Exploring Bicycle Accessibility And Equity In Portland, Oregon, Jenny H. Liu

PSU Transportation Seminars

As urban areas across the country are investing in bicycle and pedestrian infrastructure to promote environmentally sustainable transportation and to develop livable communities, many have pointed to improvements in environmental quality, economic development and public health as potential positive outcomes. While these outcomes of active transportation infrastructure are relatively well documented, it is also known that both transportation and environmental amenities are typically unevenly distributed in the urban context. Studies show that those who are the most socioeconomically disadvantaged (i.e. low income, people of color, etc.) are also those who disproportionately experience transportation disadvantages.

This study contributes to the existing …

How Commute Mode Choices Can Control Stress Levels, Liu-Qin Yang

TREC Project Briefs

This research integrates perspectives from transportation and psychology research by focusing on the relations between commuting stress, commuting mode choice, and consequences of such choice for commuters’ health, travel safety, and work performance. To fill the gaps in the transportation and psychology literatures, the project addresses two key research questions:

1) Under what circumstances workers experiencing commuting stress are more likely to commute via car vs. public transit vs. bicycle vs. on foot?

2) What are the different implications of choosing different commuting modes for commuters’ mental and physical health?

By encouraging students to consider behavioral interactions of roadway users, these exercises can provide students with field …

Growth Without Displacement: A Test For Equity Planning In Portland, Lisa K. Bates

Urban Studies and Planning Faculty Publications and Presentations

Portland, Oregon, is considered a pioneer of regionalism, integrated land-use and transportation planning, and sustainability as a criterion for planning policy. After four decades of land-use planning, Portland has a national and international reputation for urban livability and climate change mitigation. While these successes are laudable, in the past decade Portland’s underrepresented and underserved communities have been raising a voice to demand that planners address issues of income and racial inequality. In response to and in collaboration with communities, over the past five years Portland’s Bureau of Planning and Sustainability (BPS) has adopted an equity strategy with a racial justice …

Cascadia Connect: Car-Free Access To The Outdoors, Kara Boden, Brandon Crawford, Matt Gray, Tony Lamb, Maricelith Valencia, John Whitman

Master of Urban and Regional Planning Workshop Projects

As outdoor recreation areas in Oregon become more popular, increased auto-related congestion results in strained resources, environmental degradation, and diminished visitors’ experiences. This project proposes policies, strategies, and a variety of approaches to help transportation agencies and land managers facilitate car-free access to outdoor recreation areas. The plan also proposes approaches to increase access to recreation areas for transit-dependent visitors and under-represented communities who face significant barriers to access today. The Background Report includes data; interview, survey and focus group themes; site visit findings; and personal travel anecdotes.

Empowering Portland's Youth To Choose Car-Free Mobility, Autumn Shafer, Jared Macary

TREC Project Briefs

Little is known from research about how to motivate youth to choose non-car mobility, especially specific Portland-area youth. Understanding the current attitudes, beliefs, and behaviors of youth in relation to non-car mobility contributes to the sustainability of a long-term transportation system. Transportation system-related beliefs and behaviors of youth are likely to influence their willingness to access and support transportation services as adults. Today’s youth are tomorrow’s riders, bikers, walkers, voters, and transportation planners. Thus, it is important to develop age-appropriate messaging strategies and tactics that promote youth non-car mobility.

This project seeks to build on the sparse national and non-Portland …

Oregon Manufacturing Extension Partnership: Economic Impact Analysis -- January 2018 Update, Emma Willingham

Northwest Economic Research Center Publications and Reports

The Hollings Manufacturing Extension Partnership (MEP), founded in 1988, is a network of non-profit agencies staffed by industry professionals and consultants. Historically, MEP has sought to increase the competitiveness of small to mid-size enterprises (which as a group comprise 99% of all U.S. manufacturing firms) by providing expert guidance and access to resources. In recent years, the severe economic recession sparked increased interest in the strength of the manufacturing sector, due to its longtime status as one of the major drivers of the domestic economy.

How Do Stressed Workers Make Travel Mode Choices That Are Good For Their Health, Safety, And Productivity?, Liu-Qin Yang, Brad Wipfli, Lee Cyr, Kristina Marie Currans, Liming Wang

TREC Final Reports

It is well recognized in transportation and psychology research that commuting stress has consequences for commuters' travel safety, home environment, and work performance. Little research has addressed questions involving the possible interdependence between work stress, family stress, and commuting stress: Do workers having many demands from work and family life get more stressed out from a stressful commute? Or do stressed workers try to cope with work and non-work stress by choosing more relaxing travel modes?

