The final report on this research is available now: Design for an Aging Population
Published in April 2017, this study sought to increase understanding of the obstacles faced by people with impairments in vision, hearing and/or mobility, which are common issues for older people, and generate physical product solutions.
The research shows that aging riders face conceptual, physical and social barriers that impact their willingness to use buses. Using the bus was seen as inconvenient, time consuming, physically draining and potentially frustrating. Priority seating areas designated for older and disabled users fill quickly. People with mobility challenges may use bulky walkers and require the availability of grab bars, and users of wheeled mobility devices need different device security. Several situations noted in the study show that physically challenged riders are subject to awkward, uncomfortable social dynamics more than other bus users. Innovation in easy access seats and secure WhMD stations at the front of the bus are critical for older users, as it makes riding the bus less draining and more safe.

Portland State University has secured a five-year grant from the U.S. Department of Transportation for transportation research, education and outreach. Portland State’s Transportation Research and Education Center, TREC, will administer the grant, which is expected to total $15.6 million.
The grant names TREC's National Institute for Transportation and Communities program, or NITC, as one of five national university transportation centers. TREC will expand the NITC program and add new partners University of Arizona and University of Texas at Arlington. Existing partners University of Oregon, Oregon Institute of Technology and University of Utah remain partners in the Portland State-led program.
The NITC program will focus on four research areas: increasing access to opportunities; improving multi-modal planning and shared use of infrastructure; advancing innovation and smart cities; and developing data, models and tools. Among the 11 projects funded in the first year of the grant are:
- A smart platform for connected vehicle infrastructure and signal control;
- A multidisciplinary look at how the concept of walkability has left out disadvantaged neighborhoods and how to address those gaps;
- Two innovative efforts to help transit connect people with jobs and opportunities;
- An examination of the economic and business effects of converting infrastructure for nonmotorized...
TREC research takes center stage in Washington, D.C. at this week’s University Transportation Center Spotlight Conference, sponsored by the U.S. Department of Transportation. The conference spotlight topic changes each year. This, the 10th annual conference, focuses on pedestrian and bicycle safety.
Conference chair Jennifer Dill, director of TREC and its NITC program, opens the program Thursday by defining the safety threats for people walking and bicycling in our communities. She will then task attendees with addressing the problem.
“I’m pleased to have the leading researchers on these issues together,” Dill said. “This conference provides opportunities for collaboration and synergies that advance the state of research.”
TREC’s John MacArthur and Christopher Monsere moderate a breakout session on bicycle infrastructure that includes a presentation from Monsere and NITC researcher David Hurwitz on right-hook crashes. Portland State researchers also present topics including pedestrian crossing enhancements, the psychology of roadway interactions,and developing an online tool for pedestrian and bicycle...
Vanessa Garrison, co-founder of national walking movement GirlTrek, gave the Ann Niles Active Transportation Lecture October 19 at Portland State University. Her simple, powerful message has mobilized more than 75,000 black women and girls since 2011 to start changing their lives and their communities for the better.
“Change starts with one woman,” she said. That is GirlTrek’s change theory: start with one woman, and there is a ripple effect.
Every time one woman is inspired by GirlTrek to commit to a daily habit of walking, so the theory goes, she can begin to motivate her friends, family or neighbors to walk with her and the movement gains another focal point around which to build momentum.
It's about health, but so much more.
In improving her own health, each GirlTrek walker gains the strength to effect other positive changes in her world.
With a group of women walking together every day, the neighborhood becomes safer. Then, depending on the needs of the community, more change begins to evolve. Are there safe sidewalks? Does traffic speed down the streets of the neighborhood? Should there be more destinations to walk to? What forms of social injustice can be addressed at the local level? These are questions that GirlTrek staff members love to help trekkers answer.
“Whatever it is that a women needs, to go back into her community and create change, we help bring her there,” Garrison said...Read more
A new NITC report introduces an important tool for safety analysis: a naturalistic method of data collection that can be used to improve the cycling experience.
