Project Details

Project Description: 

The standard data release (SDR) is the annual release of the Long-Term Pavement Performance (LTPP) program database. SDR is available annually to the public in Microsoft Access® format and available on Digital Versatile Discs (DVD) and/or Universal Serial Bus (USB) drives. SDR can be obtained through Long-Term Pavement Performance (LTPP) customer support services at ltppinfo@dot.gov. Perhaps one of the most useful documents contained here for beginners is the tutorial "Accessing LTPP Data," which includes step-by-step examples of working with the standard data release (SDR) in Microsoft Access and building queries for data extraction. The first document to read is the "Release Notes," which comes in hardcopy and electronic format with the SDR. These notes contain important information about organization, content, and significant changes that have occurred from release to release. A Reference Library DVD Read-Only Memory (ROM) accompanies the Standard Data Release and gives the user the capability to search for software utilities, resource documents, and research reports that support the database.

Goals

The Long-Term Pavement Performance (LTPP) program makes the world's largest pavement performance database available annually to the public in Microsoft Access® format and available on digital versatile discs (DVDs) and/or Universal Serial Bus (USB) drives.
