GROSS: German Rail Open-Source SUMO Scenario
summary
GROSS is an open pipeline that combines OSM and GTFS to generate nation-scale SUMO rail scenarios, using topology-aware stop mapping with a hierarchical station model, station-level routing, validation and targeted repair. It cuts SUMO teleportation artefacts (reported reductions 1.6–11.5x across regions), produces a Germany scenario with 30,560 trips, and tightens delay distributions (median delays drop from ~42–88 minutes to below 10 minutes in many areas). Runtime for full-network generation falls from six days to about six hours.
