Smart Traffic Management System – Code Explanation
Introduction This project is a Smart Traffic Management System built using Python, Flask, OpenCV, SQLAlchemy, and multithreading. The system processes video feeds from multiple cameras, detects vehicle density, dynamically controls traffic signals, and logs traffic data into a database. Project Flow Video Input – Multiple cameras (or video files) provide live feeds. Processing – Each frame is analyzed using OpenCV to count vehicles. Signal Logic – Based on vehicle density, traffic lights are dynamically switched. Database Logging – Vehicle counts are stored every minute in SQLite. Web Dashboard – Flask renders live video, API endpoints, and a dashboard for monitoring. Code Explanation 1.
