Office Rent Premiums With Respect To Distance From Light Rail Transit Stations In Dallas And Denver, Arthur C. Nelson, Dejan Eskic, Joanna P. Ganning, Shima Hamidi, Susan J. Petheram, Jenny H. Liu, Reid Ewing

Urban Studies and Planning Faculty Publications and Presentations

It seems an article-of-faith that real estate markets respond more favorably to location within one-half mile of transit stations. Planning and public decision-makers have thus drawn half-mile (or smaller) circles around rail transit stations assuming larger planning areas would not be supported by the evidence. Recent research, however, has shown market-responsiveness well beyond one-half mile. We contribute to this literature by evaluating the distance-decay function of office rents in metropolitan Dallas and Denver with respect to light rail transit (LRT) station distance. Using a quadratic transformation of distance we find office rent premiums extending in the range of two miles …

Commuter Rail Transit And Economic Development, Arthur C. Nelson, Matt Miller, Keuntae Kim, Joanna P. Ganning, Jenny H. Liu, Reid Ewing

Urban Studies and Planning Faculty Publications and Presentations

Commuter rail transit (CRT) is a form of rail passenger service connecting downtowns and other major activity centers with suburban commuter towns and beyond. Between 1834 and 1973, only three public CRT systems were built in the U.S. serving New York, Chicago and then Boston. There are now 25 such systems. Modern CRT systems aim to expand economic development in metropolitan areas. But do they? This paper evaluates the economic development performance of five modern CRT systems. The authors find that several economic sectors perform well within 0.50 miles of CRT stations. The authors offer planning and policy implications.

Comparing Two Common Approaches To Public Transit Service Equity Evaluation, Alex Karner, Aaron Golub

Urban Studies and Planning Faculty Publications and Presentations

Understanding the equity effects of transit service changes requires good information about the demographics of transit ridership. Both on-board survey data and census data can be used to estimate equity effects, though there is no clear reason these two sources will result in the same finding of impact. Guidance from the Federal Transit Administration (FTA) recommends using either of these data sources to estimate equity impacts. This article makes a direct comparison of the two methods for the public transit system in the Phoenix, Arizona metropolitan area. The results indicate that, although both sources are acceptable for FTA compliance, the …

But Do Lower-Wage Jobs Follow? Comparing Wage-Based Outcomes Of Light Rail Transit To Control Corridors, Arthur C. Nelson, Matt Miller, Dejan Eskic, Joanna P. Ganning, Jenny H. Liu, Reid Ewing

Urban Studies and Planning Faculty Publications and Presentations

Literature suggests that rail transit improvements should be associated with more jobs and perhaps increasing share of jobs in a metropolitan area. Literature and some research also suggest that such improvements should increase the number of lower-wage jobs accessible to transit. In this paper, we assess both in the context of all 11 light rail transit systems built in metropolitan areas of fewer than eight million residents in the nation since 1981. Using census block-level job data over the period 2002 to 2011, we evaluate change in jobs and change in metropolitan area job share for all jobs, and lower- …

Retail Rent With Respect To Distance From Light Rail Transit Stations In Dallas And Denver, Arthur C. Nelson, Dejan Eskic, Joanna P. Ganning, Shima Hamidi, Susan J. Petheram, Jenny H. Liu, Reid Ewing

Urban Studies and Planning Faculty Publications and Presentations

A growing body of recent research is challenging the assumptions underlying the half-mile-circle in planning for development around transit stations. In this article we review this literature and extend it to include retail land uses. We estimate the rent premium conferred on retail properties in metropolitan Dallas and metropolitan Denver, both of which have extensive light rail transit systems. We find that consistent with half-mile-circle assumptions, retail rent premiums extend only to about 0.30 mile from transit stations with half the premium dissipating after a few hundred feet and three quarters within the first 0.10 mile. We offer implications for …

Workshop Synthesis: Sampling Issues, Data Quality & Data Protection, Jimmy Armoogum, Jennifer Dill

Urban Studies and Planning Faculty Publications and Presentations

This workshop discussed various aspect of the mathematical part of survey methodology, as well as archiving and confidentiality issues aimed at improving data quality and its use through time. Participants identified ways to correct or minimize bias by dealing with incomplete sampling frames, using weighing and imputing procedures. We discussed methods to archive and share GPS-based survey data to preserve anonymity. Finally, we debated research needs on these topics for the next following years.

