Logo for Connect, the department's newsletter

Instructions on how to complete TA001 “Request for Forecast Turning Movements” form

  1. The first section of the TA001 identifies the contact information for the parties submitting the forecast request (Project Manager, Transport Planner, Project Sponsor)
  2. The requestor shall fill out the “Study/Project description” and provide as much detail about the study/project and location as possible. Attach/upload documentation to identify specific location and size of any proposed development and specify the years for which forecast data is requested, i.e. 2021, 2026, 2031, and/or 2036.
  3. Please identify whether forecasts are needed for isolated intersection(s). If turning movement forecasts are required for specific times (am, pm, etc.), please indicate accordingly in the additional information section of this form (Question 11)
  4. Make sure the following documents are ready for upload:
    1. Map identifying project boundaries and specific intersections to be forecast (required)
    2. Project Brief or Project Definition Report (required)
    3. Proposed plans/drawings of intersections for future options (if applicable)
    4. Recent traffic count surveys (in the past two years)
  5. Provide an explanation of any other specific details that would assist with the completion of the forecast

To note:

  • Providing forecast tuning movements is subject to the receipt of the completed TA001 form;
  • Forecast turning movements are prepared based on DPTI’s strategic transport models which are based on a range of assumptions in accordance with the State’s strategic policies and plans;
  • These forecasts may need to be revised should these key assumptions change;
  • Forecast turning movements represent the average weekday, and
  • These forecasts are not to be used for any purpose other than that specified on the TA001 form.

Turnaround times

Generally, please allow a minimum of two weeks to complete turning movement forecasts.

Turnaround time for complex projects can be substantially longer. You will be contacted with an estimated turnaround time within a few days of receipt of the completed form.
