Available in PDF, EPUB and Kindle. Book excerpt: Run-off-road (ROR) crashes, which usually involve only a single vehicle, contribute to a large portion of fatalities and serious injuries to motor vehicle occupants. In this study, the National Motor Vehicle Crash Causation Survey (NMVCCS) data collected at crash scenes between 2005 and 2007 is used to identify the ROR critical pre-crash event, assess the critical reason for the ROR critical event, and examine associated factors present in the pre-crash phase of the ROR crash. The effect of antilock brake system (ABS) and electronic stability control (ESC) on ROR crashes is also evaluated.

This book was released on 2013 with total page 77 pages. Available in PDF, EPUB and Kindle. Book excerpt: A run-off-road (ROR) crash or a roadway departure crash is a non-intersection crash which occurs after a vehicle crosses an edge line or a center line (i.e., leaves its designated traveled way and in the process the vehicle collides with a non-traversable obstacle or another vehicle travelling in the opposite direction or hits a pedestrian, or the vehicle overturns. The main objective of this thesis study was to determine the factors that contribute significantly to the levels of injury severity when ROR crashes occur. This study used a 5-year crash data for years 2008 - 2012 obtained from the Ohio Department of Public Safety. The decision tree model in conjunction with generalized ordered logit model was used to investigate characteristics of injury and fatality of run-off-road crashes in Ohio. The decision tree modeling was used for exploratory data analysis identified eight factors that explain a large amount of the variation in the response variable, injury severity. These important predictors for injury severity include road condition, run-off-road (ROR) crash types, posted speed limit, vehicle type, gender, alcohol-related, road contour, and drug-related. Also, complex interactions between parameters were identified. The results from the generalized ordered logit regression show that the following are significant factors in increasing the likelihood of ROR injury severity levels: alcohol and drugs use, curves and grades, female victims, overturn/rollover crashes, ROR crashes on dry roadway surfaces. Additionally, buses, truck, and emergency vehicles, and ROR crashes on roadways with posted speed limits of 40 mph or higher increase the probability of injury severity.

Book excerpt: Run-Off-Road crashes cause a large proportion of fatalities and serious injuries to the vehicle occupants. In this study, fatal crashes from the Fatality Analysis Reporting System for passenger vehicles (passenger cars and LTVs) during the period 1991 to 2007 wre used to identify the roadway- (e.g., rural/urban nature and curve existence), driver- (e.g., age, gender, drowsy, and alcohol use), environmental- (e.g., weather, lighting condition), and vehicle-related factors (e.g., speeding) associated with the fatal single vehicle run-off-road crashes.

This book was released on 2014 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: A vehicle that leaves its travel lane at a non-intersection location and collides with another vehicle or with a fixed object or overturns is considered to be involved in a run-off-road (ROR) crash. ROR crashes also known as roadway departure crashes, and these include head-on crashes, crashes that occur due to lane shifts, and crashes where the vehicle leaves its designated travel lane. The main objective of this study was to identify the significant factors that lead to these types of crashes. Crash data used in this study were obtained from the Ohio Department of Public Safety for a five-year period from 2008 to 2012. The classification tree modeling was used in this study to investigate the significant predictor variables of crash severity of ROR crashes. In addition, this thesis study developed two models, the ROR crashes model and the non-run-off-road (NROR) crashes model. The NROR crashes model used crash data for drivers who were at fault when their crash incidents occurred and for ROR crashes; it was assumed that all drivers in this category were at fault of causing the crashes. The ROR model identified nine variables, which include road condition, collision type, alcohol related, posted speed limit, speed related, crash type, vehicle type, gender, and age. The NROR crashes model has six significant predictor variables including collision type, posted speed limit, speed related, road condition, alcohol related, and vehicle type.

Available in PDF, EPUB and Kindle. Book excerpt: The objectives of this project are to assess the existing single vehicle run- off-the road (ROR) accident problem on rural highways in New Mexico, and to explore alternative techniques for its correction. These accidents account for nearly 45% of the state's highway fatalities. Application of the critical rate technique found that 26% of the New Mexico's rural interstate highway system and 22% of the rural Federal-Aid Primary mileage had actual ROR accident rates in excess of the critical values; the rates on the Federal-Aid Secondary system were even higher: traditional countermeasures have been employed with varying degrees of effectiveness at spot locations, but short of roadway reconstruction, little has been done for extended roadway sections. The placement of indented strips on roadway shoulders appears to be the most promising treatment for these sections. Reductions of up to 50% of ROR accidents have been achieved with this relatively inexpensive measure. New Mexico began installing this countermeasure in 1990, and evaluations will be conducted following a suitable after-period.

Book Synopsis Analysis of Run-off-the-road Crashes Involving Overcorrection by : Abhishek Mishra
Download or read book Analysis of Run-off-the-road Crashes Involving Overcorrection written by Abhishek Mishra and published by . This book was released on 2006 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: Overcorrection crashes have long been a concern in crash analysis because the outcomes vary from the vehicle coming to rest after a rollover, to the vehicle passing through the opposite lanes either hitting or without hitting an oncoming vehicle, to rear end and sideswipe impacts. These crashes occur when a vehicle begins drifting off the road one way and the driver oversteers in the opposite direction resulting in a vehicle- vehicle, fixed object, or overturning crash. While analyzing fatal crash data from the year 2000 in the state of Florida, it was found that these crashes represented around 25 % of the total number of run-off-the-road (ROR) crashes. With that intention, this research developed models to identify the factors that influence ROR crashes involving overcorrection.

Book Synopsis Development of Crash Imminent Test Scenarios for Integrated Vehicle-Based Safety Systems (IVBSS) by : Wassim Najm
Download or read book Development of Crash Imminent Test Scenarios for Integrated Vehicle-Based Safety Systems (IVBSS) written by Wassim Najm and published by Createspace Independent Publishing Platform. 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.
