Safe-D: Safety through Disruption

Automated Shuttles and Buses for All Users


Individuals using wheelchairs and those with limited or no sight face extra safety issues in the use of public transit, as well as personal vehicles, including getting to and from a bus or shuttle stop, getting on and off a vehicle, and being secure while riding in a vehicle. The demonstrations of automated shuttles and buses have included little or no participation by the disabled community. This project will address that gap by introducing individuals with disabilities to an automated shuttle in Arlington and a Smart Intersection in College Station, assessing their safety perception before and after riding in the shuttle and navigating the intersection and assessing information on their complete trip. The project will identify improvements in the vehicles, service operations, and the street system and built environment to ensure that individuals with disabilities have equal and safe access to automated shuttles and buses to improve their mobility.
