Transportation System Impacts On Bicyclists' Air Pollution Risks: Considerations For System Design And Use, Alexander Y. Bigazzi, Miguel Figliozzi, James F. Pankow, Wentai Luo Feb 2015

Transportation System Impacts On Bicyclists' Air Pollution Risks: Considerations For System Design And Use, Alexander Y. Bigazzi, Miguel Figliozzi, James F. Pankow, Wentai Luo

PSU Transportation Seminars

Health risks associated with air pollution uptake while bicycling are often cited as a potential drawback to increased bicycling in cities. This seminar will provide an overview of how roadway and travel characteristics impact bicyclists' uptake of traffic-related air pollution. Specific considerations for planners and designers of urban transportation systems to mitigate risks for travelers will be discussed. In addition, the extent to which bicyclists themselves can unilaterally reduce their pollution uptake will be described. This seminar synthesizes findings from a recently completed doctoral dissertation at Portland State University and from the broader literature.


The Theory Of Travel Decision-Making: A Conceptual Framework Of Active Travel Behavior, Patrick Allen Singleton Jan 2015

The Theory Of Travel Decision-Making: A Conceptual Framework Of Active Travel Behavior, Patrick Allen Singleton

PSU Transportation Seminars

We present a unifying conceptual framework of active travel behavior called the theory of travel decision-making. It integrates seminal travel-related concepts from economics, geography, and psychology with active travel behavior theories and empirical research. The framework abstracts an individual’s thought process around short-term travel decisions and explains the roles of activities, built environment factors, socio-demographics, attitudes and perceptions, and habit. Our primary objective is to inform travel behavior research by meeting the need for a theoretical framework capable of guiding studies on active transportation. The framework could also support active transportation planning and analysis methods by informing the development of …


Factors Associated With The Bicycle Commute Use Of Newcomers: Analysis Of The 70 Largest U.S. Cities, Ryan Dann Jan 2015

Factors Associated With The Bicycle Commute Use Of Newcomers: Analysis Of The 70 Largest U.S. Cities, Ryan Dann

PSU Transportation Seminars

Bicycling is known to produce benefits for cities, in regards to reducing levels of congestion, generating positive health outcomes, and providing affordable transportation options to low-income families. Conventional analysis of urban bicycle commuting does not currently consider the importance of separating migrant, or “newcomer,” bicycle commute use from pre-existing resident bicycle commute use. The goal of this paper is to provide additional information on individual, social, and environmental factors that influence newcomer bicycle use for commuting purposes. This cross-sectional study used data from the 2007-2011 American Community Survey (5-year Estimates) to analyze the bicycle commute use of newcomers in the …


Who Uses Peer-To-Peer Carsharing? Early Exploration, Anaïs Mathez Jan 2015

Who Uses Peer-To-Peer Carsharing? Early Exploration, Anaïs Mathez

PSU Transportation Seminars

Peer-to-peer (P2P) carsharing is a system where a facilitating company connects car owners to car renters. Such systems are relatively new in the U.S. This paper aims to understand who is participating in P2P carsharing as a renter (as opposed to as an owner), why they join, whether and how often they rent vehicles, and why. Exploring these questions may provide insight on the potential for P2P carsharing to meet public policy objectives of reducing the impacts of personal vehicle ownership and use and providing mobility options for underserved populations. The analysis is based on 465 study participants who enrolled …


Leveraging Signal Infrastructure For Non-Motorized Counts In A Statewide Program: A Pilot Study, Bryan Philip Blanc Jan 2015

Leveraging Signal Infrastructure For Non-Motorized Counts In A Statewide Program: A Pilot Study, Bryan Philip Blanc

PSU Transportation Seminars

Transportation agencies are beginning to explore and develop non-motorized counting programs. This paper presents the results of a pilot study testing the use of existing signal infrastructure – 2070 signal controllers with advanced software to log pedestrian phase actuations and detections from bicycle lane inductive loops – to count pedestrians and bicycles. The pilot study was conducted at a typical suburban signalized intersection with heavy motorized traffic that was instrumented on all four approaches with pedestrian push buttons and advance inductive loops in the bicycle lane for signal operation. One day (24 hours) of video data were collected as ground …


Influential Vectors In Fuel Consumption By An Urban Bus Operator, João De Abreu E Silva Jan 2015

Influential Vectors In Fuel Consumption By An Urban Bus Operator, João De Abreu E Silva

