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 Real time development 32-bit CPU’s which are widely used satisfies high speed processing, but they need a platform which makes it to run systems steadily and speedily. Stability and security plays an important role in embedded field. Based on the price, architecture and security Linux is one platform which plays an important role in embedded applications .The new version kernel has more bene...

BACKGROUND Given the long hours on the road involving multiple and interacting work stressors (i.e., delivery pressures, irregular shifts, ergonomic hazards), commercial drivers face a plethora of health and safety risks. Researchers goal was to determine whether and to what extent long-haul trucker work schedules influence sleep duration and quality. METHODS Survey and biometric data collect...

FOREWORD A laboratory study was conducted to examine the duration of the restart period for commercial motor vehicle drivers that would be needed to recycle to the work force with optimal performance. This report presents the design, methods, research findings, and conclusions of the study. This report may be of interest to anyone interested in fatigue and its management in commercial motor veh...

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...

This report describes development of technologies that can assist a driver with safe lanekeeping in the event that the driver is incapacitated due to fatigue. We use a Differential GPS system to sense the position and velocity of the vehicle since it appears that this method offers adequate precision with a low enough infrastructure cost to make the system practical in most rural settings. We h...

Following the success of the Victorian Activity & Travel Survey (VATS) of household travel, the Transport Research Centre (TRC) initiated a Freight Activity & Commercial Travel Survey (FACTS) to provide a much needed database of freight-related information for the Melbourne metropolitan area. The objective is to provide detailed, accurate and current data on freight travel and commercial activi...

Considerable progress has been made in measuring drowsiness and understanding its effects upon human performance in the laboratory and in simulated and operational driving conditions. This work builds upon previous research and identifies an appropriate design for a drowsy driver detection interface. A participatory design process was used that included both design experts and drivers in separa...
