Abstract

Driver drowsiness, or getting sleepy while driving, Causes many road accidents every year. To keep road Safe, this paper reviews different way to detect when a driver is getting tired. Two main methods are studied Radar-based systems and Camera –based systems.

Radar can check heart rate and breathing by sensing small Chest movements without touching the driver. Camera systems watch  the driver’s face and head to see if the eyes are closing or the head is dropping. Using both methods together can give a more complete view of the driver’s condition. Studied show radar works well even in low light, and cameras can clearly spot visible signs of tiredness.
