Webinar: Evaluating Urban Arterial Reliability Performance Metrics

Tuesday, November 19, 2019, 10:00am to 11:00am PST
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 also provided the County with an automated process to clean up their data and remove outliers.

The researchers determined that Tualatin-Sherwood Road has the lowest travel time reliability of the three corridors. Now that Tualatin-Sherwood Road has been identified as having the...

Friday Transportation Seminar: Building Healthy Communities Through Seattle's Growth Policy

Friday, November 22, 2019, 11:30am to 12:30pm PST
Friday Transportation Seminar at Portland State University featuring Dongho Chang, City of Seattle

Friday Transportation Seminars at Portland State University have been a tradition since 2000. You can join us in person at 11:30 AM, or you can also watch online.

THE TOPIC

Seattle is experiencing transformational changes with record-breaking population growth among large scale urban renewal and redevelopment. These changes are occurring in a constrained transportation system that is being reconfigured to meet the mobility needs of vibrant and thriving community. Learn about the policies that provide the roadmap for managing City’s growth, plans that guide where transportation investments are made, and how Seattle will reach the safety goals of Vision Zero.

KEY LEARNING TAKEAWAYS

  • Learn about Seattle's comprehensive planning that guides city decisions on where to build for jobs, housing, and transportation investments.
  • Street typologies used in Seattle that balances access and mobility needs of everyone who uses and travel in the city.
  • Project examples that challenge and change how streets serve our communities to reflect their values.

Webinar: Letting Bike Riders Catch the Green Wave

Tuesday, December 3, 2019, 10:00am to 11:00am PST

OVERVIEW

The "Fast Track" project at the University of Oregon focuses on a mode of transportation that is sometimes left out of vehicle-to-infrastructure, or V2I, conversations: Bicycling. NITC researchers developed an app based on a new technology being integrated into modern cars: GLOSA, or Green Light Optimized Speed Advisory. GLOSA allows motorists to set their speed along corridors to maximize their chances of catching a "green wave" so they won't have to stop at red lights.

This project demonstrates how GLOSA can be used by bicyclists in the same way it is used by motorists, with a test site on a busy car and bike corridor feeding the University of Oregon campus: 13th Avenue in Eugene, Oregon. Researchers developed a smartphone app that tells a cyclist whether they should adjust their speed to stay in tune with the signals and catch the next green. The project demonstrates how university researchers, city traffic engineers, and signal-controller manufacturers can come together to help bicyclists be active participants in a smart transportation system.

THE RESEARCH

This webinar is based on a study funded by the National Institute for Transportation and Communities (NITC) and conducted at the University of Oregon. Read more about the NITC research:...
