In March 1998, the Federal Highway Administration (FHWA) Office of Natural Environment, released the FHWA Traffic Noise Model (FHWA TNM) Version 1.0, a state-of-the-art computer program for highway traffic noise prediction and analysis. Since then, the FHWA, with assistance from the Volpe Center Acoustics Facility (Volpe Center) and Foliage Software Systems (FSS), have released updates of TNM (Versions 1.0a, and 1.0b) in March 1999 and August 1999, respectively. In support of the FHWA and the California Department of Transportation, the Volpe Center and FSS released Version 1.1 in September 2000. TNM 2.0 is the latest release of the TNM software. Two companion reports were released with TNM Version 1.0, a Technical Manual that describes the acoustics within TNM and a User's Guide. In addition, prior to TNM release, a data report was published that describes the vehicle noise-emissions data base within TNM. This document is an addendum to the FHWA TNM Version 1.0 User's Guide. It details the enhancements in the program up to and including Version 2.0.

The objective of this scanning tour and document was to gather information from European transportation ministries and lighting professionals regarding cutting-edge research and technologies in highway and roadway lighting systems, including tunnel illumination, sign lighting, and all methods used to design roadway lighting systems.

World Bank Technical Paper No. 376. Roads are agents of change and can be responsible for both benefits and damage to the existing balance between people and their environment. This handbook examines specific road projects ranging from minor rehabilitation and maintenance activities on existing roads to major works on new alignments. It provides a description of practical methods for designing and executing effective environmental assessments that are useful to those who are involved in various aspects of road projects, from planning to construction to maintenance.

This volume, the first to result from the Diebold Institute Information-Based Infrastructure Project, explores the links between business and government in the development of intelligent transportation systems (ITS) technology. The work focuses on road and vehicular infrastructures, comparing those of the U.S., Europe, and Japan, and the roles that ITS can play in solving major current and anticipated future transportational problems. Special attention is given to environmental and economic concerns.

The world's infrastructure requires refurbishing, but it especially requires rethinking. The computer has transformed business enterprises and now information technology can change our environment. This book explores the benefits and how to achieve them through the use of intelligent transportation systems (ITS). The implementation of ITS will potentially lead to individual drivers, fleet operators, and public transit users saving vast amounts of journey time and fuel, to a significant reduction in pollution and to improved road safety. The Japanese are ahead of the U.S. and Europe in the area of intelligent transportation systems, using position location devices, and electronic maps.

Most look at this development as one that helps speed passenger cars, but this book details the economics which point to the technology being equally good for speeding trucks and easing the movement of freight. Traffic avoidance is only part of the problem although route guidance is helpful. Financing of projects in ITS is an important area for innovation and ITS could be a source of revenue to municipalities rather than an expense.

The new edition includes: - Issues surrounding provision for charging hybrid and electrically powered vehicles - a topic as yet poorly addressed in the literature. - Optimum entry and exit locations that affect layout. - 50% more drawings - including scale drawings that can be used as templates in the layout design process.

How is it that nearly 90 percent of the Texan population currently lives in metropolitan regions, but many Texans still embrace and promote a vision of their state's nineteenth-century rural identity? This is one of the questions the editors and contributors to Lone Star Suburbs confront. One answer, they contend, may be the long shadow cast by a Texas myth that has served the dominant culture while marginalizing those on the fringes. Another may be the criticism suburbia has endured for undermining the very romantic individuality that the Texas myth celebrates. From the 1950s to the present, cultural critics have derided suburbs as landscapes of sameness and conformity. Only recently have historians begun to document the multidimensional industrial and ethnic aspects of suburban life as well as the development of multifamily housing, services, and leisure facilities. In Lone Star Suburbs, urban historian Paul J. P. Sandul, Texas historian M. Scott Sosebee, and ten contributors move the discussion of suburbia well beyond the stereotype of endless blocks of white middle-class neighborhoods and fill a gap in our knowledge of the Lone Star State. This collection supports the claim that Texas is not only primarily suburban but also the most representative example of this urban form in the United States. Essays consider transportation infrastructure, urban planning, and professional sports as they relate to the suburban ideal; the experiences of African Americans, Asian Americans, and Latinos in Texas metropolitan areas; and the environmental consequences of suburbanization in the state. Texas is no longer the bastion of rural life in the United States but now - for better or worse - represents the leading edge of suburban living. This important book offers a first step in coming to grips with that reality.

