Expert Task Group on LTPP Traffic Data Collection and Analysis

项目名称：	Expert Task Group on LTPP Traffic Data Collection and Analysis
摘要：	The Transportation Research Board (TRB) Long-Term Pavement Performance Committee, acting through the National Research Council, will advise the Federal Highway Administration (FHWA) and the American Association of State Highway and Transportation Officials (AASHTO) on the planning and execution of the Long-Term Pavement Performance (LTPP) studies. The LTPP studies are a set of operational activities consisting of gathering and analyzing data that is being collected on more than 2000 in-service pavements in the United States and Canada. The principal objective of this data collection and analysis is to further the understanding of how and why pavements deteriorate when subjected to traffic loadings and environmental conditions. Data collection and analysis began in 1987 and will continue through 2009. The committee will also prepare reports, including letter reports, containing the committee's evaluations and suggested mechanisms to enhance the utility to the states of the studies' outcomes.
