Abstract: Road traffic accidents continue to be a leading cause of fatalities worldwide, with human error contributing to nearly 90% of incidents. Advanced Driver Assistance Systems (ADAS), particularly Automatic Emergency Braking (AEB), have significantly improved vehicle safety but remain expensive for widespread adoption in developing regions. This paper presents the design and development of a low-cost Intelligent Automatic Braking System (ABS) using ultrasonic sensing and embedded control. The system employs real-time distance measurement and a threshold-based decision algorithm implemented on an Arduino platform. A multi-stage braking strategy is introduced to enhance safety and comfort. The proposed system is evaluated through experimental testing and compared with existing AEB and Automatic Preventive Braking (APB) approaches. Results demonstrate a response time below 50 ms and reliable obstacle detection, making the system suitable for low-speed urban applications.
