Performance Measures For Local Agency Traffic Signals, Jay Grossman, Darcy M. Bullock
Performance Measures For Local Agency Traffic Signals, Jay Grossman, Darcy M. Bullock
Indiana Local Technical Assistance Program (LTAP) Technical Reports
The project focused on accelerating implementation of research recommendations emerging from traffic signal research projects conducted by the National Cooperative Research Program and Indiana Department of Transportation. This project developed specification language that was subsequently used in procurements in Elkhart County, IN; Lafayette, IN; and Morgantown, WV. The performance measures specified in Appendix A and subsequently deployed in Elkhart County, IN, and Lafayette, IN, were the first commercial deployment of real-time traffic signal performance measures recommended by NCHRP 3-79a. The deployment in Lafayette, IN, received an ACEC award in March 2012. In addition to accelerating implementation, this research project examined …

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. …