PSU Transportation Seminars

In an era of reduced government funding, transit operators struggle to reduce operating costs and increase revenues. Energy costs account for an important share of the total costs of urban and suburban bus operators. Using a case study of one operator in Lisbon, Portugal, this talk will expand upon the empirical research on bus transit operation costs and identify the key factors that influence the energy efficiency of the overall bus fleet. Our results of a multivariate analysis find the following dimensions influence transit energy efficiency: vehicle type, commercial speed, road grades and bus routes; and to a lesser extent …


The Political Correlates Of Sustainable Development: A Case Study Of Winter Park, Fl, Ariella Lvov Jan 2015

The Political Correlates Of Sustainable Development: A Case Study Of Winter Park, Fl, Ariella Lvov

Honors Program Theses

How do cities find the path to sustainable development policy when confronted with constituent opposition? To address this dilemma, a case study of a small, land-locked city in Central Florida was conducted, whose long battle with sustainable development has been, at times, both successful and unsuccessful. Winter Park provides an excellent backdrop for studying which political correlates are requisite for the successful execution of growth policy. This study explores three sustainable development initiatives in Winter Park: (a) light rail, (b) SunRail, and (c) transit-oriented development. The researcher conducted an analysis of both archival research and structured interviews with local elected …


Transit And Economic Resilience, Arthur C. Nelson, Matt Miller, Joanna P. Ganning, Philip Stoker, Jenny H. Liu, Reid Ewing Jan 2015

Transit And Economic Resilience, Arthur C. Nelson, Matt Miller, Joanna P. Ganning, Philip Stoker, Jenny H. Liu, Reid Ewing

Urban Studies and Planning Faculty Publications and Presentations

Do fixed-guideway transit systems facilitate resilience with metropolitan areas? There is little literature making this connection theoretically and none testing it empirically. This paper helps close this gap in both respects. In evaluating metropolitan areas with light rail transit systems the authors find evidence that transit corridors on the whole performed better than control corridors during the recovery period of two recessions: that of the early 2000s and the so-called Great Recession. In particular, during the Great Recession transit corridors outperformed control corridors among many economic sectors. Outcomes were more impressive during recoveries from both the recession of the early …


Office Rent Premiums With Respect To Distance From Light Rail Transit Stations In Dallas And Denver, Arthur C. Nelson, Dejan Eskic, Joanna P. Ganning, Shima Hamidi, Susan J. Petheram, Jenny H. Liu, Reid Ewing Jan 2015

Office Rent Premiums With Respect To Distance From Light Rail Transit Stations In Dallas And Denver, Arthur C. Nelson, Dejan Eskic, Joanna P. Ganning, Shima Hamidi, Susan J. Petheram, Jenny H. Liu, Reid Ewing

Urban Studies and Planning Faculty Publications and Presentations

It seems an article-of-faith that real estate markets respond more favorably to location within one-half mile of transit stations. Planning and public decision-makers have thus drawn half-mile (or smaller) circles around rail transit stations assuming larger planning areas would not be supported by the evidence. Recent research, however, has shown market-responsiveness well beyond one-half mile. We contribute to this literature by evaluating the distance-decay function of office rents in metropolitan Dallas and Denver with respect to light rail transit (LRT) station distance. Using a quadratic transformation of distance we find office rent premiums extending in the range of two miles …


Commuter Rail Transit And Economic Development, Arthur C. Nelson, Matt Miller, Keuntae Kim, Joanna P. Ganning, Jenny H. Liu, Reid Ewing Jan 2015

Commuter Rail Transit And Economic Development, Arthur C. Nelson, Matt Miller, Keuntae Kim, Joanna P. Ganning, Jenny H. Liu, Reid Ewing

Urban Studies and Planning Faculty Publications and Presentations

Commuter rail transit (CRT) is a form of rail passenger service connecting downtowns and other major activity centers with suburban commuter towns and beyond. Between 1834 and 1973, only three public CRT systems were built in the U.S. serving New York, Chicago and then Boston. There are now 25 such systems. Modern CRT systems aim to expand economic development in metropolitan areas. But do they? This paper evaluates the economic development performance of five modern CRT systems. The authors find that several economic sectors perform well within 0.50 miles of CRT stations. The authors offer planning and policy implications.


