Three Essays On Understanding Municipal Water Demand In The Western United States, Michael J. O'Donnell

Economics ETDs

Scarce water resources in the Western United States, in concert with population growth and climate change, constitute a need to better understand factors that impact water demand. In this dissertation, Chapter 1 provides cultural and historical context for water use in the West and argues that understanding water demand is important, especially when managing scarcity is a goal. Chapter 2 uses aggregate city-level data from four municipalities in New Mexico to investigate seasonal trends and breakpoints. Although per premises and aggregate demand tend to decline in all geographies investigated, existence and timing of breakpoints varies by geography. Additionally, drivers of …

Transportation Impacts Of Affordable Housing: Informing Development Review With Travel Behavior Analysis, Amanda Howell

PSU Transportation Seminars

Planning for affordable housing is challenged by development policies that often do not differentiate between the travel patterns of residents of market-rate housing and those living in affordable units. The development review process generally requires an evaluation of the anticipated additional transportation demand that new development places on the system and an assessment of fees or improvements to mitigate these impacts.

However, industry standard guidelines for assessment of travel demand outlined within the Institute of Transportation Engineers (ITE) Trip Generation Handbook have been focused solely on vehicle trip rates for these traffic impact analyses. Given the public goals of providing …

Land-Use And Land-Ownership Changes In Usoma Village, Kenya, Ernest Tan

Independent Study Project (ISP) Collection

This study attempted to find out how land-use activities and land-ownership patterns have changed since land adjudication in Usoma Village, a peri-urban community on the fringe of Kisumu City. The methods used were photo-observation and geo-tagging based on walkabouts onsite, documentary analysis of maps obtained from the Ministry of Lands, interviews with key authority figures, independent experts and community leaders, and interviews as well as focus-group discussions with community members. In terms of land ownership, it was found that subdivisions of land, both formal and informal, had been common over the period. Land transfers based on compulsory acquisition and investment …

Project Phenom: A Smart Bike Project, Stephen Fickas

TREC Final Reports

This project introduces students to hands-on, experience-building, smart-transportation hardware and software. After completing the project, students will gain practical experience with integrating a set of inexpensive, commercial computer components to deliver a ready-to-install system that can extend the transportation grid of a city.

Addressing Bicycle-Vehicle Conflicts With Alternate Signal Control Strategies, Sirisha Kothuri, Andrew Kading, Andrew Schrope, Kelly White, Edward Smaglik, Chris Aguilar, William Gil

TREC Final Reports

Over the last decade there has been increased interest in promoting active and sustainable transportation modes such as bicycling and walking especially in urban areas, as a means to alleviate congestion, lower emission levels and improve personal health. In urban areas, intersections are locations where a variety of modes converge, thus increasing the propensity for conflicts. Many bicycle-vehicle crashes occur at intersections. A common crash type involving bicycles at intersections is the “right-hook” where a right-turning vehicle collides with a through bicyclist. Intersections are also the source of increased stress for many bicyclists where the interactions with cars are more …

Overcoming Barriers For The Wide-Scale Adoption Of Standardized Real-Time Transit Information, Sean J. Barbeau

TREC Final Reports

In the last few years, a real-time counterpart to GTFS, GTFS-realtime [10], has begun to emerge, with agencies sharing their real-time data in this format. Previously, real-time transit information had only been shared in proprietary formats specific to each vendor or agency. GTFS-realtime offers the opportunity for application developers to create a mobile app that can function across a large number of cities and agencies, and for practitioners and researchers to be able to easily study and compare actual system performance across different transit systems using the same tools, without the overhead of manually transforming data into a consistent format. …

The Contribution Of Transportation And Land Use To Citizen Perceptions Of Livability In Oregon Mpos, Rebecca Lewis, Robert Parker

TREC Final Reports

What is livability? How does the built environment influence resident perceptions of livability? Although livability is a broadly used term and a key goal in land use and transportation plans at the state level, it is unclear whether residents think their neighborhoods are livable and what contributes to their perception of livability. The purpose of this project was to understand how Oregonians, in neighborhoods of varying densities and within Metropolitan Planning Organizations (MPOs), perceive livability at the nexus of transportation and land use. We sought to understand how residents define and perceive livability in three different MPOs in the state: …

Urban Geocomputation: Two Studies On Urban Form And Its Role In Altering Climate, Jackson Lee Voelkel

Our climate and our cities are changing. Though their changes are not completely dependent upon one another, there is still a coupling effect between them. This study assesses the role of urban form as it pertains to elements of climate change. It is comprised of two essays intended for publication. The first of these essays addresses the feedbacks between urban form, energy consumption, and rising global temperatures. The second essay looks at one particular factor of urban form--tree type--as it pertains to air pollution and urban heat island mitigation. Both papers use the analytical approaches necessary to answer the questions …

