Some traffic studies say if drivers reacted half a second earlier, approximately half of all accidents could be avoided. Mobileye N.V. is among the suppliers attempting to provide alerts that let drivers know there's a situation that could lead to an accident. Its vision-based advanced driver assistance systems can be used in lane-departure warning systems, which are sometimes called a virtual rumble strip, that warns drivers when they're drifting from their lane. STMicroelectronics is providing system-on-chip technologies that add processing capabilities to the vision sensor. The EyeQ2 vision technology can also be used for adaptive headlight control, traffic sign recognition, forward-collision warning and collision avoidance through radar/camera fusion, which can drastically reduce the number of accidents.