This proposal integrates the perspectives from transportation, psychology, and health science by focusing on the relations between commuting stress, commuting mode choice, and consequences …

Responsible Pet Ownership: Dog Parks And Demographic Change In Portland, Oregon, Matthew Harris

Dissertations and Theses

Dog parks are the fastest growing type of park in U.S. cities; however, their increasing popularity has been met with increasing criticism of pets in public space. Dogs have shown to be a deep source of neighborhood conflict, and the provision of dog parks, or off-leash areas, is a seemingly intractable controversy for city officials. In 2003, Portland, Oregon established a network of 33 off-leash areas which remains the second largest both in count and per capita in the country. The purpose of my research is to understand the public debate over off leash dogs during the establishment of Portland's …

Improving Bicycle Crash Prediction For Urban Road Segments, Krista Nordback, Sirisha Kothuri, Wesley Marshall, Geoff Gibson, Nick Ferenchak

TREC Final Reports

The 2010 Highway Safety Manual (HSM) provides methods for predicting the number of motor vehicle crashes on various roadway facilities. However, it includes only a rudimentary method for predicting the number of bicycle-related crashes. Despite research demonstrating that bicycle volume is an important factor in estimating number of bicycle crashes, the method does not include the volume of bicyclists using the roadway. To remedy this, this project will investigate the potential of various simplified methods to include bicycle volumes in future versions of the HSM. By studying locations where bicycle traffic volumes, motor vehicle traffic volumes, bicycle collisions, and roadway …

The report looks at current and past bike share members, along with those who were involved in some type of equity-based outreach program. The findings draw from a survey intended to reach lower-income and/or people of color known to have engaged in bike share, either through membership or participating in events such as organized rides, in the same three cities studied in the resident report …

New Probe Data Sources To Measure Cycling Behavior And Safety, Christopher Cherry

PSU Transportation Seminars

Emerging probe data sources from smartphones on on-board devices are able to measure behavior of cyclists with very high resolution. From this, for the first time, we are able to measure relatively precise behavior that allows new insights into exposure, route choice, safety behavior, or technology choice. Probe data, merged with other data sources, can begin to develop a more complete picture of cyclists on-road behavior.

This presentation will offer examples of analyses done to investigate cyclists behavior using app-based and on-board GPS data in the context of individual cyclists behavior (i.e., app users) and behavior of bikeshare users (i.e., …

Assessing The Impact Of Land Use And Travel On Carbon Dioxide Emissions In Portland, Oregon, Zakari Mumuni

Dissertations and Theses

The negative consequences of sprawling metropolitan regions have attracted attention in both academia and in practice regarding how to better design settlements and alter travel behavior in a quest to curtail vehicle emissions. Studies that have attempted to understand the nexus between land use, travel and vehicle emissions have not been able to address the issue of self-selection in a satisfactory manner. Self-selection occurs when households choose their residential location based, in part, on expected travel behavior. This non-random experience makes the use of traditional regression frameworks that strongly rely on random sampling, unsuitable. This replication study's purpose was to …

"Naturally Occurring" Or "Until Market Speculation Starts": Investigating The Precarity Of Affordable Rental Housing And The Potential For Displacement Along Planned Transit Lines, Lisa K. Bates

Urban Studies and Planning Faculty Publications and Presentations

New transit infrastructure is a double-edged sword for low-income renters: one the one hand, increased mobility supports access to jobs and critical services; but if transit-oriented development fails to include and preserve affordable housing, they may be pushed out by rising rents. The question of whether public investments spur gentrification and displacement have created intense controversy around planned transit extensions in our region. My research on precarious rental housing illuminates the specific mechanisms of housing displacement and challenges for housing affordability in the single-family/duplex and the large multifamily rental market. The loss of low-cost housing is occurring even without new …

TREC Project Briefs

This NITC study offers a new methodology for evaluating the before-and-after effects of roadway space reallocation projects.

Evaluation Of Roadway Reallocation Projects: Analysis Of Before-And-After Travel Speeds And Congestion Utilizing High-Resolution Bus Transit Data, Miguel A. Figliozzi, Travis B. Glick

TREC Final Reports

The traditional process of identifying corridors for road diet improvements involves selecting potential corridors (mostly based on identifying fourlane roads) and conducting a traffic impact analysis of proposed changes on a selected roadway before implementing changes. The evaluation of roadway reallocation projects should include the analysis of traffic volumes, level of service, speeds, queue lengths and bus operations. There are tools and equipment to evaluate effectively traffic volumes and level of service changes in before-and-after studies. However, the detailed evaluation of speed and queue length distributions along a segment are significantly more cumbersome. In addition, the exhaustive evaluation of bus …

Using The Planning Process To Mitigate Climate Change, Keith Bartholomew

TREC Project Briefs

This research evaluates how Oregon’s SB 1059 and California’s SB 375 have integrated climate change mitigation strategies into local planning processes, and seeks to understand how transportation planning can help slow climate change.

