Comparing The Promise And Reality Of E-Scooters: A Critical Assessment Of Equity Improvements And Mode-Shift, Michael Glenn Mcqueen
Comparing The Promise And Reality Of E-Scooters: A Critical Assessment Of Equity Improvements And Mode-Shift, Michael Glenn Mcqueen
Dissertations and Theses
In just three years, e-scooters have substantially disrupted and altered the urban mobility landscape. Throughout this period, they have been commonly touted as part of a larger micromobility solution that promises to erase equity barriers and solve the first-mile/last-mile problem. However, few studies in the nascent e-scooter literature have considered these claims. In this study, we surveyed students at Portland State University (n = 1,968) about the role that e-scooters, among other modes, played in meeting their general and university-related travel needs. We then estimated models that incorporated demographics, travel behavior, and latent attitudes distilled using exploratory factor analysis (EFA). …
Utilitarian Skateboarding: Insight Into An Emergent Mode Of Mobility, Michael Joseph Harpool
Utilitarian Skateboarding: Insight Into An Emergent Mode Of Mobility, Michael Joseph Harpool
Dissertations and Theses
In recent years research and planning efforts to enhance the conditions and opportunities for active transportation modes have increased significantly; however, these efforts have primarily focused on pedestrians and bicyclists. Skateboarding and other alternative modes of mobility remain an untapped potential for healthy and sustainable travel. This research addresses numerous knowledge gaps in the literature on utilitarian skateboarding under the larger umbrella of active transportation. Analysis of online survey results and semi-structured interviews with skateboarders in Portland, OR provides insight into the motivations and barriers of traveling by skateboard and the demographics and perceptions of skateboard commuters. Like bicyclists and …
Exploring The Positive Utility Of Travel And Mode Choice, Patrick Allen Singleton
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. …
Land Use Mix And Pedestrian Travel Behavior: Advancements In Conceptualization And Measurement, Steven Robert Gehrke
Land Use Mix And Pedestrian Travel Behavior: Advancements In Conceptualization And Measurement, Steven Robert Gehrke
Dissertations and Theses
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 …
Comparing Mode Shares For Non-Residential Destinations In Urban And Suburban Environments, Tasnia Subrin
Comparing Mode Shares For Non-Residential Destinations In Urban And Suburban Environments, Tasnia Subrin
Civil and Environmental Engineering Master's Project Reports
To ensure facility for multimodal transportation is one of the most important concerns in today's transportation sector, with initiatives being taken to make multimodal transportation popular. The built environment variables have a strong relationship with transportation mode choice, but whether that relationship holds true in urban and suburban neighborhoods in the same manner has not been considered. Using data for three non-residential land uses, this research explores whether the built environment variables in suburban areas influences mode share like it does in urban areas. We used survey data conducted at the establishments regarding respondents' travel characteristics from a previous study, …
Model Selection Analysis Of Depot Level Reparable Asset Retrograde Shipments Within The Continental United States, Michael P. Kossow
Model Selection Analysis Of Depot Level Reparable Asset Retrograde Shipments Within The Continental United States, Michael P. Kossow
Theses and Dissertations
Transportation modal choice for the Air Force retrograde movement of reparable assets within the CONUS is inflexible and is not synchronized with the depot repair process. Additionally, transportation coordinators are compelled by unsynchronized priorities and shipping policies to use express air modes in all cases when the use of LTL modes may be available to meet actual service level requirements at a lower cost, There may be cases where the retrograde shipments of reparable assets via an alternative transportation mode, such as LTL, can still meet fast transportation requirements at an even lower cost than can premium transportation. Historical retrograde …
