Webinar: Transportation Benefits Of Polycentric Urban Form, Reid Ewing, Sadegh Sabouri

TREC Webinar Series

A “polycentric” region consists of a network of compact developments connected with each other through high-quality transportation options. Rather than continuing the expanse of low-density development radiating from an urban core, investments can be concentrated on central nodes and transit connections. This development pattern is very popular in Europe and is linked to significant benefits. This presentation is aimed at exploring the academic literature and empirical evidence surrounding polycentric development, analyzing more than 120 regional transportation plans to see how they promote polycentric development, defining types of centers in a hierarchy of centers, quantifying the transportation benefits of polycentric development, …

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). …

Economic And Development Benefits Of Fixed Route Transit Through Denser Housing: A National Assessment, Arthur C. Nelson, Robert Hibberd

TREC Project Briefs

Building upon seven years of research, NITC investigators used economic analysis to determine development outcomes and land use planning implications of different fixed route transit systems (FRT). They have created, analyzed, and shared a nationwide data repository that explores links between transit station proximity and real estate rents, jobs, people, and housing. Earlier research revealed important differences in development outcomes of FRT’s during the 2000’s, but the significantly expanded data repository offers a more representative look at development outcomes after the Great Recession and with 22 new FRT systems added.

The main takeaway from this expanded analysis? Only 5% of …

The Link Between Transit Station Proximity And Real Estate Rents, Jobs, People And Housing With Transit And Land Use Planning Implications, Arthur C. Nelson, Robert Hibberd

TREC Final Reports

This report updates and expands prior research in the genre of research that has used economic base analysis (especially shiftshare) and CoStar commercial rent data to estimate the development outcomes to transit. The study period for prior economic base analysis was 2002-2011and census data for 2000 and 2010, as well as CoStar data for 2013. Prior analysis compared development, demographic and housing outcomes associated with those transit systems during the period before the Great Recession (2000 through 2007) and during recession into recovery (2008 through 2011). Though NITC researchers found important differences in outcomes between the study periods of 2000-2007 …

Capturing The Built Environment-Travel Interaction For Strategic Planning: Development Of A Multimodal Travel Module For The Regional Strategic Planning Model (Rspm), Liming Wang, Brian Gregor, Huajie Yang, Tara Weidner, Anthony Knudson

Urban Studies and Planning Faculty Publications and Presentations

Integrated land use and transportation models have evolved along a spectrum from simple sketch planning models to complex microsimulation models. While each has its niche, they are largely unable to balance the flexibility and realism of microsimulation and the speed and interactivity of simple models. The Regional Strategic Planning Model (RSPM) aims to fill this gap by taking a microsimulation approach while making other simplifications in order to model first-order effects quickly. It enables planners to consider the robustness of prospective policies in the face of future uncertainties by accepting a broad range of inputs and allowing rapid simulations of …

Barriers To “New Mobility”: A Community-Informed Approach To Smart Cities Technology, Aaron Golub, Vivian Satterfield

PSU Transportation Seminars

There is an active debate about the potential costs and benefits of emerging “smart mobility” systems, especially in how they will serve communities already facing transportation challenges. This presentation will describe the results of an assessment of these equity impacts in the context of lower-income areas of Portland, Oregon, based on a mixture of quantitative and qualitative research.

Portland, Oregon’s proposal for the U.S. Department of Transportation’s Smart City Challenge, “Ubiquitous Mobility for Portland,” focuses on developing mobility solutions that would serve traditionally underserved populations (low-income, communities of color, and residents with mobility challenges). This study found that by lowering …

Urbanism Next: How Technology Is Changing Our City, Nico Larco

PSU Transportation Seminars

Advances in technology such as the advent of autonomous vehicles (AV’s), the rise of E-commerce, and the proliferation of the sharing economy are having profound effects not only on how we live, move, and spend our time in cities, but also increasingly on urban form and development itself. These new technologies are changing the ease of transport, the role of transit, and the places we spend our time. These changes will have profound effects on cities including large shifts in land use, changes in street design, a potential reduction on the need for parking, a shift on where we choose …

Metropolitan Centers: Evaluating Local Implementation Of Regional Plans And Policies, Richard D. Margerum, Keith Bartholomew, Rebecca Lewis, Robert Parker, Stephen Dobrinich

TREC Final Reports

The Denver and Salt Lake City Metropolitan Planning Organizations (MPOs) have embarked upon regional visioning strategies that promote development around higher density, mixed use centers with current or future access to transit. This study examines the programs and policies in the Salt Lake City and Denver regions to examine regional vision influence on local planning and the opportunities and constraints facing centers. The research team analyzed local plans over the past several decades, interviewed planners, and examined demographic, land use and transportation characteristics in select centers across the region. We found that the regional vision had a moderate influence on …

Metropolitan Centers Mean Smart Growth, Richard D. Margerum, Rebecca Lewis, Keith Bartholomew

TREC Project Briefs

In this study, a multidisciplinary team from the University of Oregon and the University of Utah examined regional metropolitan center programs and policies in the Salt Lake City and Denver regions. The goal of the study was to examine this topic on two levels. First, to learn how and why local governments have adopted the concepts of metropolitan centers over time and the related supporting and constraining factors. Second, to understand how demographics, land use, and transportation choices have changed over time in the designated centers.

Parking Infrastructure: A Constraint On Or Opportunity For Urban Redevelopment?, Mikhail Chester

PSU Transportation Seminars

Many cities have adopted minimum parking requirements, but we have relatively poor information about how parking infrastructure has grown.

In this research, using building and roadway growth models, we estimate how parking has grown in Los Angeles County from 1900 to 2010, and how parking infrastructure evolves, affects urban form, and relates to changes in automobile travel.

We find that since 1975, the ratio of residential offstreet parking spaces to automobiles in Los Angeles County is close to 1.0 and the greatest density of parking spaces is in the urban core. Most new growth in parking occurs outside of the …

An Analysis Of Cyclist Path Choices Through Shared Space Intersections In England, Allison Boyce Duncan

PSU Transportation Seminars

Shared space is a traffic calming technique as well as urban design concept. Also known as ‘Naked Streets’, this technique strives to fully integrate the roadway into the urban fabric by removing elements such as lane markings, curbs, and traffic signs. By removing these elements and creating a more plaza-like space, these spaces become ambiguous and no user group has priority. The technique is relatively new, and the majority of existing research concerns pedestrians only.

This study focused on intersections in England with the goal of understanding how bicycle riders perceive and travel through shared space intersections.

Using video observations, …
