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,...

Shared micromobility programs for e-scooters and bike share are becoming more common each year. How can we make sure they aren’t just being used for fun, but they’re also being prioritized for those who need a quick, affordable and accessible way to get around? A team of researchers has collected documentation about equity requirements from 239 shared micromobility programs across the U.S. and compiled all the data into an online dashboard, which city officials can use to find what other similar-sized cities are doing. Equity efforts in one city may pave the way for expanded opportunities in another.

Keeping a focus on equity can make this new technology accessible and affordable, and could improve the lives of people with disabilities, people with low incomes, those who don't have access to a smartphone, and those who live in neighborhoods without good transit access. Led by the University of Oregon's Anne Brown and Amanda Howell, with Hana Creger of The Greenlining Institute, the latest report from the National Institute for Transportation and Communities (NITC) took steps toward...

Are e-scooters just the first sign of a shared-mobility revolution? If they are, then researchers at the University of Arizona intend to make sure that the emerging transportation system has functional models on par with other modes of transportation. In 2018, approximately 100 U.S. cities had already launched shared e-scooter programs, accounting for 38.5 million trips. However, the models to manage e-scooter sharing are only recently being developed. In a project funded by the National Institute for Transportation and Communities (NITC) and led by Dr. Jianqiang Cheng, the research team set out to develop data-driven, decision-making models for shared-mobility system design and operation in Tucson, Arizona.

"The decision making process for e-scooter companies is complex. One of the first questions is where to locate the scooters – In the transportation network, where do e-scooters need to be placed to meet demand? The second question is how to distribute them. It gets more complicated when you introduce different electric charging methods, so that some scooters are being collected by paid contractors and others are being charged by customers, through incentives," Cheng said.

As the researchers see it, the main benefits of shared mobility are threefold:

  1. ...

Would monetary incentives encourage more people to buy e-bikes? 

Portland State University (PSU) researchers are examining how purchase incentive programs can expand the current e-bike market, and the latest product to come out of this research is a white paper released earlier this month: “Using E-Bike Purchase Incentive Programs to Expand the Market – North American Trends and Recommended Practices (PDF)

The paper offers methods of identifying the most effective program structure for the incentive provider's priorities, and helpful information on how to administer and track the program.

In recent years, shared electric scooters (e-scooters) have taken cities around the world by storm. But how are people using this new mode of transportation? Seeking to understand the potential impacts of e-scooters on land use, infrastructure and sustainability goals, researchers have some new interesting data to share on e-scooter users, exploring the interplay between demographics, behaviors and trip purposes.

Funded by the National Institute for Transportation and Communities (NITC) and led by Kristina Currans and Nicole Iroz-Elardo of the University of Arizona and Reid Ewing of the University of Utah, the study combines a user survey with on-the-ground observations to characterize the use and safety of e-scooters. The research team also included students Dong-ah Choi,...

For governments and clean energy advocates looking to encourage people to use e-bikes for transportation, a new online tool from Portland State University researchers offers an overview of the existing incentive programs in the United States and Canada.

The E-Bike Incentive Programs in North America table tracks e-bike purchase incentive programs and key details that can provide a point of reference for the development of future e-bike incentive programs and policies, or for further research on the topic. Read a recent article about the tool in BikePortland.

John MacArthur, researcher at PSU's Transportation Research and Education Center (TREC), led the development of the tool with the help of PSU transportation engineering masters student Cameron Bennett, a 2021 Dwight D. Eisenhower Transportation Fellow.

COMPARING TYPES OF E-BIKE INCENTIVE PROGRAMS

While the tracker shows a wide variety of approaches, Bennett identified Saanich, BC as demonstrating an especially...

Paper Bike Share Equity Briefs Arranged on a Table
John MacArthurNathan McNeil and Joseph Broach, Portland State University

Last year, Portland State University’s Transportation Research and Education Center (TREC) released a 130 page evaluation comparing equity-oriented programs from over 70 U.S. bike share systems across the U.S. Bike share being a relative newcomer to the transportation system, the research team was not surprised to find that approaches to equity programs ranged widely. In the latest installment, funded by the Better...

Advances in transportation technology — e-scooters and bike share, Lyft & Uber, and autonomous vehicles — are beginning to have profound impacts on cities. New mobility is changing not only how we travel, but also urban form and development itself. In the near future, we can expect differences in what public transit looks like, the layout of cities, and the places we spend our time. In turn,...

Our National Institute for Transportation & Communities (NITC) research program has awarded grant funding for a new series of Small Starts projects.

The latest Small Starts Grant projects, evaluated by the NITC Advisory Board and selected by NITC's Executive Committee, will explore mobility impacts of construction workzones, transportation equity and barriers for low-income travelers, and the widespread impacts of emerging technologies like e-scooters and ride hailing.

This annual NITC funding program is a unique opportunity to tackle small-scale ($20,000 or less in scope) research projects. In contrast to our larger, annual flagship program ($30–150K), Small Starts enables us to include researchers who:

  • Bring a diverse, interdisciplinary perspective

  • Offer a new voice in the field, whether they’re untenured faculty or a researcher who has not received a NITC grant before

  • Want to kick-start a larger project by first tackling an exploratory study smaller in scope

THE...
