PSU Transportation Seminar: Transportation Planning in an Aging Society
Friday, October 13, 2023, 11:30am to 12:30pm PDT
Transportation Seminars at Portland State University have been a tradition since 2000. Formerly known as the Friday Transportation Seminar series, we've opened up PSU Transportation Seminars to other days of the week to better accommodate attendance. You can always watch online via Zoom.
PRESENTATION ARCHIVE
THE TOPIC
By 2030, all Baby Boomers (those born between 1946 and 1964) will be 65 and older in the U.S. However, the understanding of how Baby Boomers travel differently from the previous generations, and the opportunities and challenges of older people's travel, do not keep pace with the increasing number of older people.
This presentation starts with an overview of transportation policies for older people and challenges, followed by several empirical studies investigating older people's generational travel differences, vehicle ownership...

Transportation Seminars at Portland State University have been a tradition since 2000. Formerly known as the Friday Transportation Seminar series, we've opened up PSU Transportation Seminars to other days of the week to better accommodate attendance. You can always watch online via Zoom.
PRESENTATION ARCHIVE
THE TOPIC
I have spent much of my professional life advocating for high quality transit infrastructure even if it takes a long time to build. I now believe we must focus on investments that can reduce greenhouse gas generation quickly. I cite some examples of how slowly projects have been built compared to peer nations and explain why.
KEY LEARNING OUTCOMES
- Transit takes longer than it should to build.
- Transit costs too much to both build and operate relative to peers.
- Infrastructure needs are met for the roughly...

THE TOPIC
The Kahramanmaras earthquakes struck Turkiye and Syria on February 6th 2023 causing widespread damage and loss of life. Following the earthquakes, the Geotechnical Extreme Event Reconnaissance (GEER) Association deployed teams to survey damage and collect perishable data on damage to infrastructure related to geotechnical earthquake damage. This presentation describes some of the findings from these reconnaissance activities, focusing on damage to transportation infrastructure and cases that apply to earthquake hazard planning and engineering in the Pacific Northwest.
KEY LEARNING OUTCOMES
- Geotechnical earthquake hazards, including liquefaction and slope failures, can...
Webinar: COVID-19's Impact on Travel: Shifting Multimodal Behaviors
Tuesday, July 25, 2023, 11:00am to 12:00pm PDT
PRESENTATION ARCHVE
OVERVIEW
We present a longitudinal research project using COVID-19 as a natural experiment to examine travel behaviors and attitudes in the Eugene-Springfield Metropolitan Region, OR.
Surveys and interviews were conducted in similar timeframes in 2020 and 2022. Findings reveal that travel activities, including driving, transit, and walking/biking, returned to pre-pandemic levels as society recovered. The pandemic had varying impacts on different modes of travel, with driving likely influenced by the perceived health threat of COVID. Some individuals recognized the feasibility and benefits of alternative modes like walking and biking for certain destinations, leading to less habitual driving.
The study highlights the negative impact on transit users during the emergency period, causing stress and mode switching. These experiences may result in reduced transit use in the future. Increased walking and biking in neighborhoods provide clear benefits, encouraging...
Read moreWebinar: Transportation Resources And Behaviors Among Older Immigrants And Migrants
Thursday, June 8, 2023, 10:00am to 11:00am PDT
PRESENTATION ARCHIVE
OVERVIEW
This presentation reports findings from a cross-sectional survey of older Vietnamese immigrants in the Dallas-Fort Worth, TX metroplex and members of a Hispanic senior center in Hartford, CT. In addition to providing a description of transportation resources and behavior, we present a method for assessing the geospatial "regular activity spaces" of older adults based on the frequency and locations of routine activities. We also present options for assessing the geospatial burden of providing rides to older adults using "ride-provision activity spaces," which entails the frequency and locations of activities for which rides are given. Finally, we discuss the association of transportation-related factors and companionship among members of the senior center in Hartford, CT. Implications for this research include land use policy, assessment for and allocation of public assistance for transportation for older adults, and transportation-related programs to address...

THE TOPIC
Pete Buttigieg, USDOT Secretary of Transportation has described the Manual on Uniform Traffic Control Devices (MUTCD) as “notorious”… and for cities, it has been a challenging document to navigate to implement multimodal solutions. This presentation will share upcoming changes to the Manual, ideas for research to inform practice, and ways that cities can interpret data to make positive change in their community.
KEY LEARNING OUTCOMES
- Identify challenges with language in the MUTCD
- Describe what...
Ann Niles Active Transportation Luncheon 2023: "Roadways for People" featuring Lynn Peterson
Wednesday, May 24, 2023, 11:30am to 1:30pm PDT
THE LECTURE
Roadways for People: Building Safe, Just and Affordable Communities
When Lynn Peterson began working as a transportation engineer, she was taught to evaluate roadway projects based only on metrics related to driver safety, allowable speed for the highest number of cars, project schedule, and budget. Involving the community and collaborating with peers were never part of the discussion. Today, Peterson is a nationally recognized leader in transportation planning and engineering, known for her approach that is rooted in racial equity, guided by a process of community engagement, and includes collaboration with other professionals. Lynn Peterson will draw from her personal experience and interviews with leaders in the field to showcase new possibilities within transportation engineering and planning. Join us in a discussion on how to pave the way towards more inclusive communities.
THE SPEAKER
Author of Roadways for People: Rethinking Transportation Planning and Engineering, Lynn Peterson’s career has led her on a journey from building projects to building communities that work for everyone. Lynn’s...

THE TOPIC
The Portland Regional Transportation Archive Listing (PORTAL) is a publicly available transportation data lake representing the Portland, OR - Vancouver, WA metropolitan region. It was developed by Portland State University in 2003, in cooperation with the Oregon Department of Transportation (ODOT) and other regional partners. As PORTAL celebrates its twentieth anniversary, join us to learn how PORTAL has evolved from archiving a single source of data from one agency to multiple sources of data from multiple regional agencies.
We will discuss the origin of PORTAL, how it works, how we overcome...

PRESENTATION ARCHIVE
THE TOPIC
There have been numerous studies on the relationship between travel behavior and built environment over the last few decades. Prior studies have mostly focused on producing point estimates of model coefficients and ended up with a wide range of estimates for the built environment elasticity of travel behavior, including household Vehicle Miles Traveled. With few exceptions, previous studies use data from a single region or a small number of regions, and thus are not able to sufficiently investigate the regional variation in...
