In 2022, one in ninety-five people in the world were forcibly uprooted from their homes, causing them to seek homes in other countries—that is, become refugees. Resettlement in a new country allows them to escape unpredictable or unsafe conditions, but it comes with its own array of challenges. Though refugees’ satisfaction in their post-resettlement environments has been studied, the role of mobility in their qualities of life remains understudied. 

To fill this research gap, professors from the University of Arizona conducted a mixed-methods study with members of the refugee community Tucson, Arizona. Their goal was to understand how transportation impacts refugees’ well-being in order to develop recommendations for how cities and nonprofits can better serve this vulnerable portion of the population. The findings not only highlighted the importance of transportation to refugees and the number of barriers that prevent refugees from fully utilizing the systems in place, but also provided interesting insights into perspectives of transportation that challenge the traditional white feminist viewpoint of gender roles. They challenge the idea that the population of refugees can be generalized, and they place an emphasis on the importance of individual experiences.

The National Institute for Transportation and Communities (NITC) is proud to introduce a new Dissertation Fellow, Adrian Cottam of the University of Arizona. Cottam's doctoral research project, Machine Learning and Big Data-Based Approaches for Quality Freeway Volumes, will focus on improving the quality of freeway volumes and expanding their spatial availability.

"I was drawn to Transportation Engineering because it is a field where you can make major impacts to better your community. I found that by merging my passion for Computer Science with Transportation Engineering, I could use data to obtain more information on how local transportation could be improved through Intelligent Transportation Systems (ITS) and performance measurement. Throughout this process, I found that it was frequently a challenge obtaining high-quality data, or having access to data where you need it. This drove me to focus my dissertation on using machine learning techniques to improve data quality, and estimate traffic parameters where sensors were unavailable. My research is specifically focused on freeways, and seeks to use available data sources, such as crowdsourced data, to estimate data that isn’t always available. I am a firm believer in applied research, and hope to better my community through my research efforts. As such, I seek to develop methods that can be applied in a practical way, so...

Twelve students attending partner universities of the National Institute for Transportation and Communities (NITC) are receiving Eisenhower Fellowships presented by the U.S. Department of Transportation at this year's annual meeting of the Transportation Research Board (TRB). Meet the NITC Eisenhower Fellows:

Cameron Bennett, Portland State University

Cameron is a second-year master’s student in transportation engineering at PSU. His work as a graduate research assistant focuses on promoting and facilitating the uptake of active transportation modes. He serves as president of the PSU ITE-STEP (Students in Transportation Engineering and Planning) student group. He received Dwight David Eisenhower Transportation Fellowships presented by the U.S. Department of Transportation at the Transportation Research Board 2022 and 2023 annual meetings. He is also the...

When the COVID-19 pandemic first swept across North America and led to emergency shutdowns during the spring of 2020, the way people acquired food and household necessities was dramatically impacted. As stay-at-home orders minimized personal travel, transit services were reduced and many stores and restaurants either closed or modified their operations. 

Some of the gaps were filled by online retailers and delivery services. However, access to goods and services varied substantially depending on people's age, income level, and ability.

A new multi-university study funded by the National Institute for Transportation and Communities (NITC), the U.S. DOT-funded university transportation headquartered at Portland State University, and the National Science Foundation (NSF) captured how households responded as local, state, and federal governments imposed and lifted restrictions, brick-and-mortar establishments closed and reopened, and e-commerce and delivery services adjusted to the changing conditions.

The findings of this research are critical for emergency planning, but also for understanding the ever-changing mechanisms used to access retail and service opportunities (whether in person or online). The research identifies opportunities for future interventions to remedy barriers to accessing food, which will...
