Algorithms for Routing Vehicles and Their Application to the Paratransit Vehicle Scheduling Problem
"As the demand for paratransit services increases, there is a constant pressure to maintain the quality of service provided to the customers while minimizing the cost of operation: this is especially important as the availability of public funding for paratransit services has been on the decline. Key tasks in accomplishing this objective are efficiently allocating vehicles to service trips and adjusting the schedules of vehicles dynamically in response to calls received by the service providers from the customers on the day of the service."

Use of Performance Measurement to Include Air Quality and Energy Into Mileage-Based User Fees
"This research project is aimed at establishing a framework for levying MBUFs designed to achieve various air quality improvement policy objectives. This research presents the first step toward a pricing framework based on the concept of performance measurement that systematically defines and incorporates potential air quality goals. The process of developing the proposed framework included defining the interactive role of user fees and pricing in roadway transportation operations and identifying air quality performance measures for determining the appropriate vehicle mileage fee price."

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

Fracture Properties and Fatigue Cracking Resistance of Asphalt Binders
"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
"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."
