Congress asked the committee to make recommendations on the \u201cfeatures, standards, capacity needs, application of technologies, and intergovernmental roles to upgrade the Interstate System\u201d and to advise on any changes in law and resources required to further the recommended actions. The report of the study committee suggests a path forward to meet the growing and shifting demands of the 21st century.The prospect of an aging and worn Interstate System that operates unreliably is concerning in the face of a vehicle fleet that continues to transform as the 21st century progresses and the vulnerabilities due to climate change place new demands on the country\u2019s transportation infrastructure. Recent combined state and federal capital spending on the Interstates has been about $20\u2013$25 billion per year. The estimates in this study suggest this level of spending is too low and that $45\u2013$70 billion annually over the next 20 years will be needed to undertake the long-deferred rebuilding of pavements and bridges and to accommodate and manage growing user demand. This estimated investment is incomplete because it omits the spending that will be required to meet other challenges such as boosting the system\u2019s resilience and expanding its geographic coverage.The committee recommends that Congress legislate an Interstate Highway System Renewal and Modernization Program (RAMP). This program should focus on reconstructing deteriorated pavements, including their foundations, and bridge infrastructure; adding physical capacity and operations and demand management capabilities where needed; and increasing the system\u2019s resilience. The report explores ways to pay for this program, including lifting the ban on tolling of existing general-purpose Interstate highways and increasing the federal fuel tax to a level commensurate with the federal share of the required RAMP investment.View the videos, recorded webcast, graphics, summary booklet, press release, and highlights page at interstate.trb.org.

The guidebook illustrates the effort needed to develop a robust cost estimate and then manage to a baseline budget and scope throughout the project delivery cycle. The guidebook is applicable to a range of project types and is scalable in its ability to accommodate projects of varying complexity.Increasing or otherwise changing the scope of a project to improve facility performance is a common source of cost increases and schedule delays, as is failure to adequately consider project impacts on utilities, communities, or the environment. Industrial and commercial building construction sectors have experienced similar problems with construction project scope growth, cost increases, and time delays that occur after a project has been authorized for detailed design and construction.Recent research in these sectors has produced a structured and systematic process to help owners meet project cost and schedule objectives by defining a project to a suitable level of development prior to authorization of detailed design. Statistical evidence indicates that earlier and more detailed scoping efforts can reduce total design and construction cost by as much as 20%, and shorten total design and construction schedules by as much as 39%. Such scoping processes, with supporting indices and tools to calibrate the level of scoping effort required to achieve these results, have become standard procedures that many private U.S. corporations use in their capital facilities development efforts. With modifications, these processes and tools may be transferable to the transportation industry.", url = "https://nap.nationalacademies.org/catalog/23398/effective-project-scoping-practices-to-improve-on-time-and-on-budget-delivery-of-highway-projects", year = 2016, publisher = "The National Academies Press", address = "Washington, DC" }
