A procedure is presented to prioritize operational improvements for signalized intersections based on a cost-effectiveness analysis. The measure of effectiveness used is the estimated reduction in person-hours of stopped delay resulting from the improvements. The procedure was developed to provide technical assistance in the evaluation of short- to medium-term improvement alternatives and to aid Capital Improvement Program (CIP) development. This procedure represents the second level in a two-level analysis process. The first-level analysis is a deficiency index to identify the intersections most in need of improvement. The application of the procedure is demonstrated through the evaluation of improvement alternatives for 30 intersections in Tucson, Arizona. These intersections were identified as being the most operationally deficient based on the first-level deficiency analysis. The procedure is easily applied through the aid of a computer spreadsheet. The procedure facilitates the selection between alternatives at a single location and the ranking and selection of improvements for inclusion in a local CIP considering budget constraints.
