Book Description
The objective of the Cooperative Intersection Collision Avoidance System for Violations (CICAS-V) Project is to develop and field-test a comprehensive system to reduce the number of crashes at intersections due to violations of traffic control devices (TCDs; i.e., traffic lights and stop signs). The CICAS-V system provides a salient and timely in-vehicle warning to drivers who are predicted to violate a TCD, with the aim of compelling the driver to stop. This report presents the final summary report of the CICAS-V Project.

Book Description
This report presents the Midterm Phase I Report for the Cooperative Intersection Collision Avoidance System Limited to Stop Sign and Traffic Signal Violations (CICASV) project. The report covers the period from project inception on May 1, 2006, through April 30, 2007, and contains a summary of the tasks that were active during the first year of the project. These tasks, collectively, address four major elements of the research needed to develop an FOT-ready system by the end of Phase I. These elements are: (a) human factors research to identify a driver-vehicle interface (DVI) for the CICAS-V system and the operational parameters for the driver warning algorithm; (b) systems engineering activities to design the CICAS-V system; (c) system development and validation tasks to build and test a prototype FOT system; and (d) project management and coordination with outside organizations. The progress made during the period and the accomplishments achieved are also described in the report. The CICAS-V project is a four-year project to develop a cooperative intersection collision avoidance system to assist drivers in avoiding crashes in the intersection by warning the driver of an impending violation of a traffic signal or a stop sign. The Vehicle Safety Communications 2 Consortium (VSC2) is executing the project. Members of VSC2 are Ford Motor Company, General Motors Corporation, Honda R & D Americas, Inc., Mercedes-Benz Research and Development North America, Inc., and Toyota Motor Engineering & Manufacturing North America, Inc.

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
This report documents the results of the independent evaluation's assessment of the driver acceptance of the Cooperative Intersection Collision Avoidance System limited to Stop Sign and Traffic Signal Violations (CICAS-V) system as tested during a pilot test in 2008. The purpose of this pilot test was to use naïve participants in on-road and test-track environments to assess the readiness and maturity of the CICAS-V for a large-scale field operational test. Data were evaluated from 87 naive drivers who were placed into equipped vehicles to navigate a two-hour prescribed route through ten stop-controlled and three signal-controlled equipped intersections. To ensure the data were sufficient to understand drivers' impressions of the warning, 18 drivers followed the on-road study with a test-track study.

Book Description
Crashes at rural thru-stop intersections arise primarily from a driver attempting to cross or enter the mainline traffic stream after failing to recognize an unsafe gap condition. Because the primary cause of these crashes is not failure to stop, but failure to recognize an unsafe condition, the US DOT FHWA, Mn/DOT, and the University of Minnesota ITS Institute undertook the Cooperative Intersection Collision Avoidance System – Stop Sign Assist (CICAS-SSA) program. CICAS-SSA uses roadside radar sensors, a computer processor and algorithms to determine unsafe conditions, and an active LED icon based sign to provide timely alerts and warnings which are designed to reduce the frequency of crashes at rural expressway intersections.

Book Description
The deployment of a Cooperative Intersection Collision Avoidance System – Stop Sign Assist (CICAS-SSA) can save lives by addressing the causal factor of crashes at rural thru-Stop intersection: drivers who stop on the minor leg of the intersection, improperly assess the gaps in the traffic on the major leg, proceed, and are then hit.

Book Description
The deployment of a Cooperative Intersection Collision Avoidance System – Stop Sign Assist (CICAS-SSA) can save lives by addressing the causal factor of crashes at rural thru-Stop intersection: drivers who stop on the minor leg of the intersection, improperly assess the gaps in the traffic on the major leg, proceed, and are then hit. The prototype CICAS-SSA system consisted of a network of sensors covering both the minor and the major legs of the intersection. Sensors on the minor road monitored the approach of vehicles and classified them based on their length and height. Sensors along the major road were arrayed to track vehicles (and the gaps between them) approaching the crossroads from 2000 feet away as a means to ensure that the tracking algorithm had sufficient time to “lock on” and track all approaching vehicles. Because cost is a primary concern for any highway safety application, the development of a “minimal sensor set” which would provide adequate safety performance for minimum cost was paramount to the success of the CICAS-SSA program. This report documents the development of this minimal sensor configuration.

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.
