Researchers Aaron Golub, John MacArthur and Sangwan Lee of Portland State University, Anne Brown of the University of Oregon, and Candace Brakewood and Abubakr Ziedan of the University of Tennessee, Knoxville have published a new journal article in the September 2022 volume of Transportation Research: Interdisciplinary Perspectives

Rapidly-evolving payment technologies have motivated public transit agencies in the United States to adopt new fare payment systems, including mobile ticketing applications. The article, "Equity and exclusion issues in cashless fare payment systems for public transportation," explores the challenges facing transit riders in the U.S. who lack access to bank accounts or smartphones, and potential solutions to ensure that a transition to cashless transit fares does not exclude riders. Learn more about the project and read an open-access version of the final report.

The study asks: who is most at risk of being excluded by the transition to new fare payment systems and how would riders pay transit fares if cash payment options were reduced or eliminated? Researchers answer these questions using intercept surveys of 2,303 transit riders in Portland-Gresham, OR, Eugene, OR, and Denver, CO.

The article's authors explore existing research on emerging fare payment systems, as well as research on disparities in access to the various pieces of the new payment ecosystem, including credit and banking, Internet and smartphones. They then present qualitative and quantitative analyses used to investigate this topic, and conclude with a discussion of results and implications for policy and planning. The paper is based on a pooled-fund study supported by the National Institute for Transportation and Communities (NITC). Read more about the original study: Applying an Equity Lens to Automated Payment Solutions for Public Transportation

In order to make sure bicyclists' needs are considered when improving a transportation system, planners and engineers need to know how many people are biking, and where. 

Traditional bicycle counters can provide data for limited sections of the bike network; often these counters are installed at important locations like trails or bridges. While limited in location, they count everyone who bikes by. Meanwhile, GPS & mobile data cover the entire transportation network, but that data only represents those travelers who are using smartphones or GPS. Combining the traditional location-based data sources with this new, crowdsourced data could offer better accuracy than any could provide alone. 

"Knowing how many people are bicycling on a street is really important for a number of reasons. As just a few examples, bicycle volumes give you a way to understand safety data and determine crash rates. They provide insight into where and how bicycle trips are taking place, which can help plan for new or improved facilities," said Nathan McNeil of Portland State University.

Supported by a pooled fund grant administered by the National Institute for Transportation and Communities (NITC), Dr. Sirisha Kothuri of Portland State University led a research project aimed at fusing traditional and emerging data sources together, to derive bicycle volumes for an entire transportation network. The team developed three models and tested them in six cities: Dallas, Texas; Portland, Bend and Eugene, Oregon; Boulder, Colorado; and Charlotte, North Carolina. Learn more about the project in this research highlight video.

Related research: This is one of many NITC studies advancing the collection, methodology, and analysis of multimodal data that supports professionals and researchers in understanding and predicting human travel behavior in order to optimize those systems for both the providers and users. Learn about more NITC research in the area of multimodal data and modeling.

DEVELOPING THREE BIKE COUNT MODELS

With Kothuri as principal investigator, the research team included Joe Broach and Nathan McNeil of PSU; Kate Hyun, Stephen Mattingly and Md. Mintu Miah of the University of Texas at Arlington; Krista Nordback of the University of North Carolina's Highway Safety Research Center, and Frank Proulx of Frank Proulx Consulting LLC. 

First, the team conducted a literature review while cataloging and evaluating the available third-party data sources and existing applications. They chose the six study sites to represent a variety of urban and suburban contexts, with plenty of geographical diversity, and existing bike data available. Of the six, Boulder, Charlotte and Dallas constituted basic sites, where one year of data (2019) was used for modeling. Portland, Bend, and Eugene in Oregon were considered enhanced sites, where three years of data (2017–2019) were used for model estimation. 

The team chose three relatively new data sources: Strava, Streetlight Data, and GPS data from bike share systems in the case study cities. After collecting demographic, network, bike count and emerging data from the new sources for each of the cities, they developed three sets of models: 

  1. One with pooled data from all six cities,
  2. another with just the pooled data from the three Oregon cities,
  3. and finally a set of city-specific models. 

