The Intelligent Transportation Systems and Signal Design Section operates the Regional Traffic Operations Center (RTOC). The RTOC communicates to and controls all City of Tucson traffic signals. In addition, they work with the other jurisdictions in the area including the Arizona Department of Transportation, Pima County, Town of Marana, Oro Valley and City of South Tucson connecting their signals to the city system to provide a seamless transportation system in the valley. They manage the traffic volume and turning movement count programs for the Division along with warranting studies done to determine the need for future traffic signals or left turn arrows. This section also plays an active role in TDOT's capital improvement program by providing plans, specifications and estimates for new signal and street light installations, assisting consultants in the review and preparation of plans and specifications and providing guidance and clarification during the construction phases.
