RouteWorks
RouteWorks — Route Optimisation Platform
India's first online route-optimisation framework — demand in, publishable timetables out
RouteWorks turns travel demand into demand-aware routes and publishable timetables — one operator workflow from network ingestion to a schedule you can edit and ship. It optimises an existing GTFS network or designs new routes from scratch (GTFS optional, demand is enough), generating routes and timetabled trips for time-varying demand, all powered by Chartr's own foundational integer-programming solver.
Key Features
- ✓GTFS-native ingestion — or design from demand alone
- ✓Demand-aware routing that follows time-of-day OD flows
- ✓Column-generation optimisation solver built in-house
- ✓EPKM, fleet, capacity and budget targeting as tunable levers
- ✓Old-vs-new impact — quantify rider time and transfers saved
- ✓Editable Gantt timetables with zone clustering and AI flags
- ✓One-click, rider-ready GTFS export
Deployment Timeline
• Prebuilt optimised GTFS: instant
• New city from demand: 2–3 weeks