The researchers then applied the results to each of the six study sites. The city-specific models generally performed the best, showing the most accuracy in predicting bicycle volumes. The scripts used to run the models will soon be published to GitHub, and a link will be posted on the project page for anyone interested in accessing the models.

In general, the various data sources appeared to be complementary to one another; that is, adding any two data sources together tended to outperform each data source on its own. Adding even more data should continue to refine accuracy. The findings from this study indicate that rather than replacing conventional bike data sources and count programs, big data sources like Strava and StreetLight actually make the old “small” data even more important.

"We will need more ground-truth counts for low-volume sites to capture the variety of locations, and that will make more robust models," said Kate Hyun of UTA.

BETTER MODELS PROVIDE MORE ACCURATE PERFORMANCE MEASURES FOR TRANSPORTATION AGENCIES

Josh Roll, Research Analyst & Data Scientist at the Oregon Department of Transportation, served as the chair for the project’s technical advisory committee. He believes the outcome of this research could help transportation agencies get a better handle on how many people are biking in their communities. 

“At ODOT we just adopted "Bicycle Miles Traveled" as a new key performance measure, and we need a way to measure it, so this project very much helps to fill the gap on how we're going to do that. This research used cutting-edge data fusion techniques that could lay the groundwork for how transportation agencies like ODOT monitor bicycle activity across the system,” Roll said.

For transportation agencies wishing to support active travel to meet various sustainability, public health, and climate-related goals, quickly having accurate data for the entire network would be a giant leap in the right direction.

Robust, organized, and accessible count programs will be essential to get the most out of emerging data sources. The more good, vetted data are available, the better models based on emerging sources will perform, so professionals managing bicycle count programs should focus on making data uniform and widely usable.

"In order to integrate all of these disparate data sources – automated and manual counts, opt-in apps like Strava, passively collected background data like Streetlight, and GPS-enabled bike sharing systems — into one coherent system, data professionals should organize their data to best take advantage of these new data fusion possibilities. This means making sure nonmotorized data are accurate, consistent, and useful," said Sirisha Kothuri, lead researcher on the project.

Tell us about yourself?

Currently I'm a 5th year urban studies Phd candidate. Originally from Chicago, I also call Portland and Hong Kong home. Off campus, you can find me on the rugby pitch with the Portland Lumberjacks RFC or foraging Oregon’s forests for mushrooms.

What (or who) has influenced your career path in transportation?

Growing up in Chicago and working as a bike messenger provided a massive influence on my career in transportation and urban planning. These experiences really pushed me to go into transportation planning. Working and researching at the Chinese University of Hong Kong solidified my decision to pursue a career in academia.

You're currently supporting a project on marginalized populations' access to transit, and you recently successfully defended your dissertation proposal on "Expanding transmobilities: An art-informed methodology for gender-diverse travel behavior." Tell us about those projects?

Absolutely! My dissertation works focuses on understanding how genderdiverse individuals' gender identity influences their travel behavior and travel decisions. I will use collage and mental maps as my methodology to delicately capture these data. I believe this work will support mobility justice research and the greater social justice movement.

Learn more about the active NITC-funded project "Marginalized Populations’ Access to Transit: Journeys from Home and Work to Transit", led by Marisa Zapata of PSU.

After graduation, what future work do you envision doing in transportation?

Ideally after graduation, I plan to secure a tenure track position at a research oriented university abroad, either in Europe or East Asia. Preferably, I would love to continue my dissertation research and add more knowledge to the mobility justice field.

Researchers at Portland State University and Oregon State University have updated the Oregon Department of Transportation (ODOT) Safety Investigation Manual, materials and training resources to assist ODOT traffic investigators with highway safety project investigation, analysis, evaluation, and documentation.

David Hurwitz of OSU worked with Chris Monsere, Sirisha Kothuri and Jason Anderson of PSU to update the manual. The team revised and expanded worksheets used in the safety analysis process and prepared training materials in the form of videos, slide decks, and case study examples to help train ODOT employees and employees from transportation agencies around the state on current best practices.

A decade ago, the first edition of the Safety Investigation Manual was also developed by PSU (Chris Monsere) in collaboration with OSU (Karen Dixon). ODOT continues to look to the leading experts in transportation safety engineering at Oregon's public universities. PSU and OSU have a long history of working together on transportation projects, including addressing safety concerns for senior drivers and pedestrians, assessing bicycle detection and road user understanding of bicycle signal faces on traffic signals, improving safety and efficiency of protected/permitted right turns, and pedestrian safety at signalized intersections operating the flashing yellow arrow.

In addition to providing a comprehensive procedure for safety investigation at both intersection and highway segments, the manual also includes checklists and analysis procedures suitable for a variety of field and office safety investigations and assessments. A consistent approach to safety investigations is critical to ODOT’s Transportation Safety Action Plan (TSAP), which aims to eliminate fatal and serious injuries entirely by 2035.

In 2020, the COVID-19 pandemic drastically impacted travel for in-person shopping, commute trips, global supply chains, and food business operations. E-grocery pickup and delivery services saw unprecedented expansions in response. The adoption and use of these e-grocery services have implications for equity and mobility. A PSU masters thesis offers insights: "Adoption and Use of E-Grocery Shopping in the Context of the COVID-19 Pandemic: Implications for Transport Systems and Beyond" by Gabriella Abou-Zeid, a 2021 graduate of Portland State University with a masters in civil engineering.

"While the future adoption and use of e-grocery services is uncertain as the COVID-19 pandemic evolves, our analysis revealed a clear impact of the pandemic on e-grocery shopping behaviors, which has impacts for transportation network demand, safety, and equity," Abou-Zeid said.

Enhancing our understanding of the drivers of (and barriers to) online grocery shopping and its potential "stickiness"—or the extent to which e-grocery use will continue at the same or higher frequencies after the pandemic—is a prerequisite for unpacking current and future consequences of this ecommerce sector on people and transportation networks. The two goals of this work are:

  1. To explore the drivers of adoption and use of e-grocery services in the context of the COVID-19 pandemic, and
  2. To estimate "stickiness" of online grocery ordering behaviors – or the extent to which e-grocery use will continue at the same or higher frequencies after the pandemic.

Survey data (N=2,266) capturing household and individual information on demographics, attitudes, and behaviors were all employed in carrying out these goals. The culmination of results show attitudes and COVID-19 related variables are strong drivers of e-grocery adoption, use, and stickiness. COVID-19 related characteristics—including individual and household experiences related to employment, income, remote work, diagnosis, food insecurity, and changes in food shopping behaviors—were found to be significant across the suite of estimated models, demonstrating the sheer impact of the pandemic on household provisioning behaviors. Results from the "stickiness" analysis suggests households that are multimodal, below retirement age, and located in places with high e-grocery service availability are more likely to hold or increase their already elevated e-grocery usage. Households who have at least one member particularly vulnerable to COVID-19 or who reduced their in-store shopping frequency during the pandemic are also more likely to have e-grocery shopping "stick". Drivers of e-grocery delivery adoption varied among household income levels.

“It’s Complicated”: Exploring the Relationship Status of In-store and Online Grocery Shopping During the COVID-19 Pandemic (View PDF)

One theme resurfaced consistently throughout the analysis: the importance of attitudes in predicting behavior. “Attitudinal variables showed significance across all models examining e-grocery adoption, use, and ‘stickiness’. As just one example, households who knew others who shopped for groceries online, and who thought shopping online was easy, were more likely to demonstrate e-grocery adoption and use, and were more likely to continue e-grocery shopping behaviors after the pandemic. Households who preferred to use cash when grocery shopping were less likely to continue use of e-grocery shopping after the pandemic, which points to a potential barrier for un- or underbanked households in being able to easily use these services”, Abou-Zeid noted.  

The work concludes with a synthesis of findings, highlighting key drivers of and barriers to online grocery shopping, the impacts of the COVID-19 pandemic on e-grocery, and implications for transportation systems and practice. This discussion includes recommendations for policy and future work.

