Book excerpt: This report documents the results of two completed Phase I tasks for the project titled, "Evaluation and Development of Pavement Scores, Performance Models and Needs Estimates". These tasks involved a literature review and a review of the current Texas Pavement Management Information System (PMIS) score process. The objective of the project is to develop improvements to PMIS to meet the needs of the Texas Department of Transportation (TxDOT). The project is split into three phases. Phase I involves a review of the current PMIS and recommendations for modifying and improving analytical processes in the system. Phase II involves developing pavement performance models for the system. Finally, Phase III involves developing improved decision trees for the system's needs estimate process. The first project task involved developing a synthesis on how states define and measure pavement scores: that synthesis was published in February 2009. The other Phase I tasks for this project are currently ongoing; the results of all remaining tasks will be documented in the final report for this project.
