THE TOPIC

Portland’s Black population has been heavily impacted by gentrification in the historic Albina community. Nearly half of Portland’s Black population lives in the area east of 82nd Ave, known as East Portland. This has had substantial impacts on both Black households that can continue living in Albina and those living in East Portland. The suburban-esque built environment of East Portland makes it difficult to get around and reach basic necessities. Those living in Albina have taken on exorbitant rents. Both groups suffer from a geographic divide that has made it difficult to rely on family and friends for basic needs like childcare and fulfilling social needs.

This seminar will walk through those difficulties as found through a qualitative study of 27 low-income Black households in Portland. It also highlights the difficulties those households faced using various modes of transportation, why they chose the modes they did, and how they coped with their mode choices. See BikePortland's coverage of the research project: Interviews reveal transportation impacts of Albina displacement.

KEY LEARNING OUTCOMES

• Learn about the need to consider all a household’s needs when planning transportation;
• Learn about the experiences of low-income Black households on various modes of transport;
• Learn about how even a 5-10 mile geographic divide can impact low-income Black household’s ability to make ends meet and how transportation is a large part of that.

THE RESEARCH

Supported by a fellowship from the National Institute for Transportation and Communities (NITC), Steven Howland of Portland State University focused his doctoral research on examining the impacts of gentrification on transportation and social support for black working-poor families in Portland. Read more about the project: Suburban Black Poverty in East Portland: The Role of Transportation in Making Ends Meet.

OVERVIEW

This presentation introduces an innovative spatiotemporal analytical framework and web-based visualization platform developed by researchers at the University of Utah to assist transit agencies in identifying optimal deployment strategies for a battery-electric bus (BEB) system by using a combination of mathematical programming methods, GIS-based analysis, and multi-objective optimization techniques. The framework allows transit agencies to optimally phase in BEB infrastructure and deploy the BEB system in a way that can minimize the capital and operational cost of the BEB system while maximizing its environmental benefits (i.e., emission reduction).

KEY LEARNING OUTCOMES

• Introduction to a bi-objective spatiotemporal optimization model for the strategic deployment of BEBs to minimize the cost of purchasing BEBs, on-route and in-depot charging stations, and to maximize environmental equity for disadvantaged populations.
• The optimization considers the unique constraints imposed by BEB operations in a spatiotemporal fashion.
• We used empirical data to offer a potential framework that can be adopted or expanded by transit agencies to optimally deploy BEBs by accommodating multiple goals and objectives that the transit agencies set forth.
• The research could help transit agencies develop optimal deployment strategies for battery-electric bus systems, allowing planners and decision makers to create transportation systems that better serve livable and sustainable communities.

THE RESEARCH

This webinar is based on a study funded by the National Institute for Transportation and Communities (NITC) and conducted at the University of Utah, Portland State University, and the University of California, Riverside. Read more about the research: Deploying Electric Buses to Improve Air Quality in Low-Income Areas.

OVERVIEW

The world is awash in data, and the data available to transportation analysts and planners is growing by the minute. With this rapid growth, traditional data analysis tools may no longer be effective. Relational databases such as Microsoft SQL Server, PostgreSQL and Oracle are one tool that can be used to manage and query large data sets. In this webinar, we give a brief introduction to relational databases and SQL — the language that is used to communicate with relational databases. Participants will learn the key structures of relational databases (relations, keys and types), and will learn how to write simple SQL queries. We will practice writing SQL queries during the training. Additional resources will be provided for participants who wish to continue practicing their new SQL skills after the training. Join us to learn a bit more about how to manage those large data sets!

KEY LEARNING TAKEAWAYS

• Understand relational database schema: relations, keys and types
• Write single and multiple table SQL queries (e.g. SELECT, JOIN, WHERE)
• Write SQL aggregate queries (e.g. COUNT, SUM)
• Understand the range of queries possible to write with SQL

OVERVIEW

Multimodal transportation systems (e.g., walking, cycling, automobile, public transit, etc.) are effective in increasing people’s travel flexibility, reducing congestion, and improving safety.  Therefore, it is critical to understand what factors would affect people’s mode choices. With advanced technology, such as connected and automated vehicles, cities are now facing a transition from traditional urban planning to developing smart cities. To support multimodal transportation management, this study serves as a bridge to connect speed management strategies of conventional corridors to connected vehicle corridors.

The study consists of three main components. In the first component, the impact of speed management strategies along traditional corridors was evaluated. In the second component, the impacts of the specific speed management strategies, signal retiming and coordination, on transit signal priority (TSP) was studied. Finally, in the third component, the feasibility of using controller event-based traffic data for estimating multimodal signal performance measures was investigated. The research outcomes of this study will help decision-makers understand the data and infrastructure needs in supporting future multimodal planning, operation, and safety tasks.

