From Source to Product Signal

Test a Product Idea in Four Steps

The NTD monthly release reports service and unlinked passenger trips by transit agency and mode. Start with the adjusted monthly file and a few agencies. Values can be revised, reporting practices differ, and unlinked passenger trips count boardings rather than unique people.

1

Check the Setup

  • Python 3.10 or newer
  • A notebook environment such as Jupyter or Google Colab
  • The current Monthly Module Adjusted Data Release downloaded from FTA
2

Access the Data

  1. 1.Open NTD Data and download the current Complete Monthly Ridership workbook.
  2. 2.Save it as complete_monthly_ridership.xlsx and record the release date in the notebook.
  3. 3.Select a small agency set and compare like-for-like modes and metrics.

    "complete_monthly_ridership.xlsx",
    sheet_name="UPT",

Test a Useful Signal

Compare Monthly Transit Ridership Recovery

Compare reported passenger trips for two agencies with the same mode against the prior year.

  1. 01Record the file release and filter to two agencies and one common transit mode.
  2. 02Calculate year-over-year change for matched months and inspect missing or revised values.
  3. 03Explain why unlinked trips, reporting differences, revisions, and service changes limit comparisons.
