LTPP Data Analysis Plan
The LTPP Data Analysis Plan allows easy access to proposed and active research projects, and projects that have been completed along with their final reports. The List View allows users to view and order research reports based on different attributes and selection criteria. The Pivot View allows users to find research projects based on selected criteria. Since 1999, the analysis of the LTPP data has been guided by the “Strategic Plan for Long-Term Pavement Performance Data Analysis.” The plan sets forth seven strategic objectives supporting the goal to develop knowledge, performance relationships, and models to facilitate improved pavement design and reliable predictions. Each strategic objective, in turn, is supported by several focused "product objectives," which are color-coded to represent criticality and numbered to indicate sequencing for completion. In 2010, a LTPP Pavement Analysis Forum was held to review and refine targeted analytical outcomes under the strategic plan. During the pavement analysis forum, the 2010 Strategic Plan was expanded to include two new strategic objectives. Formerly known as the Strategic Plan for LTPP Data Analysis with 9 objectives, the newly formed LTPP Data Analysis Plan now has 5 objectives with revised analytical outcomes and newly proposed analysis projects as a result of the 2020 LTPP Pavement Data Analysis Workshop. The LTPP program is implementing this plan and it can be viewed below.