Schwerpunkt des Buches bildet die Auseinandersetzung mit den sich wechselseitig beeinflussenden Aspekten von Mobilitat, Verkehr und Raumnutzung. Neben einer Beschaftigung mit den fur das Mobilitatsverhalten bzw. Verkehr grundlegenden menschlichen Bedurfnissen wird vor allem auch auf die speziellen topografischen Gegebenheiten in Gebirgsraumen eingegangen. Diese regionalspezifischen Aspekte erfordern zusammen mit sich standig andernden globalen Rahmenbedingungen eine uber die traditionellen Modelle der Verkehrs- und Regionalwissenschaft hinausgehende interdisziplinare Sichtweise. Der in diesem Buch beschriebene Modellansatz stellt eine generelle Grundlage zur Entwicklung und auch Evaluierung zukunftsfahiger Planungsstrategien dar.

About 93 trains a day on average crossed into the continental United States from Canada and Mexico in 2014, according to U.S. Department of Transportation's (DOT) Bureau of Transportation Statistics (BTS). Trains enter and leave the United States through 30 port of entries (POEs) -- 23 on the northern border and 7 on the southern border. Although international freight rail plays an important role in U.S. economic and trade interests, the movement of rail through U.S. communities at the border can result in blocked highway-rail grade crossings and vehicle traffic congestion. This book describes the factors that affect the movement of freight rail and the actions taken by federal agencies and others to expedite freight rail in selected POEs; and examines what is known about the impacts of freight rail operations on highway-rail grade crossings in POE communities. Moreover, the book addresses recent changes in U.S. rail and truck freight flows and the extent to which related traffic congestion is reported to impact communities; and the extent to which DOTs efforts to implement Moving Ahead for Progress in the 21st Century Act (MAP-21) address freight-related traffic congestion in communities.

Federal spending on highways totaled $46 billion in 2014, roughly a quarter of total public spending on highways. About 95 percent of that amount was spent for the construction of highways or for their improvement, expansion, and major repair, and the remainder was spent for operation and maintenance. Recently, two factors have combined to highlight the importance of making each dollar spent on federal highway programs more productive economically. First, the federal governments main source of funds for highways -- gasoline tax revenues dedicated to the Highway Trust Fund -- has been insufficient to pay for federal spending on highways. Since 2008, lawmakers have transferred about $143 billion from other sources to maintain a positive balance in the trust fund. Second, adjusted for changes in construction costs, total federal spending on highways buys less now than at any time since the early 1990s. This book discusses approaches to making federal highway spending more productive, as well as the status of the Highway Trust Fund and options for paying for highway spending.

This book may be of use to traffic engineers and researchers who are concerned with the conspicuity of traffic signs. The Manual on Uniform Traffic Control Devices advises that, "Signs should be placed on the right side of the roadway where they are easily recognised and understood by road users". Guidance is provided on the spacing and prioritisation of signs, and in some conditions, additional steps may be needed to ensure that signs are conspicuous. This book also provides federal regulations that have been put in place to ensure that traffic signs are visible at night, and discusses impacts on state and local agencies of maintaining traffic sign retroreflectivity.

In diesem essential wendet sich Joern Pachl an Fachleute des deutschen Bahnbetriebs, die sich uber charakteristische Unterschiede auslandischer Betriebsverfahren gegenuber den im deutschen Bahnwesen ublichen Grundsatzen informieren moechten. Obwohl die technischen Grundzuge von Eisenbahnen uberall gleich sind, zeigt der Autor, dass die Betriebsverfahren in erheblichem Mass differieren. Die Unterschiede liegen nicht im Detail, sondern betreffen selbst grundlegende Definitionen im System Bahn. Da im Rahmen dieser kompakten Darstellung keine Detailbeschreibungen einzelner Lander moeglich sind, konzentriert sich der Autor auf Bereiche mit besonders relevanten Unterschieden zum deutschen Bahnbetrieb, die an typischen Beispielen demonstriert werden. Neben einigen kleineren Erganzungen und Prazisierungen wurde in der zweiten Auflage die Anschaulichkeit der Abbildungen durch UEbergang zu farbigen Darstellungen deutlich erhoeht.
