The objective of this research project was to produce a synthesis of available information to support specific areas related to pavements for the safe, economical development of the Trans Texas Corridor (TTC). This synthesis is divided into nine sections, each of which deals with a specific topic or topics. These specific areas include (1) pavement design for heavy vehicles, (2) pavement design for light vehicles, (3) skid resistance issues on high-speed corridors, (4) issues related to traffic characterization, (5) smart pavements for high-speed corridors, (6) pavement material response to dynamic loads and performance prediction, (7) safety issues related to splash and spray, and (8) ride quality for high-speed corridors. Regarding these stated issues, this synthesis recommends state-of-the-art technology to the Texas Department of Transportation (TxDOT) for use during development of the TTC. It provides recommendations for future research to fill gaps in knowledge and to take emerging technology to the stage where it can be implemented during the design and construction of the TTC pavements. This is the first synthesis study to address issues related to the TTC. A secondary objective of this project was to determine if additional synthesis studies in other areas of transportation related to the TTC should be conducted and, if so, how the process might be improved. This synthesis recommends that future syntheses should be more focused on specific, maybe critical, issue(s); the researcher should be instructed to present only those findings that are really new, innovative, and potentially implementable. One element of the study should pursue non-transportation related technology that might be adapted to transportation issues.

The overall objectives of this research study may be stated as follows: Determine if surface characteristic measurements can be correlated to wet-pavement crashes in Ohio; Provide improved guidance on the use of ribbed versus smooth tires for pavement surface friction testing in Ohio, including the identification of suggested minimum surface friction numbers associated with each tire type; Provide recommended desirable or target surface friction numbers as a function of site categories and friction demand. Accomplishments of these objectives will help ODOT address their goal of reducing total crashes 10 percent and rear-end crashes by 25 percent by 2015.

NCHRP Report 649/NCFRP Report 3: Separation of Vehicles - CMV-Only Lanes presents an extensive compendium of information about CMV-only lanes and examines major issues and concepts that should be understood in developing new applications of CMV-only lane concepts as a potential method for both easing congestion and reducing the number of traffic accidents on highways. Appendices to this report, including an annotated literature review, performance evaluation criteria, benefits monetization factors and unit costs, and net present value calculations for benefit-cost analysis, are available on the TRB website. This report and the supplemental information can be used by public agencies that may be considering CMV-only lane concepts in corridor studies or other planning applications. The report provides data such agencies can use to support their own evaluations of CMV-only lane projects.

The proliferation of technological capability, miniaturization, and demand for aerial intelligence is pushing unmanned aerial systems (UAS) into the realm of a multi-billion dollar industry. This book surveys the UAS landscape from history to future applications. It discusses commercial applications, integration into the national airspace system (NAS), System function, operational procedures, safety concerns, and a host of other relevant topics. The book is dynamic and well-illustrated with separate sections for terminology and web- based resources for further information.
