Abstract:

This report examines Long-Term Pavement Performance (LTPP) database users’ needs for traffic data and parameters and the extent of traffic data availability in the LTPP database. It identifies and recommends new analysis-ready traffic parameters and traffic data–usability indices for inclusion in the LTPP database. This report also presents a methodology for computation of analysis-ready traffic parameters selected by the Federal Highway Administration for this study and a methodology for assessing reasonableness of historical axle loading data included in LTPP database tables for sites that do not have sufficient information about the accuracy of equipment used to collect these data. This report includes a description of LTPP database tables that include newly computed analysis-ready traffic parameters. For LTPP sites that do not have traffic data, this report explores alternative data sources and provides recommendations for using these data sources. This report includes an overview of the User Guide for Selecting and Using Long-Term Pavement Performance Traffic Data, which aims to help LTPP database users navigate and understand LTPP traffic data and parameters and select or compute traffic parameters that best fit their project or analysis needs.