Undimmed By Human Tears: American Cities, Philanthropy, And The Civic Ideal (1992), Marcy Murninghan

New England Journal of Public Policy

Commissioned by the Council on Foundations in 1992 at a time when urban concerns had fallen off the national agenda, this article contains summary recommendations of an investigation into the response of grantmakers and urban policy experts after the deadly violence that occurred in Los Angeles that spring. An April 29 state-court acquittal of police officers accused of using excessive force against Rodney King had sparked two days of burning and looting throughout South Central Los Angeles, an area hard-hit by job loss and plant closings that over the previous twenty years had become demographically and economically transformed. Once an …

This article includes portions of a report on the structure, governance, operations, and effectiveness of the Boston School Committee that was commissioned by the Boston Municipal Research Bureau in 1980. The passages provide an overview of the mandate, background, and recommendations, examining how a set of prominent professionals and citizens viewed the problem facing school department governance, including its isolation and the longstanding credibility gap fueled by patronage politics. It also looks at continued tensions between “equality” and “quality,” which occupied the heart of court-ordered desegregation; rising demands on a system that lacked the capacity to serve a broad array …

Getting Power Back: Court Restoration Of Executive Authority In Boston City Government (1985), Marcy Murninghan

New England Journal of Public Policy

This article, originally published in 1985, is based partly on the author’s experience with the Boston school desegregation case, but goes beyond it. It chronicles some of the events that occurred when a state and a federal court attempted to disengage from active jurisdiction over two Boston public systems: the Boston Public Schools and the Boston Housing Authority. It makes three proposals, which, if enacted, would help to keep the courts out of day-to-day management of municipal operations. It also makes some generalizations about the court-agency interplay that are relevant to the post-remedial phase of institutional reform litigation. The author …

Insights On Walkability And Walking In Lisbon With The Iaape Method, Filipe Moura

PSU Transportation Seminars

Walkability and walking are being intensively researched today and the literature provides a wealth of references and examples on how to measure walkability of the built environment. IAAPE is one method that was developed at the Instituto Superior Técnico (Lisbon) to measure walkability at the micro-scale, bringing solutions that were disregarded in two aspects: it is a participatory process; and it provides different evaluations for different population segments (adults, children, seniors, impaired) or for different trip motivations.

Transit Demand Analysis And User Classification Using Automatic Fare Collection (Afc) Data, Alireza Khani

PSU Transportation Seminars

Development of origin-destination demand matrices is crucial for transit planning. The development process is facilitated by transit automated data, making it possible to mine boarding and alighting patterns on an individual basis. This research proposes a novel stochastic trip chaining method which uses Automatic Fare Collection (AFC) and General Transit Feed Specifications (GTFS) data to infer an origin-destination (O-D) matrix.

Citizen Advocacy For Safe Streets In Bremen, Germany, Anne Kirkham

PSU Transportation Seminars

Although Germany may be known internationally for its environmentalism, over the past 20 years German cities have chronically underinvested in transportation networks, both for public transport as well as non-motorized options. The lag in the development and expansion of sustainable options combined with the rapid growth in private automobile ownership (itself the result of automobile-industry-friendly policymaking) means that cities like Bremen have been left behind in terms of transportation planning. As in America, SUV sales continue to increase despite considerably narrower streets, particularly in cities.

Nowhere is this more visible than in Bremen’s Neustadt, a dense neighbourhood with the most …

Recent Advances In Activity-Based Travel Demand Models For Greater Flexibility, Kihong Kim

Dissertations and Theses

Most existing activity-based travel demand models are implemented in a tour-based microsimulation framework. Due to the significant computational and data storage benefits, the demand microsimulation allows a greater amount of flexibility in terms of demographic market segmentation, temporal scale, and spatial resolution, and thus the models can represent a wider range of travel behavior aspects associated with various policies and scenarios. This dissertation proposes three innovative methodologies, one for each of the three key dimensions, to fulfill the greater level of details toward a more mature state of activity-based travel demand models.

Transitory Ownership: A Spatial Analysis Of The Financialization Of The Housing Market In Cincinnati, Oh, Chad Kinsella, Colleen Mctague, Rafael Ranieri

The Journal of Economics and Politics

The mortgage bubble that burst in 2007 created an economic environment where many housing properties were transferred from individual households to investors hoping for quick profits with minimal investment. These properties were traded among investors, businesses, and lenders; they acquired a market identity as financial assets; and many of these properties were acquired by “out-of-area” interests. This study examines properties purchased by out-of-area interests that were sold in 2009 within the City of Cincinnati in an attempt to identify the spatial implications of the financialization of this housing stock. The analysis finds that many of these properties were sold multiple …

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 …
