Book excerpt: The analyses results of a transport airplane Controlled Impact Demonstration (CID) test using programs KRASH are described. Pre-CID analyses, presented in FAA technical report DOT/FAA/CT-85/9, are provided in summary form. The KRASH post CID correlation consists of modeling two sequences; a symmetrical impact of the fuselage with the ground (after engine-loss at initial air-to-ground impact) and the unsymmetrical air-to-ground including initial engine ground contact and subsequent fuselage impact with the ground. The analyses and test results are compared with regard to floor acceleration responses, fuselage shear and bending moment distribution, wing and engine acceleration responses, wing bending moment distribution, structural failures, fuselage underside crush, and sequence of events. Keywords: Aircraft fires; Aviation safety; Crash landings; Crash resistance; Aviation accidents.

Download or read book Correlation Analysis for Freeway Traffic Status and Crashes with Nevada Data written by Hao Xu and published by . This book was released on 2017 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: This project is to study the correlation between freeway traffic status and crash risks with the historical freeway ITS data and related crash data in Nevada. With the comprehensive review of previous research results, the Center for Advanced Transportation Education and Research at University of Nevada, Reno analyzed the interactive relationship between the freeway traffic status and crashes. The research developed a new method to correct the crash time that was not accurately documented in the crash report. A crash risk prediction model has been developed to estimate the influences of traffic status on collision risk. The impact of crash severity and crash type on after-crash traffic flows was also analyzed. The prediction models can be used to estimate the collision possibilities based on the real time ITS data. The models and analysis were based on the Nevada data so that they can be directly applied on Nevada freeways without additional calibration effort.

Available in PDF, EPUB and Kindle. Book excerpt: PennDOT engaged Gannett Fleming to conduct research into best practices in the use of geospatial analysis tools for highway safety analyses. The goals of the effort were to define a methodology for PennDOT to follow in identifying the best candidate locations for highway safety improvements, and to develop a Proof of Concept to test the proposed methodology. After conducting interviews and workshops involving more than 35 of PennDOT's stakeholders in highway safety processes, Gannett Fleming interviewed highway safety managers in five other state and federal highway agencies to determine what innovative tools and practices are currently being used. Gannett Fleming's research also included a review of literature related to the study from more than 80 sources. Based on Gannett Fleming's research and analysis, PennDOT selected the "Highway Safety Data Relationships Knowledge Base" for further research. The knowledge base is an information repository based on concepts in data mining and expert systems. It uses advanced statistical analysis methods and expert business knowledge rules to discover data patterns based on correlation and other forms of relationships in the data. The knowledge base can be applied to diagnosing specific combinations of data attributes and features that may indicate the causative factors among homogeneous populations of crashes. Most highway safety data analyses involve studying correlations among multiple data sets. The knowledge base is an innovative and compreh3nsive tool for such an application. It provides a framework for identifying and managing relationships among many combinations of data sets that are useful in highway safety analyses. Gannett Fleming proceeded to develop a prototype as a proof of concept. Gannett Fleming demonstrated the prototype using actual PennDOT crash data. Three analysis scenarios were demonstrated" evaluating safety programming alternatives for alcohol involved crashes, diagnosing data patterns of crashes at a selected highway location, identifying potential sites for system-wide deployment of a selected countermeasure

Available in PDF, EPUB and Kindle. Book excerpt: In its first centennial, aerospace has matured from a pioneering activity to an indispensable enabler of our daily life activities. In the next twenty to thirty years, aerospace will face a tremendous challenge - the development of flying objects that do not depend on fossil fuels. The twenty-three chapters in this book capture some of the new technologies and methods that are currently being developed to enable sustainable air transport and space flight. It clearly illustrates the multi-disciplinary character of aerospace engineering, and the fact that the challenges of air transportation and space missions continue to call for the most innovative solutions and daring concepts.

This book was released on 2018-11-02 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: The last ten years have seen explosive growth in the technology available to the collision analyst, changing the way reconstruction is practiced in fundamental ways. The greatest technological advances for the crash reconstruction community have come in the realms of photogrammetry and digital media analysis. The widespread use of scanning technology has facilitated the implementation of powerful new tools to digitize forensic data, create 3D models and visualize and analyze crash vehicles and environments. The introduction of unmanned aerial systems and standardization of crash data recorders to the crash reconstruction community have enhanced the ability of a crash analyst to visualize and model the components of a crash reconstruction. Because of the technological changes occurring in the industry, many SAE papers have been written to address the validation and use of new tools for collision reconstruction. Collision Reconstruction Methodologies Volumes 1-12 bring together seminal SAE technical papers surrounding advancements in the crash reconstruction field. Topics featured in the series include: • Night Vision Study and Photogrammetry • Vehicle Event Data Recorders • Motorcycle, Heavy Vehicle, Bicycle and Pedestrian Accident Reconstruction The goal is to provide the latest technologies and methodologies being introduced into collision reconstruction - appealing to crash analysts, consultants and safety engineers alike.

Download or read book Vehicle on Shoulder and Crash -- Correlation Or Causation? written by Mei Chen and published by . This book was released on 2020 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study sought to evaluate the relationships between vehicles on shoulder, congestion, and crashes. Three pertinent datasets on interstates were obtained and then integrated using a spatiotemporal approach. The analysis showed that about 36% of the crashes had vehicle on shoulder present in their vicinity, defined as 0.25 miles upstream and downstream of a crash site and 30 minutes before crash occurrence. The percentage increased considerably as spatial/temporal window expanded. In addition, congestion was found to be associated with about 25% of the crashes. The presence of both vehicle on shoulder and congestion was found for 11.7% of the crashes, signifying a high correlation between them and crashes. Based on crash narrative review, 1.8% of all crashes directly involved vehicles on shoulder and 23% of the crashes cited congestion as a contributor. However, there’s little indication in the crash narratives on how vehicles on shoulder contributed to crashes, beyond their direct involvement, or how they contributed to congestion which may led to crashes. Only 6 out of the 512 crashes flagged for review through the keyword search process specified a vehicle on shoulder as a contributor to congestion and subsequent crashes. While a small fraction of crashes were attributed to vehicles on shoulder, these crashes tended to be more severe than average interstate crashes.
