Assessing and Managing the Ecological Impacts of Paved Roads


Book Description

All phases of road developmentâ€"from construction and use by vehicles to maintenanceâ€"affect physical and chemical soil conditions, water flow, and air and water quality, as well as plants and animals. Roads and traffic can alter wildlife habitat, cause vehicle-related mortality, impede animal migration, and disperse nonnative pest species of plants and animals. Integrating environmental considerations into all phases of transportation is an important, evolving process. The increasing awareness of environmental issues has made road development more complex and controversial. Over the past two decades, the Federal Highway Administration and state transportation agencies have increasingly recognized the importance of the effects of transportation on the natural environment. This report provides guidance on ways to reconcile the different goals of road development and environmental conservation. It identifies the ecological effects of roads that can be evaluated in the planning, design, construction, and maintenance of roads and offers several recommendations to help better understand and manage ecological impacts of paved roads.




Interregional Travel


Book Description

TRB Special Report 320: Interregional Travel: A New Perspective for Policy Making examines the demand for and supply of interregional transportation in the United States. Major additions to transportation infrastructure, including high-speed rail, are being considered for some of the country’s most heavily traveled 100- to 500-mile corridors. The availability and use of the automobile, airplane, and train for interregional travel are reviewed along with the rejuvenated intercity bus. U.S. interregional corridors and transportation options are contrasted with those in Japan and Europe, where substantial investments have been made in passenger rail. Public investments in new, long-lived transportation infrastructure can be risky because of uncertainty about future demand and the development of new technologies and competing transportation services. Decisionmakers in interregional corridors face the added challenge of having to coordinate investments across multiple jurisdictions. The report recommends actions to reduce this uncertainty and create stronger institutional means for developing the country’s interregional corridors. TR News 303 features an article on Interregional Travel: A New Perspective for Policy Making. A video about the research is now available: At the 2016 TRB Annual Meeting, January 10-14, 2016, a session entitled Interregional Travel: Policymaking from a New Perspective was webcast live. These videos provide an overview of various components of the project. Introduction: Part 1: Overview of Project Scope Part 2: Data and Information Needs Part 3: Intercity Bus Operations Question and Answer Session Presenters: Tom Deen Nancy McGuckin Joe Schweiterman Moderated by: Martin Wachs

Transportation Planning Handbook


Book Description

A multi-disciplinary approach to transportation planning fundamentals The Transportation Planning Handbook is a comprehensive, practice-oriented reference that presents the fundamental concepts of transportation planning alongside proven techniques. This new fourth edition is more strongly focused on serving the needs of all users, the role of safety in the planning process, and transportation planning in the context of societal concerns, including the development of more sustainable transportation solutions. The content structure has been redesigned with a new format that promotes a more functionally driven multimodal approach to planning, design, and implementation, including guidance toward the latest tools and technology. The material has been updated to reflect the latest changes to major transportation resources such as the HCM, MUTCD, HSM, and more, including the most current ADA accessibility regulations. Transportation planning has historically followed the rational planning model of defining objectives, identifying problems, generating and evaluating alternatives, and developing plans. Planners are increasingly expected to adopt a more multi-disciplinary approach, especially in light of the rising importance of sustainability and environmental concerns. This book presents the fundamentals of transportation planning in a multidisciplinary context, giving readers a practical reference for day-to-day answers. Serve the needs of all users Incorporate safety into the planning process Examine the latest transportation planning software packages Get up to date on the latest standards, recommendations, and codes Developed by The Institute of Transportation Engineers, this book is the culmination of over seventy years of transportation planning solutions, fully updated to reflect the needs of a changing society. For a comprehensive guide with practical answers, The Transportation Planning Handbook is an essential reference.