Preserving Housing Choice And Opportunity: A Study Of Apartment Building Sales And Rents, Seyoung Sung, Lisa K. Bates

Urban Studies and Planning Faculty Publications and Presentations

NOAH sales show precariousness of this rental housing at a regional scale.

• Active transactions of multifamily rental properties have been disproportionately NOAH. There have been over two thousand transactions of NOAH buildings in the Portland metro area from 2006 to 2017 — over 68,000 units of housing. These sales are accelerating, with over 20 percent occurring in just the last 18 months.
• Sales prices for multifamily rental properties have increased substantially, making preservation of affordable rents more challenging. Regionally, the average sale price increased by 78 percent between 2010 and 2017; during this period there was a 43 percent …

Accessing Blue Spaces: Social And Geographic Factors Structuring Familiarity With, Use Of, And Appreciation Of Urban Waterways, Melissa Haeffner, Douglas Jackson-Smith, Martin Buchert, Jordan Risley

Environmental Science and Management Faculty Publications and Presentations

Are urban waterways amenities, and if so, are there inequities in household access? While urban waterways represent a potential site for access to nature within the urban environment, there have been few studies on the accessibility and interactions with water features in particular, what we refer to as “blue spaces." This study drew on a sample of households in Northern Utah living in neighborhoods with a nearby river or canal to ask if local waterways provide positive impacts to households and if proximity to them increased the likelihood of households spending time at them and being familiar with them. We …

Deconstruction In Portland: Summary Of Activity, Emma Willingham, Peter Hulseman, Mike Paruszkiewicz

Northwest Economic Research Center Publications and Reports

On October 31st, 2016, the City of Portland instituted an ordinance requiring the deconstruction of all residential homes and duplexes built prior to 1917 or possessing a historical designation. Deconstruction is a relatively new industry, and with this local regulatory encouragement, several new contractors became certified to participate in the expanded market. This report provides background on the industry, largely from the 2016 report researched and written by the Northwest Economic Research Center (NERC) in anticipation of the requirement, and an examination of what has occurred in the year following the ordinance’s passage, using deconstruction and demolition permit data and …

Building Planner Commitment: Are California’S Sb 375 And Oregon’S Sb 1059 Models For Climate-Change Mitigation?, Keith Bartholomew, David Proffitt

TREC Final Reports

California’s Sustainable Communities and Climate Protection Act (SB 375) and the Oregon Sustainable Transportation Initiative (SB 1059) have made them the first states in the nation to try and reduce greenhouse gas (GHG) emissions using the transportation-planning process. Evaluating how these pioneering laws have changed local planning processes – as well as plans themselves – in each state provides insight into the laws’ effectiveness at changing development patterns in a way that reduces GHG emissions, without waiting decades to see the effects in the built environment. Both states’ laws require metropolitan planning organizations (MPOs) and the municipalities that comprise them …

Webinar: Transportation Benefits Of Parking Cash-Out, Pre-Tax Commuter Benefits, And Parking Surtaxes, Allen Greenberg, James Choe, Sonika Sethi, Colleen Stoll

Multiple strategies exist to level the playing field between travel modes and allow employees to select the travel option most beneficial to them without suffering a financial penalty. The U.S. Department of Transportation, Federal Highway Administration sponsored a study to understand the effect parking cash out, pre-tax commuter benefits, and parking surtaxes can have on congestion, emissions, and other driving-related externalities. The study is part of the Administration’s ongoing efforts to increase awareness of solutions to address the transportation issues affecting communities …

Municipal Co-Distribution Of Goods – Business Models, Stakeholders And Driving Forces For Change, Olof Moen

PSU Transportation Seminars

The presentation provides background information and illustrates driving forces of the development of municipal co-distribution of goods in Sweden. The business model is “somewhat unique” to Sweden, given the country’s comprehensive welfare sector through which local governments are often the main transport buyers in smaller municipalities without industries or commerce. In this respect, Sweden has been a pioneer in streamlining public administration at all levels replacing manual work procedures and paperwork with the use of computers and digital information, with an overall aim to allow for spending on social and political reform policies. The main business model used in municipal …

Advisory Bike Lanes In North America, Michael Williams

PSU Transportation Seminars

Despite being used successfully for decades in Europe, Advisory Bike Lanes are an emerging facility type in North America and can be an effective tool for communities wishing to provide bicycle lanes on streets that are otherwise too narrow to accommodate them. This talk will introduce the concept and operation of advisory bike lanes and look at some lessons learned from the early installations of this facility in the U.S. and Canada.
