Download or read book Urban Mobility Report 2004 written by David Schrank and published by DIANE Publishing. This book was released on 2008-10 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Congestion continues to grow in America¿s urban areas. This report presents details on the 2004 trends, findings and what can be done to address the growing transportation problems. Trend data from 1982 to 2002 for 85 urban areas provides both a local view and a national perspective on the growth and extent of traffic congestion. The 2004 Report provides clear evidence that the time for improvements has arrived. Communicating the congestion levels and the need for improvements is a goal of this report. The decisions about which, and how much, improvement to fund will be made at the local level according to a variety of goals, but there are some broad conclusions that can be drawn from this database.

Download or read book Empirical Observation of the Impact of Traffic Oscillations on Freeway Safety written by Christopher Michael Monsere and published by . This book was released on 2010 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Traffic oscillations are typical features of congested traffic flow that are characterized by recurring decelerations followed by accelerations (stop-and-go driving). The negative environmental impacts of these oscillations are widely accepted, but their impact on traffic safety has been debated. This report describes the impact of freeway traffic oscillations on traffic safety. This study employs a matched case-control design using high resolution traffic and crash data from a freeway segment. Traffic conditions prior to each crash were taken as cases, while traffic conditions during the same periods on days without crashes were taken as controls. These were also matched by presence of congestion, geometry and weather. A total of 82 cases and about 80,000 candidate controls were extracted from more than three years of data from 2004 to 2007. Conditional logistic regression models were developed based on the case-control samples. To verify consistency in the results, 20 different sets of controls were randomly extracted from the candidate pool. The results reveal that the standard deviation of speed (thus, oscillations) is a significant variable, with an average odds ratio of about 1.08. This implies that the odds of a (rear-end) crash occurring increases by about 8 percent with an additional unit increase in the standard deviation of speed. The average traffic states prior to crashes were less significant than the speed variations in congestion"--Technical report documentation page.
Download or read book Road Traffic Congestion A Concise Guide written by John C. Falcocchio and published by Springer. This book was released on 2015-03-13 with total page 403 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book on road traffic congestion in cities and suburbs describes congestion problems and shows how they can be relieved. The first part (Chapters 1 - 3) shows how congestion reflects transportation technologies and settlement patterns. The second part (Chapters 4 - 13) describes the causes, characteristics, and consequences of congestion. The third part (Chapters 14 - 23) presents various relief strategies - including supply adaptation and demand mitigation - for nonrecurring and recurring congestion. The last part (Chapter 24) gives general guidelines for congestion relief and provides a general outlook for the future. The book will be useful for a wide audience - including students, practitioners and researchers in a variety of professional endeavors: traffic engineers, transportation planners, public transport specialists, city planners, public administrators, and private enterprises that depend on transportation for their activities.

Download or read book Traffic written by Tom Vanderbilt and published by Vintage Canada. This book was released on 2009-08-11 with total page 418 pages. Available in PDF, EPUB and Kindle. Book excerpt: Driving is a fact of life. We are all spending more and more time on the road, and traffic is an issue we face everyday. This book will make you think about it in a whole new light. We have always had a passion for cars and driving. Now Traffic offers us an exceptionally rich understanding of that passion. Vanderbilt explains why traffic jams form, outlines the unintended consequences of our attempts to engineer safety and even identifies the most common mistakes drivers make in parking lots. Based on exhaustive research and interviews with driving experts and traffic officials around the globe, Traffic gets under the hood of the quotidian activity of driving to uncover the surprisingly complex web of physical, psychological and technical factors that explain how traffic works.

Download or read book Still Stuck in Traffic written by Anthony Downs and published by Rowman & Littlefield. This book was released on 2005-06-22 with total page 484 pages. Available in PDF, EPUB and Kindle. Book excerpt: Congested roads waste commuters' time, cost them money, and degrade the environment. Most Americans agree that traffic congestion is the major problem in their communities—and it only seems to be getting worse. In this revised and expanded edition of his landmark work Stuck in Traffic, Anthony Downs examines the benefits and costs of various anticongestion strategies. Drawing on a significant body of research by transportation experts and land-use planners, he counters environmentalists and road lobbyists alike by explaining why seemingly simple solutions, such as expanding public transit or expanding roads, have unintended consequences that cancel out their apparent advantages. He argues that while there might be some measurable gains from increasing housing densities, most other land-use strategies have little effect. Indeed, the most powerful solutions, including higher gasoline taxes, increased public funding for transit, and highway tolls, are also the least palatable politically. St ill Stuck in Traffic contains new material on the causes of congestion, its dynamics, and its relative incidence in various parts of the country. In clear and realistic terms, Downs seeks to explore why traffic congestion has become part of modern American life and how it can be kept under control.
