FHWA Hosts Nano-Scale Research Workshop
On March 5-6, FHWA hosted a workshop to identify interests and capabilities for nanoscale research that can be applied to highway industry subject matters. The workshop connected technical
experts from University Transportation Centers, federal laboratories, and other sources who are conducting relevant nanoscale research. The information and thoughts shared at this meeting will shape the scope of FHWA investment in nanoscale research through an open solicitation, interagency
agreement, or other appropriate mechanisms. For more information, contact:
FHWA Exploratory Advanced Research Program Partners with SCOR on Strategic Research
The FHWA Exploratory Advanced Research (EAR) Program will solicit and fund research for one of the topics identified for NCHRP 20-83, Long-Range Strategic Issues Facing the Transportation Industry. The American Association of State Highway
and Transportation Officials' Standing Committee on Research (SCOR) approved solicitation of five topics and funding two additional topics in FY 2010 as part of a new Long-Range Strategic Issues project. To accelerate the research, FHWA offered to fund one additional project, "Multi-Modal Connectivity Options for a Future Seamless Transportation System." Researchers for the project will study the range of possible multi- and inter-modal connectivity options, looking 30 to 50 years ahead and focusing on optimizing different forms of system capacity, improving reliability, and creating a seamless, safe transportation system. The EAR Program is soliciting proposals on the topic from all sources and is seeking candidates to serve on an expert
panel to provide technical oversight of the project similar to panels formed for the National Cooperative Highway Research Program (NCHRP). For more information, contact:
ENR Top 25 Newsmaker for 2008
Mike Adams, Research Geotechnical Engineer at TFHRC was selected by Engineering News Record (ENR) to highlight as one of their Top 25 Newsmakers for 2008. Mike is known for his dedicated promotion of geosynthetic reinforced soil (GRS) technology used for building efficient and cost effective bridge substructure components, which has been an integral part of FHWA's Bridge of the Future initiative.

Long-Term Bridge Performance Program
The Long-Term Bridge Performance (LTBP) program team has conducted "Focus Group" meetings with 8 state DOT offices to discuss performance and maintenance issues that the states encounter on a regular basis; 5 additional state meetings have been scheduled. Not surprisingly, some of the key issues the states have identified include: bridge deck performance and corrosion concerns, bridge deck joint performance, bearing performance, and scour and scour countermeasures issues. From this, a preliminary set of program data requirements and bridge performance metrics has been developed. The next phase of work is initiation of a pilot program to assess data collection protocols and guidelines for the LTBP visual inspections, bridge instrumentation, and NDE. Two bridges have been selected for the pilot program to test and validate these protocols and guidelines for implementation (one each in VA and UT). Other states to be included are likely to run through 2011. For information on the LTBP program see the LTBP program Web site at:
Long-Term Pavement Performance Computed Parameter: Frost Penetration
This report will be of interest to highway agency engineers as well as researchers who will use the LTPP frost penetration data to improve pavement design and analysis procedures.
Long-Term Pavement Performance (LTPP) Manual for Profile Measurements and Processing
This manual describes operational procedures to be followed when measuring longitudinal pavement profiles for the LTPP program.
Ver. 2 of Surrogate Safety Assessment Model (SSAM) Available – Free Download
SSAM conducts conflict analysis and performs statistical analysis of vehicle trajectory data output from common microscopic traffic simulation models. The software computes a number of surrogate measures of safety for each conflict that is identified in the trajectory data and then computes summaries (mean, max, etc.) of each surrogate measure. This approach yields crash frequency predictions for hypothetical designs and control alternatives, and is applicable to facilities where traditional, volume-base crash-prediction models have not been established.

FHWA Senior Mobility Initiatives/Updates
The FHWA senior mobility program centers on providing highway engineers and transportation specialists with older road user guidelines. Since 1998 we have provided the transportation community with these guidelines in the "Highway Design Handbook for Older Drivers and Pedestrians". This Handbook defines the physical changes of and cognitive changes in older drivers and pedestrians and recommends roadway designs and strategies which will accommodate these
aging drivers and pedestrians. This Handbook, now in its third reiteration, will include reference
to the most current traffic control standards, and best practices practiced around the country. Release of this updated Handbook will be in 2010 following publication of the new MUTCD. Also, the
FHWA provides States with training on how to understand and apply these guidelines through classes provided by the Resource Center. These workshops can be requested by the States and are provided free of charge. For more information on the "Highway Design Handbook for Older Drivers and Pedestrians", contact:
