Book Description
From May 2004 to February 2005, 78 drivers participated in a field operational test of Road-Departure Crash Warning system. The RDCW warned drivers when they were drifting out of their lane or were about to enter a curve at an unsafe speed.

Book Description
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.

Book Description
The Minnesota Department of Transportation (MnDOT) is investing significant resources in intersection collision warning systems (ICWS) based on early indications of effectiveness. However, the effectiveness is not well documented, and negative changes in driver behavior at treatment intersections may affect drivers overall, resulting in a spillover effect. Moreover, the effectiveness of ICWS may decrease if drivers do not perceive a change in the dynamic messages. Therefore, the objectives of this research were to (1) evaluate driver behavior at mainline and stop-controlled approaches for intersections with and without ICWS and (2) assess the traffic volume range and limits where the system is nearly continuously activated and is likely to lose its effectiveness. Video data were collected at five treatment and corresponding control intersections, and various metrics were used to compare changes in driver behavior. In general, no negative behaviors were noted for either treatment or control intersections.

Book Description
The Independent Measurement System (IMS) is a generalpurpose measurement system designed for collecting and analyzing data needed for evaluation of intelligent vehicle systems. The IMS consists of sensors, data collection hardware and analysis software independent of the system under test. This provides objectivity, quality assurance and redundancy to data collection and testing activities. The following version of the IMS supports testing and performance evaluation of the road departure crash warning system (RDCWS) developed for a Department of Transportation Field Operation Test under the Intelligent Vehicle Initiative.

Book Description
Excerpt from An Independent Measurement System for Performance Evaluation of Road Departure Crash Warning Systems Section 3 describes the visual targets for camera calibration and their proper use. Section 4 describes the camera calibration process. Section 5 describes how evaluators process the data to produce the final video, gps and support files. Section 6 describes the data analysis tools including controls and displays for scrolling through the video, plotting vehicle trajectory, viewing time and making a variety of road measurements.

Book Description
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.
