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.
