Addressing Bicycle-Vehicle Conflicts with Alternate Signal Control Strategies -and-
Improving Bicycle Crash Prediction for Urban Road Segments
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 intensive training event for transportation professionals.... Read more
Stephanie Nappa, University of Oregon
We're shining our student spotlight this month on Stephanie Nappa, president of the University of Oregon student group LiveMove. On May 24, LiveMove will host a speaker series event with Oboi Reed, the Executive Director of Equiticity, to discuss equity in biking.

I’m a former engineer and chemist who began studying planning once I learned there was a career that would allow me to talk endlessly about transportation systems without simply receiving polite nods. Currently, I’m about to finish my Master of Community and Regional Planning degree from the University of Oregon, where I’ve focused my studies on active transportation. This past summer I had the opportunity to take a study abroad course on bicycle transportation in Denmark, Sweden, and the Netherlands, which was an incredible...Read more
Every day transit riders ask the same question: when’s the next one coming? To answer this question, transit agencies are transitioning to providing real-time transit information through smartphones or displayed at transit stops.
Real-time transit information improves the reliability and efficiency of passenger travel, through:
- shorter perceived and actual wait times,
- an increased feeling of safety,
- increased ridership, and
- a lower learning curve for new riders, since they don't have to know the route maps or...
noun liv·abil·i·ty \ ˌli-və-ˈbi-lə-tē \
"Livability" is a broadly used term encompassing all the factors that add up to a community’s quality of life. It’s a key goal in many land use and transportation plans, but it's not always clear how to reach that goal. What makes people feel that their neighborhoods are livable?
Researchers Rebecca Lewis and Robert Parker of the University of Oregon surveyed over three thousand...Read more
The National Institute for Transportation and Communities (NITC) is proud to announce our two Spring 2018 Dissertation Fellows. Hear from the fellows about their projects below, or learn how to apply for funding through the NITC Dissertation Fellowship Grant here. Proposals for Summer 2018 Dissertation Fellowships are due June 1, 2018.
Vivian Miller, University of Texas at Arlington
In November 2018, Vivian Miller published Investigating Barriers to Family Visitation of Nursing Home Residents: A Systematic Review, a paper based on her NITC-funded dissertation, in the Journal of Gerontological Social Work.
Vivian Miller is a third-year doctoral candidate in the School of Social Work at the University of Texas at Arlington. Her primary research interests are in...Read more
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.

The most expensive and critical links in our transportation network are its bridges. Historical and contemporary bridge failures have highlighted our reliance on these structures. While the nation’s bridge management system is robust and well administered, the tools needed to evaluate individual bridges to determine their condition—whether for asset management or in response to a significant loading event such as the imminent Cascadia Subduction Zone earthquake in the Pacific Northwest— are currently highly specialized.
NITC researcher C.J. Riley, a civil engineering professor at the Oregon Institute of Technology, has developed a cost-effective, accurate, and easily deployed evaluation tool using widely available mobile technology (specifically iPods) to measure the dynamic structural response of a bridge subjected to harmonic forcing....

Vehicle operating dynamics data have a fundamental impact on the design of roadways, but collecting this type of data is not part of your typical college curriculum.
Instead, engineering students are handed a textbook, leaving them without a firsthand experience of how accelerations and decelerations “feel” to the driver, the ultimate consumer of their designs.
Seeking to change this norm, Roger Lindgren and C.J. Riley, civil engineering professors at the Oregon Institute of Technology, undertook a NITC education project to incorporate more real-world data collection and...Read more
A newly published NITC education project offers tools for teaching collaborative regional planning in communities close to national parks and other natural attractions.
Referred to as Gateway and Natural Amenity Region (GNAR) communities, these unique places have their own set of challenges and opportunities. They are often located near small towns or rural areas with limited transportation networks, but due to the periodic influx of visitors, can experience “big city problems” like congestion and sprawl.
