Development of Performance Prediction Models for Virginia's Interstate HighwaySystem. Volume 1. Data Base Preparation

摘要

Performance prediction models are a key component of any well-designed pavementmanagement system. In this study, data compiled from condition surveys conducted annually on Virginia's pavement network were used to develop prediction models for modeling the interstate system. The study is reported in two volumes. Volume I describes the task of preparing the data base for model development. At the onset, several problems challenged the modeling effort: a data base containing nonhomogenous sections unsuitable for use in modeling, a user-unfriendly system incapable of efficient data manipulation, and missing and incorrect data. A methodology was devised to address these limitations, involving the development of a number of computer programs to process, merge, and screen the data files.
