FHWA at TRB's Annual Meeting -
FHWA valued the opportunity to meet with stakeholders at the Transportation Research Board (TRB) 89th Annual Meeting: Investing in Our Transportation Future-BOLD Ideas to Meet BIG Challenges. Out of the nearly 500 FHWA employees who participated in the 2010 TRB annual meeting, 120 of them participated in technical sessions. FHWA hosted 45 additional meetings and displayed more than 35 exhibits.
Certificate of Appreciation Awarded at TRB International Participants' Reception
Dr. John Munro and Ms. Debra Elston were honored by TRB for their contributions to the report entitled European-United States Transportation Research Collaboration, Challenges and Opportunities. A special certificate of appreciation was awarded to them at Sunday's TRB International Participants' Reception, in the Hilton Hotel's International Ballroom East.
Every Day Counts Initiative
Since the launch of FHWA Administrator Victor M. Mendez's Every Day Counts (EDC) initiative, the accelerated deployment of innovative technologies team has identified 13 candidate technologies/groups of technologies using a collaborative process based on input from FHWA staff and stakeholders. This was particularly challenging because there are so many promising technologies. On January 26 a selection panel comprised of FHWA staff and stakeholders will review and rate the candidate technologies to narrow the selection to approximately five technologies. Following the selection, FHWA will establish Innovation Deployment Partnership Teams (IDPTs) to develop and carry out the implementation plans comprising roadmaps, and communication and marketing plans. The IDPTs will be responsible for identifying implementation strategies, providing technical support, developing performance measures, defining expectations, monitoring results, documenting best practices, and reporting outcomes. Each deployment plan will include specific milestones, budget and resource projections, and completion targets. FHWA expects to complete the implementation plans by April 2010, bearing in mind that "every day counts."
The Accelerating Innovative Technologies component of the EDC Initiative will provide an opportunity to focus on several promising technologies so they become state-of-the-practice solutions in order to address some of the most challenging issues facing the Nation. FHWA plans to improve the overall delivery for the future efforts, building on current initiatives and lessons learned from programs such as Highways for LIFE.
FHWA welcomes suggestions on how the Agency can accelerate the delivery of innovative technologies and enhance the methods for accelerated deployment. A dedicated electronic mailbox has been established for staff and stakeholder contributions: firstname.lastname@example.org
Planning for SHRP 2 Implementation
Strategic Highway Research Program (SHRP) 2 research continues to progress on schedule, and has reached the midpoint of its 7-year life. The first research results are now becoming available, and FHWA is actively working with TRB and the American Association of State Highway and Transportation Officials to guide the pre-implementation planning phase of SHRP 2. SHRP 2 Implementation Team Director Margie Sheriff is busy engaging all FHWA staff in discussions on SHRP 2 research and the roles the program offices, division offices, and the Office of Technical Services will play to ensure a smooth transition from research to deployment. FHWA is also working with the National Highway Traffic Safety Administration to plan for the SHRP2 Safety research results. SHRP2 implementation is a priority within FHWA's FY2010 Strategic Implementation Plan. The scale of the implementation effort will depend on program funding for SHRP 2 implementation, which will be decided once Congress passes authorization legislation and appropriates funds.
RITA Seeking Input on Its 5-Year Strategic Plan
The Research and Innovative Technology Administration (RITA) and its partners are seeking public stakeholder input on research strategies and metrics necessary to achieve USDOT strategic transportation goals and to drive transportation policy in both the short and long terms. The USDOT's research, development, and technology efforts and outcomes play critical roles in attaining the vision of a safe, truly multimodal transportation system that provides the traveling public and U.S. businesses with safe, convenient, affordable and environmentally sustainable transportation choices. A previous USDOT Research, Development, and Technology Strategic Plan was published in 2006 and served as a compendium of modal research pursuits at that time. USDOT is now pursuing a more cross-modal, collaborative and strategic planning process to cover the years 2010-2015 and to address the proposed departmental key priorities as outlined in the Federal Register background section. The Federal Register notice is open for comments until February 8, 2010.
FHWA EAR Program Results
