A transportation model is a computerized method of forecasting travel demand to predict changes in travel patterns and the utilization of the transportation system in response to changes in regional development, demographics, and transportation supply. The City uses the model to determine future transportation needs, impacts from proposed developments, and to review the effectiveness of proposed roadway improvements.
A traffic impact analysis is an engineering study to determine traffic volumes generation, vehicle distribution, and potential impacts on the existing transportation system from new development. New developments, or changes to an existing facility, typically require a TIA. This information is used to review what impacts and potential roadway system improvements that may be needed to mitigate the developments impacts.
A traffic impact analysis for a private development is required when there is a new facility or a change in an existing facility.
Most streets are constructed on land dedicated to the public, with is referred to a public right of way. This land varies in width but is under the jurisdiction of a public agency and is designated only for the placement of public improvements and access. The improvements typically include road section, sidewalk, storm drainage, and utilities.
