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

Runs on EVERY listing row before any filtering: checks each project's Project Element / Mode classification against the 40 CFR exemption categories and regional-significance signals (EPMPO functional class is used directly for the RS test). Nothing is dropped here.

QA Findings

Each row is ONE inconsistency on one link in one year — a single project appears once per inconsistency, so a project with several rows has several separate things to look at.

QC — listed projects with a network year but no TDM tag

Every listing row whose Network year says it should be in the travel model but that no link carries as P1 or P2. 'Expected' rows are programmatic or transit projects that never tag roadway links.

About

Python Shiny implementation of the EPMPO TDM QA workflow (FY26). One network shapefile carries all six network years (2017–2052); the QA is year-based: network-year anomalies, unexplained lane drops, presence checks, and description-decoded lane comparison — plus the Section-3 / 40 CFR exemption QA check on the full listing.