The data collection effort, led by Dr. Kelly Clifton, supporting this research was funded by the National Science Foundation (NSF) and the National Institute for Transportation and Communities (NITC). Abou-Zeid would also like to acknowledge the Federal Highway Administration’s (FHWA) Dwight D. Eisenhower Transportation Fellowship Program (DDETFP) and the National Institute for Transportation and Communities (NITC) for the financial and professional support provided while developing her thesis.

Abou-Zeid presented this research in a poster session (download the PDF) at the 2022 annual meeting of the Transportation Research Board (TRB). She also presented her work at the two previous TRB conferences in 2020 and in 2021, where she was awarded her first and second Eisenhower Fellowship.

Abou-Zeid now works as a Transportation Data Specialist at ICF, supporting local, state, and federal clients in areas of transportation demand management (TDM), transportation systems management and operations (TSMO), public transportation investments, transportation and land use intersections (especially related to parking), and sustainable mobility. She currently resides in Tucson, AZ, where her transportation research journey began while researching walkability.

We produce impactful research and tools for transportation decision makers, expand the diversity and capacity of the workforce, and engage students and professionals through education and participation in research.

In 2022, a PSU Master of Urban and Regional Planning (MURP) team made headlines with their strategies to improve safety for houseless pedestrians. Cities across the U.S. are facing alarming increases in traffic fatalities, especially among the number of pedestrians who are struck and killed by drivers. In 2021, 70 percent of all pedestrian fatalities in Portland were of people experiencing houselessness. The MURP team Street Perspective, made up of Peter Domine, Nick Meusch, Asif Haque, Angie Martínez, Sean Doyle, and Meisha Whyte, investigated how to reduce the risk of being hit and killed specifically for unhoused people. 

As the Portland Bureau of Transportation (PBOT) is updating the city's Vision Zero Plan, the team provided PBOT with recommendations to reduce the risk of pedestrian fatalities among the city's vulnerable houseless communities.

Watch the recorded Friday Transportation Seminar from June 3, 2022, or view the final report: "Safety Interventions for Houseless Pedestrians" (PDF)

"A disproportionate number of unhoused pedestrians are being killed in car crashes across America — and protecting this uniquely vulnerable group will require a set of strategies that both include and exceed even the conventional street safety playbook... To understand how Portland could do a better job of protecting houseless people from traffic violence — and perhaps chart a model for analysis other communities could follow — the Portland State researchers conducted dozens of interviews, in addition to performing spatial analysis on fatal crash sites that sat within 250 feet of both 1) a reported campsite for unhoused people, and 2) a segment of the city’s High Crash Network, where most of Portland’s vehicle collisions occur," Kea Wilson of Streetsblog USA wrote about the team's work.

BikePortland covered the project as well, focusing on Portland and the city's history of approaches to dealing with houseless individuals and communities. Journalist Taylor Griggs described the team's strategies to reduce crashes near homeless camps as "promising."

The PSU Master of Urban and Regional Planning (MURP) program is known for its workshop projects. For the last two quarters of the program, students work on community-based, client-focused projects. This provides students with the opportunity to work in teams on real-world problems for community clients. Learn more about the MURP program.

Active transportation investments offer many types of benefits related to safety, reduced greenhouse gas emissions, physical activity and the economy. Metro, Oregon’s regional government for the Portland metropolitan area, wants to better understand the role of these investments in building stronger communities in their region, and in implementing the Metro 2040 Growth Concept.

Led by Portland State University in partnership with Metro, the Active Transportation Return on Investment (ATROI) study looked at twelve projects constructed in the greater Portland region between 2001 and 2016. These twelve 2040 Catalyst Projects were evaluated to determine if active transportation investments had significant effects on the local economy. 2040 Catalyst Projects retrofit busy commercial streets with pedestrian-friendly treatments to catalyze economic development within 2040 Centers, Main Streets, or Station Communities. 

Redesigned streets can improve economic conditions by creating attractive and walkable business districts, providing access to various destinations, local businesses, and jobs. Nearly all the projects focus primarily on pedestrian improvements, such as improved sidewalks (new, widened, etc.), safer crossings (signals, rectangular rapid flash beacons, curb extensions, crosswalks, signage, ramps, etc.), improved bus stops, landscaping (trees, bioswales for stormwater management, etc.), lighting, and public art. A few projects also included new or restriped bike lanes, shared lane markings, and/or bike parking.

PSU researchers Jennifer Dill, Jenny Liu and Marisa Zapata evaluated two main components: 

  • A quantitative analysis on the economic benefits of 12 active transportation projects on busy commercial streets.
  • A qualitative assessment of the projects to help tell the story and understand other benefits and impacts of each project. This was conducted through stakeholder interviews, online surveys, and existing feedback recorded from other projects (intercept surveys, surveys of residents of TODs, etc).

"Taking both a quantitative and qualitative approach was important, so we could better understand the numbers and hear directly from the people, including customers and business owners, about the value of the projects. However, our work was done mainly in 2020, so we had to get creative in how we found those people, including an online survey and social media.," Dill said.

Overall, the research team found positive effects on business activity in the retail and/or food sectors, demonstrating that the potential economic benefits are not just in more urban parts of the city of Portland:

  • 75% of the project locations saw measurable economic gains in the food or retail industries after implementation.
  • Layering complementary investments (e.g. light rail stations and transit oriented-development) has the potential to yield the greatest benefits.
  • The projects that did not see positive effects tended to have higher traffic volumes and/or speeds. Projects are more likely to reach their full potential when they reduce the effects of an auto-oriented environment and create places for walking that are also less stressful and more comfortable.

"The findings reveal that these types of investments can have positive outcomes in places outside of downtown and inner Portland, particularly when coupled with other planning and infrastructure investments, but that we do need to address the negative effects of high speed, multi-lane arterials," Dill said.

Together they help us understand many of the benefits of these recent active transportation projects that used regional flexible funding in the past. One of the most important outcomes of the study is informing the region’s decision makers, business owners, and the general public in the recent public comment period for Metro’s Regional Flexible Funding Allocations (RFFA) for transportation projects. With 29 project proposals on the table, it’s important to have the context and data on what has been effective in the Portland region.

Incorporating transportation into the land development process is a big undertaking, with many important angles to be considered. Researchers are translating NITC research on this theme into a popular, easy-to-understand graphic format: comics. Led by an interdisciplinary team at Portland State University and the University of Arizona, they're illustrating transportation considerations in the land development process as a comic to reach a broader audience on this critical topic. 

Related: Read about the NITC Research Roadmap on Transportation and Land Use.

Still in development (the images here are early working drafts, illustrated by PSU student Joaquin Golez and Portland, OR illustrator Ryan Alexander-Tanner), the comics are based on research findings from several projects funded by the National Institute for Transportation and Communities (NITC). The project team is working with readers at neighborhood associations and nonprofits to test this unique approach in sharing research findings. We interviewed three of the project team members Kelly Clifton of PSU, Ryan Alexander-Tanner and Susan Kirtley of PSU to hear how it's going.

Can you share more about your body of research on transportation and land use that sparked the idea for this comics project?

Kelly Clifton

I first started thinking about how we can better coordinate land development and transportation when I was doing my dissertation in the late 90s, but I didn't really have an occasion to do any funded research until I came to Portland in 2010. My very first project on this topic was funded by our U.S. DOT-supported program NITC and Metro, our regional body that governs transportation and land. We looked at system development charges because we wanted to know whether the different communities within our region were headed to more auto oriented built environments or not. At the time, Kristi [Currans] was a Masters student at PSU and she did her thesis on this topic. Lucky for me, she stayed on and did her PhD with me. Since then we’ve done five or six projects together, maybe more! Notably we did a big project for CalTrans looking at these questions for affordable housing and impacts on residents. We’ve done a lot of work with the City of Portland, revamping how they're coordinating transportation and land development. More recently, we’ve started looking at how we account for scooters and uber and rideshare and all of these new transportation options.

