Skateboarding As Transportation: Findings From An Exploratory Study, Tessa Walker Nov 2013

Skateboarding As Transportation: Findings From An Exploratory Study, Tessa Walker

Dissertations and Theses

In recent decades skateboarding has expanded from recreation into a form of transportation. Skateboarders appear to use roadways much as other non‐motorized modes do. However, there is little academic research on the needs and characteristics of the skateboard as a mode. This research reports demographics, multi‐modal and travel behavior findings, and other data from an exploratory mixed‐methods study of skateboarding as a mode of transportation.

Dissertations and Theses

The study examines the influences of the Qianmen urban renewal project on its original residents, which is one of a few demonstration projects under the new policy orientation of urban renewal practices in Beijing, China, entering the new century. It employs "residential satisfaction" as an evaluative indicator to understand the residents' experiences before and after urban renewal. Seventy-two residents were interviewed. Among them, 25 remained in Qianmen; 20 relocated to Hongshan, a neighborhood in the central city area; 21 moved to Longyue, a neighborhood in one of the suburban areas; and 6 residents relocated to other locations.

The study found ...


Cyclist Compliance At Signalized Intersections, Sam R. Thompson Nov 2013

Cyclist Compliance At Signalized Intersections, Sam R. Thompson

TREC Friday Seminar Series

Although the running of red lights is perceived by motorists as a commonplace behavior for cyclists, little research has been done on the actual rates of cyclist compliance at signalized intersections. Furthermore, little is known about the factors that influence cyclist non-compliance. This research seeks to illuminate the rates of and reasons for infringement against red lights using video footage and survey data from cyclists in Oregon.


Why Doesn't That Traffic Signal Ever Turn Green? An Evaluation Of Roadway Markings For Cyclists, Stefan W. Bussey, Christopher Monsere, Peter Koonce Nov 2013

Why Doesn't That Traffic Signal Ever Turn Green? An Evaluation Of Roadway Markings For Cyclists, Stefan W. Bussey, Christopher Monsere, Peter Koonce

TREC Friday Seminar Series

Signalized intersections often rely on vehicle detection to determine when to give a green light. The 2009 Manual of Uniform Traffic Control Devices (MUTCD) includes an on-pavement marking and curbside sign that public agencies can use to indicate where cyclists should position themselves while waiting at an intersection. This presentation reviews the effectiveness of current markings, signs, and other methods used to help cyclists properly position themselves over detection.


From Transit Stop To Urbanity Node: Field Audit For Measuring Livability At The Transit Stop, Deni Ruggeri Nov 2013

From Transit Stop To Urbanity Node: Field Audit For Measuring Livability At The Transit Stop, Deni Ruggeri

TREC Final Reports

This research proposal addresses issues of livability at the transit stop. American transit systems have historically been “shoehorned” into existing street networks designed predominantly for cars and trucks. While much research exists on livability and walkability in the context of urban and suburban streets and blocks, bus stops are greatly understudied. This research focused on bus stops and aimed at analyzing their performance in terms of livability, with particular emphasis on perceptions. Our definition of livability was expanded to include considerations of safety and maintenance, cleanliness, imageability and vitality, which have been shown to affect people’s perceptions of livability ...

E-Bikes In The United States, John Macarthur Oct 2013

E-Bikes In The United States, John Macarthur

TREC Friday Seminar Series

Electric bicycles (e-bikes) are well established in China and other Asian and European countries but have yet to realize their potential in the United States, although recently the number of e-bikes has been growing. Research on the economic, operational, and safety issues of e-bikes in the U.S. is limited. This research aims in part to understand if different bicycling technology, in this case electric assist bicycles or e-bikes, can reduce barriers to bicycling and encourage more bike trips and longer bike trips, and increase the diversity of people bicycling, including people with a disability or chronic injury to bicycle ...


Using Indicators Projects As Prompts For Exploring Equity: A Case Study Of Greater Portland Pulse, Meg Merrick, Diane Besser, Shelia A. Martin Oct 2013

Using Indicators Projects As Prompts For Exploring Equity: A Case Study Of Greater Portland Pulse, Meg Merrick, Diane Besser, Shelia A. Martin

Institute of Portland Metropolitan Studies Publications

This paper describes the process that the Greater Portland Pulse (GPP) initiated to incorporate the measurement of progress toward social equity into the project. While equity may appear to be a widely accepted priority for communities, the GPP process created a dialogue that was sometimes contentious but also profoundly educational for the participants revealing some of the complexities, not only of the issue of equity, but the challenges (particularly the inadequacy of available data) and trade-offs that are inescapable when using conventional data sets.

Additionally, this paper discusses some of the consequences of a process that, while incorporating equity values ...

Data-Driven Illustrations For Climate Smart Communities Scenarios, Nancy Yen-Wen Cheng, Kim Ellis, Molly Vogt, Clint Chiavarini, Justin Houk, Brian Lockyear, Boyce Postma, Peggy Morell

TREC Final Reports

Public investment in transit and streetscape improvements can encourage private development, and subsequently increase transit ridership and reduce pollution. Portland, OR’s Metro regional government has developed investment scenarios designed to reduce light vehicle carbon emissions. Adopting a regional scenario requires public review and consultation with local governments who will implement the comprehensive plans and land-use regulations. Decision makers and residents need to understand potential benefits: ways in which targeted investment could generate more livable urban spaces while reducing greenhouse gases. Illustrations can show how the investments could shape the pedestrian experience through trees, street furniture, buildings, open spaces, etc ...

An Anthropology Of Urbanism: How People Make Places (And What Designers And Planners Might Learn From It), Brooke D. Wortham-Galvin Oct 2013

An Anthropology Of Urbanism: How People Make Places (And What Designers And Planners Might Learn From It), Brooke D. Wortham-Galvin

Institute for Sustainable Solutions Publications and Presentations

In their word play on what design praxis might succeed the New Urbanism movement in the United States, the July 2013 article “Newest Urbanism” in the Architect introduced to the uninitiated the concept of tactical urbanism. Defining tactical urbanism as "temporary, cheap, and usually grassroots interventions—including so-called guerrilla gardens, pop-up parks, food carts, and 'open streets' projects—that are designed to improve city life on a block-by-block, street-by-street basis," the article claims that it took this approach to shaping the city less than a decade to mainstream into the practices of US cities and firms alike. While Architect used ...


Durability Assessment Of Recycled Concrete Aggregates For Use In New Concrete: Phase I - Revised, Jason H. Ideker, Matthew P. Adams, Jennifer Tanner, Angela Jones Oct 2013

Durability Assessment Of Recycled Concrete Aggregates For Use In New Concrete: Phase I - Revised, Jason H. Ideker, Matthew P. Adams, Jennifer Tanner, Angela Jones

TREC Final Reports

The primary goal of this research project was to investigate the long-term durability of concrete incorporating recycled concrete aggregate (RCA) through accelerated laboratory testing. Overall it was found that modifications to standard aggregate testing and characterization standards were necessary for testing RCA. This included modifications to standard tests including ASTM C 128, C 305 and C 1260. It was found that the potential for alkalisilica reactivity did exist for new concrete containing RCA. The characteristics of the RCA also had a profound effect on ASR related expansion. RCA with a higher content of reactive coarse or fine aggregate (compared to ...


Making Streets Into Complete Streets: An Evidence-Based Design Manual, Marc Schlossberg, John Rowell Oct 2013

Making Streets Into Complete Streets: An Evidence-Based Design Manual, Marc Schlossberg, John Rowell

TREC Final Reports

The predominant approach toward street function on major roads in the United States is to emphasize mobility and throughput of vehicles. The “Complete Streets” movement challenges some of this paradigm, emphasizing that streets should accommodate multiple modes of travel and should often be considered destinations themselves. Often, efforts to transform streets into Complete Streets face resistance from both professional communities of traffic engineers and from the public that their design will reduce throughput and vehicle flow..Complete Streets advocates, in some cases, counter that while their designs often create pedestrian and cycling space from areas that were previously occupied by ...


Evidence Supporting Treatment Practice Based Delineation Of Stormwater Runoff Zones, Jacob J. Gorski Oct 2013

Evidence Supporting Treatment Practice Based Delineation Of Stormwater Runoff Zones, Jacob J. Gorski

Dissertations and Theses

Particles mobilized by stormwater negatively affect receiving surface waters. Stormwater best management practices (BMPs) can reduce solids along with associated pollutants in runoff but engineers and environmental managers have been long vexed by the problem of choosing the optimal BMP for a given situation. A common BMP process for solids removal is sedimentation. This thesis addresses the question of whether the effectiveness (and thus choice) of a sedimentation device can be estimated (and thus optimized) from the particle size properties of runoff, which, in turn, could be associated with specific runoff zones or land uses. Presented here is a series ...

Faulty Measurements And Shaky Tools: An Exploration Into Hazus And The Seismic Vulnerabilities Of Portland, Or, Brittany Ann Brannon Aug 2013

Faulty Measurements And Shaky Tools: An Exploration Into Hazus And The Seismic Vulnerabilities Of Portland, Or, Brittany Ann Brannon

Dissertations and Theses

Events or forces of nature with catastrophic consequences, or "natural disasters," have increased in both frequency and force due to climate change and increased urbanization in climate-sensitive areas. To create capacity to face these dangers, an entity must first quantify the threat and translate scientific knowledge on nature into comprehensible estimates of cost and loss. These estimates equip those at risk with knowledge to enact policy, formulate mitigation plans, raise awareness, and promote preparedness in light of potential destruction. Hazards-United States, or Hazus, is one such tool created by the federal government to estimate loss from a variety of threats ...


Neighborhood Commercial Corridor Change: Portland, Oregon 1990-2010, Kelly Ann Howsley-Glover Aug 2013

Neighborhood Commercial Corridor Change: Portland, Oregon 1990-2010, Kelly Ann Howsley-Glover

Dissertations and Theses

Commercial corridors in neighborhoods experiencing change have been relegated to a footnote in research on residential phenomena. It is taken for granted that the process of change experience by businesses within these neighborhoods mirrors that of the residential change. This assumption is often predicated on the underlying model of invasion succession, suggesting that inmovers displace native populations, whether they are residents or businesses. Analyzing time series data on neighborhood commercial corridor change, research attempted to first test data against the invasion succession model to see if it is an effective framework for analysis. Second, through comparison of case study areas ...


Overlooked Destinations: Suburban Nodes, Centers, And Trips To Strips, Nico Larco, Robert Parker Aug 2013

Overlooked Destinations: Suburban Nodes, Centers, And Trips To Strips, Nico Larco, Robert Parker

TREC Final Reports

This study looks at travel to typical suburban commercial strips by residents living within one-third of a mile of the strip by focusing on six sites – four in the Portland, OR., metro area and two in the Atlanta, GA., metro area. The study mapped pedsheds around the commercial strips in these sites and found significant increases in network extents when formal and informal pedestrian paths were added to street centerline data. Informal networks such as goat paths through vacant land and cuts in fences were widespread and suggest a pent-up demand for route directness. Travel surveys of residents found significant ...
