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 cities. …

"Are We Building Biking Solidarity": Gendered, Racial, And Spatial Barriers To Bicycling In Portland, Oregon, Kyla Jean Tompkins

Dissertations and Theses

Although Portland, Oregon is widely regarded as a "bike friendly" city, its bike equity remains in question. This thesis explores the barriers to biking that women and people of color face in Portland. This research uses feminist geography scholarship to understand how cycling spaces are unequal for marginalized cyclists. Using data from 28 in-depth, semi-structured interviews with infrequent and marginalized cyclists, I found that gender and race inequalities shape their barriers to biking. A hegemonic white, elite, and masculine bike culture controls the domination of cycling spaces. Women's gendered spatial inequalities are shaped by their childrearing demands, geography of fear, …

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

Student Research – Stevenson Center

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

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 …

Smartphone Sensing Meets Transport Data: A Collaborative Framework For Transportation Service Analytics, Yu Lu, Archan Misra, Wen Sun, Huayu Wu

Research Collection School Of Computing and Information Systems

We advocate for and introduce TRANSense, a framework for urban transportation service analytics that combines participatory smartphone sensing data with city-scale transportation-related transactional data (taxis, trains etc.). Our work is driven by the observed limitations of using each data type in isolation: (a) commonly-used anonymous city-scale datasets (such as taxi bookings and GPS trajectories) provide insights into the aggregate behavior of transport infrastructure, but fail to reveal individual-specific transport experiences (e.g., wait times in taxi queues); while (b) mobile sensing data can capture individual-specific commuting-related activities, but suffers from accuracy and energy overhead challenges due to usage artefacts and lack …

Measuring Fine-Grained Metro Interchange Time Via Smartphones, Weixi Gu, Kai Zhang, Zimu Zhou, Ming Jin, Yuxun Zhou, Xi Liu, Costas J. Spanos, Zuo-Jun (Max) Shen, Wei-Hua Lin, Lin Zhang

Research Collection School Of Computing and Information Systems

High variability interchange times often significantly affect the reliability of metro travels. Fine-grained measurements of interchange times during metro transfers can provide valuable insights on the crowdedness of stations, usage of station facilities and efficiency of metro lines. Measuring interchange times in metro systems is challenging since agentoperated systems like automatic fare collection systems only provide coarse-grained trip information and popular localization services like GPS are often inaccessible underground. In this paper, we propose a smartphone-based interchange time measuring method from the passengers’ perspective. It leverages low-power sensors embedded in modern smartphones to record ambient contextual features, and utilizes a …

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 …

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

Graduate 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

Graduate 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 …

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

Graduate 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 …

Monitoring Airport Service Quality: A Complementary Approach To Measure Perceived Service Quality Using Online Reviews, Kiljae Lee, Chunyan Yu

Publications

Based on 42,063 airport reviews collected from Google Maps, we conducted a sentiment analysis and a topic modeling. We showed that the sentiment scores computed from textual reviews are good estimates of their paired star-ratings (r=0.63, p<0.01). Next, using the LDA (Latent Dirichlet Allocation), we extracted latent topics from the textual reviews and compared them with the standard categories utilized in the Airport Service Quality survey (ASQ). The topics extracted from reviews correspond well with the categories used in ASQ. We, in turn, compared the online ratings with the ratings annually updated by ASQ. While online reviews discuss almost identical topics with those of ASQ, the correlation between the ratings from two was weak (r=0.2). We suggest that the text mining approach using online reviews not only provides an inexpensive, dynamic, and locally customizable means of monitoring airport quality but also complements the standard survey by offering an alternative metric. ><0.01).

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

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 Positive Utility Of Travel And Mode Choice, Patrick Allen Singleton

Dissertations and Theses

Why do people travel? Underlying most travel behavior research is the derived-demand paradigm of travel analysis, which assumes that travel demand is derived from the demand for spatially separated activities, traveling is a means to an end (reaching destinations), and travel time is a disutility to be minimized. In contrast, the "positive utility of travel" (PUT) concept suggests that travel may not be inherently disliked and could instead provide benefits or be motivated by desires for travel-based multitasking, positive emotions, or fulfillment. The PUT idea assembles several concepts relevant to travel behavior: utility maximization, motivation theory, multitasking, and subjective well-being. …

Tracer-Mar: Technique For The Retrospective & Predictive Analysis Of Cognitive Errors Adapted To The Maritime Domain, Jens-Uwe Schröder-Hinrichs, Armando Graziano, Aditi Kataria, Gesa Praetorius

WMU Papers in Maritime and Ocean Affairs

This guidebook is the first of a series of WMU Papers in Maritime and Ocean Affairs. It introduces the Human Error Identification technique TRACEr-Mar (Technique for the Retrospective and predictive Analysis of Cognitive Errors adapted to the Maritime Domain).

Modern socio-technical systems had witnessed a complex co-evolution and interaction of both social and technical aspects in the day-to-day reality. However, when an accident occurs in such complex systems, accident causation models always have to simplify the reality and may therefore be limited for fully understanding all the aspects involved in the failing of the maritime socio-technical system involved in that …