What unique strengths do project team members bring to this project?

Kelly Clifton

Kristi and I are bringing the technical know-how of transportation and land use, but I’ve always been interested in interdisciplinary projects and combining different talents to tackle a problem. Susan is coming from English and directing PSU’s comic studies program, and Ryan is a local professional comic artist and illustrator. And then we have a Master of Fine Arts student who's going to do a lot of the heavy lifting in terms of the artwork.

Ryan Alexander-Tanner

This is very much in line with my body of work in comics. Earlier in my career, Columbia University hired me to illustrate a book on teaching, and after working closely with the author for over a year I internalized the core message of being a student of your students. I learned how to take in a lot of information and reinterpret it into this accessible medium of comics, and that project helped me create a process for myself. In our informal sessions together I’m repackaging Kelly and Kristi’s expertise combined with Susan’s background as an academic in comics. I enjoy the role of mediating the collaborative process. 

Susan Kirtley

As Ryan mentioned, I’m coming at this as a comics scholar. I’ve done research in comics history and I bring with me this interest in visual rhetoric, and I've been very passionate about the potential for comics pedagogy –teaching with and through comics. I feel very strongly that comics have unique potential to inform and educate and entertain, so that's always something that appeals to me. This project is particularly appealing in that I get to learn all kinds of cool stuff, but also think more about that process of how do we teach with comics?

Kelly Clifton

Normally when I'm doing a research project I have an idea, and although we don't know what the outcome is going to be, we do know what the process is going to be. But I’ve never made a comic before, and I don’t know the process. Susan and Ryan offer these checks and balances, and I think everyone's learning something new through this project, which is, I think, really cool.

What do you see as barriers to communicating research? 

Kelly Clifton

The first barrier is academic training. We're not really trained on how to talk to a broader audience. We’re very much taught how to talk to each other, to be very cautious in the language we use, and to not over generalize. I’m always very reserved about overstating the implications of work, which is important - but, how can we strike a balance to reach a general audience? Another barrier is retraining my brain. How do you tell a story without all the inherent complexity in research? And how do you adjust based on your audience, which could be academics, decision makers in policy and practice, students, and then the general public? There is no one way to communicate that would hit all those groups.

Susan Kirtley

As academics we are encouraged to talk amongst ourselves, to publish in peer-reviewed scholarly journals in the insular university press world. Not only is it what we’re encouraged to do, it’s also how we’re valued and evaluated in terms of our performance and consideration for tenure. There's a lot of great research that's happening, but it’s not necessarily being shared with a wider audience. How can that form of communication be incentivized to change the norm?

Why do you think it is so important for universities to communicate research findings in new innovative ways like comics?

Ryan Alexander-Tanner 

I'm hearing this over and over in my work for universities and in the public health field. They say ‘we're insulated, and we do all this work and nobody reads it, no one engages with it.’ And while I don't think comics are the only method, I do think they're an effective method. We're in this media bombardment era where you're getting slammed with articles, podcasts, talks all the time. It’s hard to break through the noise.

Susan Kirtley

Working with students we talk a lot about going to the source of the information and why that's important, particularly in an era where there's so much misinformation. The expert tells the journalist, and then the journalist tells someone else, and then Buzzfeed picks it up. By the time it gets to that point it's lost the original focus and findings. With Kelly and Kristi, we have the opportunity to tap into the expert source right here and bring it to life with visuals.

Kelly Clifton

Universities really are challenged now, and research in particular, to prove their value to the public. What is the value of a university education, not just to the individual, but to society? A shift to prioritizing communicating your work more broadly is about getting the information out there, but also it’s just showing what we do at universities and how it can have an impact beyond just academia.

What is unique about comics as a medium? What does it have to offer that other mediums do not? Would you agree that comics offer a form of education that suits different learning styles?

