THE DEVELOPMENT OF PERFORMANCE PREDICTION MODELS FOR VIRGINIA'S INTERSTATE HIGHWAY SYSTEM - VOLUME I: DATA BASE PREPARATION. FINAL REPORT

Performance prediction models are a key component of any well-designed pavement management 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. This volume, 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 nonhomogeneous 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. In addition, missing data items were secured from external sources and added to the data base. The problems encountered during this phase of the study suggested some desirable pavement management system features that would make prediction model development easier and more accurate.
