Performance-based Operations Assessment of Adaptive Traffic Signal Control

Arterial management has been traditionally done using time-of-day mode. In recent years, adaptive controls have been implemented at congested arterials as an option to improve mobility by providing traffic-responsive control instead of implementing generic time-based timing plans. It is essential for a traffic engineer to perform a detailed before and after impact analysis of such a system to justify the cost of the system, better understand the workings and limitations of the system, and fine tune the system for the existing conditions. This analysis will benefit in investment programming of future potential corridors. This study will provide an evaluation of the adaptive traffic signal system to be installed along southeast (SE) 14th Street in Des Moines, Iowa and develop techniques for adaptive control evaluation and use them to evaluate the traffic adaptive signal system to be installed along Dodge Street in Omaha, Nebraska. The research team will work with the adaptive system supplier to capture data for the evaluation, eliminating hours of field data collection and also providing for a much more complete and longer time period of analysis. The analysis will also evaluate the potential of using wide-area probe-base data streams for batch performance analytics and real-time analytics. Given this is the first project of a new Iowa Department of Transportation (DOT) program, the timely results will highlight the benefits of such an investment and will serve as an important reference in consideration of the suitability and selection of similar projects across the state.
