Architecture for Active Management of Geographically Distributed Signal Systems

This article describes the active traffic signal management practices that Indiana has implemented to reduce delays caused by improper traffic signal timings. Indiana has adapted the concepts of six sigma business strategies (define, measure, analyze, improve and control) for active traffic management. These concepts provide a data-driven systems engineering perspective for identifying challenges in active traffic management. Indiana is modernizing traffic signal management architectures by leveraging commercial data services, National Cooperative Highway Research Program 3-79a performance measures and high-resolution controller data logging. Examples are provided to highlight the implementation of this modernization for traffic signal operations and maintenance. This architecture has been expanded to 34 intersections thus far, and will be expanded to more than 100 in 2011.
