Nchrp Synthesis 391

"TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 391: Public Sector Decision Making for Public-Private Partnerships examines information designed to evaluate the benefits and risks associated with allowing the private sector to have a greater role in financing and developing highway infrastructure"--Publisher's description.

Transportation asset management delivers efficient and cost-effective investment decisions to support transportation infrastructure and system usage performance measured in economic, social, health, and environmental terms. It can be applied at national, state, and local levels. This distinctive book addresses asset management for multimodal transportation, taking account of system component interdependency, integration, and risk and uncertainty. It sets out rigorous quantitative and qualitative methods for addressing system goals, performance measures, and needs; data collection and management; performance modeling; project evaluation, selection, and trade-off analysis; innovative financing; and institutional issues. It applies as easily to static traffic and time-dependent or dynamic traffic which exists on a more local level. It is written for transportation planners, engineers, and academia, as well as a growing number of graduate students taking transportation asset management courses.

TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 293: Reducing and Mitigating Impacts of Lane Occupancy During Construction and Maintenance describes the current state of the practice for reducing and mitigating the impacts of lane occupancy during construction and maintenance.

This synthesis will be of interest to pavement construction, maintenance, design, and materials engineers; pavement contractors; and others interested in the use of open-graded friction course (OGFC) mixes. It describes the current state of the practice on the use of OGFC mixes, including information regarding design, materials, construction, maintenance, and rehabilitation strategies. Alternative treatments to traditional OGFC are also identified and discussed. Information was collected by surveying U.S. and Canadian transportation agencies and by conducting a literature search to gather additional insight into North American and European practices. This TRB report describes the recent performance of North American OGFC mixes and European porous asphalt by identifying benefits and stress indicators. A new generation of OGFC mixes has evolved over the last 5 years with changes that have been reported to dramatically improve performance. This synthesis describes new materials and design methods being used, as well as the applicability of the new generation of open-graded mixtures to North American use.

"In The Road to Renewal: Private Investment in U.S. Transportation Infrastructure, R. Richard Geddes surveys the current state of the American transportation system and finds that, like the roads themselves, the existing policy approach is in desperate need of repair. Drawing on the basic economic principles behind supply, demand, competition, and incentives, Geddes argues that a shift toward increased use of public-private partnerships (PPPs)--contractual agreements between public agencies and private parties that allow private participation in the design, construction, operation, and delivery of transportation facilities--could significantly improve the quality of America's transportation infrastructure. By learning to see themselves as customers and investors--rather than mere users--of roads and highways, Americans should expect to receive a reasonable return on their investment: thorough, effective maintenance of America's transportation infrastructure. The Road to Renewal shows how incorporating increased private participation can halt the deterioration of America's transportation system and become the foundation for a safer, more efficient transportation future."--P.
