Abstract

The safety of signalized expressway intersections has been the focus of prior research. These efforts have yielded results that were either inconclusive or required further investigation. This thesis presents the application of case-based reasoning to the issue. Similar intersections and crash reduction factors (CRFs) are used to establish expected crash performance for a candidate intersection. A spreadsheet based tool is developed that compares candidate intersections to these comparison sites. The tool uses expert opinions, attribute weights, and crash reduction factors to assist in the decision to signalize a site, to compare performance of existing signalized intersections to similar sites, or to explore the potential safety effects of intersection modification or changes in traffic patterns.
