RFID which detects the icons beside the road Automatic speed regulation of vehicles based on speed zones using RF technology

Automatic Speed Regulation of Vehicles Based on Speed Zones Using RF Technology is an intelligent transportation system designed to improve road safety by automatically controlling vehicle speed in designated zones. The system utilizes Arduino as the main controller, RFID reader for location identification, RFID tags representing different speed zones, LCD display for status monitoring, and DC motors controlled through a motor driver to simulate vehicle movement. Each RFID tag corresponds to a specific location such as school zones, hospital zones, residential areas, and highway sections, with predefined speed limits. When the vehicle enters a particular zone and the RFID reader detects the corresponding RFID tag, the Arduino automatically adjusts the motor speed according to the permitted speed limit of that location. The LCD continuously displays the current zone and speed information. This system reduces driver negligence, enhances road safety, and supports intelligent traffic management.
