Road Diet V2.0 - Road Diet With Roundabouts, Michael Williams

PSU Transportation Seminars

How can we go one step, or one lane, further than the standard road diet? Roundabouts allow a road diet to reduce the final number of lanes from three to two.

Questions arise when roundabouts are used with a road diet. What traffic volumes are supportable? Will the roundabouts fit within existing intersections? What does current guidance tell us about this approach?

Michael Williams will present his work on creating a sequel to FHWA’s Road Diet Informational Guide. This work is intended to provide a feasibility determination tool for the application of this approach to existing corridors. Data from Bird …

Goodbye To The National Endowment For The Arts?, Naomi Adiv

Urban Studies and Planning Faculty Publications and Presentations

In the shadow of the truly egregious policies rolled out by the Trump administration in their first year in office (anti-Muslim and anti-immigrant policies, de-staffing the State Department into paralysis, shrinking national monuments, strangling the ACA), and a general tone of chaos surrounding the office of the presidency, a standing threat remains. That is: among other cuts, freezes and gag orders, the administration has vowed to defund the National Endowment for the Arts (NEA), National Endowment for the Humanities (NEH) and the Corporation for Public Broadcasting (CPB). Here, I demonstrate how current political arguments around defunding the NEA are derived …

Evaluation Of Route Changes Utilizing High-Resolution Gps Bus Transit Data, Travis Bradley Glick

PSU Transportation Seminars

Congestion and travel delay on urban roadways can influence operating costs and service attractiveness. This research uses high resolution bus data to examine sources of delay on urban arterials. A set of tools was created to help visualize trends in bus behavior and movement; this allowed larger traffic trends to be visualized along urban corridors and urban streets. By using buses as probes and examining aggregated bus behavior, contoured speed plots can be used to understand the behavior of roadways outside the zone of influence of bus stops. Speed plots can be utilized to discover trends and travel patterns with …

Valuing Bicycle Infrastructure In Portland, Oregon, Wei Shi

PSU Transportation Seminars

Investments into active transportation infrastructure are often promoted as a strategy for sustainable transportation, better public health, environmental quality, and economic development. Although empirical evidence generally points toward positive property value impacts of off-street greenways and trails, few focus on whether households might have different willingness-to-pay for different types and levels of bicycle infrastructure. This paper aims to fill research gaps in understanding consumer preferences for different types of bicycle facilities by examining property value impacts of four bicycle facility types: on-street advanced bike facilities and bike lanes; and off-street regional multi-use paths and local multi-use paths. Using Portland, Oregon …

Hedonic Modeling Of Commercial Property Values: Distance Decay From The Links And Nodes Of Rail And Highway Infrastructure, Kihwan Seo, Deborah Salon, Michael Kuby, Aaron Golub

Urban Studies and Planning Faculty Publications and Presentations

This study investigates the impacts of positive and negative externalities of highways and light rail on commercial property values in Phoenix, Arizona. We hypothesize that the positive externality (i.e., accessibility) of highway and light rail accrues at exits and stations, whereas nodes and links of highways and light rail emanate negative effects. Positive and negative effects decay with increasing distance and are captured by multiple distance bands. Hypotheses are tested using a spatial error regression model. Results show that commercial property values are positively and significantly associated with the accessibility benefits of transport nodes. The distance-band coefficients form a typical …

Pipeline To Failure: Social Inequality And The False Promises Of American Public Schooling, Adia Wilson

Dissertations, Theses, and Capstone Projects

My experience as a New York City public school student was absolutely electrifying, though filled with many trials. While my mother would have preferred to put me in private school, having access to some of the world’s greatest institutions and resources offered unique opportunities and exposures. The performing arts provided me with an outlet to express myself and build skills and confidence. In particular, dance education kept me occupied and disciplined in a large city full of danger. Every so often, I witnessed hostile, or even violent exchanges between students, or students and staff. While some of my schoolmates became …

Density Differences: Exploring Built Environment Relationships With Walking Between And Within Metropolitan Areas, Jamie Orrego

PSU Transportation Seminars

Part of the Student Presentations from TRB

To explore the relationships between measures of density and walking within and between urban areas, we present an analysis of the travel survey data from six different cities from the US and Santiago, Chile. The analysis of aggregate and disaggregate pedestrian trips presented here examine the potential consistency of relationships between walking and density within and across different regions, with a specific focus on population density. Our findings illustrate a relationship between population density and walk mode shares that is roughly linear and of nearly equal magnitude across US regions in densities below …

Defining Place: A Review Of How Place Type Is Measured And Constructed, Kelly Rodgers

