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.

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: 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 2016 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: Truck safety is a very crucial aspect of the overall safety of the transportation system. Statewide there has been a significant increase in the probability of trucks being involved in crashes, primarily due to the fact that the total number of registered trucks, as well as the truck vehicle-miles traveled, have both increased within the last 10 years. Recognizing the substantial impact of truck-related crashes in the overall transportation safety, this study attempted to identify the contributing factors that influence the increase in truck-related crash severity, using truck-related crash data for the last two and half years (July 2013-December 2015) that were obtained from the Ohio Department of Public Safety Traffic (ODPS). This thesis study used the classification tree model to investigate the important factors affecting injury and fatality related to truck crashes in Ohio. Eighteen independent variables that represent various driver, roadway, environmental and crash characteristics were tested in the classification tree model of truck-related crash model. The dependent variable, crash severity was coded as a binary variable, with no injury and injury/fatal as its two crash severity levels. The classification tree model selected five independent variables as the only most significant factors influencing truck-related crash severity. These variables are crash type, posted speed limit, collision event, speed-related and road contour. Their significance is also in that order, with the crash type being the most significant, contributing about 55.8% to the model, posted speed limit contributing about 18.5%, collision event about 17.7%, speed-related about 6.0% and lastly road contour about 2.0%

Book Synopsis Investigation of Traffic Crashes in Two-lane Rural Highways in Ohio by : Abdullah Alhomidan
Download or read book Investigation of Traffic Crashes in Two-lane Rural Highways in Ohio written by Abdullah Alhomidan and published by . This book was released on 2006 with total page 133 pages. Available in PDF, EPUB and Kindle. Book excerpt: Traffic crashes continue to be a major concern on the U.S roads. Rural highways represent the largest single class of highways in the United States, and account for approximately 80 percent of all paved highways. Two-lane highways compose of more than 85 per cent of all rural highways. Most of the existing studies on the deer-vehicle-crash (DVC) and run-off-road (ROR) crashes are based on crash reports only, and there are some conflicting findings on the major contributing factors to the crashes. In this study we investigate the most common types of crashes on two-lane rural highways. We find that the deer-vehicle-crashes and the run-off-road crashes represent the majority of the crashes in a sample of 1208 non-intersections crashes that occurred in 173.5 miles of roadways in the Ashtabula County, Ohio. The investigation procedure begins with identifying the high crashes sections, followed by field surveys, and statistical analysis. The statistical analysis showed that the percentage of the wooded area located less than 30 ft from the highway edge is the most important factor that can be used to distinguish the high DVC sections from the other sections. Similarly, the percentage of the non-forgiving shoulders is the most important factor to distinguish between the high ROR sections from the other sections. In addition, the correlation analysis showed weak connection between the high DVC sections and the high ROR sections. Field experiments have been conducted to collect additional data unavailable in the crash reports. The experimental results suggest that the depth of clear zone (by removing trees and bushes) in the wooded area should be no more than 40 ft on each side of the highway. To increase highway lights, the areas that need to be lit are between 27 to 38 feet from the side of the highway. The results also suggest that deer warning signs have little influence on the drivers to reduce speeds or switch from low to high beams. Future studies may include investigation of the effectiveness of the countermeasures for DVC. Additional work is also needed to study the behavioral factors of drivers in the ROR crashes once data are available.

This book was released on 2016 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this study was to examine the contributing factors and characteristics associated with fatality and injuries sustained by drivers of emergency vehicles (EVs) involved in traffic crashes in the state of Ohio. Emergence vehicle drivers considered in this study include drivers of firefighter truck, drivers of ambulances (emergency medical services), and law enforcement officers. Some few research efforts recently conducted using Ohio0́9s crash data have shown that emergency vehicles are significant factors in increasing crash and injury severity levels. The current study investigated the injury risk factors of crashes involving EVs by using Ohio crash data for 2011-2015. A binary logistic regression model was developed to identify statistically significant factors related to fatalities and injuries of EV drivers. The logistic regression model identified fourteen factors. Significant factors identified include type of crash, collision type, speed related, traffic control type, alcohol related, type of emergency vehicle, emergency related trip, female driver, light condition, teen-related, not using seatbelt, curved and grade segment. Educational and enforcement strategies can be used to reduce EV related crashes and injuries.

Download or read book Data Analytics for Smart Cities written by Amir Alavi and published by CRC Press. This book was released on 2018-10-26 with total page 243 pages. Available in PDF, EPUB and Kindle. Book excerpt: The development of smart cities is one of the most important challenges over the next few decades. Governments and companies are leveraging billions of dollars in public and private funds for smart cities. Next generation smart cities are heavily dependent on distributed smart sensing systems and devices to monitor the urban infrastructure. The smart sensor networks serve as autonomous intelligent nodes to measure a variety of physical or environmental parameters. They should react in time, establish automated control, and collect information for intelligent decision-making. In this context, one of the major tasks is to develop advanced frameworks for the interpretation of the huge amount of information provided by the emerging testing and monitoring systems. Data Analytics for Smart Cities brings together some of the most exciting new developments in the area of integrating advanced data analytics systems into smart cities along with complementary technological paradigms such as cloud computing and Internet of Things (IoT). The book serves as a reference for researchers and engineers in domains of advanced computation, optimization, and data mining for smart civil infrastructure condition assessment, dynamic visualization, intelligent transportation systems (ITS), cyber-physical systems, and smart construction technologies. The chapters are presented in a hands-on manner to facilitate researchers in tackling applications. Arguably, data analytics technologies play a key role in tackling the challenge of creating smart cities. Data analytics applications involve collecting, integrating, and preparing time- and space-dependent data produced by sensors, complex engineered systems, and physical assets, followed by developing and testing analytical models to verify the accuracy of results. This book covers this multidisciplinary field and examines multiple paradigms such as machine learning, pattern recognition, statistics, intelligent databases, knowledge acquisition, data visualization, high performance computing, and expert systems. The book explores new territory by discussing the cutting-edge concept of Big Data analytics for interpreting massive amounts of data in smart city applications.
