Strategic Plan for LTPP Data Analysis: Since 1999, analysis of the LTPP data at the national level has been guided by the Strategic Plan for Data Analysis. The Strategic Plan was developed by the TRB Expert Task Group on LTPP Data Analysis, recommended by the TRB LTPP Committee, and adopted by FHWA as the basis for selecting LTPP analysis projects and evaluating progress in LTPP data analysis. www.fhwa.dot.gov/pavement/ltpp/stratplan/strategic.cfm
ASCE-LTPP International Contest on LTPP Data Analysis: The contest is designed to encourage university students, professors, and highway department engineers from around the world to get involved in using the LTPP database. www.fhwa.dot.gov/pavement/ltpp/contest.cfm
SPS Traffic Data Collection Pooled Fund Study: This study includes two phases. Phase I consists of assessing, evaluating, and calibrating the current weigh-in-motion and vehicle classification systems used to collect traffic data at SPS sites across the country. Phase II consists of installing and maintaining new weigh-in-motion equipment as necessary to ensure high-quality data collection.