Before now, most naturalistic studies (studies where data are collected in a natural setting, rather than a controlled setting) in bicycle safety research have been captured by stationary cameras and haven't followed cyclists along a route.
Researchers in this study used first-person video and sensor data to measure cyclists' reactions to specific situations.
Safety research in general has advanced significantly through naturalistic driving studies, which gather data from real drivers to illuminate the causes of traffic incidents both major and minor. For motorized vehicles, the U.S. Department of Transportation has been developing portable, vehicle-based data collection technologies since the early 1990s.
Their report, Utilizing Ego-centric Video to Conduct Naturalistic Bicycling Studies, offers a successful method for integrating video and sensor data to record...Read more
The 2016 Transportation and Communities Summit set off on a different path from previous summits and brought new energy into discussion of the future of transportation. Around 285 people attended the summit, held Sept. 8-9 at Portland State University, an increase from last year.
First-time attendees made up a sizable percentage of conference-goers. Of those responding to a post-summit survey, more than 40 percent had never attended a summit before.
Responding to feedback from previous attendees, TREC organizers added a day of workshops before the main summit day. The workshops allowed attendees to dive deeper into specific transportation topics and interact with moderators and other participants to address real-world problems.
The lively poster session also served its goal of fostering conversations between practitioners, academics and students. Attendees consistently rate networking as one of the most valuable aspects of the summit, and the poster session—with more than twice the posters of previous summits—helped make those interactions more productive.
Topical breakout sessions form the backbone of the summit, showcasing the best thinking around issues from researchers and practitioners. Previous summits offered two breakout slots with four sessions each, meaning a single attendee could only attend a quarter of the sessions offered. The 2016 summit, by contrast, offered three breakout slots with...Read more
The success of TREC’s first summer program for high-school girls shows promise for the future transportation workforce. The National Summer Transportation Institute, held July 11-22, gave 22 girls classroom and hands-on instruction with transportation experts in various fields and sectors.
While high school girls and boys enroll in higher science and math classes at the same rate, fewer girls persist in the STEM fields of science, technology, engineering and math. That carries into the workforce, where women still hold a small percentage of transportation-related jobs. Fewer than a quarter of transportation supervisors, and under 14 percent of civil engineers are women, according to the U.S. Department of Labor.
A goal of the summer institute was involvement of underrepresented groups, and more than half the students identified themselves as girls of color. The institute sought to inspire...
Vanessa Garrison didn’t set out to build a health movement. Growing up in Seattle’s Central District, a historically black neighborhood, Garrison just wanted her household and her community to be healthy.
“It was a challenge for me to develop solutions that work for the women I love,” Garrison said.
Those solutions, however, did set off a movement: GirlTrek, a community-based walking movement that has reached 250,000 black women and girls across the country. Garrison co-founded GirlTrek and serves as its chief operating officer.
“Seattle is one of the most active cities in the country, but my household was completely inactive,” Garrison said. “All the women in my family were really experiencing health challenges due to chronic disease.”
Those problems ran deeper than simply inactivity. Obesity and inactivity often have roots in concerns about safety and other community issues built on historical trauma and systemic racism. A fitness-only approach, Garrison reasoned, would fail to overcome these powerful forces.
With friend Morgan Dixon, who would become her GirlTrek co-...
Oliver Smith, a former NITC dissertation fellow with a Ph.D. in Urban Studies from Portland State University, published research findings last month in the Journal of Transport and Health.
The study includes evidence that walking and biking have a significant positive effect on wellbeing, and suggests that bicycling to work may benefit mental as well as physical health.

Smith created a measure of how individuals feel about their commute to work: CWB, or “commute well-being.” To quantify a person’s CWB, he used a composite measure based on seven questions that measure both emotional and cognitive responses to the commute.
He surveyed commuters traveling to work in central Portland...Read more
