Ariz.'s Sun Tran Adds Q'Straint Quantum Securement Systems

Q'STRAINT/Sun Tran
Riders in Tucson, Ariz., using mobility devices can now enjoy an enhanced experience on Sun Tran buses. Q’STRAINT’s Quantum Automatic Securement Stations are currently available in 79 buses, or 40% of the active fleet. These new stations replace straps that were previously used to secure mobility devices. Now all it takes is the push of a button and a snap of the seat belt for riders to self-secure their wheelchair, scooter, or other mobility device.
“This technology promotes independence among our riders with mobility devices who can now be in control of securing themselves,” said Jeff Rock, Sun Tran asst. GM. “It also benefits other riders because it shortens the boarding times at bus stops, allowing all riders to get where they need to go quickly and efficiently.”
Riders using the technology are encouraged to provide feedback about their experience to help Sun Tran measure the impact of this upgrade. Researchers from the University of Arizona created a survey that riders can take online now through the end of September.
The technology upgrade was set in motion by a grant from the Federal Transit Administration awarded in 2021. Along with a fare analysis study and the implementation of contactless solutions onboard buses, Sun Tran used part of the $600,000 grant to pay for 41 securement stations.
“Initially, we looked at the Quantum devices as a way to allow for social distancing at the height of the COVID-19 pandemic,” said Rock. “Now we are discovering bonus benefits and the survey could uncover even more ways this technology is making life easier for members of our community.”
The Quantum stations will come standard in all new buses Sun Tran acquires. Traditional strap securement areas also remain available.
