Zone-Based Automatic Speed Controller 🚗🛡️

An IoT-integrated embedded automotive safety platform designed to automatically govern public vehicle maximum velocities within sensitive geographic locations (e.g., schools, hospitals) through real-time geofenced coordinate calculation.

📌 Project Architecture

Operator failure to obey regional speed limitations represents a core component of vehicle accident rates. This system interfaces directly with the vehicle's electronic drivetrain controller to throttle velocity parameters autonomously based on precise physical coordinates, overriding operator acceleration requests when crossing a geofenced safety zone boundary.