Crash Frequency Analysis Of Left-Side Merging And Diverging Areas On Urban Freeway Segments: A Case Study Of I-75 Through Downtown Dayton, Ohio, Deogratias Eustace, Aline Aylo, Worku Y. Mergia

Civil and Environmental Engineering and Engineering Mechanics Faculty Publications

This paper analyzes the effect of left- and right-side merging and diverging areas and other variables such as light condition, roadway pavement condition, drivers’ age and presence of construction work zones on the occurrence frequency of crashes. A 6.5-mile (10.5-km) section of I-75 that passes through downtown Dayton, Ohio was considered. The area of interest has a high traffic volume and consists of different geometric design challenges including closely spaced merging and diverging ramps. A four-year record of crash data (2005–2008) and a statistical modeling technique that assumes a negative binomial distribution on generalized linear models (GLMs) were used to …

The Slow Mo' Main Street Concept Plan, Brandi Campbell, Amanda Davidowitz, Neil Heller, Liz Kaster, Matt Lee, Kathy Wilson

Master of Urban and Regional Planning Workshop Projects

Mosier is a community located in the scenic Columbia River Gorge that is "small enough to make a difference." Mosier prides itself on its historic roots, progressive community, its role as a gateway to the agricultural valleys of Eastern Oregon. Unfortunately, Mosier's Main Street, Historic Highway 30, does not reflect the community's commitment to sustainability, economic development, and multimodal transportation. The Slow Mo' Main Street Concept Plan is a high-level guide for future transportation planning along highway 30 in downtown Mosier. The plan outlines conceptual design strategies and programmatic recommendations for Highway 30, to help ensure that Mosier's Main Street …

A Level-Of-Service Model For Protected Bike Lanes, Nick Foster, Christopher Monsere, Jennifer Dill, Kelly Clifton

Civil and Environmental Engineering Faculty Publications and Presentations

Several methods exist for quantifying the quality of service provided by a roadway from a bicyclist’s perspective; however, many of these models do not consider physically protected bike lanes and, of those that do, none is based on empirical data from the US. This is problematic as engineers, planners, and elected officials are increasingly looking to objective performance measures to help guide transportation project design and funding prioritization decisions. This paper addresses this gap by presenting a cumulative logistic model to predict user comfort on protected bike lanes developed from data collected during in-person video surveys. The surveys were conducted …

Feasibility Analysis And Strategic Measures For Promoting Viable New Urban Development, Elizabeth J. Farr

CMC Senior Theses

This thesis demonstrates that New Urbanism is both an advisable and feasible method for reducing carbon emissions to mitigate global climate change. New Urban areas commonly generate lower carbon emissions compared to conventional suburban development due to lower car use and higher levels of walking and use of other forms of transportation. Economic and political feasibility of New Urban development is determined by analyzing case studies, housing price premia, financing, and fiscal impact. The many contexts and perspectives involved in the planning process are analyzed to determine if New Urbanism is advisable in the larger setting in which developers, advocates, …

The Objective Vs. The Perceived Environment: What Matters For Active Travel, Liang Ma

Dissertations and Theses

This study aims to explore the relationship between the objective (actual) environment and people's perceptions of the environment, and their relative effects on active travel behavior, particularly bicycling behavior. This is an important research gap in the current literature linking the built environment and active travel. Better understanding this relationship will help to explore the mechanism underlying the built environment- behavior relationship and identify potential interventions to promote active travel.

Relying on the data from Portland, OR, this study investigated the following four research questions: (1) How does the objectively measured environment correspond to the perceived environment? And what factors …

Evaluation Of Bicyclists Exposure To Traffic-Related Air Pollution Along Distinct Facility Types, James F. Pankow, Miguel A. Figliozzi, Alexander Y. Bigazzi

Civil and Environmental Engineering Faculty Publications and Presentations

While bicyclists and other active travelers obtain health benefits from increased physical activity, they also risk an uptake of traffic-related air pollution. But pollution exposure for urban bicyclists is not well understood due to a lack of direct measurements and insufficient analysis of the determinants of exposure. This knowledge gap impedes pollution-conscious transportation planning, design, and health impact assessment. The research presented in this report generates new connections between transportation system characteristics and pollution exposure for bicyclists. The primary research questions are: 1) How does urban bicyclists’ exposure to air pollution vary with roadway and travel characteristics? and 2) To …

Developing Seamless Connections In The Urban Transit Network: A Look Toward High-Speed Rail Interconnectivity, Tingting Yu

