SHRP2 Announces Recipients of Third Round of Funding
The Federal Highway Administration (FHWA) and the American Association of State Highway and Transportation Officials (AASHTO) recently announced the recipients of funding under the third round of the second Strategic Highway Research Program (SHRP2). Organizations in 31 States will receive funds for project implementation and technical assistance.
Program officials also announced the fourth round of SHRP2 products that will move from the research phase to widespread implementation beginning with the Round 4 Implementation Assistance Program. The application process opens March 30, 2014 and closes June 27, 2014.

ASCE Nominates Gucunski as White House Champion of Change
American Society of Civil Engineers (ASCE) nominated Nenad Gucunski, Ph.D., a professor and chair of the Department of Civil and Environmental Engineering at Rutgers University, as a White House Champion of Change. Gucunski, an FHWA contractor, was nominated for his contribution to the FHWA RABIT™ bridge deck assessment tool research project. Individuals selected as Champions are those who have provided exemplary leadership to ensure that transportation facilities, services, and jobs help individuals and their communities connect with 21st century opportunities.
For more information on the RABIT™ bridge deck assessment tool, go to http://www.fhwa.dot.gov/research/tfhrc/programs/infrastructure/structures/ltbp/ltbpresearch/rabit/index.cfm and contact Hamid Ghasemi, 202-493-3042, email@example.com.
Research Leads to Bridge Design Specification Revisions for Modulus of Elasticity of Structural Concrete
AASHTO’s Load and Resistance Factor Design (LRFD) Bridge Design Specification provides the basis for the design of highway bridges in the United States. The concrete structures provisions have been developed over decades, with some of the provisions inevitably becoming less than acceptably accurate as concrete material advancements have opened doors to concretes with advanced mechanical properties.
One fundamental provision relates the compressive strength of concrete to the modulus of elasticity; its influence is significant throughout the structural design specifications. Researchers have recognized that this provision provides insufficient accuracy for modern structural concretes. In an effort to address this issue, researchers involved with FHWA’s Structural Concrete Research Program compiled and analyzed results from hundreds of research studies in order to develop a new relationship for modulus of elasticity. This new relationship has been vetted by the AASHTO Subcommittee on Bridges and Structures Technical Committee #10 (SCOBS T-10), as well as the broader AASHTO community.
In June 2014, this item will go to AASHTO ballot. For more information, contact Ben Graybeal, 202-493-3122, firstname.lastname@example.org.
FHWA Conducts Public Meeting on Data Capture and Management Program
On March 27, 2014, FHWA, in partnership with the DCM Program, held a meeting at the National Highway Institute to seek input on future plans and candidate initiatives for the DCM Program. Participants included public and private sector researchers and stakeholders who will be involved with collecting, developing, implementing, managing, operating, or sharing multisource and multimodal data with traffic management systems or ITS devices to enhance the performance of the surface transportation system.
Workshop topics included the DCM Program’s current and proposed plans and activities; potential private and public sector uses and users of connected vehicle and other sources of multimodal data; potential private and public sector roles and vision for collecting, integrating, managing, and sharing multisource, multimodal data in an operational connected vehicle environment; gaps in practice and knowledge and technologies to assist the public and private sector to collect, use, or integrate connected vehicle data with multisource data; and potential DCM Program initiatives to foster the availability and use of multisource and multimodal data in an operational connected vehicle environment.
For more information about the workshop, contact Jon Obenberger, 202-493-3265, email@example.com. For more information about the DCM Program, visit http://www.its.dot.gov/data_capture/data_capture.htm.
FHWA and AASHTO to Present on the National Connected Vehicle Field Infrastructure Footprint Analysis
The National Connected Vehicle Field Infrastructure Footprint Analysis is a joint effort between FHWA and AASHTO aimed at developing a deployment footprint and plan that will describe the need for connected vehicle infrastructure, the form that the infrastructure should take, where and when the infrastructure should be deployed, and the cost, organizational, and institutional implications of deploying the infrastructure. The analysis will result in a policy foundation for a connected vehicle environment.
The FHWA-AASHTO team presents on the analysis at three upcoming events:
