dc.description.abstractLong-Term Pavement Performance (LTPP) InfoPave is the web interface for the world's largest pavement performance database. This web interface is being developed under the Federal Highway Administration (FHWA) LTPP program to achieve the strategic goal of utilizing LTPP data effectively. An effective web interface helps reach users crossing all levels of expertise and geographical boundaries and helps information sharing which adds value to tax payers' dollars. To overcome the hurdles for easy data access, the initial phase of the LTPP InfoPave development considered effective ways of data design including organizing the data for the user, expanding data to the unit (test section) level, developing consistent terminology and metadata, and using familiar pavement engineering names for tables and fields in the database. The design of the data warehouse and development of feature mechanisms were centered on the efficient data structure model. Feedback obtained at each major step of development helped create this web interface. LTPP InfoPave, released during the 93rd annual meeting of the Transportation Research Board (TRB) in January 2014, has received positive response from students, researchers, State DOT engineers, and stakeholders alike. The second release of InfoPave in January 2015 includes major enhancements to existing features and a series of new features, which implement novel visualization tools to further facilitate access to LTPP data. The application of LTPP InfoPave enhances data visualizing, selection, and access. This paper will layout data analysis examples, which demonstrate the utility of InfoPave in providing answers to pavement performance questions. Plans for future improvements and implementation will be discussed as well.en
