DOWNLOAD EBOOKTravel time reliability is frequently cited as an important metric for the trucking community and users of truck freight services. While the travel time reliability for trucking is commonly measured, truck reliability is seldom considered in the benefit-cost evaluation of mobility projects, which under represents the benefits accrued to freight users of the highway system. For NCHRP Project 07-24, WSP was asked to develop an improved framework for the valuation of truck freight reliability. The framework included the methodology, modeling assumptions, analytical techniques, and tools developed in NCHRP Report 824 to assist transportation professionals and decision-makers in the evaluation of proposed roadway infrastructure and operations investments.

DOWNLOAD EBOOK"This report provides a comprehensive analytical framework and related tools that private-sector freight transportation modes and public-sector transportation interests can use to estimate private and public benefits to evaluate potential freight infrastructure investments. Using interviews with transportation planners and an extensive review of prior research and a review of current methods used to assess freight benefits or prioritize improvement projects, the research developed a freight evaluation framework with three main functions: (1) to enhance public planning and decision-making processes regarding freight; (2) to supplement benefit/cost assessment with distributional impact measures; and (3) to advance public-private cooperation. The framework is capable of handling projects that span all of the different modes and able to assess benefits from a variety of project types, including those that improve freight operations, as well as generate more capacity through infrastructure expansion. The research, by developing a practical set of formats for information collection, will support public-private agency discussions by helping all parties understand the wide range of perspectives and interests in potential freight investments."--Pub. desc.

DOWNLOAD EBOOKThe research included an effort to determine the economic value of improvements in travel time reliability by applying options theory from the financial sector. This method is predicated on determining the certainty equivalent of the variability of speed. This innovative approach, briefly summarized in the body of the report and described in an appendix, deserves further exploration despite the lack of consensus from experts about its validity. A prominent part of the report presents a forecast of the year 2030 under alternative assumptions that may influence travel time reliability. The researchers set out three alternative outcomes--optimistic, mediocre, and pessimistic--regarding climate change, economics, and demographics. In addition, they examined a range of technological developments that might affect reliability. To paint a picture of the future, they prepared a concept of operations for the year 2030.

DOWNLOAD EBOOKThis primer provides a foundation for understanding the role of economic analysis in highway decision making. It is oriented toward state and local officials who have responsibility for assuring that limited resources get targeted to their best uses and who must publicly account for their decisions. Economic analysis is presented as an integral component of a comprehensive infrastructure management methodology that takes a long-term view of infrastructure performance and cost. The primer encompasses a full range of economic issues, including economic fundamentals, life-cycle cost analysis, benefit-cost analysis, forecasting traffic for benefit calculations, risk analysis and economic impact analysis.

DOWNLOAD EBOOKThis monograph presents a simple, innovative approach for the measurement and short-term prediction of highway travel times based on the fusion of inductive loop detector and toll ticket data. The methodology is generic and not technologically captive, allowing it to be easily generalized for other equivalent types of data. The book shows how Bayesian analysis can be used to obtain fused estimates that are more reliable than the original inputs, overcoming some of the drawbacks of travel-time estimations based on unique data sources. The developed methodology adds value and obtains the maximum (in terms of travel time estimation) from the available data, without recurrent and costly requirements for additional data. The application of the algorithms to empirical testing in the AP-7 toll highway in Barcelona proves that it is possible to develop an accurate real-time, travel-time information system on closed-toll highways with the existing surveillance equipment, suggesting that highway operators might provide their customers with such an added value with little additional investment in technology.
