Oct 1, 2025Monthly work summary for 2025-10 focusing on MobilityData/mobility-feed-api: delivered GBFS Validator core feature and front-end UI with a header navigation, input for feed URLs and authentication, validation report display, and dynamic enablement via a remote config flag. Fixed GTFS Visualization Map undefined bounding box issue to prevent a white screen by stricter handling in CoveredAreaMap and GtfsVisualizationMap, ensuring maps render only with a valid bounding box. Performed a UX refresh and enhancement of the GTFS visualization map with route ID extraction, stop color expressions, new layer definitions for routes and stops, improved highlighting, a draggable panel for selected stops, and a scanning overlay for data loading. These efforts improved feed validation reliability, map rendering robustness, and data exploration UX, contributing to business value of faster validation, fewer incidents, and better data insights.