Ryan Alexander-Tanner

Yes, absolutely. There is a type of learner that comics are their ideal medium. More important though is distilling your message down to the main idea. Like, what is the point of sharing that message? I don't think the medium is as important as the message itself. But there are many people that wouldn't read a research article, but would read a comic about research. The pairing of text and image is really effective. It can activate multiple parts of your brain. And the concise nature of language in comics lends itself to focusing on the main message. Comics can also break up information into bite-size pieces, and even if you’re stringing them together into something that's long…it just makes it more accessible. Integrating that creative element into something that's academic or factual is powerful. In a way, showing rather than telling is also an economical use of the learner’s time.

Susan Kirtley

I agree with all of that. You can do things with comic art that you can’t do with any other medium. The interplay of text and art together makes it unique, but also particularly well suited to an educational environment. Some folks are visual learners, and comics appeal to them. Comics invites the reader in and makes it interactive. Comics creator Scott McCloud talks about this, between the panels, the reader has to take this really active stance to interpreting and understanding the progression in the gaps between panels. Comics ask us to engage in the story in a way that no other medium does. There are so many unique things about comics that make them particularly well suited for communicating.

Ryan Alexander-Tanner

In the past, a lot of time has been spent trying to validate comics. We’re in a good place now where it’s generally accepted that comics are fun to read and an effective way to communicate. I’ve heard many times things like, ‘You know I had to read 15 books last semester, and your book stood out because it was a comic book and more engaging to read.’

Kelly Clifton

My biggest motivation was to get this out to a completely different audience. If policymakers or transportation students want to read the comic, great! But I really want community and advocacy organizations, the public to be engaged by this format.

What are you hoping to accomplish by communicating transportation land use research through comics? Who is your target audience?

Kelly Clifton

We have two test reader groups that we’ve arranged. One through a Portland neighborhood association and another through Tucson’s Living Streets Alliance who works closely with the Latin community there. And that's exactly who my target audience is: people who are not subject matter experts on transportation and land use, but they experience the impacts on a daily basis. Everybody understands sitting in traffic. Everybody understands getting cut off by someone while you're riding your bike. Everybody understands the challenges of walking on unimproved roads with no sidewalks. But what they might not understand is how do things get this way? More importantly, how do we advocate for change?

What aspect of this project are you most excited about? What do you expect to be most challenging?

Kelly Clifton

What’s most exciting for me is learning new things every time the team gets together. It’s my favorite part of the week! Maybe when the comic is done, it will be anti-climactic because the process itself has been so exciting.

Susan Kirtley

I would agree with you Kelly, I love learning new things, and so this process of translation between research and comics has been so much fun. As a teacher I can’t help but think ‘Ooh this is something I could talk about in class’ or ‘I could do an activity related to what we're doing’. 

Ryan Alexander-Tanner

It’s the collaboration for me. We’ve been approaching this as very non hierarchical, and learning a lot from each other. One thing that's very exciting is creating this opportunity for our student artist, Joaquin Golez. A lot of my work as a teacher has been trying to provide opportunities for students interested in comics that I didn't have access to when I was in college. If there had been an opportunity like this, when I was in school, it would have changed my life. Something that is both exciting and challenging is we're going to have to let go and support our student in taking the reins. Seeing their creative interpretation of all the stuff we put together - that's thrilling to me.

Can you share anything about what you’ve developed so far, and any similar initiatives at PSU?

Kelly Clifton

We’ve been in the thick, messy part of it. I’ve just been tossing research findings at them and then they've been grabbing it and throwing it back at me. Sort of playing hot potato, like: what's the structure of this going to look like? How are we going to fit the narrative into that structure? After the comic is published we’ll also do a workshop in the fall at Portland State to talk about this process and the power of comics to communicate research.

Ryan Alexander-Tanner

We are hoping to have a completed comic by the end of summer. We’re making a printed comic book and it's going to consist of three articles which will all be available on the web too.

Susan Kirtley

This project speaks to the potential of Portland State. We have really strong faculty doing interesting research, and we also have the Comic Studies program. Portland has so many amazing local creators like Ryan, so I think this project speaks to this intersection of comics and academics while tapping into the city’s resources as a hub of comics. Moreover, we have amazing students who can create them!
