While it’s generally accepted that dense, mixed-use development promotes active travel, researchers don’t have a consensus on exactly how, and to what degree, land use determines people’s travel patterns.

NITC’s latest report, Active Travel Behavior and Spatial-Temporal Land Use Mixing, provides some clarity on the topic.

NITC fellow Steven Gehrke focused his dissertation research on transportation-land use interaction, and sees land use mix as a multidimensional construct.

“We can refocus—away from increasing density—and think more about how we configure land uses,” Gehrke said.

According to Gehrke’s research, more density does not necessarily equal more walking. Rather, the complementarity, composition, and configuration of land use types is essential for cultivating walkability.

Gehrke, who graduates this spring with a Ph.D. in civil and environmental engineering from Portland State University, conducted three empirical studies under his dissertation grant. The first focused on improving measurements of land use mix, introducing a land use mix measurement of the composition and configuration of local land use types.

The second study looked at other smart growth principles, like employment concentration and pedestrian-...

NITC, through the Oregon Tech ITE Student Chapter, partnered with the ASCE/AGC Student Chapters to work with middle/high school students from the Klamath Basin in the design and construction of a pedestrian trail bridge near the Oregon Tech campus. See below for full story by Samantha Tipler, Klamath County School District.

Oregon Tech has linked up with Lost River Jr./Sr. High School to build bridges – both metaphorical and actual – between the two schools. Since March 17, the Oregon Tech Student Chapter of ASCE-AGC have been working with the Lost River STEM Club to design and build a bridge on the Oregon Tech trail up to the “O” near the solar power array on campus.OTBridge2017

“You wouldn’t think a couple seventh graders would be much help to make a big old bridge,” said Dustyn Verley, 13, “but it makes us pretty proud, I’d say.” Dystyn said that after helping pour concrete into wood forms on Friday, May 5. That was a no-school day for students and 13 of the 20 STEM Club members spent the day building the forms and digging holes for the concrete bridge.

“They’re gaining real life experience in seeing how bridges are built,” Lost River science teacher Mark Ferrara said, showing...

May was national bike month, sponsored by the League of American Bicyclists and celebrated in communities from coast to coast.

The NITC-supported ITE student chapter at the Oregon Institute of Technology helped to organize a "Bike, Walk or Run to Work" day on Friday, May 19.

Klamath County Public Health and the Blue Zones Project partnered to bring Bike to Work events to five locations around the town of Klamath Falls, Oregon, the home of Oregon Tech. 

Community members were invited to bike, walk, or run to work on May 19 and stop in at Gathering Grounds Roastery, Sky Lakes Medical Center, Mia & Pia's Pizzeria & Brewhouse, 173rd Fighter Wing, Kingsley Field, or Klamath Community College for free breakfast and refreshments.

There was also a raffle, with prize drawings at 5:.30 p.m. at Gaucho Collective.

The more participants actively commuted to work throughout the week, the more chances they had to win prizes.

Oregon Tech's ITE Student Chapter member staffed four breakfast stations across the Klamath Basin to encourage community members to consider healthier forms of transportation for their commutes.

By bringing residents, worksites, schools, restaurants, grocery stores, and government together, Blue Zones and Oregon Tech hope to inspire a community movement to improve quality of life for everyone. Bike to Work day was an indicator of that growing...

As social media comes to permeate every aspect of modern life, public transit is no exception.

Transit agencies are increasingly making social media an integral part of their day-to-day management, using it to connect with riders about system alerts, live transit arrival information, service disruptions and customer feedback.

However, there is very little evidence to show how effective these efforts really are in achieving agency goals.

Measuring the Impacts of Social Media on Advancing Public Transit, a NITC project led by Jenny Liu of Portland State University, seeks to provide a better understanding of how transit agencies use social media and to develop some performance measures to assess the impacts of social media on promoting public transit.

This project aims to measure how social media actually impacts agency goals like increasing recruitment and retention of transit riders; increasing resources and customer satisfaction; addressing system performance efficiency; and improving employee productivity and morale.

A survey of 27 public transportation providers across the country found that although 94% of those surveyed agencies used some form of social media, only 28% had a social media plan or strategy prior to implementation.

Liu’s research explores the types of performance measures that could...

While bike-sharing systems become increasingly common in American cities, questions about the equity of such systems are making their way to the forefront of the conversation.

Bike share can provide a cheap and healthy means of transportation, but many systems are not serving the lower-income and minority populations who, arguably, could benefit most from having the additional travel option.

A survey of 56 bike share system operators in the United States offers an overview of how these equity concerns are being addressed.

