Artificial Intelligence Techniques for Driver Fatigue Detection
… Convolutional Neural Networks models to detect driver distraction and fatigue using driver facial expressions. The proposed model provides high accuracy during both training and validation. The research was inspired to contribute to transport safety by providing alternative solutions to detect …

Analysis and detection of driver fatigue caused by sleep deprivation
… devise a systematic way to infer the state of driver alertness based on driver-vehicle data. Although sleep and fatigue are major causes of impaired driving, neither effective regulations nor acceptable countermeasures are available yet. The first part of this thesis analyzes driver-vehicle …

The Impact of Local/Short Haul Operations on Driver Fatigue
… conducted a series of focus groups in which L/SH drivers provided their perspective on safety issues, including fatigue, in their industry. As a follow-up to the Hanowski et al. work, the effort presented here consisted of an on-road field study where L/SH trucks were instrumented with data …

Field Study to Evaluate Driver Fatigue Performance in Air-Inflated Truck Seats
… the relationship between vehicle seat design and driver fatigue, improve two newly proposed objective methods for evaluating driver fatigue, and provide design guidelines for evaluating and improving vehicle seat characteristics in terms of driver fatigue. Each driver completed a test session on …

An On-Road Investigation of Commercial Motor Vehicle Operators and Self-Rating of Alertness and Temporal Separation as Indicators of Driver Fatigue
… data collection system capable of evaluating driver performance in an extended duration real-world commercial motor vehicle environment. The complexities associated with the development of the system, both technological and logistical and the necessary modifications to the plan of research are …

Dynamic Modeling and Control of a Car-Like Robot
… of such systems could conceivably reduce driver fatigue by removing nearly all the burden of the driving process from the driver while on the highway. System dynamics of car-like robots with nonholonomic constraints were employed in this research to create a controller for an autonomous …

Automatic Ultrasonic Headway Control for a Scaled Robotic Car
… an active area of research for some time. Human drivers exhibit slower response times and errors in judgment that can have serious adverse affects on traffic flow. These types of errors can be reduced or eliminated from the driving experience by introducing computer control systems into the …

Speed and fatigue control using speed limiter integrated fatigue analyzer for truck and bus
… factors such as external (34%), attitude (24%), fatigue (20%), over speed (17%) and vehicle technical problem such as maintenance short falls (5%). The main objective of this study is to develop the speed limiter that integrated with fatigue analyser and investigate its effect on engine …

Assessing the Effects of Driving Inattention on Relative Crash Risk
While driver distraction has been extensively studied in laboratory and empirical field studies, the prevalence of driver distraction on our nation's highways and the relative crash risk is unknown. It has recently become technologically feasible to conduct unobtrusive large-scale naturalistic …

The Impact of Sleepiness and Sleep Constructs on Driving Performance
… driving performance. The correlation between a driver's perception of their sleepiness and their driving performance is also unclear. The primary goal of this study was to create an in-depth model demonstrating which measures of sleepiness influence driving performance. It was hypothesized that …
