Friday Transportation Seminars at Portland State University have been a tradition since 2000. With over 450 seminars presented and recorded (access the archive of seminars here), we host both visiting and local scholars to share the latest in research, technology, and implementation in transportation.

EVENT OVERVIEW

This research explored driver comprehension and behaviors with respect to right-turn signal displays with a focus on the Flashing Yellow Arrow (FYA) in a driving simulator and a comprehension survey. Flashing yellow arrows are used in place of other turn signals, such as solid green or flashing yellow or red circles, to indicate that drivers may turn after yielding to oncoming traffic. These turns are considered “permissive.” Turns where no conflicting traffic is present, such as those indicated with a green arrow, are “protected” turns. The flashing yellow arrow’s inclusion in the 2009 Manual on Uniform Traffic Control Devices sped up the signal’s adoption to indicate a permissive turn.

Results from a counter-balanced, factorial design were chosen to explore three independent variables separately: signal indication type and active display, length of the right-turn bay,...

We held our annual flagship professional development event, Transportation & Communities, on September 13 and 14. In honor of the event's ten-year anniversary, we changed up the format: Rather than a typical conference with one-hour sessions and a keynote gathering, we offered a selection of intensive half-day workshops. See photos from the event.

The workshops gave practitioners a chance to take a deep dive into new skills in order to walk away with new tools or frameworks that could be applied to their work. We offered a review of congestion mitigation strategies, universal access and equity in pedestrian planning, and discussion on how smart technology could be implemented in suburban communities. Several workshops were based on findings from new research by the National Institute for Transportation & Communities (NITC), the six-university consortium which sponsored the event. The NITC...

Webinar: Addressing Bicycle-Vehicle Conflicts with Alternate  Signal Control Strategies on Oct 16, 2018

OVERVIEW

There is nationwide interest in supporting sustainable and active transportation modes such as bicycling and walking due to the many benefits associated with them, including reduced congestion, lower emissions and improved health. Although the number of bicyclists is increasing, safety remains a top concern. In urban areas, a common crash type involving bicycles at intersections is the “right hook” where a right-turning vehicle collides with a through bicyclist. While geometric treatments and pavement markings have been studied, there is a lack of research on signal timing treatments to address right-hook bicycle-vehicle conflicts.

Addressing Bicycle-Vehicle Conflicts with Alternate Signal Control Strategies, published in April 2018, is the first study to explore bicycle signal control strategies for addressing bicycle-vehicle conflicts. This study analyzed the operational impacts of traditional concurrent phasing, leading bike intervals (LBI), split leading bike intervals, and exclusive bike phasing in a microsimulation environment, and explored the safety impacts of traditional concurrent phasing, leading bike intervals, split leading bike intervals, and mixing zones using video-based conflict analysis. The microsimulation analysis revealed increased delays due to LBI, split LBI and...

Principal Investigators: Kristin Tufte, Portland State University; Larry Head, University of Arizona
Project Overview: NITC Connected Vehicle Platform / Connected Streetcar Project (pending name change)

Learn more about this and other "Smart Cities" technology by registering for this September 14 workshop.

Connected Vehicle (CV) technology is coming to Portland, Oregon. We're excited to announce the first step in what could be a long-term game changer for the city: during the winter of 2018, researchers from Portland State University and University of Arizona will work with the City of Portland to deploy a test concept of CV tech on the Portland Streetcar.

Primarily funded by the National Institute for Transportation and Communities (NITC), the Connected Streetcar Project is one of the Portland Bureau of Transportation’s (PBOT) 2018 Smart Cities pilot projects, and also part of the city’s ...

The National Institute for Transportation and Communities (NITC) is soliciting proposals for our two 2018 Pooled Fund projects:

RFP now open; proposals due Oct 1, 2018

This project will address the need of cities and municipalities to combine bicycle data from different sources (such as manual counts, automatic counts, and crowd-sourced data from apps such as Strava) to assess an accurate accounting of bicycle traffic on a network. Current work on data fusion techniques is limited and additional research is needed to fully understand the choice of weighting techniques, inclusion of spatial vs. temporal variation in the weighting scheme and exploring other...

Missed this class? Sign up for a full-day workshop: R for Transportation Data Science: Application and Best Practices, September 14.

"Scientific Computing for Planners, Engineers, and Scientists," our data science course for transportation professionals, has completed its second year and continues to help planners and engineers improve their data processing workflows.

Taking an ocean of numbers and converting it into compelling infographics, charts and narratives that communicate results is a key part of the transportation profession, and a daunting challenge. That's why we created this week-long data science course. It's also why we're offering a one-day workshop that focuses specifically on transportation...

Portland, Oregon's 2035 Comprehensive Plan calls for “City Greenways” - a citywide network of park-like streets focused on moving pedestrians and bicycles safely. Such a connected network of safe, welcoming active transportation options could have significant benefits for residents—but which residents?

Benefits of bike and pedestrian infrastructure include environmentally sustainable transportation, livability, and improvements in economic development and public health. While these outcomes are well documented, it is also known that both transportation and environmental amenities are typically unevenly distributed in the urban context....

The market for electric vehicles (EVs) is changing dramatically in the United States, and zero-emissions vehicles could replace internal combustion engine automobiles in the near future. Oregon has one of the highest per-capita EV sales markets in the country, and has declared an ambitious goal of complete electrification of the private automobile industry by 2050. This makes Oregon a prime testing ground for the climate-friendly vehicles.

A new study conducted by John MacArthur, a researcher at the Transportation Research and Education Center (TREC) at Portland State University, analyzed survey responses from 4,069 EV owners in Oregon to identify the biggest challenges and opportunities for the emerging industry. Some key findings:

  • EV owners demonstrated a high level of satisfaction with their vehicles;...

With the departing class of 2018, we wanted to shine a light on a group of graduating Portland State University (PSU) masters students that focused their studies and expertise on transportation. 

Three groups of PSU students finishing the Master of Urban and Regional Planning (MURP) program chose to do workshop projects that tackled a specific transportation issue in the Portland area. Michael Harpool, a graduate of PSU's Master of Urban Studies (MUS) program, wrote his masters thesis on utilitarian skateboarding.
