OTREC hosted a “welcome to the neighborhood” reception last week for managers of TriMet.
The regional transit provider for Portland, Ore, just relocated its offices to a building near the OTREC headquarters. TriMet's arrival in Harrison Square, just a few blocks from PSU in downtown Portland, was toasted by an informal gathering: TriMet executives were invited to the OTREC offices Tuesday, Oct 29 for a meet-and-greet.
The two agencies are both deeply involved with transportation in the Portland region, and since they're going to be neighbors now too, OTREC's education and technology transfer program manager Jon Makler arranged the event.
Several members of TriMet's senior staff joined OTREC staff and researchers for an hour of refreshments, research briefings, and a few rounds of "Transit Route Bingo."
OTREC Director Jennifer Dill and TriMet's Olivia Clark, head of government relations, kicked off the meeting with some welcoming remarks, then Makler gave the TriMet managers a brief powerpoint presentation, explaining the various overlapping areas of transportation at PSU. He introduced them to OTREC, IBPI, and PORTAL, and the role each group plays.
The presentation also featured a slide for each faculty researcher, explaining their areas of special interest and...Read more
The U.S. Department of Housing and Urban Development has identified some “livability principles” which include healthy, safe and walkable neighborhoods and safe, reliable and economical transportation choices.
Transit agencies and local governments routinely use metrics to evaluate the performance of transit systems, but a uniform standard of transit data collection does not exist outside of the reporting requirements of the National Transit Database (NTD). Because of the types of data collected for the NTD, the focus of performance measurements is often on ridership and financial performance, leaving aside the question of livability.
In a new project sponsored by OTREC, Principal Investigator Marc Schlossberg, associate professor in the department of planning, public policy and management at the University of Oregon, along with co-investigators Jennifer Dill of Portland State University and Nico Larco, also of the University of Oregon, set out to create a set of tested and refined performance indicators that transit agencies across the nation can use to evaluate and improve their system performance in relation to livability goals.
Traditionally, transit systems are thought of exclusively in their wholeness: how the system serves a region, city or community. In order to evaluate...Read more
An OTREC project recently took an in-depth look at the travel-time and health-related effects of a new implementation of a state of the art adaptive traffic system.
Southeast Powell Boulevard is a multimodal urban corridor connecting highway US-26 through Portland, Oregon. The corridor is highly congested during morning and evening peak traffic hours. In October 2011, an adaptive traffic system called SCATS was deployed.
The primary function of SCATS, or Sydney Coordinated Adaptive Traffic System, is to mitigate traffic congestion. Using sensors (usually inductive loops) at each traffic signal, the system tries to find the best cycle time and phasing along the corridor as traffic demand patterns change.
In this integrated multimodal study, OTREC researchers looked at the corridor’s traffic speed and transit reliability, before and after the implementation of SCATS. In addition, a novel contribution of this study was to study the link between signal timing and air quality.
To determine the impact of SCATS on traffic and transit performance, researchers established and measured performance measures before and after SCATS. The researchers used data provided by TriMet, Portland's transit authority, to compare transit times before and after SCATS as well as traffic volume data from two Wavetronix units that were installed by the City of Portland; these units collect traffic counts, speeds and classifications. For the air quality study, TriMet also...Read more
The Beaverton-Hillsdale Highway, pegged as one of Portland’s high-crash corridors, already attracted the attention of city officials worried about safety. They got more help from Portland State University students during the recently completed term.
Students from civil engineering professor Christopher Monsere’s transportation safety analysis course formed six groups, each studying a piece of the corridor. They presented their findings and recommendations during the course’s open house March 19. The presentation drew officials from local agencies interested in improving corridor safety, including the city of Portland, the TriMet transit agency and the Metro regional government.
The student work dovetails with the city’s own examination of the highway corridor, completed in February. In some cases, as with the Shattuck Road intersection, the students came to many of the same conclusions as city officials, said Wendy Cawley, traffic safety engineer with the Portland Bureau of Transportation. Both found that narrowing the crossing distance could make that intersection safer for pedestrians.
