Event Description

The MBTA would like bus riders' feedback on our Quantum mobility device securement system. We have started using the system in a pilot program on the Route 111 bus, but we’d like to get in-person feedback from riders. At this event, we will demonstrate Quantum—which secures riders' wheelchairs or mobility scooters to ensure their safety—at an outdoor session.

About the Quantum System

The fully automated Quantum system is an alternative to the MBTA's standard four-point manual securement system for keeping riders’ wheeled mobility devices in place. Quantum uses a robotic arm that deploys around a wheelchair's or mobility scooter's wheels and automatically adjusts its grip throughout the trip to ensure safety. The system also allows riders to independently secure and release their devices with the push of a button.
