Development of warrants for installation of dual right-turn lanes at signalized intersections

Description: "Right-turn lanes provide space for the deceleration and storage of right-turn vehicle, and separate turning vehicles from through movements. Dual right-turn lanes are increasingly used at urban intersections primarily for two reason: (1) to accommodate high right-turn demands and avoid turn-pocket overflows, and/or (2) to prevent right-turn vehicles that exit from a nearby upstream freeway off-ramp (on the left of the roadway) from abruptly changing too many lanes toward the right-turn lane a… more

Fracture Properties and Fatigue Cracking Resistance of Asphalt Binders

Description: "The main objective of this study was to evaluate the inherent fatigue cracking resistance of asphalt binders in the form of a matrix with rigid particle inclusions. The underlying rational for this approach was to subject the binders to a state of stress that is similar to the one in a full asphalt mixture."

Predicting damage in concrete due to expansive aggregates : modeling to enable sustainable material design

Description: "A poroelastic model is developed that can predict stress and strain distributions and, thus, ostensibly damage likelihood in concrete under freezing conditions caused by aggregates with undesirable combinations of geometry and constitutive properties.Sensitivity of the stress distributions to the aggregate and matrix constitutive parameters are assessed to allow improved concrete design."

Development of reliable pavement models

Description: "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 … more

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

Description: "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

Description: "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)."

Investigate existing Non-Intrusive Inspection (NII) technologies for port cargo inspections

Description: "The goal of this research was to identify the most effective and efficient combination of NII technologies for inspecting cargo arriving at U.S. ports. For this purpose, a discrete-event simulation model was developed to simulate the cargo inspection procedure. By simulating the operations of different combinations of NII technologies, the effectiveness and efficiency of the various combinations were evaluated."
