Planning for the Second SHRP2 Implementation
There are more than 80 Strategic Highway Research Program (SHRP 2) research projects, and all except one are underway. The Transportation Research Board (TRB) is convening implementation planning workshops to facilitate the deployment of early SHRP 2 products. TRB's SHRP 2 staff members, working in conjunction with the Technical Coordinating Committees, have reviewed projects nearing completion and identified those that warrant pre–implementation initiatives or further research during 2011. FHWA liaisons and technical staff members are fully engaged in this process.
The current continuing resolution extended the Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users surface transportation authorization through March 4, 2011 and amended Section 510 of Title 23 to allow the Secretary of Transportation to use SHRP 2 funds for implementation of research products related to SHRP 2. This includes development, demonstration, evaluation, and technology transfer activities. FHWA is taking a measured approach and carefully assessing those SHRP 2 products that the agency is best positioned to deploy. FHWA continues to collaborate with TRB, the American Association of State Highway and Transportation Officials (AASHTO), and the National Highway Traffic Safety Administration to educate and position our agencies, State departments of transportation and industry for deployment of SHRP 2 research results. This multi–organizational approach to implementation activities will ensure that proper preparations are made for the establishment of a formal SHRP 2 Implementation Program, upon reauthorization.

FHWA EAR Program Builds on Emerging Information Technologies for Multimodal Integration
FHWA entered into a contract with the University of Southern California to develop a new type of decentralized transportation system capable of real–time allocation of resources. The premise is that an intelligent use of traffic information and dynamic trip matching will enhance private transportation decisions, tapping into unused vehicle capacity, radically transforming the way people use transportation systems. For more information on this Exploratory Advanced Research (EAR) Program project, contact Karen White, 202–366–9474, email@example.com.

FHWA EAR Workshop Explores Technological Innovations in Transportation for People with Disabilities
On February 23, FHWA's Office of Operations Research and Development (R&D) is conducting a workshop at the Turner–Fairbank Highway Research Center for technology and disability experts outside transportation to discuss how technological advancements could help to empower people with disabilities to become more mobile. The workshop participants will discuss technologies, such as mobile computing, computer vision, artificial intelligence, and robotics, that could be used for innovative ways to help those with vision impairment and cognitive impairments be more independent. The workshop will also connect FHWA technical experts with those from the University Transportation Centers, Federal agencies, and other sources who are conducting relevant accessible transportation research. For technical information about this EAR Program investigation, contact Mohammed Yousuf, 202–493–3199, email@example.com.

Geosynthetic Reinforced Soil Integrated Bridge System, Interim Implementation Guide
Geosynthetic Reinforced Soil (GRS) technology consists of closely spaced layers of geosynthetic reinforcement and compacted granular fill material. GRS has been used for a variety of earthwork applications since the U.S. Forest Service first used it to build walls for roads in steep mountain terrain in the 1970s. Since then, the technology has evolved into the GRS Integrated Bridge System (IBS), a fast, cost–effective method of bridge support that blends the roadway into the superstructure. GRS–IBS includes a reinforced soil foundation, a GRS abutment, and a GRS integrated approach. The application of IBS has several advantages. The system is easy to design and economically construct. It can be built in variable weather conditions with readily available labor, materials, and equipment and can easily be modified in the field. This method has significant value when employed for small, single–span structures meeting the criteria described in this manual.
As a result of the demonstrated performance of GRS–IBS, the technology was selected for the Federal Highway Administration's (FHWA) Every Day Counts initiative, aimed at accelerating implementation of proven, market–ready technologies. This manual is the first in a two–part series and outlines the design and construction of GRS–IBS.

Geosynthetic Reinforced Soil Integrated Bridge System Synthesis Report
This report is the second in a two–part series and provides the background and other supporting information to substantiate the design method of GRS–IBS. The first document is a manual covering the design and construction of GRS–IBS. This two–part document series designs GRS as a composite material with known and predictable performance and deformations. Both documents are a collaboration between many disciplines within FHWA: geotechnical, structural, hydraulic, maintenance, and pavement engineering.

FHWA Publishes the Model Inventory of Roadway Elements
The FHWA Office of Safety and Office of Safety R&D announce the release of the Model Inventory of Roadway Elements Version 1.0 (MIRE 1.0). Safety data have long been the key to sound decisions about the design and operation of roadways. The emergence of safety analysis tools, such as SafetyAnalyst, the Interactive Highway Safety Design Model (IHSDM), and other procedures identified in the new Highway Safety Manual, has sharply increased the need for more and better safety data, such as crash data, roadway inventory data, traffic data, driver history data, citation/adjudication information, and other files.
MIRE 1.0 provides standardized definitions of roadway and traffic data elements, including coding for consistent capture of those data elements in databases.
The MIRE Report can be found online at: http://safety.fhwa.dot.gov/tools/data_tools/mirereport/. Additional background information, resources, and discussion forums can be found at the MIRE Web site at www.mireinfo.org.
FHWA Releases Software Suite Update
The FHWA Office of Safety R&D announces that the updated version of 2010 Public Release of Interactive Highway Safety Design Model (IHSDM)—Highway Safety Manual (HSM) Predictive Method (version 6.0.2) is now available for free downloading at www.ihsdm.org.
