Using Performance Measures To Improve Signal System Performance, Ross Haseman, Christopher Day, Darcy Bullock

Indiana Local Technical Assistance Program (LTAP) Technical Reports

Recent emphasis on improving signal system performance has prompted research on the collection of enhanced quantitative data for making operational decisions, the development of a systematic method for monitoring and recording system performance and the definition of quantitative performance measures to identify opportunities to improve corridor traffic operations. This document summarizes the highlights from several publications which document the motivation, theory and application of traffic signal performance measures. Topics discussed include the advantages of monitoring signal system performance without labor intensive field observations. The benefits of real time monitoring and evaluation of signal system performance as well as system troubleshooting. …