PSU Transportation Seminars

Part of the Student Presentations from TRB

Researchers have been parsing which components of the built environment contribute to outcomes of interest and to what degree, particularly the effects on vehicle use and walking. Increasingly, researchers and practitioners recognize that the type of neighborhood may affect individual travel behaviors. These bundle of various land use and transportation system characteristics can be constructed as different neighborhood or place types. But not all place types are constructed with the same use, purpose, or methods. This presentation will review three classifications of place typologies to better understand their purpose and appropriate application as …

A survey based on the validated NEMS-S was conducted at each retail food store. …

Exploring The Determinants Of Vulnerable Road Users’ Crash Severity In State Roads, Álvaro Caviedes

PSU Transportation Seminars

Part of the Student Presentations from TRB

Pedestrians and bicyclists are the most vulnerable road users and suffer the most severe consequences when crashes take place. An extensive literature is available for crash severity in terms of driver safety, but fewer studies have explored non-motorized users’ crash severity. Furthermore, most research efforts have examined pedestrian and bicyclist crash severity in urban areas. This study focuses on state roads (mostly outside major urban areas) and aims to identify contributing risk factors of fatal and severe crashes involving pedestrians and bicyclists in state roads. The results seem to suggest that besides improvements …

Development Of A Multi-Modal Travel Demand Module For The Regional Strategic Planning Model, Huajie Yang

PSU Transportation Seminars

Part of the Student Presentations from TRB

Integrated land use and transportation models have evolved along a spectrum with simplistic sketch planning models on one end and sophisticated microsimulation models on the other. While each type of these models has its niche, they are largely unable to balance the flexibility and realism of microsimulation and the speed and interactiveness of simple models. The Regional Strategic Planning Model (RSPM) aims to fill this gap by taking a microsimulation approach but making other simplifications, to model first-order long-term outcomes of land use and transportation quickly. It takes into consideration the underlying uncertainties …

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 …

The Effect Of Localized Density On Housing Prices In Singapore, Eric Fesselmeyer, Kiat Ying Sky Seah, Jonathan Ci Yi Kwok

Research Collection College of Integrative Studies

This paper measures how localized residential density impacts housing prices in Singapore. Using exogenous variation in residential density, we find that an increase in density causes non-trivial decreases in property values: a 10% increase in density decreases price per square foot by between 1.3% and 2%. To the best of our knowledge, ours is the first paper to measure this effect.Further, we find that the negative effect of density is biggest in magnitude for low density apartment projects and the magnitude is decreasing in the density of the project, and that the negative effect of density is increasing in magnitude …

Re-Live Downtown Pine Bluff, Community Design Center

Community Design Center Project Reports

Once a prosperous cultural urban center in the Mississippi River delta, but now the nation’s second fastest shrinking city, Pine Bluff (population: 42,700) is Arkansas’ Detroit. Indeed, a study of black wealth conducted by famed sociologist W. E. B. Du Bois in 1899 found that Pine Bluff had the fourth highest rate of black wealth in the nation behind Charleston, Richmond, and New York City. The school’s community design center prepared a downtown revitalization plan, Re-Live Downtown Pine Bluff, a housing-first initiative focused on building neighborhoods around downtown “centers of strength”. While the revitalization approach is triaged around a …

Center For Farm And Food System Entrepreneurship, Community Design Center

Community Design Center Project Reports

The average age of the American farmer is 58. Since communities are not reproducing the next generation of farmers, universities are establishing training centers to model new concepts and technologies in farming. The Farmers Training Center is both an immersive program in the rhythms of farm life and a public facility for hosting gatherings that celebrate value-added food products. Part of the University of Arkansas’ farm operations near campus, the center is the public face of agriculture where farmers and the public meet. Student farmers learn by farming, from organic vegetable production in fields and greenhouses, to machine repair, marketing, …

New Beginnings Homeless Transition Village, Community Design Center

Community Design Center Project Reports

More than three million Americans experience homelessness annually. Emergency shelter capacity is limited while local governments are unable to provide even temporary housing. Informal housing involving interim self-help solutions are now popular adaptive actions for obtaining shelter despite nonconformance with city codes. Unfortunately, most informal solutions have resulted in objectionable tent cities and squatter campgrounds where the local response has simply been to move the problem around. Our homeless transition village plan prototypes a shelter-first solution using a kit-of-parts that can be replicated in other communities. Village design reconciles key gaps between informal building practices and formal sector regulations, creating …

Willow Heights Livability Improvement Plan, Community Design Center

Community Design Center Project Reports

Willow Heights is a 43-year old public housing complex owned by the Fayetteville Housing Authority (FHA) within the federal public housing portfolio administered by the Department of Housing and Urban Development (HUD). The school’s design center was commissioned by a local foundation to study an alternative to the FHA’s plan to sell the downtown Willow Heights complex to a developer of high-income housing, necessitating relocation of low-income residents to another complex outside of downtown. Using equity as a driver of decision making, the studio introduced scenario planning to organize reluctant stakeholders in considering transformations to the five-acre complex.
