Automated Pavement Evaluation System for Pavement Distress Assessment

摘要

The paper describes work performed for the Connecticut Department ofTransportation (ConnDOT) to automate the evaluation of pavement distress images. In 1983, the ConnDOT began developing a pavement management system for state-maintained highway. The basis for the pavement rating system is ConnDOT's photologging system in which a series of photographs of the pavement surface is stored on laser videodiscs and later used to assign pavement condition scores for maintenance purposes. The rating scheme currently being used by ConnDOT is based on manual evaluation in which raters view all sections of pavement images on a monitor and count distress features. This manual rating process is extremely time consuming and tedious.
