Advanced Driver Assistance Systems (ADAS)

Definition

Advanced Driver Assistance Systems (ADAS) are automated technologies designed to enhance vehicle safety and improve the driving experience by assisting drivers with various tasks. These systems use sensors, cameras, and algorithms to monitor the vehicle's surroundings, providing features such as lane departure warnings, adaptive cruise control, and automatic emergency braking. By integrating these technologies into different transportation modes, ADAS contributes to reducing accidents, improving traffic flow, and supporting the transition towards fully autonomous vehicles.

5 Must Know Facts For Your Next Test
