Book excerpt: This work is part of a multiyear program to foster the development, evaluation, and deployment of forward crash avoidance systems. The work performed during the first two years of this program addressed adaptive cruise control and warnings based upon the motion and proximity of preceding vehicles in the path of travel. The research work done in the first and second years has provided a foundation for the work performed in this third year. The technology-related work for the third year was focused upon the addition of braking to an UMRI prototype of an ACC system. The objective of this work is to provide test results and system-development experience showing the engineering and human factors issues posed by braking as a supplement to ACC or within a medium-deceleration crash avoidance function. The results indicated that the acceleration level used in increasing the speed of the ACC vehicle was not satisfactory in the opinion of most of the test drivers. Drivers did not want to slow down too much because they were concerned with how long it would take to get back up to the desired speed and headway time gap. They indicated that the resume rate of the system was the system's weakness. With regard to the buzzer that was used to warn the driver when the system was asking for the maximum deceleration authority, there were some drivers who did not like buzzers in general and some drivers who thought the features of this buzzer could be improved. The ratings concerning the deceleration level, the following control, and the system's smoothness were quite good. It is recommended that a simple rule for modulating the throttle should be used to achieve the basic ACC functionality. Braking should be applied in a progressively increasing manner, and it should be used to adjust vehicle deceleration in a way that will lead to headway time and distance gaps such that throttle modulation can control headway. Every effort should be made to improve the forward-acceleration capability of the vehicle when it is under ACC control. The warning system should have a nonaggressive signal to inform the driver when braking at the full-deceleration authority of the ACC system has been reached. Further consideration should be given to adding another, more aggressive, signal to warn the driver when the deceleration needed to barely avoid a crash exceeds the control authority of the ACC system.

Available in PDF, EPUB and Kindle. Book excerpt: Over the past thirty-five years, a tremendous body of both theoretical and empirical research has been established on the `science of transportation'. The Handbook of Transportation Science has collected and synthesized this research into a systematic treatment of this field covering its fundamental concepts, methods, and principles. The purpose of this handbook is to define transportation as a scientific discipline that transcends transportation technology and methods. Whether by car, truck, airplane - or by a mode of transportation that has not yet been conceived - transportation obeys fundamental properties. The science of transportation defines these properties, and demonstrates how our knowledge of one mode of transportation can be used to explain the behavior of another. Transportation scientists are motivated by the desire to explain spatial interactions that result in movement of people or objects from place to place. Its methodologies draw from physics, operations research, probability and control theory. It is fundamentally a quantitative discipline, relying on mathematical models and optimization algorithms to explain the phenomena of transportation. The fourteen chapters in the handbook are written by the leading researchers in transportation science in an effort to define and categorize for the first time the scientific nature and state of the art of the field. As such, it is directed to the broader research community, transportation practitioners, and future transportation scientists.

Available in PDF, EPUB and Kindle. Book excerpt: Featuring contributions from leading experts, the Road and Off-Road Vehicle System Dynamics Handbook provides comprehensive, authoritative coverage of all the major issues involved in road vehicle dynamic behavior. While the focus is on automobiles, this book also highlights motorcycles, heavy commercial vehicles, and off-road vehicles. The authors of the individual chapters, both from automotive industry and universities, address basic issues, but also include references to significant papers for further reading. Thus the handbook is devoted both to the beginner, wishing to acquire basic knowledge on a specific topic, and to the experienced engineer or scientist, wishing to have up-to-date information on a particular subject. It can also be used as a textbook for master courses at universities. The handbook begins with a short history of road and off-road vehicle dynamics followed by detailed, state-of-the-art chapters on modeling, analysis and optimization in vehicle system dynamics, vehicle concepts and aerodynamics, pneumatic tires and contact wheel-road/off-road, modeling vehicle subsystems, vehicle dynamics and active safety, man-vehicle interaction, intelligent vehicle systems, and road accident reconstruction and passive safety. Provides extensive coverage of modeling, simulation, and analysis techniques Surveys all vehicle subsystems from a vehicle dynamics point of view Focuses on pneumatic tires and contact wheel-road/off-road Discusses intelligent vehicle systems technologies and active safety Considers safety factors and accident reconstruction procedures Includes chapters written by leading experts from all over the world This text provides an applicable source of information for all people interested in a deeper understanding of road vehicle dynamics and related problems.

Book excerpt: A comprehensive review and analysis of the human factors research associated with the implementation of crash warning system interfaces has led to the development of guidelines intended to be used by anyone responsible for the conceptualization, development, design, testing, or evaluation of in-vehicle crash avoidance systems, especially for forward collision (headway warning), lane change (blind-spot warning), and road departure warnings. This book is intended to highlight issues to be addressed and provide guidance in the development of Collision Warning Systems (CWSs). Information is presented on a variety of topics relevant to the driver-vehicle interface (DVI) of CWS devices.
