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.

"The objectives of the RETA [regional technical assistance project], a study based on a literature and project review and on field research in three Asian countries [People's Republic of China, Thailand and India], were to enhance current understanding of how transport and energy infrastructure contribute to poverty reduction, to fill knowledge gaps, and to identify lessons learned and good practices."--P. 1.

Book Description
This synthesis will be of interest to highway environmental specialists (particularly those concerned with assessing social and economic impacts), design engineers, planners, utility managers, and others responsible for the planning, design, and implementation of highway-widening improvements. Information is presented on the reasons for highway-widening projects, the nature of the projects, and the methods and practices for application of analytical techniques used to measure the potential or actual impacts of the projects on people and the physical environment. Mitigation measures are also discussed. This report of the Transportation Research Board describes the most recent widening projects as reported by states or other transportation agencies, as well as the most frequently encountered issues in highway widening. Selected examples of widening projects are included, as is some recognition of the need for additional information and research in the areas of social and economic impact measurement.

Book Description
This synthesis report will be of interest to DOT administrators, supervisors, and staff, as well as to the consultants working with them in assessing the economic development impacts of existing or proposed transportation investments. Metropolitan Planning Organization regional and local staffs might also find it informative. It is intended to help practicing planners become aware of the range of methods and analysis techniques available, organized by the different categories of agency needs, to address different types of planning, policy, and research needs. This synthesis summarizes the current state of the practice by means of a survey of transportation planning agencies in the United States, Canada, and the United Kingdom. This report provides reviews of the analysis methods used in recent project and program evaluation reports of these agencies, in addition to a bibliography of economic literature and guides.

Book Description
The focus on results in development agencies has led to increased focus on impact evaluation to demonstrate the effectiveness of development programmes. This book illustrates the broad range of methods available for counterfactual analysis of infrastructure programmes such as establishment, rehabilitation and maintenance of roads, water supply and electrical power plants and grids. Understanding the impact of interventions requires understanding of the context in which the intervention takes place and the channels through which it is expected to occur. For infrastructure interventions it is particularly important to identify the links between the input and the outcomes and impacts because the well-being of people, the ultimate impact, does not change directly as a consequence of the intervention. Therefore impact evaluation of infrastructure programmes typically requires mixing both quantitative and qualitative approaches as illustrated in many of the contribution to this edited volume. This book was originally published as a special issue of the Journal of Development Effectiveness.
