FHWA designed the LTBP Program to collect critical performance data that are not available elsewhere and merge them with data gathered from other available sources.
The LTBP Program created InfoBridge to provide a user-friendly web portal that includes intuitive tools for finding, viewing, and analyzing bridge performance information.
It provides for storage, retrieval, dissemination, analysis, and visualization of data collected through State, national, and LTBP Program efforts to provide users with the ability to holistically assess bridge performance on a network or individual bridge basis.
This feature consists of data filter attributes grouped under the categories of National Bridge Inventory (NBI), National Bridge Elements (NBE), and LTBP This feature enables the user to efficiently query the database and present the results both in a paginated tabular view and on a map.
From this level, buyers and sellers can adjust their appraisals on specific site values (LTBP
) according to various micro factors such as size and location.
From this list, they recommended six bridge performance issues as the first topics to be studied under the LTBP
program aims to compile a comprehensive database of quantitative information from a representative sample of bridges nationwide, looking at critical bridge elements and the factors that affect their performance--age, material, design, condition, use, and environment.
"The LTBP program will begin to fill a few of the information gaps that exist in our current program," says FHWA's Everett.
The LTBP program's overall objective is to collect, document, and maintain high-quality quantitative performance data over an extended period of time from a representative sample of bridges nationwide.
FHWA's vision for the LTBP program is threefold, with collection of data being the common thread.
In all three approaches, the LTBP program will take advantage of state-of-the-art sensing and NDE tools.
