This report describes an evaluation study of the recently installed computer-based traffic signal control system in New Orleans, Louisiana. The evaluation effort focused on two primary areas: on-street measures of performance, (e.g., is traffic moving more efficiently with the new system than with the old) and, system operations measures of performance, (e.g., do the real-time surveillance, equipment monitoring, and control capabilities result in tangible improvements when compared to that which could be achieved with a conventional system). Emphasis in the study is also placed on the application of UTCS first generation software to control traffic on arterial roadways. The results showed that the two computer based alternatives that were evaluated provided significant improvements in performance with respect to the base case. The time-of-day alternative resulted in an average of 8.8 percent reduction in total vehicle-minutes of network travel during a 14-hour period of each day tested. The traffic responsive alternative provided an 8.5 percent reduction. In addition to this technical report, an executive summary was prepared. /FHWA/
