Traffic signal control has experienced very few fundamental improvements in the past 50 years. This project aims to change that by developing a Multi-Modal Intelligent Traffic Signal System (MMITSS) which will integrate information from a variety of sources, including connected vehicles, to improve traffic control systems, making them better performing and safer for pedestrians and vehicles alike. The Phase I effort developed a concept of operations, system requirements, and 28 system components that are now being developed in Phase II. Now underway, Phase II will involve designing and testing each system component and integrating them into one cohesive system. A formal demonstration aimed at highlighting the functionality and capability of MMITSS is schedule for later this year.
