InfoBridge Update Notes

March, 2021

The following data updates, enhancements, and bug fixes have been implemented:

  • NBI Annual Data Augmentation - The NBI/NBE data is now available for the 2020 submittal.

  • Climate Data Update - The 2020 climatic data has been added. InfoBridge™ climate data is obtained from NASA’s Modern-Era Retrospective analysis for Research and Applications Version 2 (MERRA-2) data, which is currently available from January 1, 1980 to December 31, 2020.

  • Historical Spec Changes - The Historical Spec Changes feature under the Library menu has been updated to include a new module: Steel Bridges. This module provides a historical review of how steel composition, steel properties, and steel bridge design evolved from 1900 to 2015. The information presented here is adopted from the Federal Highway Administration report FHWA-HRT-21-020. This report was developed by staff from the Office of Infrastructure Research and Development.

  • Miscellaneous Bug Fixes - Several web interface and map bugs have been fixed in this release.

January, 2021

The following data updates, enhancements, and bug fixes have been implemented:

  • Full Width Graphical User Interface (GUI) - The InfoBridge™ web portal has been updated to full width design. Users can navigate through the portal using wider screens for a better visualization. Various tabs have been restructured and features have been realigned, for example, Historical NBI Condition and Traffic trend graphs have been moved within the NBI Data Tab.

  • Data Selection/Presentation Option for Historical Data - An additional data filter has been provided as “Select Data” feature to toggle selection of bridges between displaying only the latest NBI data or to include all historical data submitted since 1993. The options under Select Data can be used to determine which records are filtered using Find Bridges, Advanced Find, and/or Map Find. Users can now view the historical data submitted since 1993 in the Selected Bridges Table and the NBI Data Tab using this option.

  • Performance Forecast - A new tab titled “Performance Forecast” is implemented to show preliminary results of ongoing FHWA research on condition forecast for a group of bridges selected by the user. This includes graphs displaying the historical and forecasted condition of bridges by count and percentage of the selected group of bridges in Good/Fair/Poor rating along with the percentage of deck area in each condition state (Good/Fair/Poor). Users can select from the available Network Performance Forecast models and preservation levels using the available model selection tree. Please note that the “Performance Dashboard” feature is still maintained and has been renamed “Performance History”.

  • Charts for National Bridge Elements (NBE) - Data attributes have been included for National Bridge Elements (NBE) data for the Single Variable Chart feature under the Analytics/Charts menu. The available attributes include Element Type and the Percentage of Element in each of the four Condition States (CS-1, CS-2, CS-3, and CS-4).

  • Geosynthetic Reinforced Soil – Integrated Bridge System (GRS-IBS) Project Data - A new data tab for Geosynthetic Reinforced Soil – Integrated Bridge System (GRS-IBS) Project has been added. The data available under GRS-IBS Data tab include data for Structure Type and Elements, Dimensions and Clearances, Load Rating and Posting, Stream Information and Primary Drivers for the GRS-IBS project bridges.

  • Filter Options for Special Projects - Additional filter options have been provided for Special Projects under the Find Bridges and Advanced Find features. Users can select the group of bridges included in the Special Project using the Find Bridges filters, and can further narrow down their search based on Special Project data attributes using the Advanced Find filters.

  • Updates for Map Find Tool - Map Find feature has been updated to provide a search operator for finding location using Latitude and Longitude. Additionally, the line tool has been updated to allow for drawing multiple line segments for selecting the bridges along meandering lines, such as highway corridors, state boundaries, coastlines, etc.

  • Interactive Crack Map for Non-Destructive Evaluation (NDE) - The Non-Destructive Evaluation (NDE) crack map has been updated to allow for interactive control to view bridge deck images using the bridge deck coordinates.

  • Miscellaneous Bug Fixes - Several web interface and map bugs have been fixed in this release.

July, 2020

The following data updates, minor enhancements, and bug fixes have been implemented:

  • Unpainted Weathering Steel (UWS) Project Data - A new data tab for Unpainted Weathering Steel (UWS) Project has been added. The data available under UWS Data tab includes geographic, climatic, and environmental data for the bridges analyzed for the UWS Project.

  • Charts Feature (Analytics) - The Charts feature under Analytics menu has been updated to display two new NBI attributes: Inventory Route, Minimum Vertical Clearance (NBI Item #10), and Year of Average Daily Traffic (NBI Item #30). Additionally, the bin sizes for various attributes have been updated to display non-uniform bin sizes.

  • Structure Number Format - The format for displaying and exporting Structure Number has been updated to reflect all leading and trailing spaces and leading and trailing zeros according to the NBI Data Submittals. This update is available for the Selected Bridges table and Export Data under Options menu.

  • Code Expansion for all Hybrid Coded NBI Fields - All hybrid coded NBI fields (fields that may either contain numeric or coded values) have been updated to display codes as “XXXX”. This update is available for NBI Data Tab under Data menu and Charts feature under Analytics menu.

  • Condition Forecast Data for Bridge Deck Models - The data for the Condition Forecast graph has been updated to reflect the most recent NBI submittal.

  • Legend for Non-Destructive Evaluation (NDE) graphs - The graphs for Non-Destructive Evaluation (NDE) under Graphs tab under Data menu have been updated to separate the legend color options from the slider for value range selection.

  • LTBP Documentation (Library) - A new tab under Library menu has been added for LTBP™ Documentation. This tab includes LTBP Protocols and LTBP Newsletters.

  • “Contact Us” Details (Help) - A new tab for Contact Us has been added under Help menu with contact information for LTBP™ Customer Support Service Center.

  • Miscellaneous Bug Fixes - Several web interface and map bugs have been fixed in this release.

March, 2020

The following data updates, minor enhancements, and bug fixes have been implemented:

  • NBI Annual Data Augmentation - The NBI/NBE data is now available for the 2019 submittal.

  • Climate Data Update - The 2019 climatic data was added. InfoBridge™ climate data is obtained from NASA’s Modern-Era Retrospective analysis for Research and Applications Version 2 (MERRA-2) data, which is currently available from January 1, 1980 to December 31, 2019.

  • Climate Data Download - Two climate data attributes (Number of Freeze/Thaw Cycles and Number of Snowfall Days) have been made available to be selected and displayed as columns of the Selected Bridges Table. Therefore, these two attributes became available to be exported under Options.

  • Viewing UHPC and Timber Bridge Special Projects Data - The Data tabs for Special Projects including Ultra High-Performance Concrete (UHPC) and Timber Bridges have been updated.

  • Expanded Codes - The Export Data feature has been updated, so that all items of the downloaded data match the same formats/values as what is displayed in user interface.

  • Miscellaneous Bug Fixes - Several web interface and map bugs have been fixed in this release.
