Revisiting Tods: How Subsequent Development Affects The Travel Behavior Of Residents In Existing Transit-Oriented Developments, Nathan Mcneil, Jennifer Dill

TREC Final Reports

Portland State University has worked with the Portland Metro regional government periodically since 2005 to survey occupants of buildings for which developers had received funding from Metro’s Transit-Oriented Development (TOD) Program. This research extends upon the prior TOD surveys in Portland by revisiting a set of developments with a second wave of surveys to understand how the travel behavior of TOD residents may change over time, and what factors influence change in travel patterns. The second-wave surveys, coming 8-13 years after the baseline surveys, include five TODs in the west-side Portland suburbs of Hillsboro and Beaverton, two TODs in East …

Pig Iron To Wrought Iron: Lake Oswego's Transformation From Iron Smelting To The Privatization Of Oswego Lake, Mathew K. Ragsdale

Young Historians Conference

The paper focuses on the interaction between Oregon's public trust doctrine, city ordinances, and private interests surrounding access to Oswego Lake. Areas of study include the early development of Lake Oswego with its prominence in the Oregon iron industry, and its transition from industrial town to weekend retreat to affluent suburb between the late 1800s and mid 1900s. The Lake Oswego Corporation has claimed power over all aspects of the lake, a notion disputed by Oregon's strong public trust doctrine. The city, whose duty is to all residents, has used the lake as a public asset while restricting access to …

Moving Toward Equitable Transit-Oriented Developments By Integrating Transit And Housing, Hongwei Dong

PSU Transportation Seminars

Prior studies show that transit-oriented developments (TODs) increase property values and raise property tax revenue. Property owners reap economic benefit from TODs and public officials use it as evidence to justify the high cost of rail transit. However, renters, who rely on transit more than homeowners, may have to pay higher rent to live in TODs. The location affordability index at the neighborhood level suggests that renters can also benefit from TOD by saving money on transportation costs. Recent studies at the individual level, however, found little evidence that living in TODs reduces transportation expenditure. Using rental data scraped from …

Webinar: Visual Exploration Of Trajectory Data, Nikola Markovic, Mark Franz, Seth Miller

TREC Webinar Series

This webinar will demonstrate the tremendous value of GPS trajectory data in understanding statewide travel patterns and measuring performance. First, Dr. Markovic (U of Utah) will conduct visual exploration of GPS trajectories that capture about 3% of all the trips in Utah. He will briefly discuss the problem of scaling GPS trajectories to the population, and then focus on the use of scaled trajectories in computing origin-destination matrices, vehicle-hours delays, vehicle-miles traveled, and trip-based performance measures. Second, Dr. Franz (CATT Lab) will demonstrate a suite of visual analytics that enables transportation agencies to easily explore terabytes of GPS trajectory data. …

Bus-Bike Designs For The Division Transit Project, Derek Abe, Jesse Stemmier

PSU Transportation Seminars

This seminar is brought to you by the Oregon chapter of the Association of Pedestrian and Bicycle Professionals (APBP), with support from TREC at Portland State.

Transit stops and stations are a confluence of complementary and competing activities - pedestrians accessing businesses, passengers boarding and alighting, and bicyclists zipping through to their destinations. People are moving in different directions, at different speeds, and need to be able to navigate this space safely and comfortably. A common point of conflict is the bus/bicycle interaction when a transit stop is adjacent to a bike lane. Designs for integrating pedestrian and bicycle …

It is our hope that the results of our research will encourage the application of similar corridor selection processes, data collection efforts and multimethod analyses in additional corridors and cities around the country, and will provide a solid basis for policymakers, planners and other stakeholders considering street improvement infrastructure for pedestrian and bicycle mobility to make evidence-based investment decisions.

