Bus Navigation System: A GPS and Real-Time Transit Route Guidance Framework

This paper presented a proposed bus navigation system that integrates static transit information, geographic positioning, route computation, and real-time transit updates. The architecture separates data management, route planning, ETA estimation, and passenger guidance so that the system can begin with timetable-based information and progressively adopt real-time capabilities. Standardized transit representations such as GTFS and GTFS Realtime provide a practical foundation for interoperable transit applications. The proposed evaluation methodology emphasizes measurable route quality, ETA accuracy, response time, and robustness under incomplete data. A future implementation and field evaluation can validate the framework using real busnetwork and vehicle-tracking data.