Comparing Two Common Approaches To Public Transit Service Equity Evaluation, Alex Karner, Aaron Golub Jan 2015

Comparing Two Common Approaches To Public Transit Service Equity Evaluation, Alex Karner, Aaron Golub

Urban Studies and Planning Faculty Publications and Presentations

Understanding the equity effects of transit service changes requires good information about the demographics of transit ridership. Both on-board survey data and census data can be used to estimate equity effects, though there is no clear reason these two sources will result in the same finding of impact. Guidance from the Federal Transit Administration (FTA) recommends using either of these data sources to estimate equity impacts. This article makes a direct comparison of the two methods for the public transit system in the Phoenix, Arizona metropolitan area. The results indicate that, although both sources are acceptable for FTA compliance, the …


But Do Lower-Wage Jobs Follow? Comparing Wage-Based Outcomes Of Light Rail Transit To Control Corridors, Arthur C. Nelson, Matt Miller, Dejan Eskic, Joanna P. Ganning, Jenny H. Liu, Reid Ewing Jan 2015

But Do Lower-Wage Jobs Follow? Comparing Wage-Based Outcomes Of Light Rail Transit To Control Corridors, Arthur C. Nelson, Matt Miller, Dejan Eskic, Joanna P. Ganning, Jenny H. Liu, Reid Ewing

Urban Studies and Planning Faculty Publications and Presentations

Literature suggests that rail transit improvements should be associated with more jobs and perhaps increasing share of jobs in a metropolitan area. Literature and some research also suggest that such improvements should increase the number of lower-wage jobs accessible to transit. In this paper, we assess both in the context of all 11 light rail transit systems built in metropolitan areas of fewer than eight million residents in the nation since 1981. Using census block-level job data over the period 2002 to 2011, we evaluate change in jobs and change in metropolitan area job share for all jobs, and lower- …


Retail Rent With Respect To Distance From Light Rail Transit Stations In Dallas And Denver, Arthur C. Nelson, Dejan Eskic, Joanna P. Ganning, Shima Hamidi, Susan J. Petheram, Jenny H. Liu, Reid Ewing Jan 2015

Retail Rent With Respect To Distance From Light Rail Transit Stations In Dallas And Denver, Arthur C. Nelson, Dejan Eskic, Joanna P. Ganning, Shima Hamidi, Susan J. Petheram, Jenny H. Liu, Reid Ewing

Urban Studies and Planning Faculty Publications and Presentations

A growing body of recent research is challenging the assumptions underlying the half-mile-circle in planning for development around transit stations. In this article we review this literature and extend it to include retail land uses. We estimate the rent premium conferred on retail properties in metropolitan Dallas and metropolitan Denver, both of which have extensive light rail transit systems. We find that consistent with half-mile-circle assumptions, retail rent premiums extend only to about 0.30 mile from transit stations with half the premium dissipating after a few hundred feet and three quarters within the first 0.10 mile. We offer implications for …

Urban Studies and Planning Faculty Publications and Presentations

This workshop discussed various aspect of the mathematical part of survey methodology, as well as archiving and confidentiality issues aimed at improving data quality and its use through time. Participants identified ways to correct or minimize bias by dealing with incomplete sampling frames, using weighing and imputing procedures. We discussed methods to archive and share GPS-based survey data to preserve anonymity. Finally, we debated research needs on these topics for the next following years.


Feasibility Analysis And Strategic Measures For Promoting Viable New Urban Development, Elizabeth J. Farr Jan 2015

Feasibility Analysis And Strategic Measures For Promoting Viable New Urban Development, Elizabeth J. Farr

CMC Senior Theses

This thesis demonstrates that New Urbanism is both an advisable and feasible method for reducing carbon emissions to mitigate global climate change. New Urban areas commonly generate lower carbon emissions compared to conventional suburban development due to lower car use and higher levels of walking and use of other forms of transportation. Economic and political feasibility of New Urban development is determined by analyzing case studies, housing price premia, financing, and fiscal impact. The many contexts and perspectives involved in the planning process are analyzed to determine if New Urbanism is advisable in the larger setting in which developers, advocates, …


Evaluating The Planning And Implementation Of Major Transit Capital Projects In The Portland Region, Joseph Recker Dec 2014

Evaluating The Planning And Implementation Of Major Transit Capital Projects In The Portland Region, Joseph Recker

