Internships are vital to connecting students with real-world practitioners and applying what they learn in the classroom. For student Stefan Bussey, this real-world experience was gained through working with the Signals, Street Lighting, and ITS Division at the Portland Bureau of Transportation. His assignment during his internship was to evaluate the pedestrian delay at 47 pedestrian crosswalk signals (also known as half-signals) across the city of Portland.
He assisted in reviewing and modifying the signal timing at half-signals to make them more responsive to pedestrians. The changes he helped implement resulted in an overall 25.3% reduction in maximum pedestrian delay for the signals adjusted. The reduction in pedestrian delay at these crossings may help to increase foot trips and higher rates of pedestrian compliance. When asked about his experience working at the city of Portland, Stefan said, “What I got most out of the internship was a better understanding of how to time signalized intersections to better serve non-motorized modes of transportation while maintaining an acceptable level of service for motorized vehicles.” From the employer perspective, Peter Koonce expressed, “The internship was a great example of a student having a positive impact on the surrounding community by solving a real world problem. The City of Portland is fortunate to have the partnerships in place to have PSU work collaboratively to improve the sustainability of the...

Oregon Institute of Technology students got an up-close look at bridge engineering on a large scale during a trip to the Mount Shasta area Sept. 28. A group of 16 students and faculty members Roger Lindgren and Matthew Sleep from the civil engineering department visited the Antlers Bridge Replacement construction site. The trip was organized by Oregon Tech’s Institute of Transportation Engineers student chapter with funding provided by OTREC.
Eric Akana, P.E., of the California Department of Transportation hosted the tour with CalTrans engineers Shari Re, Bill Barnes, and Mark Darnall.
The new Antlers Bridge, which spans the Sacramento River arm of Lake Shasta near the town of Lakehead, California, will be a balanced cantilever cast-in-place concrete bridge. The new bridge will consist of five spans coming together to make a 1,942-foot structure, approximately 600 feet longer than the original Antlers Bridge. The new bridge will replace an aging steel structure that is reaching the end of its service life. In addition, a section of highway south of the bridge will be realigned because of a high accident rate.
The Oregon Tech group met with CalTrans engineers for an extensive project review presentation at the field office and then proceeded to the construction site where they spent over two hours viewing foundation preparation, pier construction, pier-table form travelers, and abutment work.
In addition to viewing construction details and...

OTREC helped celebrate the grand opening of the Oregon Institute of Technology's new Wilsonville campus Oct. 17. Oregon Tech is a founding consortium member of OTREC and a part of the National Institute for Transportation and Communities program.
The new campus features labs for the Renewable Energy Engineering program and consolidates four smaller Portland metro-area sites.
The Portland State University transportation group STEP, for Students in Transportation Engineering and Planning, offered their take on the Oregon Transportation Summit, held Sept. 10 in Portland. The summit featured a poster exhibit with 22 posters, including 19 student posters.
"It was a great experience to talk with professionals in industry and government to get their feedback on the application of our research," Kristi Currans said of research she presented at the summit's poster exhibit.

OTREC held the Oregon Transportation Summit Sept. 10 at Portland State University. The fourth annual summit featured a plenary session on the future of metropolitan planning organizations and workshops on topics ranging from car and bike sharing to the economics of transportation systems. Keynote speaker Eran Ben-Joseph of MIT's City Design and Development program discussed the design and culture of parking. Students presented OTREC-funded research at a poster exhibit.

