Bus/Train Ticket Fare Calculator App

This project is an Android utility app for commuters that calculates the ticket fare between a selected boarding and destination stop on a local bus or train network, using a fare-table stored in a local SQLite/Room database seeded from public transit fare data.

Users pick their route, then their boarding and destination stop from a searchable list, and the app instantly displays the fare along with the number of stops and estimated travel time. A simple graph-based shortest-path calculation (Dijkstra's algorithm over the route network) suggests the best route when multiple lines connect the two stops.

A favourites feature lets frequent commuters save common routes for one-tap fare lookup, and the app works entirely offline once the route/fare data has been loaded, making it practical for daily use without needing constant connectivity.

Detailed Project Description

Bus/Train Ticket Fare Calculator App gives the user a focused everyday tool with a clean interface, local storage of their data and optional sync or reminders.

How It Works
1. The user enters or records data (amounts, steps, notes, recordings, values).
2. The app validates and stores it locally (SQLite/Room/SharedPreferences) or in the cloud.
3. Lists, totals, charts or conversions are computed and displayed instantly.
4. Reminders/notifications run in the background where the feature applies.

Technology Roles
- Android
- Java
- SQLite
- Room
- Dijkstra Algorithm

Implementation Steps
1. Sketch the screens and the data each screen needs.
2. Create the project in Android Studio, Room / SQLite and set up navigation between screens.
3. Define the local data model (SQLite/Room/SharedPreferences) or cloud sync.
4. Implement the core feature (tracking, conversion, recording, reminders, playback).
5. Add background work / notifications / permissions where required.
6. Test on real devices, handle edge cases and optimise battery and performance.
7. Generate the APK and prepare screenshots and documentation.

Key Features
- Simple, fast UI
- Offline storage
- Summaries and charts
- Notifications / sync where applicable

Expected Output
On completion the student will have an installable app that keeps the user's data organised and accessible.

Deliverables
