At TREC, we like to think of the streets of our community as our living laboratory. That laboratory doesn't fit neatly in a ballroom such as the one that hosted the Portland State University Sustainability Celebration May 28.
Fortunately, TREC Communications Coordinator Lacey Friedly had a solution: if we can't take people on a tour of town, we'll take the town to the people. Friedly set to work building Tiny TREC, an interactive display showing 24 TREC research efforts in context. Visitors took small scrolls of paper that described research projects and linked to web pages and full-sized project briefs.

Portland State University today announced that the city of Portland will implement a student design to make one of downtown Portland’s busiest roads safer and more accessible to multimodal traffic.
The “Naito Pilot Project” is a civil engineering senior capstone sponsored by Better Block PDX, the local chapter of a national organization committed to the revitalization of urban spaces. The objective of the project is to increase access for pedestrians and bicycles without disrupting vehicle traffic.
Naito Parkway, a 3.1 mile stretch of arterial road, runs along the west bank of the Willamette River and is the subject of mounting safety concerns. Sidewalks on the east side of the street are not continuous for large stretches and bicycle lanes start and end abruptly. Such issues are exacerbated when large crowds are drawn to the waterfront for events.
“Our city engineers were impressed by the level of quality that the university’s students produced in their traffic control plan,” said Portland City Commissioner Steve Novick, who publicly announced plans to implement the Naito Pilot Project at a press conference today. “I am proud that Portland State University is teaching its engineering students the value of utilizing their skills to create public space, improve safety, and engineer an environment conducive to better health.”
The temporary demonstration is set to run from May 22 to June 5, coinciding with the...

A new study led by Miguel Figliozzi of Portland State University provides a microscopic evaluation of how two advanced traffic control technologies work together.
Powell Boulevard, an east-west arterial corridor in southeast Portland, Oregon, has been the focus of several research studies by Figliozzi’s TTP research lab. The street is a key route for public transit buses as well as pedestrians and cars, but heavy traffic at peak hours often results in delays.
On Powell there are two systems operating concurrently: a demand-responsive traffic signal system called Sydney Coordinated Adaptive Traffic System (SCATS) and a Transit Signal Priority (TSP) system. The TSP in the Portland metro region is designed to give priority to late buses and to boost transit performance.
In previous studies Figliozzi’s lab has analyzed a multitude of factors on Powell Boulevard including traffic congestion, transit times, air quality and cyclists’ intake of air pollutants, and a before/after evaluation of SCATS.
For this study, the researchers used a novel approach to evaluate how well SCATS and TSP work together by integrating three major data sources and video recordings at individual intersections.
Figliozzi’s team worked closely with TriMet and the City of Portland to...

Founded to collect the transportation data created by agencies across the region, Portal had done its job almost too well. The data archive, a program of TREC, had taken in more data than it could make available.
Portal started in 2004 with just one data source: Oregon freeway loop detectors. Over the years, it grew into a truly multimodal data archive, incorporating transit data, traffic signal data, bicycle and pedestrian counts – eight data sources spanning two states and multiple agencies.
Its budget didn’t grow proportionately, however, leaving Portal less able to make use of the data it collected. Portal’s $125,000 in regional transportation money just kept the system running, said Portal director Kristin Tufte. “It was enough money to keep the lights on,” she said.
Given Portal’s potential to help agencies improve operations and researchers to address systemwide issues, that wasn’t enough. The information had to be accessible to make a difference.
A boost in support for Portal is helping to make that possible. With a grant from the Institute for Sustainable Solutions at Portland State, TREC hired a Portal programmer this year to present the data visually.
Though key to Portal’s future...
In 2015, 5th grade classes at Beaverton’s Chehalem Elementary and 5th and 6th graders at Tobias Elementary in Aloha took part in a NITC education project, Investigations in Transportation, co-sponsored by Portland State University, the Portland Metro STEM Partnership and the Oregon Department of Transportation. The students' work yielded functional changes which will likely be made to the parking lots at both schools, resulting in better traffic flow and increased capacity. The unit was designed to teach students real-world applications of core concepts in STEM (science, technology, engineering and mathematics). After exploring several potential engineering challenges at their schools, both groups of students chose to work on the “Parking Lot Dilemma.” Read the full story below.
Two Oregon elementary schools recently had their parking lots redesigned by the students.

