Upload data

Upload the AAMPO submittal: the TDM shapefile bundle (one complete roadway-network shapefile for each of 2032, 2040, and 2050) and the Network Years project listing. A single ZIP containing the three year folders is preferred; the app preserves the year when their exported basenames are identical. Then click Process Data.

Exemption QA (pre-filter) — 40 CFR 93.126/.127/.128 + Section 3

Runs on EVERY listing row before the Exempt==Yes pre-filter: checks each project's exempt claim against the 40 CFR exemption categories and the regional-significance conditions in Section 3.3 of the AAMPO 2024 conformity determination. Nothing is dropped here — REVIEW verdicts need a reviewer decision before the lane QA results are trusted.

About

Python Shiny implementation of the AAMPO TDM QA workflow. Uses the FY26 shared audit library (apps/audit/lib/) through the AAMPO-specific adapter (apps/audit/lib/adapters/aampo.py) and folium renderer (apps/audit/lib/adapters/aampo_maps.py).

Next-conformity AAMPO structure:

  • One conformity network for 2032, 2040, and 2050.
  • DIR=0 links store a two-way LANES value; DIR=-1/1 links store one direction and are reconciled to the listing.
  • Year-specific total mainlane and frontage-lane values from the Network Years listing.
  • Compatible FTYPE families are grouped; incidental facility families sharing a tag are kept out of through-lane totals.
  • A row can match either the coded current cross-section or the documented LANES_BASE to LANES project change.
  • Explicit NB/SB/EB/WB widenings are checked per direction; workbook lane notes marked REVIEW stay manual-review items.
  • No separate NoBuild network is required because the master network carries *_BASE attributes.
  • AAMPO-specific description decoder for "Expand from X Lane Y to M Lane Z" phrasings.
