Friday Transportation Seminar: Speed Management and Speed Reduction in Portland, OR

Friday, October 7, 2022, 11:30am to 12:30pm PDT

Friday Transportation Seminars at Portland State University have been a tradition since 2000. You can join us online or in-person at 11:30 AM. All presentations are recorded and shared on the event page afterwards.

THE TOPIC 

In 2015, the Portland City Council unanimously passed a resolution committing Portland to Vision Zero, the goal to eliminate traffic deaths and serious injuries. An underpinning of Vision Zero is that streets are managed for safe speeds. This presentation will summarize Portland's speed management process, how it relates to achieving Vision Zero, and present two case studies in which speed limits were reduced: (1) a 25 mi/h to 20 mi/h reduction on residential streets and (2) various reductions on arterials and collectors. Reduction sites in which additional treatments were implemented, such as speed humps and fixed speed safety cameras, will also be discussed. Results of the data analysis will be shared, along with next steps in Portland's speed management process.

KEY LEARNING OUTCOMES

  • Knowledge of Portland's Speed Management process and how it impacts safety;
  • The effects of speed limit reductions on observed vehicle speeds for different roadway classifications;
  • The effects of speed limit reductions in conjunction with other treatments on...

Friday Transportation Seminar: Bringing Complete Streets to Reality in State Transportation Projects

Friday, October 14, 2022, 11:30am to 12:30pm PDT

Friday Transportation Seminars at Portland State University have been a tradition since 2000. You can join us online or in-person at 11:30 AM. All presentations are recorded and shared on the event page afterwards.

THE TOPIC 

In order to improve the safety, mobility, and accessibility of state highways, the Washington State legislature directed Washington State Department of Transportation (WSDOT) to incorporate the principles of complete streets in state transportation projects and to plan, design, and construct facilities that provide street access with all users in mind, including pedestrians, bicyclists, and public transportation users. This new requirement was passed as part of the Move Ahead Washington package in the 2022 legislative session and is effective for state transportation projects starting design on or after July 1, 2022 with a project cost of $500,000 or more. This provides a tremendous opportunity to fill in gaps in the active transportation network and build partnerships between WSDOT and local jurisdictions to provide mobility options and increased quality of life in communities across the state. Come learn how complete streets are being implemented in state transportation projects in Washington, and the recipe for implementation that is leading to transformative changes.

Webinar: Community Transportation Academies: Rethinking Effective Community Engagement Around Transportation Decision-Making

Thursday, October 20, 2022, 11:00am to 12:00pm PDT
 

OVERVIEW

This webinar will introduce you to the concept of the Community Transportation Academy (CTA), a model which has been operating in Portland for over 30 years in the form of the Portland Traffic and Transportation (PTT) class. Now catching on in other cities, the project team recently implemented the Wasatch Transportation Academy (WTA) in Salt Lake City. The presenters also include key stakeholders (and guest lecturers) in the WTA, and the PTT instructor. The presentation will include discussions about why CTAs can be good for both community members and transportation agencies/practitioners, and how you can bring a CTA to your city.

KEY LEARNING OUTCOMES

  • How to make interactions between community members and transportation agencies more effective
    How to increase human capital and community capacity by teaching community members how and where they can engage in transportation decision-making processes
    Lessons from transportation agency leaders on why a more educated public can make agency activities work better
    Details on running a community transportation academy

THE RESEARCH

This webinar is based on a study funded by the National Institute for Transportation and Communities (NITC) and conducted at Portland State Uhniversity and the University of Utah. Read more about the research: Launching the Wasatch Transportation Academy.

Friday Transportation Seminar: How COVID-19 Changed Our Cities: Evidence from a Multi-Wave National Survey

Friday, October 21, 2022, 11:30am to 12:30pm PDT

Friday Transportation Seminars at Portland State University have been a tradition since 2000. You can join us online or in-person at 11:30 AM. All presentations are recorded and shared on the event page afterwards.

THE TOPIC 

Human behavior is notoriously difficult to change, but a disruption of the magnitude of the COVID-19 pandemic has the potential to bring about long-term behavioral changes. During the pandemic, people were forced to experience new ways of interacting, working, learning, shopping, traveling, and eating meals. A critical question going forward is how these experiences have actually changed preferences and habits in ways that might persist. We collected a nationally-representative, 3-wave panel survey in the U.S. that aims to shed light on this question. This talk will draw from these data to describe how the pandemic did (and did not) change how we live in cities, what we still don't know, and in which areas urban planners should adjust their assumptions as we look to the future.

KEY LEARNING OUTCOMES

  • Many of the effects of COVID-19 on our lives appear to have been short-lived; many of our 2019 trip making patterns are back.
  • An important exception is the fraction of workers who telecommute; our data suggest telecommuting will be *at least* double its...

Friday Transportation Seminar: Freight Moves the Oregon Economy

Friday, October 28, 2022, 11:30am to 12:30pm PDT

Friday Transportation Seminars at Portland State University have been a tradition since 2000. You can join us online or in-person at 11:30 AM. All presentations are recorded and shared on the event page afterwards.

THE TOPIC 

This presentation provides a broad overview of work conducted by the Oregon Department of Transportation in the field of freight analysis supporting long range planning. The information shared will touch upon the data and tools used to conduct analysis, describe the importance of economic context, and share examples from a range of different analyses. Content will be geared toward building understanding of how analysis is used to guide data-driven decision making in the public transportation sector. The presentation will highlight the importance of testing potential public policy to avoid unintended consequences, evaluate tradeoffs across different policy objectives, and test policy resilience against external forces outside of public agency control.

KEY LEARNING OUTCOMES

  • Exposure to ODOT freight planning
  • Overview of the tools and data relied upon to do this work
  • Real world examples of conducting freight related analysis used in everyday practice of the agency

SPEAKER

Becky Knudson, Senior Transportation Economist, Oregon...

Friday Transportation Seminar: System-level Risk Management of Transportation Structures and Networks

Friday, November 4, 2022, 11:30am to 12:30pm PDT

Friday Transportation Seminars at Portland State University have been a tradition since 2000. You can join us online or in-person at 11:30 AM. All presentations are recorded and shared on the event page afterwards.

THE TOPIC 

Conventional risk assessment approaches in infrastructure management do not fully capture the system-level impact of structural failure or service disruption. As a result, the priorities of preservation projects may be misidentified, leading to suboptimal maintenance schedules and waste of resources. In this presentation, we will first illustrate why conventional risk assessment is not suitable for transportation structures and networks due to interdependency between assets, and then demonstrate how system-level preservation policies can be devised using novel algorithms adapted from the field of deep reinforcement learning. Results from a series of case studies showcase that the system-level risk management is essential to correctly identifying key assets and work priorities, devising adaptive maintenance policies, and lowering life-cycle costs of transportation infrastructure.

KEY LEARNING OUTCOMES

  • Difference between asset- and system-level risk assessment and its implications to infrastructure management
  • ...