After meeting with TREC researchers earlier this year, a team of students from Grant High School in Portland, Oregon developed a mobile app that uses real-time data to help cyclists find available bike parking, and took three awards in Portland State University’s High School Innovation Challenge.
The app, which senses the presence or absence of a bicycle’s tire with a logic box located at the bike rack, could also be used to notify owners if their bicycle is removed (i.e. stolen) when they are not present.
Saturday, April 11 was the third annual High School Innovation Challenge, a STEM competition sponsored by the Maseeh College of Engineering and Computer Science at PSU.
- Read the Oregonian's coverage of the event here.
The Grant team won the awards for Best Presentation, Best Technology Focus, and Audience Favorite, making them the only team entered in the 2015 challenge to receive more than one award.
Team members Cory Koehler, Aubrey Masten, Konon Phillips, Richard Smith, Sarah St. Clair and Alex Taylor met with TREC researchers in mid-February for...

TREC will take part in a regional effort to improve travel on all modes through the Interstate 84 corridor. The project received word of nearly $200,000 in support from the Federal Highway Administration.
The FHWA grant, announced Feb. 24, will go toward a study to see how best to manage traffic through a 45-square-mile corridor, using advanced information technologies and real-time travel information. The study aims to help people make better choices about when and where they travel and how they get there.
Metro will lead the effort, which also includes the Oregon Department of Transportation, TriMet, Multnomah County and the cities of Portland and Gresham. Portland State will participate on the project management team and in a technical advisory role, with the Portal multimodal data archive serving as a key tool for understanding and visualizing data throughout the corridor, including the freeway, arterials, transit lines and bikeways.
The grant was one of 13 awarded from among more than 30 proposals for FHWA’s Integrated Corridor Management grant program. The total project cost is $239,600.
The project team will finish its recommendations by spring of 2016. More information is available through an...
Patrick Singleton, a Ph.D. candidate in civil and environmental engineering at Portland State University, has been selected for a fellowship to attend the 2015 Eno Leadership Development Conference this spring, where he will be able to meet and talk with some of the nation’s top transportation policymakers.
The Eno fellowship is an extraordinary opportunity for transportation students. Only one student from each university transportation program can be nominated by their school, and of those nominated, only 20 fellows nationwide are chosen each year. Those selected as Eno Fellows are invited to come to Washington, D.C., all expenses paid, to meet with federal officials, nonprofit and business organization leaders.
From May 31 to June 4, Singleton will attend a series of meetings, workshops and tours designed to be an introduction to the transportation policy making landscape.
“It’s very exciting. One thing that I’m looking forward to most is the opportunity to have a two-way dialogue, with the other student participants and also with the transportation industry leaders. I’d like to have a dialogue with them, as a grad student and aspiring academic, about how the research I’ve been working on can help inform important transportation policy questions and to address some of our current transportation challenges,” Singleton said.

On Monday, February 23, TREC and the Oregon Department of Transportation conducted controlled tests on various methods for counting cyclists.
Krista Nordback, a TREC research associate specializing in bicycle and pedestrian counting and safety, coordinated the event with ODOT staff in Salem, Oregon.
The testing was part of an ongoing study in which TREC and ODOT are partnering up to determine the most efficient and effective way for Oregon to collect non-motorized counts.
“Counting bicycles and pedestrians is something that ODOT wants to be doing,” Nordback said. “The purpose of this project is to find ways to do that using the equipment they already have or are planning to purchase anyway.”
A pilot project last year, headed by TREC researcher Miguel Figliozzi, tested the accuracy of data collection using signal infrastructure already in place. Researchers analyzed video footage of intersections and compared the number of active travelers with the numbers produced by the counters.
The inductive loops and tube counters in the pilot project failed to yield accurate bicycle counts, so part of Nordback’s study is an attempt to...
