Swiss Transit Reachability

A browser-based map that uses GTFS timetables to calculate how far public transport can take you from any Swiss station.

ArcGISGTFSTypeScriptWeb Worker

Swiss GTFS files are transformed into optimized weekday, Saturday and Sunday indexes. A Web Worker runs a bounded Connection Scan Algorithm and calculates earliest arrivals without a remote routing service.

The interface combines an origin station, departure time, service pattern and a travel budget of up to five hours. ArcGIS displays reachable stops by travel-time bucket, with dark and light themes and an optional service area.

  • Nationwide reachability calculated directly in a Web Worker
  • 35,429 station groups and 2,880,665 connections in the weekday index
  • Scale-aware ArcGIS rendering keeps the map responsive with thousands of results
