This paper presents a safety-oriented system designed specifically for accident prevention in ghat (hilly) road sections. The primary objective of the proposed system is to reduce accidents caused by limited visibility on sharp curves and narrow roads, where drivers are unable to detect oncoming vehicles from the opposite direction. High vehicle speed and lack of real-time information further increase the risk of collisions in such regions. To address these challenges, an embedded system based on the ATmega328 (or 8051) microcontroller is proposed. The system integrates multiple sensors, including IR or ultrasonic sensors for vehicle detection and a piezoelectric sensor for landslide detection. Additional components such as LED indicators, an LCD display, a GSM module, and a buzzer are incorporated for alert generation and communication. When a vehicle is detected at one end of the road, the system activates a warning signal using a flashing red light and alerts drivers, while a green signal indicates that the road is clear. In the event of a landslide, the system automatically triggers an early warning mechanism and closes safety gates to prevent vehicle movement, thereby reducing the risk of accidents. The proposed solution aims to enhance road safety and provide a reliable, real-time alert system for hilly terrains.
