RideMate: Real-Time Transit & Ride-Sharing Platform

Overview

RideMate is a comprehensive, dual-mode transportation application built with React Native and a SQL Server-backed REST/WebSocket API. The system is designed to handle two distinct logistical domains simultaneously: an on-demand, in-city ride-sharing network (similar to Uber) and an inter-city transit booking system (bus ticketing).

The architecture features distinct interfaces with custom access privileges for riders and drivers, ensuring a streamlined and secure user experience across different user roles.

Core System Architecture

1. Real-Time Bidding & Negotiation Engine

• WebSocket Integration: Engineered a live pricing and negotiation system utilizing WebSockets for bidirectional, low-latency communication.
• Instant Fare Transactions: Enables riders and drivers to broadcast, receive, and accept live fare offers with minimal latency, instantly updating the application state across multiple clients.

2. Dual-Mode Transit Logic

• On-Demand Ride-Sharing: Integrates mapping APIs to handle dynamic pickup/drop-off routing, spatial querying for nearby drivers, and real-time location tracking.
• Inter-City Bus Ticketing: Features a structured booking pipeline for scheduled city-to-city transit, managing seat availability, scheduling databases, and ticket generation.

3. Relational Database Management

• SQL Server Infrastructure: Utilized SQL Server to handle highly relational data, ensuring ACID compliance for critical transactional data such as fare agreements, user balances, and booking histories.

Technical Stack

• Frontend: React Native (Cross-Platform iOS/Android)
• Backend Architecture: Node.js / Express.js (REST API)
• Real-Time Communication: WebSockets
• Database: SQL Server
• Integrations: Geolocation & Mapping APIs

Project Structure

• backend/: Contains the RESTful API routes, WebSocket server initialization, and SQL Server connection logic.
• frontend/: Contains the React Native client, state management, and UI components separated by user privileges (Driver/Rider workflows).

Local Setup & Initialization

(Ensure a local instance of SQL Server is running and Map API keys are configured in your environment variables).

Backend Setup:

cd backend
npm install
npm run start

Frontend Setup:

cd frontend
npm install
npx react-native run-android # or run-ios
