This report reflects information obtained from a broad range of sources, including a survey of more than 350 federal and state transportation and environmental agencies, academic institutions, and other organisations having interest and expertise in transportation project planning and development. From this data collection, the authors have provided a thorough synthesis of agency regulation, case law, published literature, environmental impact statement content, and practitioner experience and perspective leading to a typology of "indirect effects." The report also includes a framework for identifying and analysing indirect effects of proposed transportation projects in order to provide planners and practitioners the ability to integrate indirect effects assessment into ongoing evaluation processes. Finally, the authors have identified appropriate tools and techniques which of the indirect effects of a proposed transportation project warrant detailed analysis and for carrying out those analysis.
