Staff from OTREC at Portland State University toured three partner campuses to prepare for the first round of projects under the National Institute for Transportation and Communities program, or NITC. Portland State, the University of Oregon, Oregon Institute of Technology and the University of Utah teamed up for the program, funded with a $3.5 million grant from the U.S. Department of Transportation.
The University of Utah was the first to receive a visit, March 19-20, in Salt Lake City. There, NITC executive committee member Keith Bartholomew hosted tours and meetings. Staff met with student representatives from various disciplines and with potential researchers from across campus before meeting potential community partners at the Utah Transit Authority offices. OTREC finance and communications staff members met with their University of Utah counterparts.
The meetings marked the first connection for much of the Utah faculty and OTREC staff. While the University of Oregon and Oregon Tech were already partners under the original OTREC grant, the NITC program marks Portland State and Utah’s first formal collaboration under the federal University Transportation Centers program.
On April 9, staff met with current and potential transportation researchers at the University of Oregon...

For rapid transportation mode-share changes, it’s hard to beat Kunming, China, where OTREC Director Jennifer Dill is visiting this week. In recent years, car and transit trips have quadrupled. Bicycling, which used to account for more than half of trips, now makes up less than a quarter.
Dill is with a team visiting Kunming as part of the PSU-China Innovations in Urbanization program.The visit is led by professor Connie Ozawa, director of Portland State University's Nohad A. Toulan School of Urban Studies & Planning (TSUSP), and includes: professor Yiping Fang; practitioner-in-residence Gill Kelley, former planning director of the city of Portland; Dean Marriott, city of Portland’s director of environmental services; and Jianhong Ye, a post-doctorate fellow at TSUSP.
The team participated in a workshop with over 50 planners from the region, sharing information on how Portland plans for sustainability. The visit is hosted by the Energy Foundation and the city of Kunming.
Like many cities in China, .jpg)
Kunming is facing tremendous growth pressures and increasing motorization. Between 1995 and 2011, car ownership went up from 20 cars per 1,000 people to 150 per 1,000. As a...
While the public street system makes up a huge portion of our public space, streets don’t contribute less to public life than they could, Denver Igarta of the Portland Bureau of Transportation told an OTREC seminar April 12 in Portland.
That’s not the case in Europe, said Igarta, a multimodal urban planner and a principal author of the Portland Bicycle Plan. He spent last November on a fellowship in Europe sponsored by the German Marshall Fund, with a week each in Munich, Rotterdam, Copenhagen and Malmö.
While street design manuals in the United States largely consider how directly and smoothly a street moves people along their route and to a destination, many European streets serve another official function, Igarta said: they encourage people to stay and live their public lives. European urban streets fill some of the same roles as American urban parks: attractive places to spend time.
This especially holds for small neighborhood streets, Igarta said, where moving traffic is secondary to fostering public life.
Igarta demonstrated the type of planning that can create livable streets with a comparison between German and American standards. Under Germany’s national street-construction manual, designers first consider whether the street’s highest emphasis should be on moving traffic, creating an attractive public place or parking. Other considerations then follow, Igarta said, including how wide to make the street.
In the United States, most...

Although specialized equipment and vehicles make up a large portion of state transportation budgets, an OTREC research report found little consistency in how states decide to replace this equipment.
Researchers David Kim and David Porter of Oregon State University surveyed 25 state departments of transportation to determine how they made replacement decisions. Nearly all consider the age of the vehicle or piece of equipment, with many considering how much use it gets.
Around half use thresholds, such as number of miles or months in service, to identify candidates for replacement. Some consider the equipment’s repair cost or operating cost, while others rely on physical inspections. None explicitly considers greenhouse gas emissions or other environmental concerns in its replacement criteria.
Given the huge range of approaches, Kim and Porter wondered if modeling could lead to better decision-making. They ran various models against the simple approach of using equipment age as a threshold value.
As it turns out, the simple approach isn’t too bad. In fact, it does better than one complicated mathematical model and about the same as a second model.

Transportation models keep growing more sophisticated. But complicated isn’t necessarily better, Rick Donnelly said during the inaugural seminar in OTREC’s spring 2012 transportation seminar series April 6.
“Better is contextual,” Donnelly said.
Donnelly, who leads the modeling and simulation practice at engineering consultancy Parsons Brinckerhoff, opened the spring seminar series with an introduction to models. Seven more free seminars follow in the series, produced in partnership with the Oregon Modeling Collaborative.
Donnelly detailed questions that model builders and users should ask and offered his thoughts on building more useful and informative models. Click here for a link to the archived presentation.
Although transportation models consider increasingly more information, simpler models can often get the job done with a smaller investment of time and money, Donnelly said. Sometimes the simplest approach actually produces the best results.
“’Better’ is only relevant in the context of what the model is going to be used for,” he said.
The modeling series continues Friday, April 13 with another seminar geared toward non-modelers. The seminar, by Ben Stabler, also of Parsons Brinckerhoff, builds on Donnelly’s opening installment.
Stabler will discuss two approaches to travel modeling and give...