One group looked at the Hillsdale area, recommending a “road diet” approach and other livability-minded changes. While it’s “probably a little more than the city will be able to recommend and handle,” Cawley said, the work has inspired neighborhood...Read more
When policymakers look to meet cycling goals by investing in new bicycle routes, they have little research to help them determine whether cyclists will actually use them. As a result, bicycle facilities aren’t considered equally with motor vehicle infrastructure.
That’s changing, thanks in part to OTREC research. An OTREC-funded study, the first to gather large-scale data that reveal cyclists’ actual route preference, is being published in a scientific journal (Transportation Research Part A). The findings have already been incorporated into the regional travel demand model used to make transportation investment decisions across the Portland region.
In the study, Portland State University researchers Joseph Broach, Jennifer Dill and John Gliebe (Gliebe is now with RSG Inc.) outfitted cyclists with GPS units to record which routes they chose and model the choices to reveal preferences. Previous studies have relied on stated preference surveys or less reliable methods of determining cyclists’ actual routes. The data gathering was supported by a grant from the Robert Wood Johnson Foundation through its national program Active Living Research.
The research...Read more
For transit planning expert Jarrett Walker, one of the fundamentals of transit is also one of the hardest points for people to figure out: you can’t make good transit-system decisions from behind the wheel of a car.
“If you’re a habitual motorist, it doesn’t matter how much you support transit, there are certain things about it you’re not likely to get,” Walker said. “One the most basic, if you’re a motorist or a cyclist for that matter, you’re going to appreciate the concept of speed but not the concept of frequency.
“In urban transit, frequency is vastly more important than speed in determining how soon you get where you're going.”
Walker, the author of “Human Transit: How Clearer Thinking About Public Transit Can Enrich Our Communities And Our Lives,” presents his work at three OTREC-sponsored forums in Eugene and Portland May 16-18. Click here for more information on the presentations and Walker.
While driving or cycling faster typically means arriving earlier, slow transit vehicles that run often will get you to your destination sooner than fast, infrequent ones, Walker said. “It’s very difficult to get motorists to understand that importance. I tell them to imagine a gate at the end of your driveway that only opens once...Read more
The third annual Oregon Transportation Summit drew 275 people to Portland State University for what has become a leading regional venue to connect transportation professionals with each other and with academic researchers. Workshops and plenary sessions spread some of the best ideas in transportation, while a poster session shared the latest research from OTREC faculty and students.
The OTREC awards honored leaders in their field. In an emotional presentation, Chris Achterman accepted the Peter DeFazio Transportation Hall of Fame award on behalf of his sister, Gail Achterman, who recently stepped down as chair of the Oregon Transportation Commission and is undergoing chemotherapy.
Achterman brought a different perspective to the commission, OTREC Director Jennifer Dill said in presenting the award. “Gail’s direction helped the Oregon Department of Transportation redefine itself, emphasizing active and multimodal transportation,” Dill said. “With her diverse background and open mind, she has welcomed the best ideas from multiple disciplines, recognizing their implication for transportation.”
In prepared remarks, Achterman returned the praise. “The Summit is only one of the Oregon...Read more
Even with uncertainty clouding the future of university transportation research, more than 150 people from around the country showed their dedication to providing the most useful transportation research at the Council of University Transportation Centers’ 2011 summer meeting. OTREC hosted the conference June 13-15 at Portland State University.
University transportation researchers and staff, along with federal and state transportation officials, convened for three days of work sessions, meetings and exploring. OTREC-organized tours gave a Portland flavor to the proceedings, letting visitors explore the city by every available transportation mode. The 4T trail took participants on a light-rail train, a trail, an aerial tram and a streetcar (or trolley). The bike tour showed off the bicycle infrastructure that is making Portland nationally known. An architecture walking tour highlighted downtown Portland’s buildings and parks. And the food-and-beer tour explored the city’s burgeoning food-cart scene and copious microbreweries.
For many people, the conference provided the...Read more
