Automatic Vehicle Speed Reduction System

This research project aims to automatically control vehicle speed in zones with speed limits, such as those designated for educational and medical purposes, in addition to occurrences of U-turns. In select regions, transmitters operating at a frequency of 433 MHz are strategically positioned. These transmitters emit an uninterrupted radio frequency (RF) signal. Once a vehicle encounters this radiation, its internal receiver becomes operational. As a vehicle traverses into a designated area, it receives a signal that governs its velocity. Consequently, the vehicle's speed is reduced to a predetermined level and remains at that value until it departs the area. Subsequently, the vehicle may resume acceleration autonomously
