Contribute to Transitous: An Open Source Public Transit Routing Service

Transitous, a community-run public transport routing service built on the MOTIS engine and thousands of global datasets, powers features in apps like GNOME Maps. This post details how to contribute data improvements: First, verify Transitous data against reality; then, learn how to add and improve GTFS static data, GTFS Realtime data (including trip updates, service alerts, and vehicle positions), GBFS shared mobility data, and GTFS-Flex on-demand service data. Finally, it encourages contributions to OpenStreetMap data, particularly indoor floor level information. Transitous welcomes contributions of all kinds, whether code, data, math, transportation expertise, or IT operations.
