Advanced driver-assistance systems (ADAS), are technological features that are designed to improve driver safety and prevent automotive accidents. ADAS utilizes sensors such as radar, sonar, lidar and cameras to perceive the world around the vehicle, and either provide critical information to the driver or take automatic action to avoid or mitigate the effects of a crash.

ADAS systems are designed to increase driver safety and decrease the number and/or the severity of automotive accidents. According to a study conducted by AAA foundation, ADAS has the potential to prevent 40% of all vehicle crashes, 37% of injuries and 29% of vehicular deaths.
