This book was released on 2007 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2011-10-31 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: The purpose of the Integrated Vehicle-Based Safety System (IVBSS) project is to evaluate the potential safety benefits and driver acceptance of an integrated set of crash-warning technologies installed on both heavy truck and light vehicle platforms. IVBSS is an integrated set of technologies that is intended to help the driver avoid road-departure, rear-end, and lane-change crashes by providing occasional crash alerts and advisories to enhance the driver’s awareness of the driving situation. This document proposes functional requirements for the system to be developed and field-tested on the heavy truck platform. These requirements are generated solely for the system created within this project, and are not intended to be prescriptive for integrated crash systems developed outside the project. The heavy truck platform encompasses class 8 trucks operating with one trailer or without a trailer. The IVBSS on the heavy truck platform addresses the following crash types: · Road departures due to unintended lateral drift, · Rear-end crashes, and· Lane-change and merge crashes due to unsafe lane movements by the heavy truck.

Book excerpt: This document presents the plan for conducting a field operational test (FOT) of the Integrated Vehicle-Based Safety Systems (IVBSS) program. The plan describes the work that will be performed by the University of Michigan Transportation Research Institute using 16 passenger cars and 10 commercial trucks equipped with an integrated crash avoidance system. The purpose of the IVBSS program is to evaluate the suitability of a state-of-the-art integrated crash warning system for widespread deployment in the U.S. passenger car and commercial truck fleet. Both platforms have three integrated crash-warning subsystem systems (forward crash, lateral drift, and lane-change/merge warnings); the light-vehicle platform also has a fourth subsystem, curve-speed warning. For the light vehicle portion of the FOT, lay drivers will operate test vehicles in place of their own personal cars for a period of six weeks. Commercial-truck drivers from a commercial fleet will operate heavy trucks in place of the Class 8 tractors they normally use as their work vehicles. All vehicles will be instrumented to capture information regarding the driving environment, driver activity, system behavior, and vehicle kinematics. Driver information will be captured through a series of subjective questionnaires, focus groups, and debriefing sessions to determine driver acceptance and to gain insight for improving future versions of integrated crash warning systems.

Download or read book Integrated Vehicle Based Safety System written by and published by . This book was released on 2007 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Integrated Vehicle-Based Safety Systems (IVBSS) program is a four-year, two phase cooperative research program conducted by an industry team led by the University of Michigan Transportation Research Institute (UMTRI). The program goal is to integrate several collision warning systems into one vehicle in a way that alerts drivers to potential collision threats with an effective driver vehicle interface (DVI), while minimizing the number of excessive warnings presented to the driver. Basic program strategies for meeting this objective include systematically managing and prioritizing all information presented to the driver, minimizing the number of system false alarms, and restricting auditory alarms to higher urgency collision conditions. This report presents a series of analyses conducted by the DVI team on a subset of relevant driving scenarios to identify: the applicable warning algorithms, the corresponding DVI output, any potential ambiguities or conflicts in defining these detection algorithms and DVI outputs, and any potential issues in the time available to the driver to respond to the IVBSS warning.

This book was released on 2008 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of the Integrated Vehicle-Based Safety System (IVBSS) project is to evaluate the potential safety benefits and driver acceptance of an integrated set of crash-warning technologies installed on both light-vehicle and heavy-truck platforms. The IVBSS is an integrated set of technologies that is intended to help the driver avoid crashes by providing crash alerts in potential crash-imminent situations and advisories to enhance the driver's awareness of the driving situation.This report proposes quantitative and measurable performance metrics that are considered achievable and appropriate for the IVBSS system on a heavy truck (Class 8). The guidelines build upon previous project reports that present functional requirements. This effort also borrows from previous specification efforts for stand-alone crash warning systems - especially prior U.S. DOT projects and ISO standards efforts. However the focus is on the integration of these functions. In some performance areas, integration allows improvements in potential safety benefits through enhanced system awareness. In other areas, integration presents a challenge, especially in ensuring driver acceptance because the broad scope of IVBSS means more potential sources of false or nuisance alerts.

This book was released on 2015 with total page 45 pages. Available in PDF, EPUB and Kindle. Book excerpt: "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.

Najm and published by Createspace Independent Publishing Platform. This book was released on 2013-04-30 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: A template of pre-crash scenarios is presented to depict national crash statistics and kinematic information of time-to-collision for the design of appropriate crash countermeasures based on vehicle-to-vehicle (V2V) communications. This template serves the development of functional requirements, performance specifications, test procedures, and benefits estimation for potential light-vehicle V2V safety applications. A set of ten pre-crash scenarios is suggested as a priority list to be addressed by V2V technology for light vehicles (i.e., passenger cars, vans and minivans, sport utility vehicles, and light pickup trucks with gross vehicle weight ratings of 10,000 pounds or less). This report presents the time-to-collision equations as well as the crash statistics for each of the ten priority scenarios based on data available in the General Estimates System, National Motor Vehicle Crash Causation Survey, and Event Data Recorder databases.
Download or read book Integrated Vehicle based Safety Systems Light vehicle Field Operational Test Key Findings Report written by and published by . This book was released on 2011 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document presents key findings from the light-vehicle field operational test conducted as part of the Integrated Vehicle-Based Safety Systems program. These findings are the result of analyses performed by the University of Michigan Transportation Research Institute to examine the effects of a prototype integrated crash warning system on driving behavior and driver acceptance. The light-vehicle platform included four integrated crash-warning subsystems (forward-crash, lateral-drift, lane-change/merge crash, and curve-speed warnings) installed on a fleet of 16 passenger cars and operated by 108 randomly-sampled drivers for a period of six weeks each. Each car was instrumented to capture detailed data on the driving environment, driver behavior, warning system activity, and vehicle kinematics. Data on driver acceptance was collected through a post-drive survey, debriefings and focus groups. Key findings indicate that use of the integrated crash warning system resulted in improvements in lane-keeping, fewer lane departures, and increased turn-signal use. The research also indicated that drivers were slightly more likely to maintain shorter headways with the integrated system. No negative behavioral adaptation effects were observed as a result of drivers' involvement in secondary task behaviors. Drivers generally accepted the integrated crash warning system and 72 percent of all drivers said they would like to have an integrated warning system in their personal vehicles. Drivers also reported that they found the blind-spot detection component of the lane-change/merge crash warning system to be the most useful and satisfying aspect of the integrated system.
