Abstract

This paper synthesizes traffic data and statistical parameters available through the Long-Term Pavement Performance Program (LTPP), provides recommendations to pavement engineers and researchers about the traffic parameters most suitable for different pavement analyses, and identifies LTPP database tables containing such parameters. The paper also contains information about LTPP traffic data collection methods and recommendations for assessing the rationality of truck weight data collected by weigh-in-motion (WIM) equipment. In summary, this paper was developed to highlight the wealth of truck traffic data available through LTPP and to serve as a resource document for pavement researchers, designers, and transportation planning professionals interested in LTPP truck traffic data and summary parameters characterizing truck traffic.
