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

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

Date: April 2012
Creator: Grasley, Zachary Charles & Rahman, Syeda
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."

The design of a comprehensive microsimulator of household vehicle fleet composition, utilization, and evolution

The design of a comprehensive microsimulator of household vehicle fleet composition, utilization, and evolution

Date: January 2012
Creator: Paleti, Rajesh.; Eluru, Naveen; Bhat, R. Chandra; Pendyala, Ram M.; Adler, Thomas J. & Goulias, Konstadinos G.
Description: "The report describes a comprehensive vehicle fleet composition, utilization, and evolution simulator that can be used to forecast household vehicle ownership and mileage by type of vehicle over time. The components of the simulator are developed in this research effort using detailed revealed and stated preference data on household vehicle fleet composition, utilization, and planned transactions collected for a large sample of households in California. Results of the model development effort show that the simulator holds promise as a tool for simulating vehicular choice processes in the context of activity-based travel microsimulation model systems."

Laboratory evaluation of friction loss and compactability of asphalt mixtures

Laboratory evaluation of friction loss and compactability of asphalt mixtures

Date: April 2012
Creator: Kassem, Emad Abdel-Rahman; Masad, Eyad; Awed, Ahmed & Little, Dallas
Description: "This study aimed to develop prediction models for friction loss and laboratory compaction of asphalt mixtures. In addition, the study evaluated the effect of compaction level and compaction method of skid resistance and the internal structure of asphalt mixtures."

Performance measures for metropolitan planning organizations

Performance measures for metropolitan planning organizations

Date: April 2012
Creator: Moore, Devin; Ramni, Tara; Norboge, Nicolas & Turnbull, Katherine
Description: "The aim of this project is to consolidate available knowledge and provide guidance to transportation agencies, specifically MPOs, to help them incorporate performance measurement relating to transportation planning and operations. This research includes a survey of agency practices and agency needs, development of guidance on effective performance measurement and allied issues of strategic planning, goal setting, and data collection."

Getting the parking right for transit-oriented development

Getting the parking right for transit-oriented development

Date: March 2012
Creator: Zhang, Ming.; Mulholland, Katie; Zhang, Jane & Gomez-Sanchez, Ana J.
Description: "The main objective of this study is to report the state-of-the-knowledge on parking regulations and practice influencing the planning, design, and implementation of TOD. The report first offers a narrative review of the published works on TOD-Parking. Based on the review findings it then presents a matrix of best parking practices for TOD."

Fracture properties and fatigue cracking resistance of asphalt binders

Fracture properties and fatigue cracking resistance of asphalt binders

Date: March 2012
Creator: Bhasin, Amit.; Izadi, Anoosha & Motamed, Arash
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."

Potential connected vehicle applications to enhance mobility, safety, and environmental security

Potential connected vehicle applications to enhance mobility, safety, and environmental security

Date: February 2012
Creator: Balke, Kevin N.; Songchitruksa, Praprut. & Zeng, Xiaosi
Description: "Researchers first conducted a comprehensive review of the state-of-the-art connected-vehicle research and technologies. Once researchers had a thorough understanding of the technology, they focused on selecting and developing the near-term practical applications that use connected vehicle technology. The research team then sought expert opinions from the Texas Transportation Institute working group during two brainstorming sessions, which produced two lists of potential applications and prioritized the applications based on deployment feasibility. In particular, a total of five applications were selected for development of the full concept of operations, including two in safety, two in mobility, and one in environmental security. These applications address various problems, including wrong-way driving and unprotected-grade-crossing crashes (safety): work-zone merge efficiency and safety, and freeway speed harmonization (mobility): and slippery pavement-related crashes (environmental security)."

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

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

Date: April 2012
Creator: Chen, Xiaoming & Li, Da
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 at intersection."
