Automobile traffic congestion in urban areas comes with significant economic and social costs for everyone. According to the 2015 Urban Mobility Report, the total additional cost of congestion was $160 billion. As more people move to metropolitan areas, the problems only intensify. The latest NITC report offers a new approach to urban traffic signal control based on network consensus control theory which is computationally efficient, responsive to local congestion, and at the same time has the potential for congestion management at the network level.

Traffic signals represent a significant bottleneck. As...

Pedestrians crossing a street

The latest NITC report offers improved tools for pedestrian modeling.

Led by Kelly Clifton of Portland State University, researchers had previously created the the MoPeD pedestrian demand model as well as a pedestrian index of the environment (PIE) for forecasting pedestrian travel. The PIE index improved the sensitivity of walk trip models by incorporating contextual features of the built environment that affect walking behavior in the Portland, Oregon region. Read about Clifton's previous body of work on context-specific modeling.

Useful for academic researchers in transportation, Clifton's research provides a framework for incorporating pedestrian travel behavior forecasts into traditional four-step travel demand models.

Since the method was based on Portland, the next step was to adapt the tools for wider use. In this new report, Clifton and Jaime Orrego-Onate of...

Pedestrians cross near a light rail amid mixed-use development

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 data...

PSU students

For the second year in a row, we're opening up an exciting opportunity for undergraduate students interested in transportation: Spend a summer at Portland State University to learn more about the world of research in transportation through our Transportation Undergraduate Research Fellowship (TURF) program. This program is open to current undergraduate students from any university who are interested in learning more about transportation engineering or planning research. 

Hosted at PSU, selected students will be paired with a PSU faculty mentor (from either the College of Urban and Public Affairs or the Maseeh College of Engineering & Computer Science). The student will carry out research on a transportation project for ten weeks at 40 hours per week. TURF Fellows are provided a $7,500 stipend, but must find and fund their own lodging.

Decisions will be made by March 29, 2019. Contact us at asktrec@pdx.edu with any questions.

As transit agencies modernize their fare payment systems, opportunities to pay with cash diminish. This speeds boarding and lowers the cost of operations, while also creating new sources of ridership data. Arguably, service is improved for riders as well, where payment systems work across modes, and in some cases different transit providers, creating a more seamless and simplified experience. Still, about 15% of adults in the United States are without a bank account or credit card, and many rely on restrictive cell-phone data plans or don’t have access to a smartphone. These shares are even higher for public transit users. As transit fare technologies move further from cash, these digitally-excluded riders will find it more difficult to conveniently pay their transit fares.

In the latest project to be funded under the National Institute for Transportation and Communities (NITC)'s Pooled Fund grant program, researchers from...

The latest report from The National Institute for Transportation & Communities (NITC) offers help to planners seeking to incorporate emerging travel modes—including car sharing, bike sharing, ride hailing, and autonomous vehicles—into regional travel demand models. More specifically, it brings these new travel modes into the Regional Strategic Planning Model (RSPM) tool. As more people start taking advantage of new...

BIKE/PED COUNT SURVEY: CALL FOR INPUT

Researchers at Portland State University, University of Texas at Arlington, University of North Carolina at Chapel Hill and Toole Design Group are conducting a scan to identify locations where bicycle counts are taking place around North America, and hope to enlist your help! If you collect bike count data (or oversee counts) in your jurisdiction, please consider taking our quick survey to tell us a little bit about your count locations and data.

People talking and looking at materials in a workshop

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...
