Download or read book Operational Impacts of Median Width on Larger Vehicles written by Douglas W. Harwood and published by Transportation Research Board. This book was released on 2000 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: This synthesis report will be of interest to officials and staff of municipal, regional, and statewide transportation agencies responsible for roadway design and traffic control. It will be of special interest to those concerned with intersections and driveways on divided highways where larger vehicles encounter narrow medians. It will also be of interest to other professionals who interact with these agencies to mitigate such problems. This report presents state-of-the-practice information about current median design policies and practices, describes the traffic operational and safety problems encountered in designing for larger vehicles at divided highway intersections, and identifies alternative improvement techniques that can be used in new construction or reconstruction projects to avoid introducing traffic operational and safety problems. This TRB report focuses on 10 alternative cross sections widely used on arterial highways in urban, suburban, and rural environment.

Download or read book Distributional Effects of Environmental and Energy Policy written by Don Fullerton and published by Routledge. This book was released on 2017-05-15 with total page 397 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many effects of environmental and energy policy are likely to disproportionately burden those with low income. First, it raises the price of fossil-fuel-intensive products that constitute a high fraction of low-income budgets (like gasoline, heating fuel and electricity). Second, the handout of pollution permits to firms provides value to those who own them. Third, low-income individuals may place more value on food and shelter than on improvements in environmental quality, so high-income individuals may get the most benefit of pollution abatement. Fourth, air quality improvements may raise the value of houses owned by landlords, rather than helping renters. These effects might all hurt the poor more than the rich. This book brings together the seminal economics literature that studies whether these fears are valid and whether anything can be done about them.

Available in PDF, EPUB and Kindle. Book excerpt: In part I, observations on the traffic stream made under two intensities of artifical illumination and under daylight conditions are studied along with an analysis of the accident rate under day and night conditions over a 5 year period. Part II centers upon the individual driver and his performance in controlling his vehicle under different nighttime illumination levels. The subjects drove an instrumented vehicle equipped with an oscillograph recorder and sensors for velocity, steering, and gas pedal movements. Part III deals with the instrumentation of the vehicle. Part IV pertains to the area of driver apprehension, the effects of illumination change upon visual phenomena and driver responses and the effects upon traffic flow, driver behavior, and accidents.
Download or read book A Guide for Achieving Flexibility in Highway Design written by and published by AASHTO. This book was released on 2004 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: Context-sensitive solutions (CSS) reflect the need to consider highway projects as more than just transportation facilities. Depending on how highway projects are integrated into the community, they can have far-reaching impacts beyond their traffic or transportation function. CSS is a comprehensive process that brings stakeholders together in a positive, proactive environment to develop projects that not only meet transportation needs, but also improve or enhance the community. Achieving a flexible, context-sensitive design solution requires designers to fully understand the reasons behind the processes, design values, and design procedures that are used. This AASHTO Guide shows highway designers how to think flexibly, how to recognize the many choices and options they have, and how to arrive at the best solution for the particular situation or context. It also strives to emphasize that flexible design does not necessarily entail a fundamentally new design process, but that it can be integrated into the existing transportation culture. This publication represents a major step toward institutionalizing CSS into state transportation departments and other agencies charged with transportation project development.
Download or read book The Handbook of Research Synthesis and Meta Analysis written by Harris Cooper and published by Russell Sage Foundation. This book was released on 2009-02-05 with total page 632 pages. Available in PDF, EPUB and Kindle. Book excerpt: Praise for the first edition: "The Handbook is a comprehensive treatment of literature synthesis and provides practical advice for anyone deep in the throes of, just teetering on the brink of, or attempting to decipher a meta-analysis. Given the expanding application and importance of literature synthesis, understanding both its strengths and weaknesses is essential for its practitioners and consumers. This volume is a good beginning for those who wish to gain that understanding." —Chance "Meta-analysis, as the statistical analysis of a large collection of results from individual studies is called, has now achieved a status of respectability in medicine. This respectability, when combined with the slight hint of mystique that sometimes surrounds meta-analysis, ensures that results of studies that use it are treated with the respect they deserve....The Handbook of Research Synthesis is one of the most important publications in this subject both as a definitive reference book and a practical manual."—British Medical Journal When the first edition of The Handbook of Research Synthesis was published in 1994, it quickly became the definitive reference for researchers conducting meta-analyses of existing research in both the social and biological sciences. In this fully revised second edition, editors Harris Cooper, Larry Hedges, and Jeff Valentine present updated versions of the Handbook's classic chapters, as well as entirely new sections reporting on the most recent, cutting-edge developments in the field. Research synthesis is the practice of systematically distilling and integrating data from a variety of sources in order to draw more reliable conclusions about a given question or topic. The Handbook of Research Synthesis and Meta-Analysis draws upon years of groundbreaking advances that have transformed research synthesis from a narrative craft into an important scientific process in its own right. Cooper, Hedges, and Valentine have assembled leading authorities in the field to guide the reader through every stage of the research synthesis process—problem formulation, literature search and evaluation, statistical integration, and report preparation. The Handbook of Research Synthesis and Meta-Analysis incorporates state-of-the-art techniques from all quantitative synthesis traditions. Distilling a vast technical literature and many informal sources, the Handbook provides a portfolio of the most effective solutions to the problems of quantitative data integration. Among the statistical issues addressed by the authors are the synthesis of non-independent data sets, fixed and random effects methods, the performance of sensitivity analyses and model assessments, and the problem of missing data. The Handbook of Research Synthesis and Meta-Analysis also provides a rich treatment of the non-statistical aspects of research synthesis. Topics include searching the literature, and developing schemes for gathering information from study reports. Those engaged in research synthesis will also find useful advice on how tables, graphs, and narration can be used to provide the most meaningful communication of the results of research synthesis. In addition, the editors address the potentials and limitations of research synthesis, and its future directions. The past decade has been a period of enormous growth in the field of research synthesis. The second edition Handbook thoroughly revises original chapters to assure that the volume remains the most authoritative source of information for researchers undertaking meta-analysis today. In response to the increasing use of research synthesis in the formation of public policy, the second edition includes a new chapter on both the strengths and limitations of research synthesis in policy debates
