Capstones

More people ride bicycles in New York City than ever before, and that number continues to grow. At the turn of the 20th century, this city was the epicenter of a cultural obsession with bicycles, and is on the verge of a second renaissance with these simple machines. This project highlights different iterations of bicycle culture within modern New York City, and the socioeconomic, interpersonal, and self-expressive stories it produces.

Cargo Cycles For Local And Last Mile Delivery: Lessons From New York City, Alison Conway

PSU Transportation Seminars

Cities depend on safe and efficient goods movement to support community livability and a healthy economy. However, delivery of goods in an urban environment presents a tremendous challenge. Traditional motorized vehicles used for goods movement – ranging from cargo vans to box trucks - are inherently incompatible with (1) the multimodal street environments of modern cities, with clean, quiet conditions preferred by residents, and (2) larger environmental sustainability goals. As freight flows continue to grow with the demands of global trade, new urban freight and city logistics solutions are needed.

Cargo cycles – human powered cycles equipped with freight carrying …

Do Tods Make A Difference?, Arthur C. Nelson, Matt Miller, Dejan Eskic, Keuntae Kim, Reid Ewing, Jenny H. Liu, Matt Berggren, Zakari Mumuni

TREC Final Reports

In this report, we present research that measures the outcomes of TOD areas in relation to their metropolitan area controls with respect to (1) jobs by sector; (2) housing choice for household types based on key demographic characteristics; (3) housing affordability based on transportation costs; and (4) job-worker balance as a measure of accessibility. Prior literature has not systematically evaluated TOD outcomes in these respects with respect to light rail transit (LRT), commuter rail transit (CRT), bus rapid transit (BRT), and streetcar transit (SCT) systems. Our analysis helps close some of these gaps. We apply our analysis to 23 fixed-guideway …

Do Speed Humps Help Reduce Vehicular Speeds, Volumes, And Motorist Accidents?, Tanisha Werner

Master's Projects

California has adopted a Complete Streets policy, which requires local municipalities to design roadways that meet the needs of all users (pedestrians, bicyclists, and motorists). This policy, combined with complaints about motorists speeding in residential areas, has been a catalyst for jurisdictions to install traffic calming measures on residential streets. One popular traffic calming measure used in the City of Redwood City is the installation of speed humps. A speed hump is a raised pavement surface that provides a physical reminder for motorists to slow down while traveling over it. Although literature shows that the installation of speed humps can …

The Economic Implications Of Evolving Aviation Funding Policy In Tennessee, Hunter Pressley Mccracken

Masters Theses

The majority of state funding for capital improvements at Tennessee’s general aviation and commercial airports comes through grants awarded from the Tennessee Transportation Equity Trust Fund (TETF). Through a 4.5 percent sales and use tax on the consumption of aviation fuel, users help to fund the continued improvement and maintenance of aviation facilities around the state. Aircraft refueling operations associated with the FedEx “SuperHub” in Memphis were responsible for two-thirds of the TETF’s revenue for Fiscal Year 2014. In response to speculation that FedEx would relocate its refueling operations to reduce its fuel tax liability, the Tennessee General Assembly passed …

Aykut Ölçer

This paper addresses the challenges of managers in the shipping industry to implement energy efficient measures in ship operations and their roles of managing both people and technology under the fulfilment of their corporate social responsibility (CSR). An increasing pressure on shipping companies to concern about marine environment, including energy efficiency, has led managers to consider CSR as their ethical business practices. It is an accepted norm that shipping is generally the most environmentally friendly mode of transport in terms of CO2 produced per ton nautical mile. Despite an extensive amount of research available to improve energy efficiency in shipping, …

Three Bridges, Robert Liberty

PSU Transportation Seminars

In the last decade, three important new bridges in the Portland area were the subject of intense discussion and analysis: the Tilikum Crossing, the Sellwood Bridge and the Columbia River Crossing. One of those bridges is completed, the second is under construction and the third one was canceled.

As a Metro Councilor, Robert Liberty was involved in the decision making process for all three projects. The way in which those projects were analyzed and presented to the public revealed to him a great deal about the many weaknesses in the way we make major transportation investment decisions. Those insights are …

Managerial Segmentation Of Service Offerings In Work Commuting, Steven D. Silver

Faculty Publications

This study reports an implementation of procedures that multivariate methodology make available to assess the relative importance of attributes of service offerings to work commuters. Adaptive choice conjoint analysis was used to derive the importance weights of attributes in available service offering to a commuter sample. A clustering procedure was then used to define homogeneous sub-groups of the sample and the combination of demographic differences that discriminate clusters. Results of this assessment are used to indicate how a market in workcommuting can be segmented on the basis of user indications of the importance of attributes of service offerings.

