This report presents the methodology and results of the independent evaluation of a prototype integrated crash warning system for light vehicles as part of the Integrated Vehicle-Based Safety Systems initiative of the United States Department of Transportation's Intelligent Transportation System program. The system integrates rear-end crash, curve-speed warning, lane change crash, and lane departure warning functions. The goals of the independent evaluation are to assess the safety impact, gauge driver acceptance, and characterize the capability of the integrated safety system. The evaluation is based on naturalistic driving data collected from a field operational test using 108 subjects who drove 16 passenger vehicles equipped with a prototype integrated safety system and a data acquisition system. The test subjects accumulated over 213,000 miles during a 12-month period throughout parts of southeast Michigan. For each driver, the test period was divided into a 12 day baseline condition with the system disabled and a 28 day treatment condition with the system enabled to compare the effect of the system on driving performance. The results of the analysis suggest that driving with the integrated safety system improves driver behavior and increases driver safety, that drivers feel that the system provides a safety benefit, and that the system alerts had a high degree of accuracy. This report delineates the methodology of the different analyses and discusses their results.

This report identifies crash imminent test scenarios based on common pre-crash scenarios for integrated vehicle-based safety systems that alert the driver of a light vehicle or a heavy truck to an impending rear-end, lane change, or run-off-road crash. Pre-crash scenarios describe vehicle movements and critical events immediately prior to the crash. The General Estimates System (GES) crash database was queried to distinguish common pre-crash scenarios for light vehicles (2003 GES) and heavy trucks (2000-2003 GES) in terms of their frequency of occurrence. Analysis of two-vehicle rear-end crashes revealed four dominant scenarios that accounted for 97 percent of light-vehicle crashes and 95 percent of heavy-truck crashes in which the subject vehicle was striking. Four scenarios were also identified from an analysis of two-vehicle lane change crashes, comprising 65 percent of light-vehicle crashes and 76 percent of heavy-truck crashes in which the subject vehicle was encroaching onto another vehicle in adjacent lanes. There were five single-vehicle, run-off-road scenarios representing 63 percent of light-vehicle crashes and 83 percent of heavy-truck crashes, excluding crashes caused by vehicle failure or evasive maneuver. An additional set of scenarios is proposed to address multiple threats from near simultaneous critical events. This report also provides a statistical description of individual scenarios in terms of their environmental factors, roadway geometry, and speed conditions.

Even though a number of developed countries enjoy a high level of vehicle safety, more than 1.2 million fatalities still occur each year on roadways worldwide. There remains a need to continue improving vehicle and road safety. New technologies in sensors and electronic control units, and the growing knowledge of car-to-car and car-to-infrastructure technologies have led to a fusion of the previously separated areas of accident avoidance (popularly known as active safety) and mitigation of injuries (popularly known as passive safety) into the newer concept of integrated vehicle safety. This new approach represents a further step toward lowering accident rates. This book, written by two of the foremost automotive engineering safety experts, takes a unique and comprehensive approach to describing all areas of vehicle safety: accident avoidance, pre-crash, mitigation of injuries, and post-crash technologies, providing a solutions-based perspective of integrated vehicle safety. Also covered are accident investigation and worldwide legislation as they apply to integrated vehicle safety. The man-machine interface, biomechanics and development and simulation techniques are also key concepts that are thoroughly described. Special attention is given to driver assistance systems and to compatibility in car-to-car crashes and pedestrian protection. Chapters cover: accident research, functions of integrated safety, biomechanics and protection criteria, injury mitigation, adaptive occupant protection, compatibility, calculation and simulation, and the future. The book is useful for those interested in any aspect of automotive safety. Engineers and scientists from the automotive industry can learn new details as well as the broad perspective of vehicle safety today. The book also provides key information to traffic safety professionals, law enforcement, insurance practitioners, and journalists. Those who help shape traffic and vehicle legislation can gain a wider understanding of the topic to help them craft better laws. The book also serves as a valuable learning resource for academicians and students.

This report presents results from a series of on-road verification tests performed to determine the readiness of a prototype integrated warning system to advance to field testing, as well as to identify areas of system performance that should be improved prior to the start of the field test planned for 2009. Data was collected from tests conducted on public roads using a 2007 Honda Accord equipped with the prototype safety system. The system provides forward crash warning (FCW), lane departure warning (LDW), curve speed warning (CSW), and lane change/merge (LCM) functions, managed by an arbitration function that addresses multiple crash threats. The objectives of the on-road tests were to drive the test vehicle in an uncontrolled driving environment to measure the system's susceptibility to nuisance alerts, assess alerts in perceived crash situations, and evaluate system availability.

What is computational intelligence (CI)? Traditionally, CI is understood as a collection of methods from the ?elds of neural networks (NN), fuzzy logic and evolutionary computation. Various de?nitions and opinions exist, but what belongs to CI is still being debated; see, e.g., [1–3]. More recently there has been a proposal to de?ne the CI not in terms of the tools but in terms of challenging problems to be solved [4]. With this edited volume I have made an attempt to give a representative sample of contemporary CI activities in automotive applications to illustrate the state of the art. While CI researchand achievements in some specialized ?elds described (see, e.g., [5, 6]), this is the ?rst volume of its kind dedicated to automotive technology. As if re?ecting the general lack of consensus on what constitutes the ?eld of CI, this volume 1 illustrates automotive applications of not only neural and fuzzy computations which are considered to be the “standard” CI topics, but also others, such as decision trees, graphicalmodels, Support Vector Machines (SVM), multi-agent systems, etc. This book is neither an introductory text, nor a comprehensive overview of all CI research in this area. Hopefully, as a broad and representative sample of CI activities in automotive applications, it will be worth reading for both professionals and students. When the details appear insu?cient, the reader is encouraged to consult other relevant sources provided by the chapter authors.
