Multimodal journey planning and commuter alarm system.

IXIT connects a work start time, personal preparation, a journey and a buffer into an understandable commuter timeline. It combines an Android interface, local data modelling, GTFS preprocessing and custom routing logic.

Current capabilities

A data and routing system behind an understandable commuter plan.

Shared transit data model

GTFS preprocessing produces a shared data model for stop search, route selection and commuter planning.

Custom multimodal routing

Routing supports direct journeys and journeys with up to six transfers, including walking and transfer relationships between stop areas.

Search and timeline

SQLite stop search operates in the millisecond range. A commuter timeline derives walking, departure, arrival, leaving and wake-up times.

Android integration and tests

Alarm and notification integration are backed by unit tests for routing and search logic.

Data foundation

Prepared for real routing workloads.

The Germany-Switzerland dataset currently contains approximately 3.43 million trips and 61.9 million stop times. More than 2,500 cross-source stop identities have been matched to support station families, aliases and transfers.

The original source data remains separate from later application-oriented transformations.

Public demo boundaries

Real planning logic, deliberately limited inputs.

The public web demo uses prepared scenarios and a controlled timetable snapshot. Free address search, real-time information and the actual Android alarm are not available in the browser demo.
