Research on older adults frequently explores the notion of “aging in place”—providing older adults the opportunity to continue to live in their own homes and communities. However one’s ability to stay or leave, particularly in old age, often depends on the built environment. An accessible neighborhood that prioritizes mobility affords the ability to meet basic needs like goods, services, and social activities.

Tell us about yourself?

I’m a second year dual master’s student in city and metropolitan planning and real estate development at the University of Utah. I came to Utah via New York City where I spent 6 years working in the nonprofit sector. Prior to that, I did community development in the U.S. Peace Corps for two and a half years in Mauritania and Mozambique. Utah is an exciting place to study planning, transportation, and development because the population is growing and the built environment is changing so fast. I became interested in transportation and our (unhealthy) relationship with cars at a young age growing up in Los Angeles. Now that I’m in Salt Lake City, I’m focused on researching and creating more sustainable relationships between transportation and land management.

What (or who) has influenced your career path in transportation?

As I mentioned, I grew up in Los Angeles, and went to undergrad in Orange County. I formed my early impressions of transportation...

The National Institute for Transportation and Communities (NITC) program has released its 2019 general research request for proposals. Faculty at NITC's partner universities* are invited to submit abstracts by March 29, 2019.


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
  • Improving multi-modal planning and shared use of infrastructure
  • Advancing innovation and smart cities
  • Developing data, models, and tools

2019 RESEARCH PRIORITIES

The NITC Advisory Board has provided input into several research priorities that relate to multimodal transportation data and the transportation-land use-housing connection. NITC is prioritizing the funding of proposals that directly addresses research questions related to:

Developing Data, Models and Tools. Agencies are confronting a plethora of new mobility options along with new data sources to support transportation research, planning, and analysis. Several priority research areas have been identified to increase understanding: 

  • Collection of multimodal...

It can be expected that automated vehicles and human-driven vehicles will coexist in the transportation network for quite some time. In order to support various traffic control tasks it is critical to develop a reliable model to understand the real-time traffic patterns in this mixed environment. A new report from the National Institute for Transportation and Communities (NITC) contributes three new tools to help planners model freeway traffic with both connected automated vehicles (CAVs) and human-driven vehicles (HVs).

The project was led by Xianfeng (Terry) Yang, an assistant professor of civil and environmental engineering at the University of Utah, with...

Webinar: Modeling Freeway Traffic in a Mixed Environment: Connected and Human-Driven Vehicles - Terry Yang

OVERVIEW

Although connected vehicles (CVs) will soon go beyond testbeds, CVs and human-driven vehicles (HVs) will co-exist over a long period. Hence, it is critical to consider the interactions between these two types of vehicles in traffic flow modeling. In this study, we aim to develop a macroscopic model to understand how CVs would impact HVs in the traffic stream. Grounded on the second-order traffic flow model, we study the relationships among flow, density, and speed by two sets of formulations for the groups of CVs and HVs, respectively. A set of friction factors, which indicate CVs' impact to HVs, are introduced to the speed equation for accounting CV speed impacts. Then extended Kalman Filter is employed to update both model parameters and friction factors in real-time. By using CVs trajectory data as measurements, the difference between CV average speed and overall traffic mean speed will be fully accounted. The proposed model will serve as a basis for designing CV-based traffic...

The latest Small Starts Grant projects, selected by NITC's executive committee, will explore equitable access to mobility options, communicating the applied value of GPS data to agencies, and transportation resiliency in natural disasters.

This annual NITC funding program is a unique opportunity to tackle small-scale ($20,000 or less in scope) research projects. In contrast to our larger, annual flagship program ($30–150K), Small Starts enables us to include researchers who:

  • Bring a diverse, interdisciplinary perspective and may not have considered applying a transportation lens to their work before.
  • Offer a new voice in the field, whether they’re untenured faculty or a researcher who has not received a NITC grant before.
  • Seek to kick-start a larger project by first tackling an exploratory study smaller in scope.
THE NEW PROJECTS

The new projects represent a mix of topics and disciplines across our partner campuses, aimed at supporting and advancing mobility with a focus on creating equitable transportation options. These projects total $60,000 in funding for this round.

People talking and looking at materials in a workshop
Sep 20, 2018

We held our annual flagship professional development event, Transportation & Communities, on September 13 and 14. In honor of the event's ten-year anniversary, we changed up the format: Rather than a typical conference with one-hour sessions and a keynote gathering, we offered a selection of intensive half-day workshops. See photos from the event.

The workshops gave practitioners a chance to take a deep dive into new skills in order to walk away with new tools or frameworks that could be applied to their work. We offered a review of congestion mitigation strategies, universal access and equity in pedestrian planning, and discussion on how smart technology could be implemented in suburban communities. Several workshops were based on findings from new research by the National Institute for Transportation & Communities (NITC), the six-university consortium which sponsored the event. The NITC...
