This document summarizes a student project to develop a public bus tracking system using mobile phones rather than dedicated hardware. The system would use the GPS and GSM capabilities of conductor smartphones to track bus locations in real-time and display them to users via an app. When a user searches for a bus, the system would provide the bus's current position on a map and estimate time of arrival at stops. This low-cost, software-based approach aims to address issues of unreliable bus schedules by allowing users to see bus delays or diversions in real-time.
