College Bus Tracker Android App

College bus commuters live with uncertainty: the bus is "usually" at the stop by 7:45, except when it isn't, and nobody knows whether it already left or is stuck in traffic. Students either wait 20 minutes in the sun or miss the bus entirely. Transport offices, meanwhile, field the same "where is bus 4?" calls every morning. This project builds the student-facing tracker as an Android app: a route list with live status badges and ETAs, a live map per route showing the polyline, color-coded stops and a moving bus marker, and a stop timetable distinguishing passed stops, the next stop and scheduled times. A progress bar and ETA countdown translate raw position into "6 minutes to your stop". The demo drives the map with a simulated position feed so every screen — including the moving bus — works without hardware; the architecture is designed around a real GPS feed from a tracker unit on each bus, polled over a simple REST endpoint.

1. The app fetches the route list (routes, stops, schedules) and each bus's latest status from the tracker API (demo: local dataset).
2. Route cards render with live/scheduled badges and ETAs computed from the bus's current segment.
3. Opening a route draws the map: stop coordinates connected as a polyline, completed segments in the route color.
4. The bus marker position interpolates along the polyline from the latest GPS fix; a timer advances the demo feed.
5. Tapping the map opens the stop timetable: stops before the bus's position are marked passed, the nearest upcoming stop is "next".
6. The ETA countdown derives from remaining segments and the bus's recent pace; the progress bar shows trip completion.

Tech stack:

• Android (Kotlin) — native app target
• Canvas / map rendering (route polyline, markers)
• REST API design (bus positions, routes, schedules)
• GPS tracker hardware interface (production feed)
• Push notifications (delay alerts, planned)

• [Route list with live status] Each route card shows origin → campus, stop count, a LIVE or SCHEDULED badge, and the ETA or departure time.
• [Animated live map] The route polyline renders with stops; the bus marker moves along the route in real time, with completed segments highlighted.
• [Stop-wise timetable] Passed stops ticked green, the next stop highlighted, upcoming stops with scheduled times — the full trip at a glance.
• [ETA countdown] A big, glanceable "minutes to your stop" figure plus a progress bar, updated as the bus moves.
• [Trip info card] Departure and arrival times, driver name and bus registration number for each trip.
• [Delay awareness] When the bus is behind its scheduled pace, the ETA reflects it — no more "it should have been here" guessing.
• [Simulated GPS demo] The demo animates the bus along the route so the entire tracking UX is testable without tracker hardware.
