sleep deprivation is a condition of not having enough sleep it can be either chronic or acute. a chronic sleep-restricted state can cause fatigue. fatigue is a subjective state related to sleep deprivation, the more someone is deprived of sleep the more likely that person is to be fatigued. several studies indicated that drowsiness/fatigue can affect steering performance and speed control. rese...

background the most accidents can be directly attributed to human factors. hence, more traffic crashes result from driver malfunctioning which from among them, the driver behavior is a proximal factor in the road traffic injuries causation chain. objectives this study aims to investigate relationship between aberrant driving behaviors questionnaire (dbq factors) and self-report crashes involvem...

background: we determined the levels of subjective and observer drowsiness and facial dynamics changes. methods: this experimental study was done in the virtual reality laboratory of khaje-nasir toosi university of technology in 2015. facial dynamics changes like changes in eyes, mouth and eyebrows were surveyed on twenty-five drivers in 2015bykss (karolinska sleepiness scale) and ord (observer...

music has been used as mood modulator by humans for many years. nowadays music is mostly play as one of the switch in a car. although music listening is common at during driving. its impact on driving performance has developed debates and controversies. studies have shown that self-selected in-car music listening can improve driver’s mood and behavior. however other studies have reported that b...

driver fatigue may impose the risk of crashes and is a leading cause of death in transportation industry. this study aimed to detect driver cognitive fatigue based on changes in eeg frequency bands in non-professional drivers during a simulated driving task. in a descriptive-analytical study, 12 healthy male car drivers took part in a two hour driving session on a simulated monotonous road, whi...

In this paper a robust road departure avoidance system based on a closed-loop driver decision estimator (DDE) is presented. The main idea is that of incorporating the driver intent in the control of the vehicle. The driver decision estimator computes the vehicle look ahead lateral position based on the driver input and uses this position to establish the risk of road departure. To induce a risk...

The present study proposes a decision-making model based on different models of driver behavior, aiming to ensure integration between road safety and crash reduction an examination speed limitations under weather conditions. investigated differences in attitude, conditions I-69 Flint, Genesee County, Michigan, using the fuzzy logic approach. A questionnaire-based survey was conducted among samp...

In this article, a mathematical model was developed to influence the intensity of steering wheel turn by driver on vehicle's stability. Comparison with experiment results made it possible establish their adequacy. The effect three conditional drivers examined. When performing 'J-turn' maneuver, comparing indices 1st, 2nd and 3rd drivers, proximity requirements standard established. It found tha...
