Users can then apply region selection tools and customizable markers to see “data within the data” and even zoom in to street views and photos of the bridge where available. Query results can be displayed in 1-D or 2-D charts and graphs, as map graphs, or in a GIS interface that superimposes the data on Google Maps. In the end you still wouldn’t have a good picture of the query results or a good way to communicate them.ĭata visualization is where the portal really outshines any other bridge performance tool available. Comparing/contrasting bridge attributes and locations, analyzing individual bridges, or seeing patterns within the results would be an arduous task. How many of those received a “poor” condition rating on at least 30 percent of the deck upon last inspection? How many are steel girder construction versus box girder? What is the inspection history for each bridge on I-95 in those three states?Įven if you know where to look, sifting through multiple databases or spreadsheets to extract all the information you want could take hours. Let’s say you want to know how many bridges in Virginia, Maryland, and Delaware are at least 60 feet long, 25 years old or older, and have average daily traffic volumes greater than 5,000 vehicles. Since the portal pulls from multiple resources, users get exhaustive query results and the ability to drill down to a micro level. It even has a function that can calculate deterioration curves based on historical data. In a single intuitive web environment, users can query the system via simple or advanced searches using built-in filters and get tailored, comprehensive answers at lightning speed. The LTBP Bridge Portal is a very powerful tool with a deceptively simple, customizable user interface and options not available in any one dataset it draws from. Combined, these data encompass nearly every characteristic and biographic fact that can influence bridge performance: construction, design, age, dimensions, elevation, weather data, traffic data, weigh-in-motion data, maintenance/repair records, and more. Through this UTC-FHWA collaboration, CAIT created the LTBP Bridge Portal, a new web-based product that comprises bridge information mined from a wide range of datasets. The Center for Advanced Infrastructure and Transportation (CAIT) at Rutgers, the State University of New Jersey, was competitively selected as the primary university partner on LTBP and, for the last 8 years, has been working with FHWA to provide a detailed and timely picture of bridge performance. bridges-our transportation network’s most critical links. In 2008 the Federal Highway Administration (FHWA) launched its largest and most robust bridge research endeavor, the Long-Term Bridge Performance (LTBP) Program, a 20-year study of U.S.
