Development of reliable pavement models (open access)

Development of reliable pavement models

"The current report proposes a framework for estimating the reliability of a given pavement structure as analyzed by the Mechanistic-Empirical Pavement Design Guide (MEPDG). The methodology proposes using a previously fit response surface, in place of the time-demanding implicit limit state functions used within the MEPDG, in combination with an analytical approach to estimating reliability using First-Order and Second-Order Reliability Methods (FORM and SORM). Additionally, in order to assess the accuracy of the FORM and SORM reliability estimates, Monte Carlo simulations are also performed."

Managed lane travelers: do they pay for travel as they claimed they would? (open access)

Managed lane travelers: do they pay for travel as they claimed they would?

"This study examined if travelers are paying for travel on managed lanes (MLs) as they indicated that they would in a 2008 survey. To achieve the objectives, an Internet-based stated preferences (SP) survey of Houston's Katy Freeway travelers was conducted in 2010. Three survey design methodologies-Db-efficent, random level generation, and adaptive random-were tested in this survey."

The light-duty-vehicle fleet's evolution: anticipating Plug-In-Electric-Vehicle adoption and greenhouse gas emissions across the U.S. fleet

"The first part of this report relies on stated and revealed preference survey results across a sample of U.S. households to first ascertain vehicle acquisition, disposal, and use patterns, and then simulate these for a synthetic population over time. The second part of this report relies on data from the U.S. Consumer Expenditure Survey (CEX) to estimate the welfare impacts of carbon taxes and household-level capping of emission (with carbon-credit trading allowed)."

Development of a Special Topics Course on Civil Engineering Project Finance for the Zachry Department of Civil Engineering of Texas A&M University (open access)

Development of a Special Topics Course on Civil Engineering Project Finance for the Zachry Department of Civil Engineering of Texas A&M University

A project finance course integrated into the core curriculum for graduate civil engineering students. Even fewer programs treat project finance as a truly interdisciplinary topic. In fact, the topic of project finance often constitutes only a small part of the structured finance curricula. The purpose of this project was to bridge this gap by developing educational and teaching materials for an interdisciplinary course in project finance. This course communicates the implications of financial decisions on engineering choices and vice versa. The course is directed toward graduate students at the Master of Science level to better prepare them to deal with real-world transportation financing.
