Webinar: Breaking Barriers To Bike Share: Insights On Equity, Nathan McNeil, Jennifer Dill, John MacArthur 2017 Portland State University

Webinar: Breaking Barriers To Bike Share: Insights On Equity, Nathan Mcneil, Jennifer Dill, John Macarthur

TREC Webinar Series

While the number of public bike share systems in the United States grew considerably in recent years, early evidence indicated that many systems were not serving the diverse populations of cities, particularly lower-income residents and people of color. Lack of bike share stations in neighborhoods with people of color and/or lower incomes is one factor; however, considerable disparities appear to persist even when stations are placed in these communities.

Efforts to overcome access and use barriers (such as cost, payment options, and familiarity with the system) to bike share for underserved communities have been initiated in a number of ...


Benefit-Cost Analysis For Transportation Planning And Public Policy: Towards Multimodal Demand Modeling, Matthew Holian, Ralph McLaughlin 2017 San Jose State University

Benefit-Cost Analysis For Transportation Planning And Public Policy: Towards Multimodal Demand Modeling, Matthew Holian, Ralph Mclaughlin

Matthew J. Holian

This report examines existing methods of benefit-cost analysis (BCA) in two areas, transportation policy and transportation planning, and suggests ways of modifying these methods to account for travel within a multimodal system. Although the planning and policy contexts differ substantially, this report shows how important multimodal impacts can be incorporated into both by using basic econometric techniques and even simpler rule-of-thumb methods. Case studies in transportation planning focus on the California Department of Transportation (Caltrans), but benchmark California’s competencies by exploring methods used by other states and local governments. The report concludes with a list and discussion of recommendations ...


California Voting And Suburbanization Patterns: Implications For Transit Policy, Mti Report 12-05, Matthew J. Holian, Matthew E. Kahn 2017 San Jose State University

California Voting And Suburbanization Patterns: Implications For Transit Policy, Mti Report 12-05, Matthew J. Holian, Matthew E. Kahn

Matthew J. Holian

Public transit is an environmentally friendly transportation mode that usually focuses on transporting people within and to the city center. However, over the last 60 years, population and employment has been suburbanizing. As the median voter lives further from the city center, and thus enjoys fewer benefits from accessing public transit, does this reduce such a voter’s propensity to support public investment in public transit improvements? We analyze voting patterns on 20 transit-related ballot propositions from state-wide elections in California between 1990 and 2010. Controlling for demographic, socio-economic and political ideological factors, we focus on the role of suburbanization ...


The Impact Of Center City Economic And Cultural Vibrancy On Greenhouse Gas Emissions From Transportation, Research Report 11-13, Matthew J. Holian, Matthew E. Kahn 2017 San Jose State University

The Impact Of Center City Economic And Cultural Vibrancy On Greenhouse Gas Emissions From Transportation, Research Report 11-13, Matthew J. Holian, Matthew E. Kahn

Matthew J. Holian

Urban planners and scholars have focused a great deal of attention on understanding the relationship between the built environment and transportation behavior. However, other aspects of the urban environment – including the vibrancy and quality of life in urban areas – have received little attention. This report seeks to close this gap by analyzing the effects of both land-use and urban vibrancy on transportation patterns. Analysis of data from a variety of sources suggests that in addition to the built-environment, the vibrancy of the urban environment also affects transportation behavior. Moreover, vibrancy affects land-use patterns. By integrating objective measures of center-city quality ...


Talking The Walk: An Autoethnography Of Pedestrianism In Chicagoland, Andrew Kuka 2017 Illinois State University

Talking The Walk: An Autoethnography Of Pedestrianism In Chicagoland, Andrew Kuka

Stevenson Center for Community and Economic Development

This autoethnographic account of pedestrianism in Chicagoland aims to remind us of the sensory, social, and emotional experiences walking can provide, and how an environment centered around automobiles affects those experiences. It utilizes participant observations and refers to literature from a wide range of disciplines to construct a story of walks in downtown Aurora and Chicago, Illinois that illuminates factors at play in the shaping of the pedestrian experience in urban areas.

Changing Attitudes Toward Sustainable Transportation: The Impact Of Meta-Arguments On Persuasion, David M. Sanbonmatsu, David L. Strayer 2017 University of Utah

Changing Attitudes Toward Sustainable Transportation: The Impact Of Meta-Arguments On Persuasion, David M. Sanbonmatsu, David L. Strayer

TREC Final Reports

An experiment tested the effects of both communications about the functions of an attitude and communications about the functions of an attitude object on persuasion. Participants received a conventional message about the benefits of public transportation, a message about the benefits of positive public transportation attitudes, or a control message. Meta-arguments about the functions of attitudes led to more favorable evaluations and stronger intentions to use public transportation. These effects were moderated by the political and environmental orientation of participants. Surprisingly, the conventional message was not persuasive. The research is novel in showing that the communication of the functions of ...


