Multi-Modal Intelligent Traffic Signal System (MMITSS)

A software system which utilizes vehicle-to-infrastructure communication to consider and balance signal priority requests from multiple vehicles approaching a traffic signal. MMITSS was originally developed at the University of Arizona for the Connected Vehicle Pooled Fund Study. UDOT modified the original MMITSS system to create the TSP and Signal Preemption systems used in Utah. The UDOT version of the software is referred to as MMITSS-Utah.
