Long-Term Bridge Performance
Public release of the InfoBridge web portal occurred in conjunction with the 2019 Transportation Research Board Annual Meeting. Data disseminated and displayed through InfoBridge include both data collected specifically for the LTBP Program and the National Bridge Inventory (NBI). The visualization capabilities provided in InfoBridge are highly beneficial to the States and other highway bridge owners as they work to manage bridge performance.
Status of LTBP Program
The LTBP Program is a long-term research effort, authorized by the U.S. Congress under the Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users (SAFETEA-LU) to collect high-quality bridge data from a representative sample of highway bridges nationwide that will help the bridge community to better understand bridge performance. This site contains information about the program including a discussion of the program objectives and bridge selection methodology (About), LTBP Products, LTBP Community, Nondestructive Evaluation and Structural Health Monitoring as it relates to the Program, and an update on Pooled Fund Project TPF-5(283): The Influence of Vehicular Live Loads on Bridge Performance, and a listing of current LTBP Program Publications.
Long-Term Infrastructure Performance (LTIP) Student Data Analysis Contest
Encouraging Undergraduate and Graduate Students to Explore a Career in Bridge Engineering.
The Federal Highway Administration (FHWA) is pleased to announce the LTIP Student Data Analysis Contest, designed to encourage university students to use bridge performance data to study the various factors affecting bridge lifecycles, and to develop a technical paper to document their research.
Papers must use LTBP InfoBridge™ to investigate a topic that advances bridge performance. Some suggested topics include, “Condition Forecasting Models,” “Trends and Performance History of Different Bridge Types,” and “Role of Preservation in Extending Service Life of Bridges.”
Papers should use the Transportation Research Board’s (TRB’s) formatting requirements as follows:
- File Format: PDF.
- All papers must be submitted in English.
- Include a title page with title, authors, affiliations, and word count.
- Include all coauthor names, affiliations, and email addresses.
- ORCiD numbers are optional, but encouraged.
- Tables and figures should be embedded in the text, near the text that discusses the item.
- 8.5x11 page with normal margins.
- The title should have the first letter of each word capitalized, except for conjunctions, prepositions, and articles.
- Font: Times Roman font, 10 pt size or larger.
- Single spaced.
- Line numbers are required (restart numbering on each page).
- Page numbers are required.
- Manuscript Length: The length of each paper, including the abstract, text, acknowledgments, references, and tables, must not exceed 7,500 words. Each table counts as 250 words. Papers not meeting this requirement may be withdrawn from the peer review process at any time. Abstract (250 words max).
- References should be numbered and called out in numerical order in the text.
View the sample paper taken from TRB. Please note that while the sample paper refers to TRB in the title, this is not a TRB paper. This is a FHWA-sponsored contest. Contestants are to submit papers by email to LTIPStudentContest@dot.gov by Friday, July 30, 2021, 11:59 pm. EDT.
We look forward to your participation in this year’s contest. For more information, contact Shri Bhidé at 202–493–3302 or firstname.lastname@example.org.
