High-Speed Rail And Equine Issues, Peter J. Haas, Allie Scrivener

Mineta Transportation Institute

Community concerns have been raised about the possible negative impacts of high-speed rail (HSR) service on equestrian areas. Although much is known about the impact of aircraft noise on wild and domestic animals, relatively little information is available on the potential impact of HSR service on equine populations. This study will explore possible conflicts between HSR construction and operations in areas used for equestrian ranching, recreation, and related activities, and identify geographic areas where such conflicts could occur.

Safety Analysis Of Freeway Segments With Unobserved Heterogeneity And Second Order Spatial Effects, Eneliko Mujuni Mulokozi

UNLV Theses, Dissertations, Professional Papers, and Capstones

Safety analysis of freeway networks entails the quantification of crash frequency influencing factors which include roadway and traffic characteristics, environmental factors as well as human factors. This quantification can be used to detect locations with large impacts on the occurrence of crashes which in turn assist engineers and planners to improve safety levels of the network. Roadway characteristics are comprised of the physical elements of the road geometry such as section length, median and right shoulders, speed-exchange lanes, the number of main facility as well as geometry of the entrance from and exit to the main freeway facility. Traffic characteristics …

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 …

Net Effects Of Gasoline Price Changes On Transit Ridership In U.S. Urban Areas, Mti Report 12-19, Hiroyuki Iseki, Rubaba Ali

Mineta Transportation Institute

Using panel data of transit ridership and gasoline prices for ten selected U.S. urbanized areas over the time period of 2002 to 2011, this study analyzes the effect of gasoline prices on ridership of the four main transit modes—bus, light rail, heavy rail, and commuter rail—as well as their aggregate ridership. Improving upon past studies on the subject, this study accounts for endogeneity between the supply of services and ridership, and controls for a comprehensive list of factors that may potentially influence transit ridership. This study also examines short- and long-term effects and non-constant effects at different gasoline prices. The …

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.

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 …

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 …

Towards Effective Design Treatment For Right Turns At Intersections With Bicycle Traffic, David Hurwitz, Mafruhatul Jannat, Jennifer Warner, Christopher M. Monsere, Ali Razmpa

Civil and Environmental Engineering Faculty Publications and Presentations

The overall goal of this research was to quantify the safety performance of alternative traffic control strategies to mitigate right-turning vehicle-bicycle crashes at signalized intersections in Oregon. The ultimate aim was to provide useful design guidance to potentially mitigate these collision types at the critical intersection configurations. This report includes a comprehensive review of more than 150 scientific and technical articles that relate to bicycle-motor vehicle crashes. A total of 504 right-hook crashes were identified from vehicle path information in the Oregon crash data from 2007-2011, mapped and reviewed in detail to identify the frequency and severity of crashes by …

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 …

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 …

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 …

Webinar: Transport Cost Index: A New Comprehensive Performance Measure For Transportation And Land Use, Liming Wang

TREC Webinar Series

Recent federal and state policies are placing increasing emphasis on using comprehensive transportation performance measures to guide transportation decision making processes covering policy areas ranging from mobility, safety, economy and livability, to issues of equity and environment. While it is relatively easy to build consensus on mobility measures that center on the transportation system alone, it is much harder for performance measures to incorporate both transportation and land use, loosely defined as accessibility measures, even with continuous efforts to catalog and design such measures.

Two projects at PSU sponsored by Oregon DOT and National Institute of Transportation Communities (NITC) aim …

The Trade-Offs Between Population Density And Households' Transportation-Housing Costs, Haizhong Wang

PSU Transportation Seminars

As metropolitan area governments and others promote density-promoting “smart growth” policies, finer analysis is needed to quantify the impact of such policies on households' transportation and housing costs. Existing research suggests that households in urban areas trade-off between housing costs and transportation costs, but does not explore how policies to increase urban densities might explicitly impact this balance. Furthermore, the research does not adequately distinguish between the effect of urban area density and the effects of other factors associated with urban area density (e.g metropolitan area size and household incomes) on housing costs. This research uses the 2000 Census Public …

