New mobility technologies, such as shared mobility services and autonomous vehicles (AVs), continue to evolve. How do travelers decide whether to adopt new transportation modes or continue to use conventional modes? "Transportation Mode Choice Behavior in the Era of Autonomous Vehicles: The Application of Discrete Choice Modeling and Machine Learning" is a 2022 dissertation by Sangwan Lee of Portland State University which uses machine learning to examine this question.

Lee, who earned his PhD from the Nohad A. Toulan School of Urban Studies and Planning in 2022 working with faculty advisor Liming Wang, is now a research associate working in employment research at LX Spatial Information Research Institute, Korea Land and Geospatial Informatix Corporation in Jeonju, South Korea. He is currently working on several…

The 102nd annual meeting of the Transportation Research Board (TRB) will be held January 8–12, 2023 in Washington, D.C., and ten of Portland State University's core transportation faculty and researchers will be sharing their expertise at the largest transportation conference in the world. The TRB annual meeting attracts thousands of transportation professionals from around the globe to address transportation policy, practice, and plans for the future.

The spotlight theme for the 2023 meeting is Rejuvenation Out of Disruption: Envisioning a Transportation System for a Dynamic Future.

The National Institute for Transportation and Communities (NITC) is proud to introduce our newest Dissertation Fellow, Nicholas Puczkowskyj of Portland State University, who was awarded $15,000 for his doctoral research project: Expanding Transmobilities: An Art-Informed Methodology For Genderdiverse Travel Behavior.

"My dissertation focuses on understanding how genderdiverse individuals' gender identity influences their travel behavior and travel decisions. I use an art-based methodology by operationalizing collage and mental maps to delicately capture these data. I believe this work will support mobility justice research and the greater social justice movement by further solidifying the field of transmobilities. Additionally, this research seeks to push the boundaries of transportation research by illustrating the power of art as a modality for travel behavior research," Puczkowskyj said.…

If you're biking through Cincinnati, Ohio in the next couple of years and find yourself pedaling on a Portland-style neighborhood greenway or two-way protected bike lane, it might be because two engineers from the City of Cincinnati's Department of Transportation & Engineering—Joe Conway and Brian Goubeaux—attended our Comprehensive Bikeway Design Workshop in the summer of 2022 and brought some inspiration home.

The City of Cincinnati is in the process of updating its…

Navigating an unfamiliar place is uniquely challenging for people with disabilities. People with blindness, deafblindness, visual impairment or low vision, as well as those who use wheelchairs, can travel more independently in urban areas with the aid of effective wayfinding technology. A new report from the National Institute for Transportation and Communities (NITC) explores how to leverage low-cost methods to enable people to more easily move through public, urban indoor and outdoor spaces.

The study, led by Martin Swobodzinski and Amy Parker of Portland State University, used focus groups, two case studies, and an in-person structured wayfinding experience on the PSU campus to find the most helpful ways of getting around. Tactile maps were found to be a very useful resource, with an accessible mobile app also showing promise as an orientation and mobility aid.

The researcher will share more details about this project in a…
