Fatigue at the wheel has been strongly related to car accidents. Traditionally, this phenomenon has been studied in laboratory conditions by means of performance testing. Here, we aimed to improve road safety assessing driver fatigue at the wheel in real scenarios. For this purpose, we have built BioTracker R ©: a flexible non invasive platform. A smartphone and a microcontroller unit are the c...

According to Dr Ebrahim, some 6 percent of all crashes in the United States can be attributed to a lack of sleep. Some 20 percent of accidents in the United Kingdom are attributed to fatigue and one third of accidents in Australia are attributed to sleep-related ailments. A 1996 French study found that more than two thirds of road accidents were caused by two factors: excessive speed and driver...

Drowsiness and fatigue are serious problems in all transportation systems. One persistent issue is the lack of an agreed definition of these respective energetic states. Here we review the theoretical approaches (cognitive versus physiological) framing the driver fatigue problem. Known contributing factors to drowsiness include sleep debt, circadian rhythm, and shift work. However, we also sugg...

Driving fatigue is more likely to bring serious safety trouble to traffic. Therefore, accurately and rapidly detecting driving fatigue state and alleviating fatigue are particularly important. In the present work, the electrical stimulation method stimulating the Láogóng point (PC8) of human body is proposed, which is used to alleviate the mental fatigue of drivers. The wavelet packet decomposi...

This paper describes an in-vehicle non-intrusive biopotential measurement system for driver health monitoring and fatigue detection. Previous research has found that the physiological signals including eye features, Electrocardiography (ECG), and their secondary parameters such as HR and HRV are good indicators of health state as well as driver fatigue. A conventional bio-potential measurement ...

Strategies to achieve ambitious targets for reducing road accidents ( 34 ) have largely focused on engineering and technological advancements, the modification of occupational demands, and, to a lesser extent, human factors. These factors include stress and psychological states; sleep, fatigue, and alertness; and health status. Physical activity appears to influence all these human factors but ...

One of the most important problems to solve is eye location for a driver fatigue monitoring system. This paper presents an efficient method to achieve fast and accurate eye location in grey level images obtained in the real-word driving conditions. The structure of eye region is used as a robust cue to find possible eye pairs. Candidates of eye pair at different scales are selected by finding r...

In the present trend suggestsdriving and navigation support systems are getting importance because it is crucial in supporting drivers in several conditions in automobile industry. It is important for driving support systems to detect the status/activity of driver’s consciousness. Detecting onset of driver fatigue could prevent the accidents caused by drowsy driving. It is proposed to detect / ...

We have performed a pilot study to assess obstructive sleep apnea (OSA), work and life-style factors as causes of driver fatigue in transport drivers. This study is part of a larger national study of sleep disordered breathing in transport drivers. A group of NSW transport drivers completed a survey designed to assess an individual's level of daytime sleepiness and their likelihood of having OS...
