More than 1 million people live in the greater Tucson region, and though most of them have access to a vehicle, a variety of transportation options are available. In addition to developing transportation plans that help deliver a safe, reliable and efficient transportation system, Pima Association of Governments manages programs that help to reduce traffic congestion and support cleaner air. From mass transit options, ridesharing and other travel reduction efforts to newer transportation methods such as app-based ride hailing, electric and automated vehicles, our planning efforts look to the future of travel. Southern Arizona offers many transportation offerings, including air travel and railroad service.
