This report documents an evaluation of Federal Highway Administration’s (FHWA) Research and Technology Program’s activities on the implementation of the Eco-Logical approach by State transportation departments and metropolitan planning organization recipients of FHWA Eco-Logical funding. The evaluation team collected information on FHWA’s efforts to disseminate information to stakeholders, the extent to which stakeholders have adopted the Eco-Logical approach, and stakeholder-identified processes and environmental impacts obtained by agencies implementing the Eco-Logical approach. Data collected from literature reviews and stakeholder interviews (see main report for specific reference information) suggest that FHWA has consistently recognized the value of demonstrating its commitment to the Eco-Logical approach by providing funding and technical assistance to its stakeholders and encouraging practitioners to share results with their peers. FHWA research and funding has enabled its recipients to adopt the Eco-Logical approach sooner and more comprehensively. Funding recipients are building relationships with partners, sharing and using data in better ways, and incorporating information gathered to inform project prioritization and to develop integrated transportation plans. Most recipients focused their efforts on completing earlier planning-level steps and stages of the Eco-Logical approach. Few recipients identified, tracked, or quantified impacts related to project delivery or environmental mitigation. FHWA, partners, and stakeholders demonstrated a commitment to the Eco-Logical approach. Stakeholders adopted the Eco-Logical approach by building relationships, sharing and using data, integrating plans, and prioritizing project selection and mitigation.
TRB Special Report 256 - Managing Technology Transfer: A Strategy for the Federal Highway Administration addresses how the U.S. Department of Transportation's Federal Highway Administration selects research products for technology transfer and transfers those products to the highway industry, in particular the state and local agencies that own, operate, and maintain the nation’s highways.
As part of the Federal Highway Administration’s (FHWA) Research and Technology Program evaluation, this report documents the findings of a summative evaluation of various adaptive signal control technology (ASCT) research and outreach activities conducted by FHWA over the course of more than 20 yr. The evaluation considers the ways in which FHWA’s investment in ASCT research and related outreach activities have influenced the development and deployment of these technologies. The evaluation also addresses the short-term impacts of ASCT deployments, including reduced traffic congestion and delays. Due to the extended timeline of the program, the research and outreach activities were chronologically categorized into three distinct phases, and each was evaluated on its influence on ASCT development and deployment. This report also identifies challenges and lessons learned that may be applied to further intelligent transportation systems research.
TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 328: State Product Evaluation Programs examines the general use of evaluation programs within state departments of transportation (including the use of state specifications, and laboratory and field testing results), the national programs that exist to support the integration of new products and technologies into practice, and the general issues associated with conducting objective evaluations of new products and implementation of approved products.