KEY LEARNING OUTCOMES

• Understand the impacts of speed feedback sign along traditional corridors
• Understand the impacts of signal retiming and coordination, on transit signal priority
• Feasibility of using controller event-based traffic data for estimating multimodal signal performance

THE TOPIC

Wide residential streets in US cities are both a contributor to homelessness and a potential strategy to provide more affordable housing. In residential neighborhoods, subdivision ordinances typically set binding standards for street width, far in excess of what is economically optimal or what private developers and residents would likely prefer. These street width standards are one contributor to high housing costs and supply restrictions, which exacerbate the housing affordability crisis in high-cost cities.

Cities can certainly reduce street widths in new development. But what about existing neighborhoods? Dr. Adam Millard-Ball proposes two strategies through which excess street space can accommodate housing in a formalized way. First, cities could cede part of the street right-of-way to adjacent property owners, either as part of new development or as a means to create space for front-yard accessory dwelling units. Second, cities could permit camper van parking or tiny houses on the right-of-way, analogous to liveaboard canal boats that provide housing options in some UK cities. Many people already live on the streets; and rather than evicting unhoused people from that land, cities might think about how municipal reforms can turn streets into safe and affordable housing.

KEY LEARNING OUTCOMES

• How wide are street rights-of-way in the US, and what is the value of the land under the street?
• How to conceptualize the tradeoffs between land for streets and land for housing and other urban uses
• How to turn streets into housing

THE TOPIC

For a person on a bicycle at intersections, trail crossings, or midblock locations that are signalized, knowing that they have been detected and how long they must wait to receive a green indication is valuable information. This presentation will summarize the findings from the online survey (1,048 responses), observed behaviors (2,428 persons on bicycle), and an intercept survey ( 234 persons) to understand blue light feedback devices and countdown timers at signalized intersections. 

Findings suggest that the design where the blue light was embedded in the sign was more visible to cyclists and observed by higher proportions of cyclists in the field. Results show that a bicycle signal countdown timer elicited high comprehension rates. At all locations, cyclists indicated that the devices improved their waiting experience.

KEY LEARNING OUTCOMES

• Results of comprehension surveys on detection feedback devices
• Insights on improving bicycle infrastructure

OVERVIEW

Drawing from the framework of social determinants of health, the objective of this study is to investigate the cross-sectional association between transportation-related factors and self-perceived physical health among adults in the U.S.

Data for this study were derived from the 2017 National Household Travel Survey. An analytic sample of 71,235 respondents aged 18 and 64 years was analyzed using binary logistic regression. Of the 71,235 respondents examined, 8.9% perceived their physical health to be poor. About 36% of the respondents had fewer vehicles per individuals in the household.

Controlling for the effects of other factors, respondents who had fewer vehicles per individuals in the household were 1.27 times more likely to report poor self-perceived physical health when compared to their counterparts with more vehicles per individuals in the household (AOR=1.27, 95% CI=1.17-1.39). Having higher education, higher income, and homeownership were inversely associated with poor self-perceived physical health.

The findings of this study suggest that as the gap between the number of household members and the number of vehicles present increases, respondents' self-perceived physical health deteriorates due to the uncertainty in having access to transportation when the need arises. Social workers, engineers, and policymakers should begin working on viable solutions to reduce or eliminate transportation barriers and address disparities created by lack of access to reliable transportation.

KEY LEARNING OUTCOMES

• How income inequality manifest in access to transportation
• Transportation as a social determinants of health
• The impact of household vehicle deficit on health

THE RESEARCH

This webinar is based on a study funded by the National Institute for Transportation and Communities (NITC) and conducted at the University of Texas at Arlington.

THE TOPIC

Existing studies surveying transportation planners in Tribal communities have recognized two challenges: (1) that existing planning analysis tools do not always align with Tribal community context and needs, and (2) that it is not always clear what benefits planning provides to transportation project selection and delivery in Tribal communities. These challenges are outlined in a 2020 FHWA Research Needs Statement titled Making Transportation Planning Applicable in Tribal Communities.

This study, therefore, seeks to align available planning analysis tools to Tribal community needs based on a range of contextual factors, and to quantify the benefits of planning analysis in the project selection and delivery processes. Additionally, this study seeks to ensure that any findings optimize Tribal Transportation Program funding decision-making in Tribal communities. The audience for the study is primarily Tribal planning staff and, secondarily, FHWA’s Office of Tribal Transportation staff and other federal agencies and partners.

KEY LEARNING OUTCOMES

• Learn how Tribes align planning tools to the specific Tribal planning need.
• Discuss the challenges and opportunities Tribes face ensuring long-range transportation plans are implementable by Tribal staff.
• Learn how Tribal communities link planning phase to project design, construction, and maintenance.
