Using High-Resolution Bus Detection Data to Improve Travel Time Prediction and Identify Urban Congestion Spots

Miguel Andres Figliozzi Robert Bertini
Transit travel time, operating speed and reliability all influence service attractiveness, operating cost and system efficiency. These metrics have a long-term impact on system effectiveness through a change in ridership. As part of its bus dispatch system (BDS), the Tri-County Metropolitan Transportation District of Oregon (TriMet) has been archiving automatic vehicle location (AVL) and automatic passenger count (APC) data for all bus trips at the stop level since 1997. In 2014, a new and… Read More

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… Read More
