Book Description
"Abstract: Characterization test procedures have been developed to quantify the performance of intersection collision avoidance (ICA) systems based on vehicle-to-vehicle communications. These systems warn the driver of an imminent crossing-path collision at a road junction, and apply automatic braking if the driver does not respond in a timely manner to prevent the collision. This report describes test procedures for most common crossing-path pre-crash scenarios that involve light vehicles (passenger cars, vans, minivans, SUVs, or light pickup trucks with gross vehicle weight ratings less than 10,000 pounds). The test procedures include crash-imminent test scenarios to collect information on the ranges and time-to-collisions of crossing-path collision alerts and automatic braking onsets in prototype systems. In addition, the test procedures incorporate dynamic scenarios where countermeasure action is not needed so as to assess the capability of ICA systems to distinguish between crash-imminent and benign driving scenarios."--Technical report documentation page.

Book Description
Provides an up-to-date, in-depth look at the current research, design, and implementation of cooperative vehicle safety communication protocols and technology Improving traffic safety has been a top concern for transportation agencies around the world and the focus of heavy research and development efforts sponsored by both governments and private industries. Cooperative vehicle systems—which use sensors and wireless technologies to reduce traffic accidents—can play a major role in making the world's roads safer. Vehicle Safety Communications: Protocols, Security, and Privacy describes fundamental issues in cooperative vehicle safety and recent advances in technologies for enabling cooperative vehicle safety. It gives an overview of traditional vehicle safety issues, the evolution of vehicle safety technologies, and the need for cooperative systems where vehicles work together to reduce the number of crashes or mitigate damage when crashes become unavoidable. Authored by two top industry professionals, the book: Summarizes the history and current status of 5.9 GHz Dedicated Short Range Communications (DSRC) technology and standardization, discussing key issues in applying DSRC to support cooperative vehicle safety Features an in-depth overview of on-board equipment (OBE) and roadside equipment (RSE) by describing sample designs to illustrate the key issues and potential solutions Takes on security and privacy protection requirements and challenges, including how to design privacy-preserving digital certificate management systems and how to evict misbehaving vehicles Includes coverage of vehicle-to-infrastructure (V2I) communications like intersection collision avoidance applications and vehicle-to-vehicle (V2V) communications like extended electronic brake lights and intersection movement assist Vehicle Safety Communications is ideal for anyone working in the areas of—or studying—cooperative vehicle safety and vehicle communications.

Book Description
This report describes the system capability assessment for the Cooperative Intersection Collision Avoidance System for Violations (CICAS-V) based on data collected from objective tests and a pilot test. The CICAS-V is a vehicle-to-infrastructure system that provides visual, audio, and haptic (brake pulse) warnings when a vehicle is in danger of violating a traffic signal or stop sign at an intersection. A series of objective tests were conducted at the Virginia Tech Transportation Institute. Each test was defined by an initial geometry, a set of validity constraints (such as the sufficient GPS accuracy), and a set of pass/fail criteria. The test series investigated the ability to appropriately warn or not warn at various speeds, in appropriately discerned lanes, under dynamic lane changes, under changing signal conditions, and in the presence of multiple equipped intersections. A pilot test was run with nearly 100 naïve drivers on a two-hour prescribed course in the Blacksburg, VA area.

Book Description
Millions of automobile accidents occur worldwide each year. Some of the most serious are rear-end crashes, side crashes within intersections, and crashes that occur when cars change lanes or drift into a lane. The holy grail of traffic safety is to avoid automobile accidents altogether. To that end, major automakers, governments, and universities are working on systems that allow vehicles to communicate with one another as well as the surrounding infrastructure (V2V/V2I for short). These systems show promise for such functions as intersection assist, left-turn assist, do-not-pass warning, advance warning of a vehicle braking ahead, forward-collision warning, and blind-spot/lane-change warning. This compendium explores the challenges in developing these systems and provides the latest developments in V2V/V2I technology. It begins with a series of overview news stories and articles from SAE’s magazines on the progress in this technology. This is followed by a series of technical papers on V2V/V2I dealing with the many technical aspects of design of these systems as well as discussions of such key issues as the need for extreme reliability assurances and traffic congestion overloads on the systems. Some of most interesting discussions in the book include: • Overview of a large-scale test in Germany to address reliability. • Effectiveness of different antennas and receivers that are used in various intersections settings, such as intersections where there are tall buildings or no buildings, and where high transmission power lines are located that can cause signal interference. • Various ways to communicate between vehicles and how messages are relayed to drivers. • Dedicated short range communication protocol for vehicle safety applications, which shows promise for combining and processing large amounts of information. Editor Ronald K. Jurgen prepared this book to be of use to engineers at automakers and electronic component suppliers; software engineers; computer systems analysts and architects; academics and researchers within the electronics, computing, and automotive industries; legislators, managers and other decision-makers in the government highway sector; traffic safety professionals; and insurance and legal practitioners. Mr. Jurgen served on the editorial staff of IEEE Spectrum for 30 years and is the editor of several electronics-related handbooks and several other electronics-related compendiums published by SAE International.

Book Description
This report describes the National Institute of Standards and Technology's role in the Integrated Vehicle-Based Safety Systems (IVBSS) program, a four-year safety initiative sponsored by the United States Department of Transportation (U.S. DOT) to develop and field test an integrated crash warning system to prevent rear-end, lane-change/merge and road departure crashes on light vehicles and heavy commercial trucks. NIST's primary role in the program included assisting in the development of verification test procedures, developing a measurement system, and providing field support for vehicle test activities. NIST used the measurement system to collect data for determining whether the prototype warning systems passed or failed all closed-course track tests and for characterizing warning system performance on public roads
