Friday Transportation Seminars at Portland State University have been a tradition since 2000. We've opened up PSU Transportation Seminars to other days of the week, but the format is the same: Feel free to bring your lunch! If you can't join us in person, you can always watch online via Zoom.

THE TOPIC
Past research and planning has highlighted the existence of pedestrian injury disparities throughout the US and some local agencies have performed cursory analysis in Oregon. However, no statewide analysis of pedestrian injuries in Oregon has been completed to see how these injury outcomes differ by race and income.
This presentation aims to help better understand the factors...

Topic: Trick or Treatment? Impact of Route-Level Features on Decisions to Walk or Bike
Summary: Some travel routes attract people walking and cycling, while others may scare them away. What features of street environments are most important, and how do available routes affect decisions to bike or walk on a specific trip?
Research to date has focused on either large-scale areal measures like "miles of bike lane nearby" or else has considered only shortest path routes. Neither method is suited to capturing the impact of targeted route-level policies like neighborhood greenways. This session will present a new technique for measuring bike and walk accessibility along the most likely route for a given trip. The method is applied to travel data, and results provide new insight into the relationship between route quality and travel mode choice.
The video begins at 2:12.
Abstract: A new way of measuring Level of Service for bicycles, pedestrians, and transit is planned for the next Highway Capacity Manual. Are these the right tools to help us plan and build the system we want? If not, what answers do these tools give us and how should we use them? This presentation will review the approaches to multi-modal Level of Service at the national and local levels and discuss efforts to validate the HCM methods. It will also cover the effect of our LOS policies on climate change and explore ways that we might tweak our analysis to get a more accurate picture of the transportation system for all users.
Bio: Seleta Reynolds plans, funds, and implements bicycle and pedestrian projects as a consultant for the Seattle office of Fehr & Peers. Seleta contributed to the national Safe Routes to School toolbox and has served as a guest lecturer on transportation planning for San Jose State University, Portland State University, and UC Berkeley. She serves on the Transportation Research Board Pedestrian Committee and as the President of the Association of Pedestrian and Bicycle Professionals. One of her favorite side projects was a collaboration with artists Steve Lambert and Packard Jennings to imagine the future of transportation for the Art on Market Street project in San Francisco. Prior to joining Fehr & Peers in 2001, she was the bicycle and...

OVERVIEW
Intelligent transportation systems (ITS) change our communities by improving the safety and convenience of people’s daily mobility. The system relies on multimodal traffic monitoring, that needs to provide reliable, efficient and detailed traffic information for traffic safety and planning. How to reliably and intelligently monitor intersection traffic with multimodal information is one of the most critical topics in intelligent transportation research.
In multimodal traffic monitoring, we gather traffic statistics for distinct transportation modes, such as pedestrians, cars and bicycles, in order to analyze and improve people’s daily mobility in terms of safety and convenience.
In this study, we use a high-resolution millimeter-wave (mmWave) radar sensor to obtain a relatively richer radar point cloud representation for a traffic monitoring scenario. Based on a new...
