Automated Data Collection and Analysis for Arterial Traffic Operations (Phase 1 - 5)

PM: Diahn Swartz, P.E.

In 2018, Marana equipped traffic signals with video detection sensors that were configured to collect traffic data according to parameters consistent to studies conducted in the City of Tucson. The event data from these sensors are processed using algorithms developed by the UArizona to determine occupancy and delay at traffic signals to estimate travel speeds. These metrics can be used to evaluate measures to improve the efficiency of traffic signals and corridors. The overall goal of this multi-year collaboration is to facilitate data collection and analytics and develop data-driven solutions that provide efficient traffic signal operations and optimal progression along key corridors within the entire Town of Marana. Efficient traffic operations save time and money, and positions the Town for future investment in business and technology.
