Chichi Bus

Crowdsourced JUTC bus tracker · Live

  • All 159 JUTC routes and 208 stops, scraped from the official route guide
  • Routes snapped to real roads with OSRM, using a dynamic-programming pass to avoid U-turn loops
  • Location is only sent when you confirm; live sharing is a separate opt-in
  • Offline-ready PWA with precached route data
