Bicyclists cross an intersection with a bike signal, near a red car

What if your bicycle could warn you that a car is coming from a side street you can't see? Or let you know that your front tire is getting a little low, or that you're approaching a pothole that wasn't there yesterday? A NITC research project led by John MacArthur of Portland State University explores how connected vehicle (CV) technologies could encourage an increase in bicycling. As CV technology moves forward in the rest of the transportation system—with buses and connected streetcars requesting early green lights from the traffic signals, and cars chatting with each other about their locations and trajectories—there may be...

TREC Scholar Briana Orr Presents on Portland's E-Scooter Pilot Program in a TREC Friday Transportation Seminar
Sep 20, 2019

Each year, through our Initiative for Bicycle and Pedestrian Innovation (IBPI) program, TREC offers a range of scholarships to assist students pursuing equitable, sustainable, and multimodal transportation. Four Portland State University students were awarded TREC scholarships for the 2019/2020 academic year: Gabriella Abou-Zeid and Darshan Chauhan of civil & environmental engineering, and Philip Longenecker and Briana Orr of urban studies & planning.

Want to apply for a transportation scholarship? Current PSU students may apply for scholarships for the 2020/2021 academic year beginning October 1, 2019 and are due February 1, 2020.


Gabriella Abou-Zeid (IBPI Rex Burkholder and Lydia Rich Scholarship)

Gabby Abou-Zeid is a civil engineering mastesr student working with SUPERLAB at Portland State University. Her research interests include affordable housing, transportation impact analysis, and transit oriented development and its impacts on land values and travel. As a student at the University of Arizona she presented as the lead author on a paper on transit-oriented development in a lectern session at the 2019 annual meeting of...

It's 2019, and with the explosion of mobile technology that has affected all other areas of life, it would seem to be a golden age for people living with visual impairments. Like never before in history, blind, deaf-blind, and low-vision individuals can access a plethora of mobile apps offering a range of services to aid in navigation and wayfinding. But the words "explosion" and "plethora" hint at an underlying problem: there are so many different apps, each one addressing only a segment of their mobility...

NITC Webinar: Arterial Reliability Performance Metrics w Jason Anderson of Portland State

OVERVIEW

With worsening congestion, travel time reliability is increasingly becoming as critical as average travel times in affecting travel choices. Researchers from Portland State University (PSU) partnered with Washington County, Oregon to offer data-driven strategies in prioritizing funding for travel time reliability improvements on their urban arterials. The vast majority of existing research on travel time reliability has focused exclusively on freeways. Avinash Unnikrishnan, Sirisha Kothuri and Jason C. Anderson leveraged Bluetooth sensors provided and deployed by Bluemac Analytics to identify problem areas in the county. Set up at intersections throughout Washington County, the sensors are able to calculate travel time from one intersection to another by matching Bluetooth signals from devices in people's cars. The researchers evaluated the Bluetooth travel time data to understand the temporal variation in travel time reliability metrics on these urban arterials, including factors related to time of day, weather, and holidays. They...

Social Transportation Analytic Toolbox (STAT) for Transit Networks
Jul 31, 2019

 

PRESENTATION ARCHIVE

Miss the webinar or want a look back?

OVERVIEW

This webinar will present an open-source socio-transportation analytic toolbox (STAT) for public transit system planning. This webinar will consist of a demonstration of the STAT toolbox, for the primary purpose of getting feedback from transit agencies on the tool's usefulness. We are especially interested in hearing about any improvements that would aid transit agencies in implementing it.

The STAT toolbox was created in an effort to integrate social media and general transit feed specification (GTFS) data for transit agencies, to aid in evaluating and enhancing the performance of public transit systems. The toolbox enables the integration, analysis, and visualization of two major new open transportation data sources—social media and GTFS data—to support transit decision making. In this webinar, we will introduce how we...

This week, Portland State University’s Transportation Research and Education Center (TREC) releases a new research report comparing equity-oriented programs across several U.S. bike share systems. The research finds a variety of methods in place, ranging from affordability to internal hiring practices and beyond. The report is assisted by Toole Design...

Many cities are reconsidering their reliance on ITE's Trip Generation Manual, now in its 10th edition. 

Kelly Clifton, TREC researcher and associate dean for research of Portland State University's Maseeh College of Engineering & Computer Science, is one of the people leading the charge to identify better, more nuanced ways to anticipate transportation demand; especially person (non-car) trips. In an extended series of TREC projects, Clifton and...