How Long Can Neoliberalism Withstand Climate Crisis?, Julius Mcgee, Patrick Greiner

Urban Studies and Planning Faculty Publications and Presentations

The climate crisis is proving to be antithetical to the neoliberal machines that define current forms of social organization. On the one hand, reducing fossil fuel consumption, the largest contributor to climate change, requires collaborative efforts. These efforts must take into consideration the foundational role of fossil fuels in modern economies. We must acknowledge, for instance, that most peoples’ livelihoods are tethered to fossil fuels, which recent studies have demonstrated is not the result of random historical development but deliberate policy.1 Fossil fuels continue to be used as a form of social domination—a means to expropriate productive and reproductive …

Connected Vehicle System Design For Signalized Arterials, Xianfeng Terry Yang, Mingyue Ji, Qinzheng Wang

TREC Final Reports

It can be expected that connected vehicles (CVs) systems will soon go beyond testbed and appear in real-world applications. To accommodate a large number of connected vehicles on the roads, traffic signal control systems on signalized arterials would require supports of various components such as roadside infrastructure, vehicle on-board devices, an effective communication network, and optimal control algorithms. In this project, we aim to establish a real-time and adaptive system for supporting the operations of CV-based traffic signal control functions. The proposed system will prioritize the communication needs of different types of CVs and best utilize the capacity of the …

Understanding Economic And Business Impacts Of Street Improvements For Bicycle And Mobility – A Multicity Multiapproach Exploration, Jenny H. Liu, Wei Shi

TREC Final Reports

Many cities across the country, as part of Complete Streets initiatives or to promote community livability and environmental sustainability, have engaged in street improvement or transportation infrastructure upgrade projects that increase access and mobility for pedestrians and bicyclists through a reduction of on-street parking or traffic lanes. With various transportation modes competing for scarce resources (including right-of-way and transportation funding), city planners and transportation agencies often struggle with how to justify these infrastructure investments for non-motorized modes such as bicycling and walking, particularly when driving is still the predominant mode of transportation in most cities. There is a vital need …

The Impacts Of The Bicycle Network On Bicycling Activity: A Longitudinal Multi-City Approach, Wei Shi

Dissertations and Theses

Bicycling is a promising approach to improve health, environment, and economic development of urban places. Theoretically, a bicycle network's component goes beyond lanes and paths, and would generate greater impacts than the sum of its parts. However, most previous research focused on how individual types of bicycle-related infrastructure could promote bicycling. Few empirical studies investigated how bicycle networks impact bicycling activity. This project attempts to address this question. Specifically, how to properly measure bicycle networks, and what impacts bicycle networks have on bicycling activity, e.g. bike ridership and bike mode choice, across different cities and longitudinally.

To address the first …

Webinar: New Travel Demand Modeling For Our Evolving Mobility Landscape, Reid Ewing, Sadegh Sabouri

TREC Webinar Series

Conventional four-step travel demand models are used by nearly all metropolitan planning organizations (MPOs), state departments of transportation, and local planning agencies, as the basis for long-range transportation planning in the United States. A flaw of the four-step model is its relative insensitivity to the so-called D variables. The D variables are characteristics of the built environment that are known to affect travel behavior. The Ds are development density, land use diversity, street network design, destination accessibility, and distance to transit. In this seminar, we will explain how we developed a vehicle ownership model (car shedding model), an intrazonal travel …

When Growth Outpaces Infrastructure: Access To Opportunities In Suburban Boomtowns, Jandel Crutchfield, Courtney Cronley, Kate Hyun

TREC Project Briefs

In the last twenty years, the population increased over 100% in Collin County, Texas. The county is projected to have over 2.4 million residents by 2050 -- more than three times its population in 2010. When enough people flock to an area to call it a boomtown, the population tends to grow much faster than the infrastructure to support it. Where does that leave mobility options for residents? Researchers from the University of Texas at Arlington’s (UTA) School of Social Work and College of Engineering partnered with the Collin County Homeless Coalition (CCHC) to investigate gaps in transportation services and …

Transforming Innovation For Decarbonisation? Insights From Combining Complex Systems And Social Practice Perspectives, Nicola Labanca, Ângela Guimarães Pereira, Matt Watson, Kristian Krieger, Dario Padovan, Laura Watts, Mithra Moezzi, Grégoire Wallenborn, Rebecca Wright, Erik Laes, Multiple Additional Authors

Urban Studies and Planning Faculty Publications and Presentations

Technological innovations seem to be among the great promises for achieving the urgent modernisation of economies towards carbon-neutrality. Ranging from fusion energy, bio-based fuels, carbon capture and storage to PV panels and so-called smart energy systems, plenty of technologies promise to reduce use or greenhouse gas emissions of carbon based energy sources. This techno-centric view disregards to a great extent that technological change affects and is affected by societal practices and norms.

The present paper argues that contemporary methodological approaches informed by complex systems and social practices theories provide urgently needed insights into innovation for decarbonisation. It specifically addresses the …
