Sri Lanka Railways GPS Data Generator

This Node.js application simulates GPS data for 10 trains operating on 3 routes in Sri Lanka. It generates and transmits GPS data at one-minute intervals to the sri-lanka-railways-location-api, enabling real-time location tracking.

Features

• Simulate real-time GPS data for 10 trains across 3 major routes in Sri Lanka.
• Transmit GPS data to the backend API at one-minute intervals.
• Configurable transmission interval through environment variables.

Prerequisites

• Node.js (v14 or higher)
• npm (Node Package Manager)
• MongoDB (for train data storage)

2. Install dependencies:

   npm install

3. Set up environment variables:

   BACKEND_API_URL=http://localhost:5000/api/v1

   INTERVAL_MS=60000  # Interval for GPS data transmission (in milliseconds)

   MONGO_URI=mongodb://localhost:27017/railways  # Connection string for MongoDB

4. Start the application:
