awareness of other developments under construction, pending, or anticipated. TIA Worksheets and Reports should be prepared under the supervision of a qualified and experienced transportation professional who has specific training in traffic engineering and several years of experience related to preparing transportation studies. TIA Reports shall be signed and sealed by a registered professional engineer.
