Pedestrian safety is critical to improving walkability in cities. To that end, NITC researchers have developed a system for collecting pedestrian behavior data using LiDAR sensors. Tested at two intersections in Texas and soon to be tested at another in Salt Lake City, Utah, the new software created by a multi-university research team is able to reliably observe pedestrian behavior and can help reduce conflicts between pedestrians and vehicles at signalized intersections. The Utah Department of Transportation (UDOT) is already working on implementing this new system to improve data collection at intersections.

The LiDAR system can especially improve multimodal travel at intersections with permissive left turns, which are indicated by a flashing yellow arrow. Previous research has shown that where a flashing yellow arrow, or FYA, is present, cars searching for a gap in traffic may not look for pedestrians. To remove the risk to people walking, some signals are programmed to turn off the FYA when a walk button is pushed. But...

Researchers Ivis Garcia, Sadika Maheruma Khan, and Kevin Fagundo-Ojeda of the University of Utah with Miriam Abelson and Nicholas Puczkowskyj of Portland State University have published a new article in the November 2022 issue of Transportation Research Part D: Transport and Environment.

Scholarship on gendered mobilities has shown that women experience transit differently than men do, particularly regarding personal safety. The article, "Harassment of low-income women on transit: A photovoice project in Oregon and Utah," makes a unique contribution to this body of literature because it shows that women feel targeted also based on their racial or ethnic identity and not only their gender. The article discusses women’s actions every day to increase their sense of safety.

Research has shown that low-income women who are...

How can community members become more engaged in transportation decision making?

Individuals and groups can learn to effect powerful change, but success requires some familiarity with how civic processes work. Community Transportation Academies, or CTAs, provide a basic technical understanding of how a city or region’s transportation system operates, along with the decision makers and decision-making processes that determine how the system is shaped.

Supported by the National Institute for Transportation and Communities (NITC), the new Wasatch Transportation Academy (WTA) at the University of Utah was piloted in 2022 in the Salt Lake City region. The research team developed a course vision, topics, and logistics for the WTA by interviewing stakeholders in the Utah Governor’s Office of Planning and Budget, the Utah Department of Transportation, the Utah Transit Authority, Salt Lake County, Salt Lake City, and the Wasatch Front Regional Council. Led by Nathan McNeil of Portland State University and Keith Bartholomew of the University of Utah, the WTA used the established Portland Traffic and Transportation class in Portland, Oregon as a framework.

How could a free transportation class for people living in the Salt Lake City region strengthen community conversations and advocacy around local priorities in transportation policy? Researchers at Portland State University (PSU) and University of Utah (UU) explored that question by bringing a well-known learning model from Portland, Oregon to SLC.

For over 25 years, the Portland Bureau of Transportation has partnered with PSU to offer the Portland Traffic and Transportation Course – a free 10-week course designed to provide local community members the skills and knowledge to participate in transportation decisions affecting their neighborhoods. This model has proven to be a success story in public agency-university partnership in community education. Building upon a 2015 project that documented the Portland course and developed a curriculum handbook, the National Institute for Transportation and Communities (NITC) has provided more funding for a pilot community transportation class–the Wasatch Transportation Academy– in Salt Lake, City Utah. Their first class was held on January 24, 2022 (view class recordings here) and ran through...

The National Institute for Transportation & Communities (NITC) research consortium, led by Portland State University, has awarded $530,419 in total funding for seven new research projects spanning five universities. With the extension of the FAST Act, NITC received one additional year of funding, and given this limited time frame, we emphasized projects that were relatively short in length, relied on existing expertise, and would yield specific outputs and outcomes. Several of the projects have an equity focus, and much of the research aims to make it easier to get around multimodally and/or by walking. The seven new projects are:

How can we use a variety of data-driven speed management strategies to make transportation safer and more efficient for all modes–whether you’re driving, walking or taking transit?

The project was led by Yao Jan Wu, director of the Smart Transportation Lab at the University of Arizona. Co-investigators were Xianfeng Terry Yang of the University of Utah, who researches traffic operations and modeling along with connected automated vehicles, and Sirisha Kothuri of Portland State University, whose research has focused on improving signal timing to better serve pedestrians. Join them on Sept 15, 2021 for a free webinar to learn more.

"We want to improve mobility for all users, be it pedestrians, vehicle drivers or transit riders, and there are different strategies to do this. How do we harness data to drive us to these strategies?" Kothuri said.

Funded by the National Institute for Transportation and Communities (NITC), this multi-university collaboration addressed the question from three angles:

  • Wu and his students in Arizona looked at the impact of speed management strategies on conventional roadways...

Research demonstrates that marginalized populations experience significant barriers in accessing transit. The Transportation Research and Education Center (TREC) and the Homelessness Research & Action Collaborative (HRAC) at Portland State University are working with the University of Utah in a project funded by the National Institute for Transportation and Communities (NITC) to understand how people from selected historically marginalized communities experience discrimination and harassment on transit and in public areas such as sidewalks, bus stops, and transit platforms when accessing transit.

The study will be conducted in two sites: Portland, Oregon and Salt Lake City, Utah. In Portland, the study population will include racially and ethnically diverse people experiencing homelessness and people who identify as transgender and gender nonconforming; and ride TriMet. In Salt Lake City, the study population will include people experiencing homelessness as well as diverse groups based on their gender, racial, and ethnic identity; who ride Utah Transit Authority. We are seeking transit riders to help inform the study through photos and interviews. Participants will be compensated up to $50 for their labor. The researchers will be recruiting participants for this study through the end of August.

Led by Xiaoyue Cathy Liu of the University of Utah (UU) and funded by the National Institute for Transportation and Communities, researchers have created a web-based modeling tool (see GitHub repository built for the Utah Transit Authority) that enables U.S. transit providers to explore the impacts of changing over their systems to electric buses*. The researchers ran the model for TriMet in Portland, OR as well, with TriMet results and analysis presented in the final report (PDF).

"The interactive visualization platform lets users explore various electric bus deployment budget scenarios, so that transit agencies can plan the most cost-effective way to transition their fleet from diesel to electric buses – while prioritizing disadvantaged populations," Liu said.

The research team, at University of Utah, Portland State University (PSU), and University of California, Riverside, set out to answer three questions: 

  1. What costs and benefits are associated...

The National Institute for Transportation and Communities (NITC) program has released its 2020 general research request for proposals. Faculty at NITC's partner universities* are invited to submit abstracts by March 23, 2020.


Through funding provided by the U.S. DOT, we will award up to $1,000,000 to research projects that support NITC’s theme: improving mobility of people and goods to build strong communities. Our theme includes a few key topics:

Increasing access to opportunities.

Well-connected regions and communities can improve social equity by providing access to jobs, services, recreation, and social opportunities. Research should examine barriers to access, including the connections between transportation, land use, and housing. It should look at how to overcome these barriers and improve accessibility, affordability, and equity in our communities.

Improving multi-modal planning and shared use of infrastructure.

Improved mobility requires a range of options for moving people and goods. As concepts of mobility evolve, research is needed to understand how people and firms make mode choices so that we can design better multi-modal systems. Research should examine how...
