The RF-Based Automatic Vehicular Speed Limiting Control System in Critical Zones is an innovative approach to road safety, particularly designed to address the pressing issue of over-speeding in high-risk areas. These critical zones include locations such as school zones, hospital areas, pedestrian crossings, and accident-prone stretches of highways. Over-speeding in such areas is a significant cause of road accidents, and controlling vehicle speeds automatically can drastically reduce the risks associated with these zones. The core technology behind this system relies on Radio Frequency (RF) technology, which enables seamless communication between the infrastructure in the environment and the vehicles. RF transmitters are installed along critical road sections, continuously broadcasting signals. Vehicles equipped with RF receivers detect these signals as they enter the designated zones. The vehicle's system then identifies the unique frequency broadcasted by each zone, signaling the presence of a speed limit that needs to be adhered to.
