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
To answer questions being raised by abutting residents and businesses about proposed elevated and/or depressed freeway improvements in the urban and suburban areas of Texas, a four year study has been conducted to estimate the social, economic, and environmental effects of such freeway designs. Eight existing, two under construction, and one approved for construction freeway sections have been studied on a before, during, and after construction basis. The sections selected for study range from being in predominately residential-suburban areas to predominantly commercial-industrial downtown areas. The specific effects of the three types estimated for each study section are as follows: (1) social impacts: population changes, neighborhood accessibility, neighborhood cohesion, and community services; (2) economic impacts: relocation and mitigation costs, business sales, property uses and values, tax revenues, employment and income, and user costs; and (3) environmental impacts: aesthetics, drainage and erosion, noise and air pollution, vibration, and hazardous spills. The literature review and a survey of highway agencies in other states were used to determine the appropriate procedures or models and mitigation measures to implement in estimating the social, economic, and environmental impacts of elevated and depressed freeways. Appropriate study site, local, state, and federal agency data were collected, reduced, and analyzed in the conduct of this study. The findings of the study, presented in five separate reports according to types of effect and summarized in this report, can be used with the recommended estimating procedures to estimate the social, economic, and environmental effects of proposed elevated and depressed freeway projects in urban and suburban areas. Then, transportation planning and designing engineers can use such estimates to prepare environmental statements and conduct public hearings on the recommended grade level of each of the proposed freeway projects. The findings from prior studies indicate that freeway grade level differences in selected measures of social and economic activity are statistically significant. However, these differences are negative or positive, depending largely on various locational factors. The results of this study tend to confirm those findings.

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.
