OVERVIEW

There is nationwide interest in supporting sustainable and active transportation modes such as bicycling and walking due to the many benefits associated with them, including reduced congestion, lower emissions and improved health. Although the number of bicyclists is increasing, safety remains a top concern. In urban areas, a common crash type involving bicycles at intersections is the “right hook” where a right-turning vehicle collides with a through bicyclist. While geometric treatments and pavement markings have been studied, there is a lack of research on signal timing treatments to address right-hook bicycle-vehicle conflicts.

Addressing Bicycle-Vehicle Conflicts with Alternate Signal Control Strategies, published in April 2018, is the first study to explore bicycle signal control strategies for addressing bicycle-vehicle conflicts. This study analyzed the operational impacts of traditional...

Inaccessible Accessibility: low-income households and barriers to the “new American dream”

The video begins at 0:20.

Topic: Inaccessible Accessibility: low-income households and barriers to the “new American dream”

In many ways, the resurgence in demand for housing in highly accessible and walkable neighborhoods can be viewed as a triumph of planning and policy efforts to reinvest in walkable urban neighborhoods that support active travel. However, increased demand has resulted in price premiums that can make location-efficient housing choices more difficult for low-income households. This research uses data from a survey of recent movers in six U.S. cities, including Portland, to explore the extent to which households of different economic means are able to choose housing locations that match their accessibility and transportation preferences.

Bio: Arlie Adkins is a PhD candidate and adjunct instructor in the Toulan School of Urban Studies and Planning at Portland State University. His dissertation research focuses on better understanding how people make decisions about non-work travel behavior in the context of a new home. Arlie holds a master’s degree in city planning from UC Berkeley. He previously worked in TriMet’s project planning department as a community affairs specialist and at Flexcar in Washington, DC.

Webinar: Individual Wayfinding in the Context of Visual Impairment, Blindness, and Deafblindness

 

PRESENTATION ARCHIVE

OVERVIEW

In this presentation we will highlight our past research on human indoor-outdoor wayfinding on an urban college campus. Our work is aimed at facilitating independent travel for people with blindness and low vision. Our research was funded by two successive grants from the National Institute for Transportation and Communities/US Department of Transportation. One of the central research questions sought to capture wayfinding preferences, information needs, and lived experiences of blind and low-vision pedestrian travelers. The projects afforded close collaboration with external partners, and foremost the American Printing House for the Blind. Our focus in the presentation will be on the...

Webinar: Eliminating Cash Options for Public Transit Fares: Costs, Benefits and Equity Impacts

PRESENTATION ARCHIVE

OVERVIEW

Many transit agencies plan to automate their fare collection and limit the use of cash, with the goals of improving boarding and data collection while lowering operating costs. Yet about 10% of adults in the United States lack a bank account or credit card, and many either rely on restrictive cell-phone data plans or don’t have access to internet or a smartphone. 

This webinar will present part of a larger research project exploring these issues in the cities of Denver, Colorado, and Eugene and Portland–Gresham, Oregon. In this part, we explore the tradeoffs between reducing cash acceptance, ridership and the costs of fare collection systems. How much does it save to reduce cash acceptance, verses ridership and equity impacts?

We will also present a cost-effectiveness framework that combines a qualitative and quantitative analysis and use this model to explore case scenarios in our three cities. The model shows that adding a retail network to...

Topic: Skateboarding as Transportation: Findings from Exploratory Research

Bio: Tessa Walker is currently completing her thesis on non-motorized transportation and qualitative research methods with supervision from Dr. Jennifer Dill and Dr. David Morgan. For more information on her thesis research please visit the Skate Study PDX website (http://www.skatestudypdx.wordpress.com). Tessa has previously worked in town planning in Vermont, sustainability auditing in Massachusetts, and in bicycle and pedestrian transportation research with the Family Activity Study at PSU. She is currently an intern at the public opinion research firm DHM Research, and she will be a 2013-2014 Hatfield Fellow.

Webinar: Exploring Data Fusion Techniques to Derive Bicycle Volumes on a Network

PRESENTATION ARCHIVE

OVERVIEW

Planners and decision makers have increasingly voiced a need for network-wide estimates of bicycling activity. Such volume estimates have for decades informed motorized planning and analysis but have only recently become feasible for non-motorized travel modes.

Recently, new sources of bicycling activity data have emerged such as Strava, Streetlight, and GPS-enabled bike share systems. These emerging data sources have potential advantages as a complement to traditional count data, and have even been proposed as replacements for such data, since they are collected continuously and for larger portions of local bicycle networks. However, the representativeness of these new data sources has been questioned, and their suitability for producing bicycle volume estimates has yet to...

Are Bicycling and Walking “Cool?”: Adolescent Attitudes about Active Travel

The video begins at 0:10.

Summary: The declining rates of physical activity among children, particularly adolescent girls, are well-documented, yet there has been insufficient research into the attitudes about health behaviors, particularly active travel, of the children themselves. Tara's research explores attitudes about active transportation among children aged 4-17 years and examines how perceived ability, self-efficacy, and sensitivity to certain environments or facilities vary across gender and age of the children. She utilises data from the Family Activity Study, a multi-year longitudinal intervention study in Portland, Oregon, in which 490 children answered surveys regarding their attitudes, perceptions, and behaviors about traveling by walking, bicycling, or being in a car.
