Friday Transportation Seminar: Reckoning with Induced Vehicle Travel

Friday, February 4, 2022, 11:30am to 12:30pm PST

Friday Transportation Seminars at Portland State University have been a tradition since 2000. You can join us online at 11:30 AM. Stay tuned for an announcement of the fall term lineup.

THE TOPIC 

Empirical research shows that expanding roadway capacity induces more driving - the so-called "induced travel" phenomenon. However, environmental impact assessments and cost-benefit analyses of roadway capacity expansion projects have historically ignored, underestimated, or mis-estimated this induced travel effect. As a result, they frequently overestimate the projects' potential to relieve congestion and reduce air pollution. That spurred our team at the National Center for Sustainable Transportation (UC Davis) to develop an online tool to facilitate estimation of induced vehicle travel from capacity expansion projects. This presentation will explain the induced travel phenomenon, introduce our induced travel calculator and its offshoots, and discuss how transportation impact analysis is changing.

KEY LEARNING OUTCOMES

The audience will hopefully walk away with an understanding of:

  • the induced travel phenomenon,
  • how the induced travel calculators work, and
  • how they...

STEP Book Club Discussion Group

Friday, February 11, 2022, 2:00pm to 3:30pm PST

Members of the Portland State University Transportation Equity Book Club will convene on Zoom February 11 for a virtual discussion of Bicycle/Race: Transportation, Culture, & Resistance by Adonia Lugo. We'll talk about the book, its message, and the call to action for environmental justice in active transportation.

Published by Microcosm Publishing: "Bicycle/Race paints an unforgettable picture of Los Angeles—and the United States—from the perspective of two wheels. This is a book of borderlands and intersections, a cautionary tale about the dangers of putting infrastructure before culture, and a coming-of-age story about power and identity. The colonial history of southern California is interwoven through Adonia Lugo's story of growing up Chicana in Orange County, becoming a bicycle anthropologist, and co-founding Los Angeles's hallmark open streets cycling event, CicLAvia, along the way. When she takes on racism in the world of national bicycle advocacy in Washington, DC, she finds her voice and heads back to LA to organize the movement for environmental justice in active transportation."

This book club is co-hosted by the Transportation Research and Education Center (TREC) and STEP. The Transportation Research and Education Center (TREC) at...

Transportation Data Webinar: Video-Image Processing Technology for Bikes and Pedestrians

Wednesday, February 16, 2022, 2:00pm to 3:00pm PST

OVERVIEW

Join us for a two-part seminar looking at video-image processing technology for bicyclists and pedestrians.

FIRST PRESENTATION
Bicyclist Distinguishment at Traffic Signals Using Infrared Camera Techology

Shaun Quayle of Washington County, Oregon and Chase Hildner of DKS Associates

The speakers will summarize the goals and evaluation results of Washington County, Oregon's pilot project efforts to leverage infrared video cameras to distinguish bikes on approach at signalized intersections. They will also touch on the signal phasing and timing applications to be employed.

Key Learning Outcomes

  • Understanding of the problem cyclists often face at signalized intersections with legacy detection systems.
  • Results of Washington County's efforts to determine the accuracy of detection systems on distinguishing bicyclists from other roadway users.
  • Awareness of the signal timing applications to enhance cyclist safety.

SECOND PRESENTATION
Ped Counts - A Case Study of Clark County
Subhadipto Poddar of Clark County, Washington

With emerging video detection technologies, traffic detection has seen...

Webinar: Exploring Data Fusion Techniques to Derive Bicycle Volumes on a Network

Thursday, March 10, 2022, 11:00am to 12:00pm PST

OVERVIEW

Planners and decision makers have increasingly voiced a need for network-wide estimates of bicycling activity. Such volume estimates have for decades informed motorized planning and analysis but have only recently become feasible for non-motorized travel modes. Recently, new sources of bicycling activity data have emerged. These derive primarily from GPS-based smartphone apps (e.g. Strava, Ride Report, Map My Ride) and GPS-enabled public bicycle sharing systems. These emerging data sources have potential advantages as a complement to traditional count data, and have even been proposed as replacements for such data, since they are collected continuously and for larger portions of local bicycle networks. However, the representativeness of these new data sources has been questioned, and their suitability for producing bicycle volume estimates has yet to be rigorously explored. This project develops a method for evaluating and integrating emerging sources of bicycle activity data with conventional demand data and methods, and applies the results to several locations to predict network-wide bicycle volumes.

THE RESEARCH

This webinar is based on a study funded by the National Institute for Transportation and Communities (NITC) and conducted at Portland State University and the University of Texas at Arlington. The project is supported by a pooled fund grant. Matched by NITC, funding partners include Oregon Department of...

Friday Transportation Seminar: Addressing Gendered Harassment and Women's Travel Needs

Friday, March 18, 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 at 11:30 AM. Stay tuned for an announcement of the fall term lineup.

THE TOPIC 

This presentation will cover experiences, disparities, and solutions to gendered travel differences. Madeline will discuss research from a worldwide survey of harassment on public transit with specific insights from Los Angeles and research from two agency-led studies in Los Angeles. The talk will cover the large issues that make women's travel needs distinct from their male counter-parts - safety and complex travel patterns and some promising solutions for addressing these disparities.

KEY LEARNING OUTCOMES

  1. Understanding women's key travel differences.
  2. Increased awareness of intersectional issues facing women and differences by race and age.
  3. Ideas for solutions to address gender differences in transportation.