Webinar: Transportation Academy: Lessons From The Portland Traffic And Transportation Course, Nathan Mcneil

TREC Webinar Series

Community involvement and outreach is an important part of any planning effort, but as planners often find, many times the conversation is a difficult one to carry on. Residents may lack the technical knowledge to understand the intricacies of the system, or they may show skepticism toward the planning process in general. “Transportation Leadership Education,” a NITC education project, offers a guide for communities to stimulate the development of a more involved, educated citizenry.

The Portland Traffic and Transportation course is taught each year to 30-40 Portland residents who want to learn more about how the local transportation system developed …

Blurring The Lines: The Overlapping Interests Of High Altitude Unmanned Aircraft, Commercial Space, And Aviation Policy, Ruth E. Stilwell

Space Traffic Management Conference

The commercialization of space operations, coupled with the rapid development in unmanned aircraft systems creates a new policy dynamic between otherwise disparate industries. Existing structures do not adequately address issues of access, governance, and sovereignty across the distinct domains of air transport, space operations, and high altitude unmanned aircraft operations. Globally, aviation policy and space policy have evolved independently as distinct fields. High altitude unmanned aircraft are rapidly increasing utilization of airspace not previously occupied by civil aircraft or spacecraft, where regulation of both safety and access is sparse. Rather than consider operations in this airspace as a third category …

Model-Based Analytics And Processes For Transportation Investment Alternatives Analyses: From Least Cost Planning To Multi Criterion Evaluation, Jeff Frkonja

PSU Transportation Seminars

Many public and private organizations that make decisions regarding whether and how to invest in transportation assets or programs do so via a structured decision-support process. This talk will address the technical aspects of the family of such processes that use travel demand model outputs—and other sources of quantified performance data—as inputs to analytic tools including benefit cost analysis (BCA) and multi criterion evaluation. Example applications of this framework have included tolling and pricing studies, capital investment alternatives analyses, and programmatic evaluations. Example processes include "Least Cost Planning" frameworks borrowed originally from the power generation industry.

The talk will also …

Where Are The Passengers? A Grid-Based Gaussian Mixture Model For Taxi Bookings, Meng-Fen Chiang, Tuan Anh Hoang, Ee-Peng Lim

Research Collection School Of Computing and Information Systems

Taxi bookings are events where requests for taxis are made by passengers either over voice calls or mobile apps. As the demand for taxis changes with space and time, it is important to model both the space and temporal dimensions in dynamic booking data. Several applications can benefit from a good taxi booking model. These include the prediction of number of bookings at certain location and time of the day, and the detection of anomalous booking events. In this paper, we propose a Grid-based Gaussian Mixture Model (GGMM) with spatio-temporal dimensions that groups booking data into a number of spatio-temporal …

Household Income And Vehicle Fuel Economy In California, Christopher E. Ferrell, David B. Reinke

Mineta Transportation Institute

This white paper presents the findings from an analysis of the fiscal implications for vehicle owners of changing from the current statewide fuel tax to a “road user charge” (RUC) based on vehicle-miles traveled (VMT). Since 1923, California’s motor vehicle fuel tax has provided revenue used to plan, construct, and maintain the state’s publicly funded transportation systems. Over time, improvements in vehicle fuel efficiency and the effects of inflation have reduced both the revenue from the fuel tax and its purchasing power. Thus, there is growing interest among policy makers for replacing the state’s per-gallon fuel tax with an RUC …

Examining The Right To Bicycle: Synergies And Tensions Between Human Rights, Civil Rights, And Planning For Cycling, Aaron Golub

PSU Transportation Seminars

Securing and expanding the broad right to bicycle, including the right to adequate and safe street space and related infrastructure for cycling along with other policies and protections for cyclists, is the obvious goal of cycling advocacy efforts in their various forms. All rights are situated within frameworks for promulgating and insuring they are honored, and the right to cycling is no different. This project investigates how the right to bicycle falls within various rights frameworks, focusing on broad human rights and civil rights frameworks while reflecting as well on traffic safety codes and transportation planning frameworks. While certain aspects …

Introducing The Concept Of Resilience Into Maritime Safety, Jens-Uwe Schröder-Hinrichs Phd, Gesa Praetorius, Armando Graziano, Aditi Kataria, Michael Baldauf

Michael Baldauf

The maritime industry is still characterized by prescriptive standards and reactive approaches in relation to safety and risk management to a large extent. For a very long time, responses to maritime accidents have been in terms of automation, regulation and training. While this as such is not wrong, it does not offer the full potential that concepts of resilience seem to suggest. The typical question that is predominately asked is still why things go wrong when accidents occur and search for causes and explanations is undertaken. An evaluation of the safety level achieved system and a focus on system components …
