Sirisha Kothuri, a Portland State University research associate, has recently completed two distinct studies taking different approaches to advancing bicycle safety. Kothuri will lead a Sept. 13 workshop on Bicycle/Pedestrian Focused Signal Timing Strategies along with Peter Koonce, the division manager of Signals & Street Lighting for the City of Portland. The half-day workshop will be part of Transportation and Communities 2018, a two-day...

If more drivers switched seats to a bicycle, there would be immediate and tangible benefits on the road. Widespread adoption of bike commuting could improve public health through increased physical activity and reduced carbon emissions, as well as ease the burden on congested roads. However different lifestyle demands, physical ableness, and varied topography create an unequal playing field that prevents many from replacing their car trips.

Electric bicycles (e-bikes) are a relatively new mode of transportation that could bridge this gap. If substituted for car use, e-bikes could substantially improve efficiency in the transportation system while creating a more inclusive biking culture for people of all ages and abilities.

A newly published NITC study by John MacArthur of...

The third and final phase of our bike share equity research project has been published, with new findings from a survey of bike share users.

Riders targeted for equity-focused outreach efforts—lower-income individuals and people of color—were most likely to cite cost savings or discounted membership as reasons why they joined, while higher-income and white users were more likely to cite the convenience of using bike share. Lower-income riders were also more likely to have heard about...

The National Institute for Transportation and Communities (NITC) program has released its 2018 general research request for proposals. Faculty at NITC's partner universities* are invited to submit abstracts by April 2, 2018.


Through funding provided by the U.S. DOT, we will award at least $1 million under our general research grant in 2018 for 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

Research projects must focus on transportation, with additional consideration given to projects that emphasize equity and diversity in their research and partnerships. We’re seeking projects that demonstrate a strong potential to move transportation research into practice, shape national and international conversations, and respond to the needs of practitioners and policymakers. 

Priority is given to projects that are collaborative, multidisciplinary, multi-campus, and support the development of untenured-tenure-track transportation faculty. 

Key Dates

Learn more about this curriculum and how you can apply it at your school by viewing the one-page Executive Summary and the full Final Report on the Project Overview page.

A NITC education grant funded a new course for planners, engineers, scientists and students to help improve their data processing workflow.

Liming Wang, an assistant professor in the Toulan School of Urban Studies & Planning at Portland State University, is on a mission to simplify data processing. A NITC education grant supported his efforts to develop a new course: Introduction to Data Science (Aug 6 - 10, 2018). The course is designed to help students and professionals to improve their workflow for data-intensive research. The course covers how to collect data, clean them up, visualize, explore, model and eventually compile the data with findings in a report.

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

Small Starts grants assist researchers who are interested in transportation but have not yet had an opportunity to undertake a small project—$15,000 in funding or less—that supports NITC's theme of safe, healthy and sustainable transportation choices to foster livable communities.

The latest projects selected by NITC's executive committee support that theme in exploring livable streets, multimodal safety and transportation efficiency.

The six newly funded projects are:

  • Is There a "Buy Local" Case for Lower Travel Speeds? Testing Differences in Driver Recognition of Local Versus National Retail at Different Travel Speeds—Jonathan Bean and Arlie Adkins, University of Arizona (Full Proposal)
  • How Will Autonomous Vehicles Change Local Government Budgeting and Finance? A Case Study of Solid Waste, Drop-off/Pick-up Zones, and Parking—Benjamin Clark, University of Oregon (...

Project Overview: Data and Methodological Issues in Assessing Multimodal Transportation Impacts for Urban Development
Learn more about this research by viewing the two-page Project Brief, related presentations, and the full Final Report on the Project Overview page.

As cities aim to promote sustainable, multimodal growth, sometimes the way we go about development review processes can create barriers to achieving the results we want. Some of the methods we have inherited, while still useful, have distinct limitations.

NITC dissertation fellow Kristina Currans took on this challenge in her doctoral research project, Data and Methodological Issues in Assessing Multimodal Transportation Impacts for Urban Development.

The guidelines for evaluating transportation impacts of new development were originally published  in 1976 by the Institute of Transportation Engineers (ITE). Decades later, we’re still using essentially the same processes all across the U.S. and Canada, and these methods—which harbor a lack of...

Normally we assume that travel is a means to an end, but the latest NITC report examines other benefits of travel—aspects that aren’t about reaching a destination.

One such benefit is travel-based multitasking. A good example of this is using time on a commuter train to listen to music, relax or get some work done. The simple enjoyment of a walk in the fresh air relates to another benefit, known as subjective well-being, in which the act of travel itself makes a person feel better. These intrinsic benefits can impact travel behavior and mode choice, but our current models don’t have any way to reflect this.

NITC fellow Patrick Singleton investigated the policy and planning implications of this in his dissertation, Exploring The Positive Utility Of Travel And Mode Choice.

"The way we analyze travel behavior assumes people want to get from A to B as quickly as possible. We don’t include the...