The survey is part of a larger research effort, Evaluating Efforts to Improve the Equity of Bike Share Systems. To gain an understanding of the challenges and opportunities involved in providing more equitable bike share, TREC and NITC teamed up with the Better Bike Share Partnership: a collaboration between PeopleForBikes, the National Association of City Transportation Officials (NACTO), the City of Philadelphia, the Bicycle Coalition of Greater Philadelphia, and other local partners.

Nathan McNeil, a Portland State University research associate, is leading the research team in evaluating efforts to improve bike share equity with co-investigators John MacArthur and Jennifer Dill.

Everyday cycling for transportation can have positive, population-level health impacts.

Significant deterrents to cycling remain, however, particularly for women and minorities.

Narratives of Marginalized Cyclists, a NITC project conducted by Amy Lubitow of Portland State University, explores the experiences of women and minorities biking in Portland, Oregon.

Lubitow interviewed 28 Portlanders who self-identified as a woman or as a racial/ethnic minority (or both), and based on the insights gained from their stories, came up with a set of recommended interventions for planners to mitigate the barriers they experience.

"Institutionalized racism and sexism is hard to fix. These are complicated issues that involve multiple levels of interventions, but at a basic sort of smaller scale, there are things we can do," Lubitow said.

She chose participants who own a bike and ride it at least once a month, but not more than once a week. The primary aim of the project was to collect rich, narrative data regarding obstacles to routine or utilitarian cycling for women and minorities who already see biking as a viable form of transportation, but who make relatively few bike trips.

The interviews...

We drive on infrastructure from the last century, never knowing when its shaking in the wind might herald a collapse, while in our hands are devices that can communicate with satellites, capture high-definition video and sense the motion of a fly. To C.J. Riley, it seemed like the one should be able to help with the other.

Riley, an associate professor of civil engineering at the Oregon Institute of Technology, is working on NITC research aimed at using low-cost, ubiquitous technology—like third-generation iPods—to evaluate the soundness of bridges and other transportation structures.

The goal of his just-published NITC education project, Dynamic Evaluation of Transportation Structures with iPod-Based Data Acquisition, was to expand Oregon Tech’s research lab while simultaneously figuring out two things: how can widely available technology be leveraged to assess structural integrity, and what is the best way to teach students this process?

To address both questions, Riley established the Structural Health and Kinetic Evaluation (SHAKE) Laboratory at Oregon Tech. While exploring options for structural assessment, Riley put some new lab tools in the hands of his graduate students: twelve third-generation iPod touch mobile devices with on-board accelerometers, Texas Instruments SensorTags, virtual visual sensors, and a...

Gentrification is a common, and deeply controversial, outcome of urban development.

It's usually the same story: investments in new infrastructure draw the affluent, causing market forces to displace lower-income residents. Neighborhoods become renovated, and the people who once defined the neighborhood can no longer afford to live there.

NITC researcher Gerardo Sandoval shows in his latest project that it doesn’t have to be that way.

With the right level of community input, transit-oriented development has the potential to bring needed services to low-income residents while revitalizing their neighborhoods.

Sandoval, an associate professor of planning, public policy and management at the University of Oregon, demonstrates in numerous case studies how transit-oriented development, or TOD, can modernize and improve neighborhoods without driving residents out. His research focuses on Latino immigrant communities in California.

Through the examination of these case studies, Sandoval hopes to provide a model for planners and agencies to create equitable TODs.

Beginning in 2012 with a NITC project called Latino Immigrant Communities and Equity in Transit Oriented Development, Sandoval first conducted qualitative studies of TODs in two California...

A new NITC report examines factors that predict whether a driver will comply with Oregon laws aimed at keeping pedestrians safe.

Miguel Figliozzi of Portland State University, director of the Transportation, Technology & People (TTP) research lab, has done extensive work in Portland, Oregon modeling and analyzing the complex interactions between cars, transit, traffic signal technologies and human roadway users.

The research seeks to provide a better understanding of the tradeoffs between traffic mobility, transit performance and pedestrian access.

The first phase of Figliozzi’s research focused on how two advanced traffic control technologies work together. In this second phase, he zeroes in on pedestrian safety.

The report examines traffic and trajectory factors that explain whether a driver complies with Oregon law, which has strong pedestrian protections. In Oregon, drivers must stop for pedestrians as soon as they move onto the roadway in a crosswalk with the intent to proceed.

Oregon state law determines that there is a crosswalk at every intersection with or without a marked crosswalk. The state also requires that a driver, before crossing a crosswalk, stop and remain stopped for pedestrians until the pedestrians...
