  • Smart Transportation

    Smart transportation refers to the integrated application of modern technologies and management strategies to optimize transportation systems. These include:
    • Mobility on demand (MOD) technologies assisting travelers in reducing travel time, system costs, fuel consumption and enhancing safety
    • Intelligent technologies optimizing signal timing and other infrastructure based on need such as ramp metering, transit signal priority and lane shifting
    • Real-time transportation system updates to vary speed limits or road closures based on weather or emergency conditions
    • Improving freight efficiency
    • Rendering the multi-modal public transportation more convenient and reliable

    Imagine an app on your smartphone that will pay you $ incentives to:

    • Reduce your travel timeTNMS
    • Increase your travel safety
    • Reduce your fuel consumption
    • Decrease your travel costs
    • Improve air quality

    Sounds too good to be true?  Welcome to the world of Mobility on Demand (MOD)!  MOD allows local jurisdictions to invest in traveler mobility benefits at a fraction of the cost of expanding roadway capacity.

    See how Pima County intends to connect MOD apps to infrastructure under our Connected Vehicles tab.

    The Connected Vehicle Program led by the USDOT is working with transportation agencies, vehicle and device manufacturers to test and evaluate technologies that will enable cars, buses, trucks, trains and infrastructure to “talk” to one another so as to optimize both mobility and safety.

    Modeling the transportation system allows us to evaluate different scenarios such as expanding roadways, road diets and Mobility on Demand strategies to see which offer the best return on investment.

    To this end, Pima County has partnered with the University of Arizona College of Engineering to build a Dynamic Traffic Assignment (DTA) model for the region so we can simulate different scenarios and compare costs among alternatives.
