Computer programs developed for analyzing signalized intersections continue to grow in their popularity and use by many transportation professionals. These programs differ not only in the features or options available, but the programs also differ in certain underlying assumptions of the models used in estimating various measures of effectiveness. These differences make some programs more appropriate than others when the features and underlying assumptions are evaluated for their compatibility to the type of analysis being performed and the type of intersection being analyzed. The selection of the most appropriate program for performing intersection analysis has direct implications on the success of congestion This paper describes an expert system that can be used to select the most appropriate intersection analysis model. The system was developed using knowledge or experience obtained from experts in traffic engineering who have a great deal of familiarity with signalized intersection analysis programs and understand their abilities and limitations.
