Expanding Transmobilities: An Art-Informed Methodology For Genderdiverse Travel Behavior
Nicholas Puczkowskyj
There is a significant gendered travel behavior research gap in the transportation literature. A plethora of transportation literature identifying and contrasting cisgender disparities exists, but more inclusive approaches to genderdiverse identities remain scarce. The burgeoning field of transmobilities investigates transgender mobility and evolved from the nexus of mobility justice and gender studies by studying transgender experiences on public transit. This dissertation expands transmobil...

BACKGROUND
One of the most common locations for fatal motor vehicle-bicyclist crashes is at intersections, which inherently have a large number of turning conflicts. Reducing these conflicts is a key objective in improving intersection safety across all modes. Of particular concern for bicyclists’ safety at intersections are the conflicts between straight-through bicyclists and motor vehicle right-turns and opposing left-turns. Despite the widespread acknowledgement of this problem, trans...
