LONG-TERM PAVEMENT PERFORMANCE INFORMATION MANAGEMENT SYSTEM: DATA USERS GUIDE

The Long-Term Pavement Performance (LTPP) Information Management System (IMS) Data Users Guide provides an overview of the Information Management System of the LTPP Program that was initiated under the Strategic Highway Research Program (SHRP) and is currently managed by the LTPP Division of the Federal Highway Administration. This document is aimed to assist the researchers in understanding the types of data collected under the LTPP Program, how to request the data, the available formats of the IMS data, and how to use the output from the data base. The Guide also briefly describes the background of the LTPP Program, the data flow through the IMS, the data quality control checks, and sample reports generated from the LTPP data.
