Researchers Jennifer Dill, Jiahui Ma, Nathan McNeil, Joseph Broach and John MacArthur of Portland State University have published a new article in the November 2022 issue of Transportation Part D: Transport and Environment. The open-access article, "Factors influencing bike share among underserved populations: Evidence from three U.S. cities," examines bike share use and interest among lower-income residents and people of color in New York, Chicago, and Philadelphia.

There is evidence that lower-income and people of color (POC) in the U.S. do not use bike share as much as higher-income and white people. Using data from residents living near bike share stations in New York, Chicago, and Philadelphia, the paper examines reasons for these disparities. Researchers looked at many factors that might explain bike share use and interest in lower-income, racially diverse, traditionally underserved neighborhoods. They focused on residents who live near bike share stations, so that proximity would not be a barrier.

A few key findings:

  1. People who are not members, but are interested in using bike share, including POC, are motivated to use bike share for fun, recreation, and social reasons (as opposed to utility).
  2. Knowledge of bike share and receiving information from interactive sources (for example,...

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.

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...

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...

Our multi-year study on automated transit fare collection offers a key finding that won't surprise you: Despite the convenience, the rush toward cashless fare systems has created barriers for lower-income riders seeking to use transit. Results from focus groups, surveys, and a review of current transit agency practices suggest that continuing to accept cash is a crucial way to keep transit accessible. However, dealing with cash has drawbacks: it’s time intensive and expensive. Using a detailed cost-benefit model, the researchers explored the costs for agencies to maintain some cash options and found that some simple approaches can be quite effective. The best bang for the buck? Cash collection on board buses.

Launched in 2019, the research project "Applying an Equity Lens to Automated Payment Solutions for Public Transportation" was supported by a Pooled Fund grant program from the National Institute for Transportation and Communities (NITC) and conducted at three universities: Portland State University (PSU), the University of Oregon (UO), and the University of Tennessee, Knoxville (UTK). The other funding partners were City of Eugene, OR, City of Gresham, OR, Lane Transit District, Clevor Consulting Group, and RTD (Regional Transportation District) Denver....

Proponents of advanced bikeways will point out a growing body of research on these facilities’ safety and benefits for cycling. They can now add another benefit: higher home values.

Research led by Jenny Liu of Portland State University looked at property around advanced bikeways in Portland, defined as bicycle boulevards, protected bike lanes and buffered bike lanes. She found positive effects on property values close to one of these bikeways and an even stronger effect where the network was denser.

Liu presents her research Wednesday at the annual meeting of the Transportation Research Board in Washington, D.C. Learn more or download the research paper.

For single family home sales, being a quarter mile closer to an advanced bikeway translated to a $686 premium, while increasing the density by a quarter mile represented a $4,039 premium. For multi-family homes, the effect of being close to a bikeway wasn’t statistically significant on sale price, but increasing the density of bikeways translated to $4,712 of value.

The research can inform policymakers who may question how much residents value bikeways and provide insight into siting decisions. “My results don’t necessarily say to put one here or not, but it does show there is indeed a...

In recent decades, Bus Rapid Transit (BRT) has gained popularity across the United States due to its relatively low costs of development (compared to the investment requirements of putting in a new light rail system, for example) and its potential to drive economic development.

However, there is a need for more comprehensive research devoted to understanding its economic impacts across various sectors.

NITC researcher Joanna Ganning is the lead author on a research paper that will be presented at the annual meeting of the Transportation Research Board this month, which seeks to estimate the effects of BRT stations on employment growth.

Using Longitudinal Employer-Household Dynamics data, Ganning and her research team investigated the impacts of BRT on employment changes of each major industry sector between 2002 and 2010.

The researchers analyzed employment data surrounding 226 BRT stations along nine BRT corridors which were opened during the study period, as well as employment data from equally sized areas around control points.

Metropolitan areas included in the analysis were Phoenix, Los Angeles, Kansas City, Las Vegas, Salt Lake City, New York City, Cleveland, Ohio and Eugene, Oregon.

With the presence or absence of BRT stations as the independent variable, the team found that BRT statistically significantly influenced employment change for just one...

Bicycle commuters represent a significant chunk of business consumers in Portland, Ore., one of America's most bike-friendly cities. OTREC research in the past year has provided data on how cyclists and other mode users patronize local businesses.

The final OTREC research report is available on the project pageLead researcher Kelly Clifton of Portland State University also presented her findings at the 2013 Oregon Active Transportation Summit in Salem.
The research found that bicycle consumers spend as much money, on average, as those who drive, and that local businesses can make an effort to attract this share of the market. The Plaid Pantry convenience store chain, a participant in the research, subsequently installed bike racks at 12 locations to make them more hospitable to cycling consumers, as first reported in a post on the Bike Portland blog.

Efforts to promote active transportation often come up against concerns, from business owners, that any shift away from automobile use will mean fewer customers or less revenue.
 
In fact, this research indicates that, for the most part, how much people spend has little to do with what transportation mode they use.
 
Lead researcher Kelly Clifton of Portland State University, in a recent project, "Consumer Behavior and Travel Mode Choices," does highlight some key differences between transportation modes. People arriving by bus, bike or on foot average more trips per month to convenience stores, supermarkets, drinking establishments and restaurants than do people arriving by car. They also spend more per month at all types of establishments except supermarkets, where the auto users’ greater spending per trip more than makes up for their fewer trips.
 
Clifton offered some preliminary...