The Backstory: How Livablestreets Advocates Changed Boston, Jeffrey Rosenblum

PSU Transportation Seminars

Local grassroots advocacy organizations play a critical role in shaping the future of cities but receive very little attention in research, especially insofar as understanding the most effective tactics that should be used by these organizations to achieve their objectives. When LivableStreets Alliance was founded in 2005, The City of Boston had 3/8 of one mile of bicycle lanes. Over the past decade, we have seen a sea change. Boston has published a nationally-recognized Complete Streets Guide, MassDOT has incorporated cycle-track designs into several federally-funded projects, and highway overpasses are slated for removal. What is LivableStreets’ role in shifting policy, …

Affordable Housing As A Prerequisite For A Safe, Healthy, Equitable Transportation System: Evidence From A Nationwide Evaluation Of Location Efficiency Within The Low-Income Housing Tax Credit (Lihtc) Program, Arlie Steven Adkins

PSU Transportation Seminars

Mountains of research over the last several decades show that how we get around and how much physical activity we get are closely linked with the built environment of the neighborhoods where we live. This means that the health, economic, and environmental benefits associated with active travel and transit are place-based and that affordable housing in walkable, location efficient places needs to be thought of as a critical component of planners’ efforts to provide safe, healthy, and equitable transportation systems. This talk will provide an overview of the links between affordable housing and transportation planning and present research findings from …

Evaluation Of A Shared Space Alternative In Morgantown, Wv, Avinash Unnikrishnan

PSU Transportation Seminars

Pedestrian and vehicle movement conflicts and the associated safety and efficiency issues have always been addressed in traffic engineering based on the principle of separation through bridges, tunnels, or signals. Pioneered by Hans Monderman, shared space is a new approach in transportation design which inverts this paradigm of separation and designs streets with no demarcations or access restrictions. Shared space has been implemented in a number of cases in Europe with improved efficiency and safety. This research focuses on a specific case study for analyzing the possible implementation of shared space in the United States on the West Virginia University …

Transportation Leadership Education: Portland Traffic And Transportation Course A Case Study And Curriculum, Nathan Mcneil

Urban Studies and Planning Faculty Publications and Presentations

The Portland Traffic and Transportation course serves a number of different purposes. On one hand, it is designed to develop citizens who are informed about the transportation system, including how it got where it is today, what agencies and actors play a role in its operation and development, and how they, as citizens, play a role in its future. In this sense, there is a goal of broadening and deepening the existing knowledge about the system among the general population. On the other hand, there is an implicit goal of encouraging participation in the system with the understanding that doing …

Understanding Interactions Between Drivers And Pedestrian Features At Signalized Intersections, Pei-Sung Lin, Achilleas Kourtellis, Zhenyu Wang, Rui Guo

CUTR Faculty Journal Publications

Florida experienced serious pedestrian safety problems and had the highest pedestrian fatality rate in the U.S. from 2008–2011. Pedestrian safety at signalized intersections is the most serious concern due to frequent and severe conflicts between vehicles and pedestrians. Pedestrian features directly related to pedestrian safety are used to increase driver compliance behaviors and reduce vehicle-pedestrian conflicts. This project aimed to explore driver behaviors at signalized intersections with four identified pedestrian features—“STOP HERE ON RED,” “NO TURN ON RED,” “TURNING VEHICLES YIELD TO PEDESTRIANS,” and “RIGHT ON RED ARROW AFTER STOP” signs—by using an innovative safety data source, the Strategic Highway …

Synergistic Interactions Of Dynamic Ridesharing And Battery Electric Vehicles Land Use, Transit, And Auto Pricing Policies, Caroline Rodier, Farzad Alemi, Dylan Smith

Mineta Transportation Institute

It is widely recognized that new vehicle and fuel technology is necessary, but not sufficient, to meet deep greenhouse gas (GHG) reductions goals for both the U.S. and the state of California. Demand management strategies (such as land use, transit, and auto pricing) are also needed to reduce passenger vehicle miles traveled (VMT) and related GHG emissions. In this study, the authors explore how demand management strategies may be combined with new vehicle technology (battery electric vehicles or BEVs) and services (dynamic ridesharing) to enhance VMT and GHG reductions. Owning a BEV or using a dynamic ridesharing service may be …
