Automotive research and technological development to date have enabled improvement in driving comfort, operational efficiency, motion stability and, most importantly, safety. An expectation for perfect or near-perfect vehicle system automation is increasing. However, the actual application of high-level technologies becomes more challenging as more advanced and complex technologies develop because the roadways in real life are comprised of countless uncertainties. The coexistence of automated vehicles and human-driven vehicles on roadways will be inevitable and drivers exhibit diversified driving habits and decision-making idiosyncrasies, behaving differently even in the same situation. As such, an appropriate understanding of human driver behavior in various driving situations would be beneficial. This dissertation is motivated by a research assumption that people’s driving behavior, even in crash imminent situations, can be predicted by analyzing a wide spectrum of daily driving data which also can be utilized in designing personalized control systems especially in crash imminent situations. This dissertation presents several applications of advanced control theories to replicate and to predict drivers’ longitudinal (i.e. speed control) and lateral (i.e. steering wheel control) control behaviors in various driving situations by utilizing the respective drivers’ historic driving data. In addition, optimally personalized control systems based on personalized situational evaluations in crash imminent situations are presented. Three test vehicles and a virtual reality driving simulator were used to collect driving data. In addition, extensive naturalistic driving data which include several crash and near-crash events were used for identifying driver characteristics. The simulation results showed that the proposed models are able to replicate driving data and predict individual driver’s preferred control inputs, and successfully control a vehicle that adapts to individual drivers in crash imminent situations. The contributions of this dissertation include: 1) an analysis of human driver behavior in various driving situations for driving characteristic identification; 2) development of a prediction model which is able to provide driver’s preferred control inputs; 3) development of a personalized crash-imminence detection model based on drivers’ historic driving data; 4) applications of control theories to develop optimally personalized control models in crash imminent situations; and 5) development of various metrics to evaluate driving situations for personalized decision-making. It is expected that the findings of this dissertation will benefit further research on vehicle stability and safety as well as more advanced vehicle technologies, particularly in personalization technologies.

This book takes a look at fully automated, autonomous vehicles and discusses many open questions: How can autonomous vehicles be integrated into the current transportation system with diverse users and human drivers? Where do automated vehicles fall under current legal frameworks? What risks are associated with automation and how will society respond to these risks? How will the marketplace react to automated vehicles and what changes may be necessary for companies? Experts from Germany and the United States define key societal, engineering, and mobility issues related to the automation of vehicles. They discuss the decisions programmers of automated vehicles must make to enable vehicles to perceive their environment, interact with other road users, and choose actions that may have ethical consequences. The authors further identify expectations and concerns that will form the basis for individual and societal acceptance of autonomous driving. While the safety benefits of such vehicles are tremendous, the authors demonstrate that these benefits will only be achieved if vehicles have an appropriate safety concept at the heart of their design. Realizing the potential of automated vehicles to reorganize traffic and transform mobility of people and goods requires similar care in the design of vehicles and networks. By covering all of these topics, the book aims to provide a current, comprehensive, and scientifically sound treatment of the emerging field of “autonomous driving".

This book is the first technical overview of autonomous vehicles written for a general computing and engineering audience. The authors share their practical experiences of creating autonomous vehicle systems. These systems are complex, consisting of three major subsystems: (1) algorithms for localization, perception, and planning and control; (2) client systems, such as the robotics operating system and hardware platform; and (3) the cloud platform, which includes data storage, simulation, high-definition (HD) mapping, and deep learning model training. The algorithm subsystem extracts meaningful information from sensor raw data to understand its environment and make decisions about its actions. The client subsystem integrates these algorithms to meet real-time and reliability requirements. The cloud platform provides offline computing and storage capabilities for autonomous vehicles. Using the cloud platform, we are able to test new algorithms and update the HD map—plus, train better recognition, tracking, and decision models. This book consists of nine chapters. Chapter 1 provides an overview of autonomous vehicle systems; Chapter 2 focuses on localization technologies; Chapter 3 discusses traditional techniques used for perception; Chapter 4 discusses deep learning based techniques for perception; Chapter 5 introduces the planning and control sub-system, especially prediction and routing technologies; Chapter 6 focuses on motion planning and feedback control of the planning and control subsystem; Chapter 7 introduces reinforcement learning-based planning and control; Chapter 8 delves into the details of client systems design; and Chapter 9 provides the details of cloud platforms for autonomous driving. This book should be useful to students, researchers, and practitioners alike. Whether you are an undergraduate or a graduate student interested in autonomous driving, you will find herein a comprehensive overview of the whole autonomous vehicle technology stack. If you are an autonomous driving practitioner, the many practical techniques introduced in this book will be of interest to you. Researchers will also find plenty of references for an effective, deeper exploration of the various technologies.

Every year roughly 100,000 fatal and injury crashes occur in the United States involving large trucks and buses. The Federal Motor Carrier Safety Administration (FMCSA) in the U.S. Department of Transportation works to reduce crashes, injuries, and fatalities involving large trucks and buses. FMCSA uses information that is collected on the frequency of approximately 900 different violations of safety regulations discovered during (mainly) roadside inspections to assess motor carriers' compliance with Federal Motor Carrier Safety Regulations, as well as to evaluate their compliance in comparison with their peers. Through use of this information, FMCSA's Safety Measurement System (SMS) identifies carriers to receive its available interventions in order to reduce the risk of crashes across all carriers. Improving Motor Carrier Safety Measurement examines the effectiveness of the use of the percentile ranks produced by SMS for identifying high-risk carriers, and if not, what alternatives might be preferred. In addition, this report evaluates the accuracy and sufficiency of the data used by SMS, to assess whether other approaches to identifying unsafe carriers would identify high-risk carriers more effectively, and to reflect on how members of the public use the SMS and what effect making the SMS information public has had on reducing crashes.
