Oct 1, 2024In October 2024, BayAreaMetro/NetworkWrangler delivered repository-based GTFS data sourcing and enhanced data source documentation. The GTFS data source now uses a repository-relative path, enabling sourcing directly from the project and reducing reliance on a shared network drive. Documentation and data-source handling were clarified for transit updates, including current data sources, Asana task references, and notes on the Treasure Island Ferry data. These changes improve maintainability, reduce data-ops friction, and support faster iteration on transit data updates. The commits reflect focused code and doc improvements (d3bdecfc220346e45f901ec824815f61d95ecf5d; 560fcf9d39a83bc657d1bceaf59956a80a84d531; aa1e630996d8a6db977580abe382a078c6e69553).