UNLV Theses, Dissertations, Professional Papers, and Capstones

In the past, the studies in the U.S. on high speed rail have been on economic impact. Recently, there are a few studies on the multimodal connectivity at high speed rail stations. High speed rail stations are viewed as hubs that are connected by different modes of public transportation by which passengers are transported to their destinations. How and in which way these different modes are connected to high speed rail stations influence the ridership of high speed rail stations. As the development of high speed rail system in the U.S. has come to the stage for actual design and …

Inclusive Planning To Evaluate Improved Non-Emergency Medical Transportation Services For Patients With End Stage Renal Disease, Jenny Liu, August Benzow

TREC Final Reports

The objective of this project is to design a framework that could be used to evaluate the effectiveness and efficiency of non-emergency transportation services (NEMT) for better livability. In addition to the development of the framework, this project aimed to establish connections between Portland State University (PSU) researchers with regional connections involved in public health research, non-emergency medical transportation, medical services, and medical insurance provision. With the rising costs of transportation and medical costs generally in the United States, it is increasingly important to develop new tools and strategies to reduce these costs while maintaining and improving upon the level …

Evaluating The Level-Of-Service Of Protected Bike Lanes, Nick Foster

PSU Transportation Seminars

Summary: The most recent edition of the Highway Capacity Manual (HCM) contains analysis procedures for measuring the level-of-service (LOS), also referred to as quality of service, provided by an urban roadway to bicyclists. The method uses different design and operating features of the roadway segment (e.g. width, motor vehicle volumes and speeds) to assess an LOS grade of A (best) to F (worst). These procedures are used by planners and engineers to recommend how existing streets could be retrofitted or new streets designed to better serve people on bicycles (and other modes). However, the current HCM does not include methods …

Can Protected Bike Lanes Help Close The Gender Gap In Cycling? Lessons From Five Cities, Jennifer Dill, Tara Goddard, Christopher Monsere, Nathan Mcneil

Urban Studies and Planning Faculty Publications and Presentations

Even in areas with increased levels of bicycling, there remains a significant “gender gap” in bicycling in the United States, in contrast to many other countries with high rates of bicycling. The primary objective of this paper was to explore whether protected bike lanes could help reduce the gender gap. To do so, the authors used survey data from a comprehensive evaluation of protected bike lanes in five large U.S. cities (Austin, TX, Chicago, IL, Portland, OR, San Francisco, CA, and Washington, DC) that included survey responses of 1,111 intercepted bicyclists and 2,283 residents. Both men and women overwhelmingly felt …

Trick Or Treat(Ment)? : Impact Of Route-Level Features On Walk And Bike Decisions, Joseph Broach

PSU Transportation Seminars

Trick or Treatment? Impact of Route-Level Features on Decisions to Walk or Bike Summary: Some travel routes attract people walking and cycling, while others may scare them away. What features of street environments are most important, and how do available routes affect decisions to bike or walk on a specific trip?

Research to date has focused on either large-scale areal measures like "miles of bike lane nearby" or else has considered only shortest path routes. Neither method is suited to capturing the impact of targeted route-level policies like neighborhood greenways. This session will present a new technique for measuring bike …

Informal Transportation In Uganda: A Case Study Of The Boda Boda, Bradley Raynor

Independent Study Project (ISP) Collection

In Uganda’s capital city of Kampala, the closest mode of transport to mass transit that citizens have access to is the 14-seater taxis which fill the streets of Kampala, create traffic jams, and are unable to fulfill the transportation needs of the city’s growing population. In response, motorcycle taxis, called Boda Bodas, which are able to navigate traffic jams, access remote locations where taxis don’t go, and deliver passengers to their destinations in a timely manner, filled the gap in public transportation. Unfortunately, while many riders have organized themselves in associations, the industry remains largely unregulated by the Kampala …

Socio-Spatial Transformation And Contested Space At The Street Level In Latin America: The Case Of Cali, Colombia, Maria Janeth Mosquera Becerra

Dissertations and Theses

Since 2008, more than 50% of the world's population has lived in cities and it is projected that by 2050 around 87% will do so. Designing infrastructure in urban spaces has become increasingly critical for achieving human well-being. This dissertation examines socio-spatial transformation processes related to urbanization, economic development and the marginalization of utilitarian cycling in Cali, Colombia, as a particular expression of the struggle for transportation space occurring in urban areas. The research analyzes (a) the socio-spatial processes that have restricted the use of bicycles as a means of transportation in the city of Cali, Colombia; and (b) the …