With persistently high unemployment, it’s hard to imagine that having too many available transportation jobs constitutes a workforce crisis. But with many local agencies expecting half or more of their employees to be eligible for retirement within five years, that crisis looms.
Against this backdrop, 35 transportation leaders from Portland-area agencies met March 20 for a roundtable discussion of workforce challenges. Portland Mayor Sam Adams and Multnomah County Commissioner Loretta Smith co-chaired the meeting, which included participants from organizations that train and educate as well as those that hire transportation workers.
The group agreed that a skills gap exists: there are plenty of people available to fill future vacancies but overwhelmingly they lack the specialized skills. Welding provides one example. The demand for skilled welders far exceeds the supply. In response, Portland Community College is working to expand its training program in that area.
Elsewhere, the region’s economic plan calls for doubling exports. But if that happens, port operators will face an even bigger struggle to find workers with maritime experience or mastery of specialized software.
Returning military veterans often present a different problem: they have the skills but don’t necessarily have the proper certification. For example, many veterans have extensive experience driving large trucks but lack the commercial driver’s license required to work as a...

On Feb. 21, OTREC joined with the Portland State University Students in Transportation and Planning (STEP) and the Portland-area News Rail~Volutionaries to host a debrief of January’s annual meeting of the Transportation Research Board (TRB) in Washington DC. Portland was well represented at the TRB meeting with a diverse array of students, faculty, and transportation professionals, and this event brought many of those attendees together at the Lucky Labrador pub in northwest Portland to share stories and lessons learned.
For students, the gathering presented an opportunity to showcase the research they presented TRB. Posters lined the room and many attendees donned buttons bearing the enthusiastic encouragement, “Ask me about TRB!” Built-in icebreakers ensured lively discussions about current issues and research in transportation.
Those who did not get to attend TRB were able to experience a little taste of it in Portland, as those who did go had no shortage of tales about the biggest annual gathering of transportation professionals.
STEP members in attendance took advantage opportunity to network with potential future employers and coworkers. To aid the soon-to-be graduates in their job hunts, STEP has created a LinkedIn group containing the profiles and resumes of many STEP members.
Last week in Portland, family, friends, and colleagues gathered to remember one of Oregon’s most stalwart and effective public servants, Gail Achterman. Gail committed her life to furthering environmental and transportation issues to improve the quality of life in Oregon. Her commitment to improving and connecting transportation with land use and environmental policy was the reason she received the 2011 OTREC DeFazio Transportation Hall of Fame Award.
A fourth-generation Oregonian, Gail distinguished herself in law and natural-resource issues (as the Director of the Institute of Natural Resources at OSU) even before her involvement in transportation. As Chair of the Oregon Transportation Commission, Gail provided policy guidance to move the Oregon Department of Transportation (ODOT) toward a sustainable future. She has been instrumental in expanding the focus of ODOT beyond highways to include a complete multi-modal transport system.
Recognizing the importance of working smarter, not harder, Gail championed an aggressive program to advance Oregon’s sophisticated integrated models for transportation, land use and the economy. The program boosted efforts such as the GreenSTEP model to address greenhouse gas emission reductions, research into least-cost planning concepts...

Faced with fewer children walking or bicycling to school, governments and other groups have sought to reverse this decline. Even when there's money to address the issue, however, local governments and school districts don’t know how best to spend it to get more children on foot or bicycle.
OTREC researchers Lynn Weigand and Noreen McDonald stepped into this void with their project, “Evaluation of Safe Routes to School Programs: Qualitative and Quantitative Analysis of Parental Decision-Making.” Their final report is now available.
Existing research only scratches the surface of how parents decide which mode their grade school-aged children take to school. Weigand and McDonald explored the decision-making process with focus groups and tested a new Web-based survey to supplement the limited information gained from existing paper surveys.
Focus groups, in particular, can explain motivations more richly than can survey questions, Weigand said. Parents might select a single survey response, for example, to mean drastically different things.
“Parents cite ‘convenience,’ but that means different things to different parents,” Weigand said. “For some, it means it’s more...
