E-Bikes In The United States, John Macarthur

PSU Transportation Seminars

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. Some …

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

Institute of 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.

The Trajectory Of Warwick Junction As A Site Of Inclusivity In Post-Apartheid South Africa, Kara Van Schilfgaarde Van Schilfgaarde

Independent Study Project (ISP) Collection

Warwick Junction, a thriving trading hub in the inner city of Durban, has long been considered one of the best examples of collaborative urban management practices between the local government and informal traders. In a post-apartheid South Africa, there was a national desire to transform the old systems of governance, which in Warwick translated to city government institutions making an effort to include informal traders in the policymaking and management processes. This paper tracks the history of Warwick Junction, using its oppressive past to frame common perspectives of informal trade. It considers the legacy of the post-apartheid era South Africa, …

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

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 automobiles, …

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 the term …

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 …

Well Traveled: Strong Relationships And Unique Challenges Are Revealed In “Driving Richmond: Stories And Portraits Of Grtc Bus Drivers”, Laura Browder

English Faculty Publications

Here’s a well-kept secret: The regional GRTC Transit System is among the most progressive organizations in Richmond. The nonprofit plays a major role in reducing pollution, easing traffic congestion and connecting people to jobs. Its reform-minded leadership is eager to play a larger role. Its unionized bus drivers, which included some of the first waves of black and female drivers, help hold it all together.

And those drivers love their jobs — to a degree unusual for workers in any profession. That’s what I learned through interviews with 16 current and former drivers this summer for an exhibition at the …

Making Time In Boise: Embracing The Befuddling City, Jaap Vos

Urban Studies and Community Development Faculty Publications and Presentations

Boise has a penchant for being listed. In 2011, CNN Money listed Boise as the third-best retirement city. Last year, Forbes ranked Boise as the second-best city in the United States in which to raise a family. In July, the San Francisco Chronicle published an article stating that Boise was the seventh safest city in the U.S. According to the city’s economic development team, since 2008, Boise has made it onto more than 50 top-10 lists. While some of these lists are just plain silly, others are an indication of the qualities that make Boise a remarkable city. And although …

Issue Brief: Auditing Your Town's Development Code For Barriers To Sustainable Water Management, New England Environmental Finance Center

Sustainable Communities Capacity Building

This issue brief is intended for town officials who want to understand how development regulations in their community affect local water resources. Municipal development codes – the set of regulations that control the built environment – can have a great influence on the availability of clean and healthy water for drinking, recreation, and commercial uses. This in turn affects the community’s social, environmental, and economic vitality.

Comprehensive plans, zoning codes, and building standards are just a few examples of regulations that intentionally or unintentionally regulate the way water is transported, collected and absorbed. Regulations that produce dispersed development or large …

Modeling Of Dc Link Capacitor Current Ripple For Electric Vehicle Traction Converter, Lei Jin, Julia Zhang

TREC Final Reports

Contemporary Full Hybrid Electric Vehicle/Plug-in Hybrid Electric Vehicle/Battery Electric Vehicle (FHEV/PHEV/BEV) products use one or more DC/AC power converters, also known as traction inverters, to convert the DC voltage/current provided by the traction battery to the AC voltage/current to drive the traction motor(s). Large and bulky DC link capacitors are used at the input of the traction inverter to provide a smooth DC input voltage. Those DC link capacitors, occupying almost 50% of the space in the whole package, can contribute to more than 20% of the total cost of the traction inverter. They are generally over designed to assure …

The Mayaarch3d Project: A 3d Webgis For Analyzing Ancient Architecture And Landscapes, Jennifer Von Schwerin, Heather Richards-Rissetto, Fabio Remondino, Giorgio Agugario, Gabrio Girardi

Department of Anthropology: Faculty Publications

There is a need in the humanities for a 3D WebGIS with analytical tools that allow researchers to analyze 3D models linked to spatially referenced data. Geographic Information Systems (GIS) allow for complex spatial analysis of 2.5D data. For example, they offer bird’s eye views of landscapes with extruded building footprints, but one cannot ‘get on the ground’ and interact with true 3D models from a pedestrian perspective. Meanwhile, 3D models and virtual environments visualize data in 3D space, but analytical tools are simple rotation or lighting effects. The MayaArch3D Project is developing a 3D WebGIS—called QueryArch3D—to allow these two …

Civil and Environmental Engineering Faculty Publications and Presentations

There is growing support for improvements to the quality of the walking environment, including more investments to promote pedestrian travel. Metropolitan planning organizations (MPOs) are improving regional travel demand forecasting models to better represent walking and bicycling and to expand the evaluative capacity of models to address policy-relevant issues like air quality, public health, and the smart allocation of infrastructure and other resources. This report describes an innovative, spatially disaggregate method to integrate walking activity into trip-based travel models. Using data for the Portland, OR, metropolitan area, the method applies trip generation at a new micro-scale spatial unit: a 264-foot-by-264-foot …

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, …

Ohio Utica Shale Gas Monitor, Edward W. Hill, Kelly Kinahan

All Maxine Goodman Levin School of Urban Affairs Publications

Development of the Utica Shale is impacting the economy of nearly every one of Ohio’s 88 counties. Although still in the exploration phase, the Utica Shale is triggering wealth creation even as the ongoing build-out of the formation’s midstream of pipelines and processing plants is limiting job creation and productivity.

This quarterly study groups Ohio’s counties into four categories: strong shale, moderate shale, weak shale, and non-shale counties. The results show that strong shale counties are experiencing ongoing enhanced economic activity with job creation that, while slim, outpaces hiring in other areas of the state. This wealth and job creation …
