16.2.2 Preliminary Scoping

It is recommended that the specific project scope be confirmed with the local TxDOT District before the start of a TIA. Whether with an in-person meeting or alternate correspondence, discussing the scope with TxDOT will tailor a TIA to each specific project. TIAs can vary significantly from one to another, and consulting TxDOT is important to check that nothing is overlooked in a project.
This correspondence can help confirm:
  • Number of access points to TxDOT roadways;
  • Acceptable LOS thresholds;
  • Selected study years;
  • Anticipated influence area;
  • Intersections and roadways to be analyzed;
  • Scenarios to analyze;
  • Data collection method;
  • Project schedule and buildout year;
  • Data source;
  • Use of TDM outputs, growth factors, etc.; and
  • Other major projects in area
Once scope is confirmed with TxDOT, the TIA can be performed.
