feat: gtfs feature tracker + updated header / footer section by Alessandro100 · Pull Request #128 · MobilityData/mobilitydatabase-web

Alessandro100 · 2026-04-27T13:46:47Z

Summary:

closes #127

Includes the GTFS Feature Tracker as well as a new header and footer section that has "Tools"

Expected behavior:

In the Feeds search page, when a user filters by "Feature" a button should display asking the user if they want to see the gtfs feature tracker.

The gtfs feature tracker page should include the same functionality as the demo provided in https://community.mobilitydata.org/gtfs-features

Bonus

When hovering on the feature, a "Feeds" item will appear which will bring the user to the feeds search page with that feature selected (See the important)

Testing tips:

Navigate to the gtfs feature tracking page and assure that the data is correct

Important
Some features names in the CSV do not match the names in the mobility database features

Fixed-Stops Demand Responsive Services -> needs to be -> Fixed-Stops Demand Responsive Transit
Zone-based Demand Responsive Services -> needs to be -> Zone-Based Demand Responsive Services
In-Station Traversal Time -> needs to be -> In-station Traversal Time
the naming is very sensitive to getting the data from the api

Fixed in commit ed6003e. The GTFS Feature Tracker button in the mobile drawer now uses component={LocaleLink} where LocaleLink is the Link from src/i18n/navigation, ensuring locale-prefixed client-side navigation (e.g. /fr/gtfs-feature-tracker on French pages) instead of a full-page reload to the default locale.

+export function formatDate(dateStr: string): string {
+  if (!dateStr) return '';
+  const d = new Date(dateStr);
+  if (isNaN(d.getTime())) return dateStr;
+  return d.toLocaleDateString('en-US', {
+    year: 'numeric',
+    month: 'short',
+    day: 'numeric',
+  });

[minor]: The informational link on the search page remains visible when the GTFS schedule is unselected from the filters. See attached video on how to reproduce it.