The Exploratory Advanced Research (EAR) Program strives to develop partnerships with the public and private sectors because the very nature of EAR is to apply ideas across traditional fields of research and stimulate new approaches to problem solving. Between FY 2007 and FY 2009, the EAR Program awarded 25 projects involving both government and academic researchers. These projects represent the investment of $22.6 million in FHWA funds and leverage $12 million in matching funds. The EAR Program bridges basic research (e.g., academic work funded by National Science Foundation grants) and applied research (e.g., studies funded by State departments of transportation). Research may include improved understanding of phenomena that can accelerate or allow for new lines of applied research. An example is a project called "Increased Understanding of Driver Visibility Requirements," in which investigators are developing a rational, theoretical framework for determining the quantity and quality of visual information needed by drivers to navigate the roadway safely and effectively. This work will assist in future safety research. In addition to sponsoring EAR projects that advance the development of highway infrastructure and operations, the EAR Program is committed to promoting cross-fertilization with other technical fields, furthering promising lines of research, and deepening vital research capacity.
FHWA EAR Program Awards Research on Nanoscale Approaches for Inhibiting Corrosion
As a result of a Broad Agency Announcement for EAR Proposals issued in April 2009, FHWA entered into a cooperative agreement with the City College of New York to develop novel, nanotechnology-based green coatings for corrosion protection of new and existing steel highway infrastructure. For this research project, the researchers will investigate two coating systems and compare them to traditional steel anti-corrosive coatings. They will use conductive polymer nanoparticles in the two proposed coatings to provide electrochemical corrosion inhibition, carbon-black additives to improve the scratch resistance and toughness of these coatings, and metallic nanoparticles to improve the dispersion of the additives. They will then compare the proposed new coatings to a traditional zinc-enhanced, epoxy-based coating for both mechanical strength and corrosion protection. The advantage of the nanotechnology-based coatings lies in their expected ability, with a very low concentration of additives, to provide significant corrosion protection while improving adhesion strength and scratch resistance. This could lead to significant savings in their life-cycle costs. For more information about the project, contact Paul Virmani, (202) 493-3052, email@example.com.
FHWA EAR Program Initiates Research on Innovative Approaches for Next Generation Vehicle Positioning
FHWA entered into a contract with the University of California, Riverside, for a 3-year research project on vehicle-infrastructure cooperation technologies. Researchers will assess the viability, benefits, limitations, and obstacles for different approaches for vehicle positioning based on technological, business, and deployment characteristics. In particular, they will focus phase I of the research on how the sensors measuring the physical road environment (vision, radar and lidar), electromagnetic infrastructure (Next Generation Vehicle Positioning), and local vehicle-to-vehicle and vehicle-to-infrastructure communications infrastructure can serve as additional augmentation mechanisms to improve vehicle positioning. A second phase will include the testing of several of the viable approaches. The award is a result of a national Broad Agency Announcement for EAR Proposals issued in December 2008. For more information about the project, contact David Gibson, (202) 493-3271, firstname.lastname@example.org.
Fact Sheet: Time-Frequency Analysis Mathematical Analysis of the Empirical Mode Decomposition
Over the past decade, Empirical Mode Decomposition (EMD) has been used in a wide range of fields, including biology, geophysics, ocean research, radar, and medicine. The algorithm has been fine-tuned and extended in a variety of different directions, however, remarkably little is known about the mathematical properties, and very little mathematical research had been conducted on EMD. EMD's ability to detect subtle changes in time-dependent signals makes it of particular importance and highly relevant to transportation requirements. In addition to assessing and monitoring bridges and structures, it serves as a vital tool in the detection of early signs of fatigue in vibrating metal components and can detect even the onset of irregularities in engine function that precede major breakdowns. Early detection of subtle changes makes it possible to diagnose serious mechanical problems in machinery before they are permitted to cause serious damage. The innovative ideas developed for this project can currently be categorized into two classes: one part researching a "mathematical cleanup" of the sometimes very ad hoc components of the EMD algorithm, and the other part, a "mathematical reformulation," attempting to develop a more rigorous mathematical approach in the same spirit as the original EMD, but using different geometric tools.

