Speed Based Adaptive Lighting & Alert Technology for Vehicles

Today in India, we encounter numerous road accidents, resulting in permanent injuries for many individuals and fatalities for some. Major contributors to these accidents include inadequate lighting conditions, difficulty in assessing vehicle speed, and distractions from the high beam lights of approaching vehicles. Hence, it is essential to tackle this problem. This paper examines how vehicle safety is significantly affected by insufficient lighting and a lack of driver awareness regarding speed, frequently resulting in accidents due to traditional, fixed headlight brightness that cannot adapt to varying circumstances. The objective of this paper is to resolve these concerns by creating an innovative adaptive lighting and alert system aimed at improving vehicle safety during both daytime and nighttime. The system operates in two modes: manual and automatic. It employs a light-dependent resistor (LDR) to monitor the illumination from vehicles. The LDR gauges the intensity of oncoming vehicle lights, automatically adjusting the light intensity to an acceptable level. LEDs are utilized for headlamp lighting due to their effective illumination capabilities. By implementing different stages of headlamp illumination, it can minimize illumination waste and conserve battery charge.
