We've collected posters and presentations of NITC research at TRB. Explore the links below to see what NITC researchers brought to D.C. this year—the below projects have a connection to NITC funding, but are not necessarily representative of the full body of work that researchers at these institutions brought to the annual meeting.

Webinar: Visual Exploration of Trajectory Data
Feb 03, 2020
 

PRESENTATION ARCHIVE

OVERVIEW

This webinar will demonstrate the tremendous value of GPS trajectory data in understanding statewide travel patterns and measuring performance. First, Dr. Markovic (U of Utah) will conduct visual exploration of GPS trajectories that capture about 3% of all the trips in Utah. He will briefly discuss the problem of scaling GPS trajectories to the population, and then focus on the use of scaled trajectories in computing origin-destination matrices, vehicle-hours delays, vehicle-miles traveled, and trip-based performance measures. Second, Dr. Franz (CATT Lab) will demonstrate a suite of visual analytics that enables transportation agencies to easily explore terabytes of GPS trajectory data. He will demonstrate different tools and share the experience of 5 state DOTs that are currently using CATT Lab's trajectory data suite.

KEY LEARNING OUTCOMES

  • Trajectory data represents the most complete vehicle-probe data and provides unprecedented opportunity for transportation system analysis.
  • Transportation agencies can easily leverage visual analytics to obtain insights in statewide traffic patterns and performance measures.

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...

New Travel Demand Models
Dec 18, 2019

PRESENTATION ARCHIVE

OVERVIEW

Conventional four-step travel demand models are used by nearly all metropolitan planning organizations (MPOs), state departments of transportation, and local planning agencies, as the basis for long-range transportation planning in the United States. A flaw of the four-step model is its relative insensitivity to the so-called D variables. The D variables are characteristics of the built environment that are known to affect travel behavior. The Ds are development density, land use diversity, street network design, destination accessibility, and distance to transit. In this seminar, we will explain how we developed a vehicle ownership model (car shedding model), an intrazonal travel model (internal capture model), and mode choice model that consider all of the D variables based on household travel surveys and built environmental data for 32, 31, and 29 regions, respectively, validates the models, and demonstrates that the models have far better predictive accuracy than Wasatch Front Regional Council (WFRC)/Mountailand Association of Governments’ (MAG) current models.

In this webinar, researchers Reid Ewing and Sadegh Sabouri will demonstrate the effectiveness of the new...

Our National Institute for Transportation & Communities (NITC) research program has awarded grant funding for a new series of Small Starts projects.

The latest Small Starts Grant projects, evaluated by the NITC Advisory Board and selected by NITC's Executive Committee, will explore mobility impacts of construction workzones, transportation equity and barriers for low-income travelers, and the widespread impacts of emerging technologies like e-scooters and ride hailing.

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

  • Offer a new voice in the field, whether they’re untenured faculty or a researcher who has not received a NITC grant before

  • Want to kick-start a larger project by first tackling an exploratory study smaller in scope

Conventional four-step travel demand modeling is overdue for a major update. The latest NITC report from the University of Utah offers planners better predictive accuracy through an improved model, allowing for much greater sensitivity to new variables that affect travel behavior. Specifically, it accounts for varying rates of vehicle ownership, intrazonal travel, and multimodal mode...

Byron Head
Oct 09, 2019

Byron Head is a masters student in the department of City and Metropolitan Planning at the University of Utah. His focus is on active transportation and transportation demand management, and he is joining the University of Utah's sustainability office as the first Sustainability Graduate Assistant. Prior to beginning the masters program at UU he worked for the Tennessee Department of Transportation as a transportation program monitor.

Tell us about yourself?

It’s been quite a winding road for me to end up in the world of transportation planning. I went to Ole Miss for my undergrad in International Studies and Arabic because I thought I wanted to join the Peace Corps. Then I thought I wanted to be an English teacher, then a biologist. Eventually, I stumbled across a TDOT job posting in the Division of Multimodal Transportation Resources and thought to myself, “Multimodal? That means, like, bikes and buses and walking, right? I like riding my bike!” And that’s how I ended up working for TDOT, which eventually led me to the University of Utah.

I’m in my first semester of the Master of City and Metropolitan Planning program at the University of Utah. Outside of work and school, I enjoy cycling and playing Ultimate Frisbee. Since I’ve moved to Utah, I’m trying to get better at cycling up mountains because we don’t have those in Tennessee. I’m also...
