Non-standard safety technology

This paper explains the nonstandard safety technology which assists drivers to enhance drive safely when the driver is physiologically impaired, for example, drunk, fatigued, irritable, asleep, etc. When a driver operates a vehicle with some actions which may not result in an accident immediately but may reveal that the driver is drunk, fatigued, or asleep, the non-standard safety enhancement system makes a decision from the actions to determine whether the driver is physiologically impaired based on the available information of vehicle, road, and others before the driver causes an accident.