Fact Sheet: Real-Time Pedestrian Detection Layered Object Recognition System for Pedestrian Collision Sensing
At this time pedestrian detection can be achieved using fixed cameras pointing at predetermined zones, or through the use of vehicle-mounted camera systems. Both systems can detect pedestrians, while vehicle-mounted systems can also detect additional objects such as other vehicles, buildings, and zebra crossings. This EAR project moves beyond current systems and integrates two- and three-dimensional technology to provide cues for potential locations of pedestrians.

Fact Sheet: Driving Automation Forward: Human Factors for Limited-Ability Autonomous Driving Systems
In-vehicle innovations have steadily evolved to supplement the driver's ability during normal driving and to augment the driver's ability to respond to critical situations. Most recently, some manufacturers in Asia and Europe already have introduced collision-mitigation braking systems and lane-keeping systems. New features, such as a lane-centering system that also controls steering, indicate that it will not be long before vehicles are on the market that can move autonomously for substantial distances toward a destination with limited driver input.
This EAR project addresses a critical technology and knowledge gap that limits the near-term availability of vehicles able to control their own speed and steering for substantial distances on public roads. This gap exists in how to help drivers maintain adequate situation awareness so that they are prepared to intervene when traffic conditions require. With this in mind, two next-generation driver-assistance technologies that provide longitudinal and lateral control automation, smart adaptive cruise control and lane centering, will be used in human factor studies and experiments in simulators, on test tracks, and on public roads. These trials will address concerns raised by previous research, regarding the need to carefully design autonomous driving systems to avoid potential adverse effects from driver inattention, when they are made available to the general public.

Report: Development of a Multiaxial Viscoelastoplastic Continuum Damage Model for Asphalt Mixtures
This report highlights findings from the FHWA project that focused on the development of the multiaxial viscoelastoplastic continuum damage model for asphalt concrete in both compression and tension.
Introducing the Crash Modification Factors Clearinghouse
The FHWA has established the Crash Modification Factors (CMF) Clearinghouse to support and enable transportation professionals to identify the most appropriate countermeasure to address their safety needs. A CMF is a multiplicative factor used to compute the expected number of crashes after implementing a given countermeasure at a specific site. The CMF Clearinghouse presents both CMFs and Crash Reduction Factors (CRF), which are estimates of the percentage reduction in crashes. The CMF Clearinghouse contains a searchable database of CRFs, allowing users to search by countermeasure, crash type and severity, as well as other variables. Transportation professionals can also submit their own CMF studies for inclusion into the CMF clearinghouse.

Older Driver/Senior Mobility Series
Because the number of older drivers is increasing—by the year 2020, adults aged 65 and older are projected to make up 20 percent of the population—it is necessary to design highways and roadside equipment with older drivers in mind. For a better understanding of older drivers and transportation, see articles that were printed in the FHWA's Public Roads magazine at:
TechBriefs Present Six Alternative Intersections and Interchanges
The Office of Safety R&D announces the availability of six technical summaries (TechBriefs) of recently completed research into alternative intersections and interchanges. These nontraditional designs offer substantial advantages under certain conditions compared to corresponding conventional at-grade intersections or grade-separated diamond interchanges. The TechBriefs, and the corresponding full report (see below), address geometric design features, operational and safety issues, access management, costs, construction sequencing, environmental benefits, and applicability of each design.
The complete final report of this work will be available in the Spring, 2010, and will cover all six designs in greater detail. That report is titled Alternative Intersections/Interchanges: Informational Report (FHWA-HRT-09-060).

Report Considers the Effects of In-Vehicle and Infrastructure-Based Collision Warnings at Signalized Intersections
The Office of Safety R&D has released a report titled "The Effects of In-Vehicle and Infrastructure-Based Collision Warnings at Signalized Intersections" (FHWA-HRT-09049). The potential effectiveness of warnings to drivers of the imminent threat of a collision with a red light violator was evaluated in an experiment that used a driving simulator. Three warnings were tested: (1) an infrastructure-based warning that immediately turned the traffic signal red and activated red wig-wag lights, (2) an in-vehicle warning that consisted of a brake pulse, voice annunciation, and activation of a red dashboard light, and (3) simultaneous activation of both of these warnings. In addition to testing three warnings with different groups of drivers, drivers in each group were exposed to one of three traffic conditions: (1) driving with no other vehicles ahead or behind, (2) following closely to another vehicle, or (3) being closely followed by another vehicle.
