Megaregion Freight Planning: A Synopsis (open access)

Megaregion Freight Planning: A Synopsis

"Megaregion interest has grown strongly in the last decade and is now seen be a growing number of planners as offering effective contributions to problems such as modal congestion, development disparity, and air pollution that individual metropolitan areas or cities cannot resolve individually. Megaregion planning presents an alternative way of mitigating metropolitan problems of large-scale transportation systems, green infrastructure, and economic development and has attracted a number of transportation advocates since 2000."

Algorithms for Routing Vehicles and Their Application to the Paratransit Vehicle Scheduling Problem (open access)

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 (open access)

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."

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."

Collision Loads on Bridge Piers: Phase 2. Report of Guidelines for Designing Bridge Piers and Abutments for Vehicle Collisions

"An instrumented, simulated bridge pier was constructed, and two full-scale collisions with an 80,000-lb van-type tractor-trailer were performed on it. The trailer was ballasted with bags of sand on pallets. The simulated pier was 36 inches in diameter and was supported in the longitudinal direction by two load cells. Force-versus-time data were obtained from the load cells."

Field and laboratory investigations for Full Depth Reclamation projects (open access)

Field and laboratory investigations for Full Depth Reclamation projects

Full-depth reclamation (FDR) offers a timely, cost-effective solution to restore a pavement's condition. However, FDR represents only one technique in the engineer's toolkit available for addressing deteriorating pavement conditions. The purpose of this project is to provide guidance on determining whether a pavement is a candidate for FDR and, if so, what design, construction, and inspection processes will maximize the performance of the completed reclamation. This report presents initial recommendations for selecting a candidate FDR project and developing design options (including field sampling and lab design protocols). Along with a literature review, these recommendations are illustrated by application on several projects in the Texas Department of Transportation's Austin and Dallas Districts.