PSU Transportation Seminars

The Federal Transit Administration's (FTA) discretionary New Starts program is the federal government's largest discretionary funding program. From heavy to light rail, from commuter rail to bus rapid transit systems, the FTA's New Starts program has helped to make possible hundreds of new or extended transit fixed guideway systems across the country, including most of TriMet’s light rail extensions and WES commuter rail. Beginning in 2001, FTA has required project sponsors to prepare a Before and After Study report on the effectiveness of planning and implementation of New Starts and Small Starts projects. The studies focus on five transit characteristics …

Associations Between Travel Behavior And The Academic Performance Of University Students, Qianying Wu Dec 2014

Associations Between Travel Behavior And The Academic Performance Of University Students, Qianying Wu

All Theses

Purpose: Different travel behavior, particularly the choice of commuting modes, will have different impacts on students. On one hand, it has been suggested that active commuting (walking, cycling, and taking transit) will add routine daily exercise. Moreover, health benefits (improved cognitive function and reduced anxiety) from physical activity might increase students' academic performance. Nevertheless, too much physical activity may reduce the time for students to study. Travel time may shorten study time, and study time has been identified as positively contributing to academic performance. Considering that there is limited research examining travel behavior and academic achievement of university students, this …

Developing Seamless Connections In The Urban Transit Network: A Look Toward High-Speed Rail Interconnectivity, Tingting Yu Dec 2014

Developing Seamless Connections In The Urban Transit Network: A Look Toward High-Speed Rail Interconnectivity, Tingting Yu

UNLV Theses, Dissertations, Professional Papers, and Capstones

In the past, the studies in the U.S. on high speed rail have been on economic impact. Recently, there are a few studies on the multimodal connectivity at high speed rail stations. High speed rail stations are viewed as hubs that are connected by different modes of public transportation by which passengers are transported to their destinations. How and in which way these different modes are connected to high speed rail stations influence the ridership of high speed rail stations. As the development of high speed rail system in the U.S. has come to the stage for actual design and …


Evaluating The Level-Of-Service Of Protected Bike Lanes, Nick Foster Nov 2014

Evaluating The Level-Of-Service Of Protected Bike Lanes, Nick Foster

PSU Transportation Seminars

Summary: The most recent edition of the Highway Capacity Manual (HCM) contains analysis procedures for measuring the level-of-service (LOS), also referred to as quality of service, provided by an urban roadway to bicyclists. The method uses different design and operating features of the roadway segment (e.g. width, motor vehicle volumes and speeds) to assess an LOS grade of A (best) to F (worst). These procedures are used by planners and engineers to recommend how existing streets could be retrofitted or new streets designed to better serve people on bicycles (and other modes). However, the current HCM does not include methods …

Trick Or Treat(Ment)? : Impact Of Route-Level Features On Walk And Bike Decisions, Joseph Broach Oct 2014

Trick Or Treat(Ment)? : Impact Of Route-Level Features On Walk And Bike Decisions, Joseph Broach

PSU Transportation Seminars

Trick or Treatment? Impact of Route-Level Features on Decisions to Walk or Bike Summary: Some travel routes attract people walking and cycling, while others may scare them away. What features of street environments are most important, and how do available routes affect decisions to bike or walk on a specific trip?

Research to date has focused on either large-scale areal measures like "miles of bike lane nearby" or else has considered only shortest path routes. Neither method is suited to capturing the impact of targeted route-level policies like neighborhood greenways. This session will present a new technique for measuring bike …

Development Of The Idaho Statewide Travel Demand Model Trip Matrices Using Cell Phone Od Data And Origin Destination Matrix Estimation, Ben Stabler

PSU Transportation Seminars

As part of the initial phase of development for the Idaho Statewide Travel Demand Model, Parsons Brinckerhoff developed a base year auto and truck trip matrix using AirSage cell phone OD data, a statewide network in Cube, traffic counts, and origin-destination matrix estimation (ODME) procedures. To begin, the 4000+ statewide zone system was aggregated into a 700 super zone system for collecting the cell phone OD data. Next, the cell phone data was collected for the month of September 2013 for the following market segments: Average weekday resident HBW, HBO, NHB, and visitor NHB trips. The cell phone trips were …


Examining The Role Of Internal Planning Decisions In Improving Transit Performance And Economic Outcomes, Michal Jaroszynski Oct 2014

Examining The Role Of Internal Planning Decisions In Improving Transit Performance And Economic Outcomes, Michal Jaroszynski

