This technical memorandum summarizes the analysis performed in evaluating Long-Life Pavement Rehabilitation Strategies (LLPRS) cost. This study is part of the effort to develop an Integrated Pavement Strategy Decision Support System to allow engineers to analyze efficient allocation of financial...

The literature on the modeling of diffusion of technologies typically uses historical data to calibrate a model. For cases where data on the diffusion of comparable technologies are not available and where high multi-sector stakes are involved, models that use more specific information may be...

Given the dominance of power plant emissions of greenhouse gases, and the growing worldwide interest in CO2 capture and storage (CCS) as a potential climate change mitigation option, the expected future cost of power plants with CO2 capture is of significant interest. Reductions in the cost of...

This report presents the results of the study, "Pilot Project for Fixed Segmentation of the Pavement Network." The goal of this pilot project was to study a small sample of the California Department of Transportation (Caltrans) network to determine the feasibility of expanding the pilot approach...

Few integrated analysis models examine significant U.S. transportation greenhouse gas emission reductions within an integratedenergysystem.Ouranalysis, usingabottom-upMARKet ALocation (MARKAL) model, found that stringent systemwide CO2 reduction targets will be required to achieve significant...

A comprehensive study on full-depth reclamation (FDR) of pavements with foamed asphalt has been completed for the California Department of Transportation by the University of California Pavement Research Center. A literature review revealed that very little research had been carried out on the...

Human activities associated with the production and use of energy and materials can pollute the air and water. Since the late 1960s concern about regional and local air pollution has led to the adoption of environmental laws and regulations regarding major polluting human activities, such as...

There is growing interest in hydrogen as a transportation fuel in California. Plans are underway to construct a �Hydrogen Highway� network of stations across the state to stimulate fuel cell vehicle deployment. One of the key challenges however in the planning and financing of this...

Using transportation and other social science data examples, and focusing in depth on telecommuting, we demonstrate that definitions, measurement instruments, sampling and sometimes vested interests affect the quality and utility even of seemingly objective and "measurable" data. Little...

Transportation is a major contributor of carbon dioxide (CO2) and other greenhouse gas emissions from human activity. It accounts for approximately 14% of total anthropogenic emissions globally and about 27% in the United States. Growing concern regarding the impacts of climate change and...
