Advanced driver assistance systems are designed to increase car safety and road safety overall. They help the driver in the driving process to enable safe and relaxed driving. Some examples of driver assistance systems that maximize safety include antilock braking systems, adaptive cruise control, blind spot detection, driver drowsiness detection, electronic stability control, emergency braking systems, hill descent control, intelligent speed assistance, lane departure warning systems, pedestrian detection, rear cross traffic alert, and traffic sign recognition. These systems alert drivers to hazards, help maintain safe distances and speeds, and in some cases automatically apply brakes to avoid collisions.
