"This report describes the work completed to measure the impact of increased level of energy-related activities on the Texas Department of Transportation (TxDOT) right-of-way and infrastructure, as well as develop recommendations to reduce and manage TxDOT's exposure and risk resulting from those activities."

This report describes a study showing that the Soil Compactor Analyzer(SCA) enables excellent precision precision of total statistics of test method Tex-113-E.

Report regarding efforts to develop a benefit-cost analysis methodology for safety rest areas in Texas and to demonstrate its application in select corridors throughout the state. This project also considers approaches to developing rest areas that could reduce costs to the public.

"In this report the research project resulted in a statewide map recommending primary and alternate Oversize/ overweight (OS/OW)route networks for the most common origins and destinations based on historical Motor Carrier Division data. Keeping strategic routes open for OS/OW loads and minimizing the number of reroutes along the way will reduce the impedance and unknowns in this critical segment of the motor carrier industry."

Report regarding efforts to identify a technique to map the sulfate content of soil over a large area to a depth of 3 to 4 feet. Two devices are noted: an electromagnetic device called EM-38 and a soil conductivity device called VERIS 315.

"This report aimed to conduct a comprehensive evaluation of compaction of asphalt pavements and develop software for monitoring field compaction in real time.The results were used to determine the effects of compaction temperature, compaction method, mixture design, and base type on the compactability of asphalt mixtures.Also in this report researchers developed a system for monitoring and documenting the compaction process of asphalt mixtures called compaction monitoring system (CMS)."

Report on research performed on the application of instruments including accelerometers and tiltmeters to monitor bridge scour. The instrumentation on the two bridges does not show great hope of application of accelerometers to monitor bridge scour because of a lack of sufficient excitation from traffic. Tiltmeters can provide the integral behavior of the bridge, and therefore are very useful devices for scour monitoring. Guidelines and protocols for scour monitoring based on the US59 over Guadalupe River Bridge and the SH80 over San Antonio River Bridge are provided in the study.

Report that looks at the state of mobility management practice throughout Texas, as well as national best practices in mobility management. Additionally, this research provides an overview of the varying roles of state departments of transportation in public transit mobility management efforts. The research also presents applied mobility management for agencies seeking to implement mobility management programs as well as a menu of performance measures that can be utilized based on the type and level of program implemented.

Report regarding research into cheaper alternatives for the construction of pavement subbases that maintains adequate pavement performance.

"This report evaluated Texas Department of Transportation's (TxDOT) current sign retroreflectivity maintenance practices, assessed their effectiveness, and recommended statewide sign retroreflectivity maintenance practices that could be easily and effectively implemented to ensure that TxDOT would be in compliance with the new Manual on Uniform Traffic Control Devices (MUTCD) language related to minimum sign retroreflectivity."

This report describes the current state of practice of microsurfacing in Texas and compares it to best practices extracted from existing literature. A survey of DOT personnel, contractors and emulsion suppliers in Texas provides insight into the most crucial factors contributing to the success or failure of a microsurfacing. From the results of the survey, literature reviews, case studies and site visits, the research team analyzed material selection and mix design methods, construction practices, equipment practices and performance measures for microsurfacings.

"This report focused on the evaluation of traffic sign sheeting performance in terms of meeting the nighttime driver needs. Using the luminance requirements derived from the study and market-weighted headlamp flux matrices, the researchers developed an approach to sigh sheeting specification that is based on nighttime driver needs."

"This project focused primarily on the specific issue of developing a new technical tool to help TxDOT and other key operating agencies/stakeholders better predict when major elements of evacuation operations should be implemented."

Report identifying the issues, and infrastructure needs concerning access to airports in Texas for both travel and freight shipping purposes and proposing solutions to the identified problems.

This report looked at the current Texas Department of Transportation Travel Demand Model (TxDOT TDM) and found that they do not include any impedance or accessibility measures in the trip generation step and found that the best approach is to feed back the output from the traffic assignment step to the trip distribution step.

"This project researched current trends, practices, and tools in implementing a feedback approach for potential implementation in the TxDOT TDMs."

"This two-year project was designed to provide TxDOT with comprehensive review and update of mounting details and standards for large and small sign supports, and to provide a mechanism for TxDOT to quickly and effectively evaluate and address high priority needs related to sign support systems."
