Long-Term Bridge Performance Program Research Index
Pennoni’s Intelligent Infrastructure Systems (IIS) is working with Federal Highway Administration to develop an index that is primarily intended to be used for research purposes in the context of the LTBP Program. The index includes some subjective components (due to the current lack of quantitative performance data), but it is expected to become increasingly data-driven and objective as the LTBP Program expands its field data collection efforts. It is also expected that the LTBP Research Index will help to clarify the complex roles that various aspects of bridge performance have on overall performance of the bridge within the context of the LTBP Program. The proposed framework for the Index will require extensive testing and validation and multiple phases of refinement over the course of the LTBP program.
