Abstract:The objectives of this study include developing condition assessment procedures, condition thresholds, and improvement plans for traffic signals in Illinois. This project first synthesized previous research and current practices of transportation agencies related to the management and lifespan expectations of traffic signals and their components. Interviews were then conducted with personnel familiar with traffic signal management practices in Illinois, and field work was conducted to identify refinements to then-proposed methods and condition thresholds. The project’s technical review panel also provided important guidance throughout the development of the assessment methods. The final recommendations included 34 assessments of traffic signal components. Pictures were included to demonstrate condition levels, and hyperlinks were included to guide reviewers to important online resources. The developed procedures support consistent evaluation of traffic signals throughout Illinois, provide a systematic process for public agencies to identify components in critical condition, and create the foundation to including traffic signals into asset management frameworks. Overall, implementing these procedures and standards should improve traffic signal performance due to reduced failures related to poor component conditions. Improved traffic signal performance is expected to reduce traffic signal life-cycle costs to Illinois Department of Transportation and improve traffic signal performance and safety for the traveling public.
