Traditional speed limiters fail to address the complexities of modern roadways, necessitating innovative solutions to imbue speed control mechanisms with intelligence. This project aims to develop an intelligent GPS-based speed limiter system that dynamically adjusts speed limits, issues speed zone warnings, and automates speed reduction to enhance road safety. By integrating real-time GPS data with vehicle speed control mechanisms, the system accurately determines vehicle location, speed, direction, and road conditions. The project focuses on designing and analysing a system tailored for sedan cars that utilizes GPS technology for speed regulation. Equipped with a speed sensor, the system automatically reduces vehicle speed when it exceeds real-time GPS data speed limits. Visual and auditory alerts, such as a buzzer and LEDs, warn the driver, while an LCD screen displays speed ranges for improved user visibility and comprehension. The GPS module has an output of 9600 baud and can communicate with an Arduino board powered by a 5 V supply. It detects speed levels using a real-time GPS module, with a range of 111 km/h to 120 km/h for over speed, 101 km/h to 110 km/h for approaching speed, and 0 km/h to 100 km/h for appropriate speed. The LCD 20x4 displays current speed, with buzzers and LEDs indicating over speed, approaching speed limits, and appropriate speed. The nominal voltage for the DC motor is 12 VDC, and the speed works according to the switch. Overall, this project seeks to address the critical issue of inefficient speed control in modern transportation by creating an intelligent GPS-based speed limiter system, thereby fostering safer and more sustainable mobility for all.
