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.

Book Description
This pioneering text provides a holistic approach to decisionmaking in transportation project development and programming, whichcan help transportation professionals to optimize their investmentchoices. The authors present a proven set of methodologies forevaluating transportation projects that ensures that all costs andimpacts are taken into consideration. The text's logical organization gets readers started with asolid foundation in basic principles and then progressively buildson that foundation. Topics covered include: Developing performance measures for evaluation, estimatingtravel demand, and costing transportation projects Performing an economic efficiency evaluation that accounts forsuch factors as travel time, safety, and vehicle operatingcosts Evaluating a project's impact on economic development and landuse as well as its impact on society and culture Assessing a project's environmental impact, including airquality, noise, ecology, water resources, and aesthetics Evaluating alternative projects on the basis of multipleperformance criteria Programming transportation investments so that resources can beoptimally allocated to meet facility-specific and system-widegoals Each chapter begins with basic definitions and concepts followedby a methodology for impact assessment. Relevant legislation isdiscussed and available software for performing evaluations ispresented. At the end of each chapter, readers are providedresources for detailed investigation of particular topics. Theseinclude Internet sites and publications of international anddomestic agencies and research institutions. The authors alsoprovide a companion Web site that offers updates, data foranalysis, and case histories of project evaluation and decisionmaking. Given that billions of dollars are spent each year ontransportation systems in the United States alone, and that thereis a need for thorough and rational evaluation and decision makingfor cost-effective system preservation and improvement, this textshould be on the desks of all transportation planners, engineers,and educators. With exercises in every chapter, this text is anideal coursebook for the subject of transportation systems analysisand evaluation.

Book Description
This document updates and expands the American Association of State Highway and Transportation Officials (AASHTO) User Benefit Analysis for Highways, also known as the Red Book. This AASHTO publication helps state and local transportation planning authorities evaluate the economic benefits of highway improvements. This update incorporates improvements in user-benefit calculation methods and, for the first time, provides guidance for evaluating important non-user impacts of highways. Previous editions of the Red Book provided guidance regarding user benefit measurement only. This update provides a framework for project evaluations that accurately account for both user and non-user benefits. The manual and accompanying CD-ROM provide a valuable resource for people who analyze the benefits and costs of highway projects.

"TRB's National Cooperative Highway Research Program (NCHRP) Report 741: Evaluation of Methodologies for Visual Impact Assessments evaluates visual impact assessment (VIA) procedures, methods, and practices that satisfy or exceed National Environmental Policy Act (NEPA) and other requirements. The report documents VIA methodologies and approaches used in the United States and other countries, describes the decision making framework used to select specific VIA techniques for a given project, includes VIA best practice case studies from state departments of transportation, and highlights promising new developments in the field."--pub. desc.

Book Description
"TRB's National Cooperative Highway Research Program (NCHRP) Report 722: Assessing Highway Tolling and Pricing Options and Impacts provides state departments of transportation (DOTs) and other transportation agencies with a decision-making framework and analytical tools that describe likely impacts on revenue generation and system performance resulting from instituting or modifying user-based fees or tolling on segments of their highway system. Volume 2: Travel Demand Forecasting Tools provides an in-depth examination of the various analytical tools for direct or adapted use that are available to help develop the forecasts of potential revenue, transportation demand, and congestion and system performance based on tolling or pricing changes. Volume 1: Decision-Making Framework includes information on a decision-making framework that may be applied to a variety of scenarios in order to understand the potential impacts of tolling and pricing on the performance of the transportation system, and on the potential to generate revenue to pay for system improvements"--Publication information.