How Does Transportation Affordability Vary Among Tods, Tads, And Other Areas?, Brenda Scheer, Reid Ewing, Keunhyun Park, Shabnam Sifat Ara Khan 2017 University of Utah

How Does Transportation Affordability Vary Among Tods, Tads, And Other Areas?, Brenda Scheer, Reid Ewing, Keunhyun Park, Shabnam Sifat Ara Khan

TREC Final Reports

Transit-oriented development (TOD) has gained popularity worldwide as a sustainable form of urbanism; it concentrates development near a transit station so as to reduce auto-dependency and increase ridership. Existing travel behavior studies in the context of TOD, however, are limited in terms of small sample size, inconsistent TOD classification methods, and failure to control for residential self-selection. Thus, this study has three research questions. First, how can we distinguish between Transit-oriented development (TOD) and Transit-adjacent development (TAD)? Second, how do travel behaviors vary between TODs and TADs? Third, how does transportation affordability vary between TODs and TADs? This study utilizes ...

The Bicycle, The Unsuitable Substitute:A Feasibility Study Based In Fayetteville, Ar Using A Bicycle As A Year-Round Replacement For An Automobile, Jamey Voorhees

Theses and Dissertations

Can a bicycle can be used in place of an automobile for everyday transportation and commuting needs? Fayetteville, Arkansas is a bicycle friendly and they plan continue to expand the current trail system improve other components in the future. Alternative transportation forms like the bicycle are important but only if bikes are integrated into traffic which needs to be done in some way that all involved understand their place in the system. By actively participating in this system I have attempted to show that a bicycle is just not feasible as a form of daily transportation in a city like ...


Simulation Modeling Approach For Evaluating A Solution Designed To Alleviate The Congestion Of Passenger Flow At The Composure Area Of Security Checkpoints, Maria Luisa Janer Rubio 2017 University of Arkansas, Fayetteville

Simulation Modeling Approach For Evaluating A Solution Designed To Alleviate The Congestion Of Passenger Flow At The Composure Area Of Security Checkpoints, Maria Luisa Janer Rubio

Theses and Dissertations

In a previous study, we found that replacing the exit roller of a security checkpoint lane for a continuously circulating conveyor could potentially increase the throughput of passengers by over 28% while maintaining the TSA security-waiting time limit (Janer and Rossetti 2016). This study intends to expand this previous effort by investigating the impact of this circulating conveyor on the secondary screening related processes. Leone and Liu (2011) found that imposing a limit on the x-ray screening time, and diverting any item exceeding this limit to secondary screening, could decrease the waiting time by 43%. Our objective is to verify ...


The Urban Morphology Of Northwest Arkansas: A Geospatial Analysis, Jason McCollum 2017 University of Arkansas, Fayetteville

The Urban Morphology Of Northwest Arkansas: A Geospatial Analysis, Jason Mccollum

Theses and Dissertations

Research on the impacts of transport infrastructure is limited, and most of it is either focused on

rural areas or on developed areas before modern geospatial technologies were available. This study aimed

to fill this gap in transport research by providing a holistic look at the regional changes that occurred due to

new transport infrastructure construction in Northwest Arkansas between 1980 and 2011.

The National Land Cover Database was used to create a time-series of land cover across the

region between 1992 and 2011. These data were then used to predict future growth in the region.

Additionally, growth patterns of ...


Bridge Damage Models For Seismic Risk Assessment Of Oregon Highway Network, Peter Dusicka, Jeffery Roberts 2017 Portland State University

Bridge Damage Models For Seismic Risk Assessment Of Oregon Highway Network, Peter Dusicka, Jeffery Roberts

Peter Dusicka

The highway transportation network of the United States relies on the health and integrity of major infrastructure elements such as bridges. Frequently traveled parts of Oregon are within the seismically active Pacific Northwest and many of the bridges were designed and built to lateral demands that were assumed to be less than the current expectation, a deficiency caused by our growing awareness of seismic hazard and our enhanced understanding of the non-linear response of bridges. This vulnerability to damage from earthquakes can result in not only immediate damage, but also in potentially lingering economic impact caused by the disruption to ...