Determinants Of Recent Mover Non-Work Travel Mode Choice, Arlie Steven Adkins

Dissertations and Theses

Active transportation modes of walking and bicycling have the potential to help mitigate environmental and health concerns ranging from growing greenhouse gas emissions to increasing rates of obesity. This dissertation investigates how new movers make decisions about active transportation, particularly non-work utilitarian walking, in the context of a new home and neighborhood. New movers are an important, yet often overlooked, population in travel behavior research because they provide an opportunity to observe behavior adoption in new contexts, but also because the roughly one-in-ten Americans who move each year are more likely to consider changes to daily routines, including travel behavior, …

Regulations Of E-Bikes In North America, John Macarthur, Nicholas Kobel

TREC Final Reports

Throughout the world, the electric bicycle (e-bike) industry is growing very quickly. The North American market has been somewhat slow to adopt this technology, which is still considered to be in the “early adopter” phase (Rose & Dill, 2011; Rose, 2011), but in recent years, this has begun to change. But as e-bike numbers increase, so too will potential conflicts (actual or perceived) with other vehicles and non-motorized devices, bicycles and pedestrians, causing policy questions to arise. Indeed, conflicting user groups are petitioning state legislatures and local governments for permission to operate legally on roadways and paths or to ban …

Modeling And Analyzing The Impact Of Advanced Technologies On Transit Performance Measures In Arterial Corridors, Miguel A. Figliozzi, Wei Feng

Civil and Environmental Engineering Faculty Publications and Presentations

Transportation and transit agencies have implemented advanced technologies like transit signal priority (TSP) and Sydney Coordinated Adaptive Traffic System (SCATS) to reduce travel times and improve reliability. However, due to the lack of detailed empirical data, the joint impact of these factors and improvement strategies on bus travel time has not been studied at the stop-to-stop segment level. With the aim of assessing the performance of an existing TSP/SCATS system, this study had access to a unique set of high-resolution bus and traffic signal data. Novel algorithms and performance measures to measure TSP performance are proposed. Results indicate that a …

Assessing Transit Fare Equity In Utah Using A Geographic Information System, Steven Farber, Keith Batholomew, Xiao Li, Antonio Paez, Khandker M. Nurul Habib

TREC Final Reports

The goal of this study is to develop and apply a new method for assessing social equity impacts of distance-based public transit fares. Shifting to a distance-based fare structure can disproportionately favor or penalize different subgroups of a population based on variations in settlement patterns, travel needs, and most importantly, transit use. According to federal law, such disparities must be evaluated by the transit agency, but the area-based techniques identified by the Federal Transit Authority for assessing discrimination fail to account for disparities in distances travelled by transit users. This means that transit agencies currently lack guidelines for assessing the …

Accessibility-Based Transportation Planning: Literature And Applications For Shrinking Cities, Joanna Ganning

TREC Final Reports

For 15 years, scholars have claimed that accessibility-based transportation planning was at the brink of becoming a new paradigm, and yet this hope remains unrealized. Its implementation may lag due to vague definitions when compared to mobility, or because those who would benefit from accessibility-based planning lack political power to rally its support. Possibly, the lag in implementation reflects the missing linkages between theory and application for many contexts. This literature review synthesizes knowledge regarding the applications for accessibility-based transportation planning for shrinking cities along the themes of environmental, social, and economic sustainability. While residents in shrinking cities might especially …

Continuous Data Integration For Land Use And Transportation Planning And Modeling, Liming Wang, Kihong Kim

TREC Final Reports

There is an urgent need for improved models that address the interdependencies between land use and transportation, and considerable new work is underway to develop such models in Oregon and elsewhere. These models and planning practices to integrate land use into the process, however, require the integration of massive amounts of land use data that is messy and incomplete. There have been considerable advances in the treatment of such data problems in other domains, drawing on data mining and machine-learning techniques to address issues in various domains. To date, however, little systematic effort has applied these technological advances to the …

Salem-Keizer Transit Flexible Service Plan, Darwin Moosavi, Brenda Martin, Cj Doxsee, Mike Sellinger, Lauren Wirtis, Matt Berggren

Master of Urban and Regional Planning Workshop Projects

Capturing the Ride is an exploration of flexible transportation options for low-density communities in Salem and Keizer. The current transit system does not serve Keizer, South Salem, and West Salem well; each of these communities has areas with limited or no access to current bus routes. The project intends to provide a service that will better meet the communities’ transit needs than the current system. Over a five-month planning process, Paradigm Planning conducted extensive research and reached out to the public in Keizer, South Salem, and West Salem (herein referred to as the study areas) to determine what kind of …
