An open data portal serves as the central hub where citizens, researchers, and analysts can discover, explore, and download structured data. Rather than relying on proprietary cloud platforms with opaque pricing, self-hosting an open data portal gives you complete control over data governance, access policies, and infrastructure costs.</p> https://www.pistack.xyz/posts/2026-06-08-self-hosted-public-transit-data-servers-onebusaway-opentripplanner/ Mon, 08 Jun 2026 00:00:00 +0000 https://www.pistack.xyz/posts/2026-06-08-self-hosted-public-transit-data-servers-onebusaway-opentripplanner/ <p>Public transit agencies around the world publish their schedule and real-time data using the General Transit Feed Specification (GTFS).
