Scoping is the process of developing a project's objectives, need, preliminary cost estimate, and preliminary schedule based on a recognized need that the project is intended to address. This study (INDOT/JTRP SPR 3944) was launched by the Indiana Department of Transportation (INDOT)/Joint Transportation Program (JTRP) to develop a synthesis of scoping processes in different State Highway Agencies (SHA). The study was conducted using a qualitative exploratory approach focusing on the review of project scoping practices across different SHAs. Focused interviews with personnel from State Highway Agencies (SHA) along with the review of documents gathered during the literature search and resources provided by SHAs were the avenues used for data collection in the study.The study focused on eleven themes for the assessment of project scoping procedures: (1) primary entity with responsibility for scoping projects, (2) timeline for scoping activities, (3) functional groups within the State Highway Agency involved in scoping, (4) cost estimation procedures, (5) application of Context Sensitive Solutions (CSS), (6) addressing maintenance needs, (7) methods of assessing scope creep, (8) tracking the quality and effectiveness of scoping processes, (9) environmental consideration in scoping processes, (10) data collection and data sharing, and (11) scoping practices which have evolved/benefited the State Highway Agency. The report presents key findings of the study and provides suggestions for further investigation by INDOT.

TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 348: Improving the Safety of Older Road Users examines programs and policies in place across the country to improve the safety and mobility of older road users. The report documents a range of strategies and related programs under way in roadway engineering, driver licensing, public information and education, and enforcement and adjudication.