Application Of Lrfd Geotechnical Principles For Pile Supported Bridges In Oregon: Phase 1, Trevor D. Smith, Peter Dusicka 2017 Portland State University

Application Of Lrfd Geotechnical Principles For Pile Supported Bridges In Oregon: Phase 1, Trevor D. Smith, Peter Dusicka

Peter Dusicka

Bridge foundations must be designed based on acceptable risks of failure. To secure rapid implementation of Load Resistance Factor Design (LRFD) principles for foundation design, the American Association of State Highway and Transportation Officials (AASHTO) and the Federal Highway Administration (FHWA) are requiring their use through AASHTO code. The Bridge Section of the Oregon Department of Transportation (ODOT) has responsibility for satisfactory design of all the bridge structures across the state’s highway system. The widespread geotechnical adoption of the LRFD code throughout state DOTs has been difficult in the case of deep foundations due to regional differences and in ...


Performance Enhancement Of Bridge Bracing Under Service And Extreme Loads, Peter Dusicka, Max Taylor Stephens, Kate Fox-Lent 2017 Portland State University

Performance Enhancement Of Bridge Bracing Under Service And Extreme Loads, Peter Dusicka, Max Taylor Stephens, Kate Fox-Lent

Peter Dusicka

As truck loads continue to get bigger, the demand on many aging bridges increases. Slender steel structural elements widely used in bridge superstructures and braced substructures to resist these loads are built primarily for tension, however, and can buckle under compressive loads. Portland State University associate professor Peter Dusicka set out to develop and demonstrate the concept of retrofitting bridge brace elements with fiber reinforced composites in order to provide restraint against buckling. The advanced materials consisted of a combination of fiber reinforced polymer (FRP) composite pultruded sections and wet lay-up wraps intended to be applied in the field. This ...


Webinar: Land Use Mix And Pedestrian Travel Behavior: Advancements In Conceptualization And Measurement, Steven R. Gehrke 2017 Portland State University

Webinar: Land Use Mix And Pedestrian Travel Behavior: Advancements In Conceptualization And Measurement, Steven R. Gehrke

TREC Webinar Series

Smart growth policies have often emphasized the importance of land use mix as an intervention beholding of lasting urban planning and public health benefits. Past transportation-land use research has identified potential efficiency gains achieved by mixed-use neighborhoods and the subsequent shortening of trip lengths; whereas, public health research has accredited increased land use mixing as an effective policy for facilitating greater physical activity.

However, despite the celebrated transportation, land use, and health benefits of improved land use mixing and the extent of topical attention, no consensus has been reached regarding the conceptualization and measurement of this key smart growth principle ...


The Feasibility Of Road User Fees And Other Alternative Sources Of Transportation Funding, Joshua R. Amberg 2017 Pepperdine University

The Feasibility Of Road User Fees And Other Alternative Sources Of Transportation Funding, Joshua R. Amberg

Pepperdine Policy Review

The nation faces an approaching crisis in transportation funding. This is a critical issue that is both relevant and essential to public administration. It affects all levels of government and extends across the nation. Rapidly declining sources of transportation funding pose short-term and long-term challenges for politicians, public administrators, and everyday citizens. In the face of inadequate revenues, new forms of funding are necessary to keep the transportation system solvent. This paper will briefly outline the history of transportation funding that created this problem and examine various proposed solutions. It will focus specifically on the emerging theory of road user ...

Exploring The Contributions Of Local Health Departments In Land Use And Transportation Policy: Implications For Cross-Sector Collaboration, Meera Sreedhara, Karin V. Goins, Semra Aytur, Katie Heinrich, Jay Maddock, Stephenie C. Lemon

Stephenie C. Lemon

Introduction: Transportation and land use policies can impact physical activity. Local health departments (LHDs) are encouraged to participate in land use and transportation policy processes, which are outside their traditional expertise. Cross-sector collaborations are needed, yet stakeholders’ perceptions of LHD involvement are not well-understood. This paper explores (1) the perceived value of LHD participation in transportation and land use decision-making and (2) potential contributions of LHDs to these processes among relevant stakeholders.

Methods: Qualitative data were analysed from 49 semi-structured interviews conducted in 2015 and 2016. Participants were professionals representing land use planning (n=13), transportation/public works (n=11 ...

Feasibility Study Of A Campus-Based Bikesharing Program At Unlv, Hualiang Teng, Boniphace Kutela, Eneliko Mulokozi, Bingyi Hu, Yang Jiao, Haiqing Li

Mineta Transportation Institute Publications

Bikesharing systems have been deployed worldwide as a transportation demand management strategy to encourage active modes and reduce single-occupant vehicle travel. These systems have been deployed at universities, both as part of a city program or as a stand-alone system, to serve for trips to work, as well as trips on campus. The Regional Transportation Commission of Southern Nevada (RTCSNV) has built a public bikesharing system in downtown Las Vegas, approximately five miles from the University of Nevada, Las Vegas (UNLV). This study analyzes the feasibility of a campus-based bikesharing program at UNLV. Through a review of the literature, survey ...
