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

PRESENTATION ARCHIVE

Miss the webinar or want a look back?

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....

In honor of our 10-year anniversary, we’re trying something a little different. Instead of brief sessions that introduce you to a topic– we will be offering fifteen half-day workshops that focus on skill building and providing the tools to apply the latest research to practice. These will be hands-on, immersive learning experiences in a small classroom setting.

REGISTRATION

This event is a la carte, and pricing is per workshop. You may attend as few as one, or as many as four workshops.

  • Half-Day Workshop (general admission): $95
  • Half-Day Workshop (student rate): $50

Speaker: Darwin Moosavi, MURP, Portland State University
Topic: Capturing the Ride: Exploring Low-Density Flexible Transit Alternatives in Salem-Keizer

Summary: Current fixed-route transit service provided by Salem-Keizer Transit is inefficient in the low-density neighborhoods of West Salem, South Salem, and Keizer. The lack of sidewalks, non-gridded circuitous streets, and large single-family residential lots all contribute to a lack of ridership. As a result, traditional fixed-route transit service is not cost-effective in these areas. Through a five month planning process, a group of Portland State University graduate students, better known as Paradigm Planning, tackled the task of addressing this problem in each of the three study areas. Paradigm’s planning process explored mode and route options in order to produce a plan that provides innovative and feasible alternatives to current transit service that will better meet the needs of the community. Through an intensive community engagement process, the residents in each neighborhood were given a voice in shaping the future of transit in their neighborhood.

Steve Szigethy and Jamison Kelleher, a team of graduate students in PSU's Master of Urban and Regional Planning program, will present their Planning Workshop project entitled "Imagine 82nd." The project engaged residents, businesses, property owners and students along NE 82nd Avenue in Portland to develop a comprehensive vision for the future of the corridor. Imagine 82nd deals with the portion of 82nd Avenue between the Banfield Expressway and NE Sandy Boulevard, 1.3 miles in length. This particular stretch is home to many retail and service businesses that typify the rest of 82nd Avenue, but it also includes Madison High School, a major corporate headquarters, and a 20-acre vacant brownfield site. At this seminar, Steve Szigethy and Jamison Kelleher will present the vision concepts they developed with the community, with particular emphasis on transportation and land use components.

Summaries:

Evaluating Driver and Pedestrian Behaviors at Enhanced Multilane Midblock Pedestrian Crossings: Case Study in Portland, Oregon This study examines driver and pedestrian behaviors at two enhanced midblock pedestrian crossings in Portland, Oregon. One crossing is on a five-lane arterial with a posted speed of 35/45 miles-per-hour (MPH) and features six rectangular rapid flash beacon (RRFB) assemblies and a narrow median refuge. The other crossing is on a suburban arterial with four travel lanes and a two-way left-turn lane. The crossing is enhanced with four RRFB assemblies and a median island with a “Z” crossing, or Danish offset, designed to encourage pedestrians to face oncoming traffic before completing the second stage of their crossing. Approximately 62 hours of video have been collected at the two locations. A total of 351 pedestrian crossings are analyzed for driver compliance (yielding) rates, pedestrian...

OVERVIEW

The aim of this research is to investigate pedestrian behavior at signalized intersections using state-of-the-art LIDAR sensing technologies and to use this data, along with vehicular data, to develop a more effective multimodal signal control system.

In the presentation, the presenters will describe a novel method of collecting pedestrian crossing behaviors at signalized intersection, discuss the findings and implications of data analytics, and introduce a novel approach to dynamic flashing yellow arrow mechanisms to reduce the conflict between left turn vehicles and crossing pedestrians.

KEY LEARNING OUTCOMES

  • Understand the framework of LiDAR sensing solutions;
  • Understand how to collect pedestrian behaviors at intersections;
  • Understand how to provide new protection for crossing pedestrians with object-tracking technologies.

THE RESEARCH

This webinar is based on a study funded by the National Institute...

Calling all Portland State University transportation students: Join us for a Fall 2021 Back-to-School gathering!

After a year of remote learning, we're excited to be back on campus - starting with our annual Fall mixer for transportation students, staff and faculty. Meet us on the rooftop of the Urban Center Building for a meet-and-greet and free lunch. This will be an outdoor event with room to spread out – please wear a mask to keep everyone safe.

If you're interested in a career in transportation – whether you're enrolled in the PSU school of civil engineering, urban studies, or another transportation-adjacent discipline – this event is for you. RSVP here!

STUDENT LEADERSHIP BOARD

The Students in Transportation Engineering and Planning (ITE-STEP) student group at PSU have been helping students interested in mobility connect across disciplines for many years. STEP hosts professional development events, field tours of transportation infrastructure, game nights, and more! Through STEP, transportation students can get connected to funding for attending trainings and conferences. Additionally, they...

Join us for a three day introductory in-person workshop on R

September 10–12, 9:30am - 4:30pm

Tired of finding errors in your spreadsheets that perpetuate and cascade through your work? Still trying to cram “big” data into tiny worksheets? Wish you had an easier way to easily share data and results with others? Want to better manage and maintain your workflow? Always wanted to learn R and version control but never found the time? If any of your answers are yes, then this course is for you!

After several years of hiatus, we are excited to host an "Intro to R" workshop where we will cover the following:

  • Coding and scripting basics
  • Intro to data wrangling and visualizations
  • Version control & best practices