PSU Transportation Seminars

Scholars and practitioners continuously seek best practices to increase transit ridership, efficiency, and modal share. The ongoing suburbanization and decentralization of U.S. metropolitan regions brings new challenges for accomplishing these goals. Investigating possible strategies for improving transit outcomes in the existing socioeconomic setting, scholars from the Florida State University have pointed to the role of internal performance factors. In a series of research studies, they have found that improving transit service characteristics, such as frequency, connectivity, regional coverage, intermodal integration, as well as decentralization of network structures, could result in increased transit ridership and productivity. These positive effects could be …


Using "Big Data" For Transportation Analysis: A Case Study Of The La Metro Expo Line, Mohja L. Rhoads Oct 2014

Using "Big Data" For Transportation Analysis: A Case Study Of The La Metro Expo Line, Mohja L. Rhoads

PSU Transportation Seminars

Access to a comprehensive historical archive of real-time, multi-modal multi-agency transportation system data has provided a unique opportunity to demonstrate how “big data” can be used for policy analysis, and to offer new insights for planning scholarship and practice. We illustrate with a case study of a new rail transit line. We use transit, freeway, and arterial data of high spatial and temporal resolution to examine transportation system performance impacts of the Exposition (Expo) light rail line (Phase 1) in Los Angeles. Using a quasi-experimental research design, we explore whether the Expo Line has had a significant impact on transit …


Go Before You Go: How Public Toilets Impact Public Transit Usage, Kate M. Washington Oct 2014

Go Before You Go: How Public Toilets Impact Public Transit Usage, Kate M. Washington

PSU McNair Scholars Online Journal

The emphasis on sustainable solutions in Portland, Oregon includes developing multi-modal transportation methods. Using public transit means giving up a certain amount of control over one’s schedule and taking on a great deal of uncertainty when it comes to personal hygiene. Buses, the MAX, and the Streetcar – the cornerstones of public transit in Portland – are not equipped with toilets and rarely are their stations, while most shops and restaurants reserve toilets for patrons only. As a result, many people may bypass public transit in favor of cars, which afford travelers greater autonomy and flexibility. Theories of New Urbanism …


Regulations Of E-Bikes In North America, John Macarthur, Nicholas Kobel Aug 2014

Regulations Of E-Bikes In North America, John Macarthur, Nicholas Kobel

TREC Final Reports

Throughout the world, the electric bicycle (e-bike) industry is growing very quickly. The North American market has been somewhat slow to adopt this technology, which is still considered to be in the “early adopter” phase (Rose & Dill, 2011; Rose, 2011), but in recent years, this has begun to change. But as e-bike numbers increase, so too will potential conflicts (actual or perceived) with other vehicles and non-motorized devices, bicycles and pedestrians, causing policy questions to arise. Indeed, conflicting user groups are petitioning state legislatures and local governments for permission to operate legally on roadways and paths or to ban …


Assessing Transit Fare Equity In Utah Using A Geographic Information System, Steven Farber, Keith Batholomew, Xiao Li, Antonio Paez, Khandker M. Nurul Habib Jul 2014

Assessing Transit Fare Equity In Utah Using A Geographic Information System, Steven Farber, Keith Batholomew, Xiao Li, Antonio Paez, Khandker M. Nurul Habib

TREC Final Reports

The goal of this study is to develop and apply a new method for assessing social equity impacts of distance-based public transit fares. Shifting to a distance-based fare structure can disproportionately favor or penalize different subgroups of a population based on variations in settlement patterns, travel needs, and most importantly, transit use. According to federal law, such disparities must be evaluated by the transit agency, but the area-based techniques identified by the Federal Transit Authority for assessing discrimination fail to account for disparities in distances travelled by transit users. This means that transit agencies currently lack guidelines for assessing the …


Accessibility-Based Transportation Planning: Literature And Applications For Shrinking Cities, Joanna Ganning Jul 2014

Accessibility-Based Transportation Planning: Literature And Applications For Shrinking Cities, Joanna Ganning

TREC Final Reports

For 15 years, scholars have claimed that accessibility-based transportation planning was at the brink of becoming a new paradigm, and yet this hope remains unrealized. Its implementation may lag due to vague definitions when compared to mobility, or because those who would benefit from accessibility-based planning lack political power to rally its support. Possibly, the lag in implementation reflects the missing linkages between theory and application for many contexts. This literature review synthesizes knowledge regarding the applications for accessibility-based transportation planning for shrinking cities along the themes of environmental, social, and economic sustainability. While residents in shrinking cities might especially …
