17.2.1 Reports

Reports are developed to support traffic and safety analysis assumptions, conclusions, and recommendations. Analysis reports typically include:
  • Traffic Analysis Report
    . The project traffic analysis report includes analysis assumptions and approach, data collection, analysis results, and recommendations. The traffic analysis report, at a minimum, includes content detailed in the outline in
    Appendix R, Section 1 – Traffic Analysis Report.
  • Safety Analysis Report
    . This report documents any safety analysis related to the study area, including data collection, approach, findings, and recommendations. The safety analysis report, at a minimum, includes content detailed in the outline in
    Appendix R, Section 2 – Safety Analysis Report.
  • Model Development Report.
     The model development report documents analysis performed on projects using microsimulation (microscopic) tools. The model report usually provides information on the model to review and verify accuracy when compared to real-world conditions. This report also includes assumptions, methodology, data collection, results, and any critical lessons learned and best practices to benefit future uses of the model. This report may include the calibration and validation process and consequential modifications to the base model. Changes to default values and parameters are supported by adequate justification, including supportive statistics comparing field measures and calibration parameters. The model development report, at a minimum, includes content detailed in the outline in
    Appendix N, Section 2 – Model Development Report.
     The report deliverable includes all scenario datasets, with sufficient information for TxDOT staff to replicate results. See
    Chapter 13
     for additional information on performing microsimulation (microscopic) traffic analysis. Users can coordinate with the TxDOT project manager to provide raw analysis files and data, if needed.
  • Traffic Impact Analysis (TIA) Report
    . This report introduces the existing conditions (e.g., project area, access management, existing conditions), outlines trip generation as derived from the latest version of the
    Institute of Transportation Engineers (ITE) Trip Generation Manual
    , describes the determination of trip distribution and trip assignment, summarizes future operations and LOS, and provides recommendations if mitigation measures are necessary. A recommended outline for the TIA report is found in
    Appendix Q, Section 2 – TIA Report Outline.
