GENERAL/ADMINSTRATIVE

• FHWA Begins to Implement SHRP2
  
  

  The Federal Highway Administration (FHWA) is working closely with the American Association of State Highway and Transportation Officials (AASHTO) and the Transportation Research Board (TRB) to begin implementing the priority products included in a joint 3-year plan for the Second Strategic Highway Research Program (SHRP2). The plan calls for approximately six SHRP2 products (or product groupings) to begin implementation each year, based on the assessed priority and readiness of each product. The plan also includes specific programmatic activities necessary to support the overall implementation effort.
  
  

  Detailed product implementation plans have been finalized for most of the 2012 products in the plan, and deployment efforts are getting underway. Meanwhile, implementation planning workshops are being scheduled to develop strategies and plans for the 2013 priority products.
  
  

  The new, 2-year transportation authorization, Moving Ahead for Progress in the 21st Century Act (MAP-21), will infuse approximately $75 million in additional implementation funds for SHRP2 through fiscal year 2014. As the lead implementation agent, FHWA is committed to ensuring that States see an early return on their 4 percent State Planning and Research (SP&R) investment in SHRP2.

ADVANCED RESEARCH

• FHWA Signs MOU with NSF to Explore Cyber-Physical Systems
  
  

  FHWA’s Office of Research, Development, and Technology signed a Memorandum of Understanding (MOU) with the National Science Foundation (NSF) Computer Science Directorate to cooperate on cyber-physical systems for highway transportation. A cyber-physical system is an emerging field that tightly couples engineered physical and computational elements into large systems. Cyber physical system applications in highway transportation may include networks, roadside equipment, sensors, or controls that connect to vehicles to improve safety, mobility, or energy efficiency. Applications may also be for bridges and pavements with sensors and actuators to increase resilience or durability. The MOU will allow for closer coordination and leveraging of Federal research funding across agencies, academy, and industry.

• Seeking to Accelerate NDE Innovation
  
  

  FHWA’s Exploratory Advanced Research (EAR) Program and Office of Infrastructure Research and Development (R&D) are seeking organizations interested in contributing to, or participating in a virtual laboratory for nondestructive evaluation (NDE) of highway structures and pavements. A national virtual research laboratory comprised of common physical and virtual experiments could allow researchers from different academic institutions, government agencies, and industries to coordinate and cooperate on NDE research. It could more effectively and quickly allow researchers to build on and advance work conducted by others and increase access to NDE research for new investigators. It also could improve the transition of new methods to practitioners. Elements of a virtual laboratory may include shared access to virtual models of structures, pavements, and sensor and signal processing equipment; corresponding physical laboratory-based models or in situ structures, pavements, and equipment; data from virtual or physical experiments; or other supporting analysis tools.

  For more information, please see the announcement on the EAR Program Web site at https://www.fhwa.dot.gov/advancedresearch/. For more information about the EAR Program, please contact David Kuehn, 202-493-3414, david.kuehn@dot.gov. 

• Experts Discuss Renewable Energy Transportation Research Projects
  
  

  On November 7, 2012 the EAR Program convened a panel at the Turner-Fairbank Highway Research Center (TFHRC) to obtain expert feedback on the EAR renewable energy transportation research projects, “Roadway Wind/Solar Hybrid Power Generation and Distribution System: Towards Energy Plus Roadways” with the University of Nebraska at Lincoln, and “Kinetic-to-Electric Energy Conversion (KEEC) Technology as a Roadway Energy Harvester” with Virginia Polytechnic Institute and State University (Virginia Tech).
  
  

  The feedback will be considered in developing a strategy to maximize success for implementation of the resulting technologies. Staff from State departments of transportation, Federal agencies, nonprofits, and universities participated in the meeting.

• Video Analytics Workshop Held at TFHRC
  
  

  On October 10–11, 2012, FHWA’s EAR Program and the Office of Safety R&D sponsored a workshop on “Applying Automated Feature Extraction to Questions of Driver Behavior” at TFHRC. The purpose was to identify efficient and cost-effective methods and tools to analyze the large amounts of video-related safety data generated by studies such as the SHRP2 Naturalistic Driving Study. Such tools are expected to help the safety community dramatically increase its understanding of relationships between driver behavior and safety, which will advance guide development of safety improvements in infrastructure and other areas. The EAR Program anticipates publishing a workshop summary by January 2013. 

  For more information about the workshop, contact Lincoln Cobb, 202-493-3313, lincoln.cobb@dot.gov. For more information about the EAR Program, contact David Kuehn, 202-493-3414, david.kuehn@dot.gov.

• EAR Program Explores Casual Carpooling in Three Cities
  
  

  In 2010 (between November and December), the EAR Program supported a team of transportation professionals, academics, and entrepreneurs who visited informal carpool lines (also known as slug lines or casual carpool lines) in Washington, DC; Houston, TX; and San Francisco, CA. The team observed “slugs” and compared practices among locations. They also met with private ride-match providers, regional planners, carpool participants, and transportation planners and engineers. Scan team participants produced a report that outlined what they learned at the dynamic ridesharing sites and identified gaps in the data and research.
  
  

  The scan report is available at https://www.fhwa.dot.gov/advancedresearch/pubs/12053/index.cfm. Appendix B in the report, available at https://www.fhwa.dot.gov/advancedresearch/pubs/13023/index.cfm, contains the personal observations from scan team members. Foundational knowledge gained from the scan will serve as a springboard for future projects, collaborations, and system expansion.

INFRASTRUCTURE

• TechBrief: Application of Radiographic Testing to Multilayered Gusset Plate Inspection
  
  

  Corrosion of gusset plates was noted as an issue of concern by the National Transportation Safety Board at the conclusion of the I-35W bridge collapse investigation. In response, FHWA developed a Technical Advisory to alert owners of this concern and offer suggestions about how these plates could be assessed. When the Technical Advisory was written, there were no technologies that could be suggested for assessing multilayered plates. This TechBrief discusses the efficacy of radiographic inspection for these types of gusset plates.