Some people go to great lengths searching for parking, but perhaps none more so than Eran Ben-Joseph. Ben-Joseph, head of the Joint Program in City Design and Development at the Massachusetts Institute of Technology, had a different mission than most: find a well-designed lot to highlight in his site-planning course.
“Students always ask, ‘Can you show us some good parking lots?’” Ben-Joseph said. “And it was mind-boggling how you just couldn’t find enough.”
Ben-Joseph’s search led to his latest book, “ReThinking a Lot: The Design and Culture of Parking.” Ben-Joseph details his exploration of parking Sept. 10 as the keynote speaker of the Oregon Transportation Summit.
Some parking lots are well vegetated or handle runoff well, Ben-Joseph said. But few stand up as well-planned, well-designed case studies. In part, he said, you get what you ask for. And communities haven’t held lots to comparable standards as buildings or roads.
“From a regulation standpoint, I found that in most cases, the code is very minimal,” Ben-Joseph said. “It might say, ‘You need one tree for every five cars, enter here, exit here,’ but not how to lay it out.”
Parking lots make an easy target, Ben-Joseph said. But he didn’t set out to attack them any more than to defend them.
“Parking is as much of a hot potato as...

Widespread adoption of electric vehicles won’t happen without convenient charging points. But who should provide charging stations? Where should they be located? And how should they be set up?
Those are a few of the questions addressed in an OTREC report on the unique charging-station hub known as Electric Avenue. A block-long bank of chargers on the Portland State University campus, Electric Avenue provides an ideal test site for those seeking to prepare the way for electric vehicles.
Electric Avenue opened in August 2011 with eight parking spaces where vehicle owners can use a variety of chargers for free, paying only the cost of parking. Some chargers can recharge a battery in 30 minutes and others require hours per charge.
As the first installation of its kind, Electric Avenue illuminated both the promise and the difficulties electric vehicles represent. The report concluded that similar projects would be viable elsewhere, especially if planners and policy makers learn from the Electric Avenue experience, including:
- With lead partners Portland State University, the city of Portland and utility Portland General Electric, Electric Avenue had the leadership to steer the project through the inevitable obstacles. A clear understanding of roles and responsibilities helps partners deal with unexpected costs and other challenges. ...
OTREC has selected its first roster of projects under the new National Institute for Transportation and Communities, or NITC, program. The program’s executive committee chose 19 projects, totaling $1.97 million, under the NITC theme of safe, healthy and sustainable transportation to foster livable communities.
The projects have national implications and reflect priority areas including public health, equity and transit. True to the program’s multidisciplinary nature, projects extend beyond transportation engineering and planning to include sociology, chemistry, economics and more—10 disciplines in all.
While Portland State University, the University of Oregon and the Oregon Institute...

When U.S. Sen. Jeff Merkley of Oregon set off on his all-electric drive across the state July 2, his first stop was Electric Avenue, the block-long charging station at Portland State University. Merkley plugged in his car to one of the Electric Avenue charging stations and addressed the crowd gathered on the plaza nearby.
Merkley’s Oil-Free Across Oregon trip is taking him from the Washington border to the California border, “the Columbia to the Redwoods,” he said. Without the recent investments in charging stations along the Interstate 5 corridor, the gaps between chargers would have made an all-electric journey difficult.
“I couldn’t have taken this trip a year ago,” Merkley said. Portland Mayor Sam Adams and Portland State President Wim Wiewel joined Merkley for remarks.
The trip follows the West Coast Electric Highway, a network of DC fast charging stations along I-5. The public charging stations, spaced 25 to 60 miles apart, allow a driver to charge up in 30 minutes or less. OTREC's Transportation Electrification Initiative is guiding the state of Oregon's electric vehicle plan and evaluating the DC fast-charge stations and user behavior to shape future investments.
Merkley is stopping in Salem, Halsey and Springfield on Monday and Roseburg...

With transportation models increasingly used to inform policy decisions at all levels, OTREC is pleased to offer a free educational series designed to help decision makers, transportation officials and others understand these important tools. The series was organized with OTREC’s Oregon Modeling Collaborative and presented during the weekly transportation seminars at Portland State University’s Center for Transportation Studies.
Archived video of the entire eight-week series is now available. Each seminar lasts one hour. Click here for a description of each seminar and links to the video.
While the Friday seminar series has showcased transportation issues for years, the modeling series marks the first time that eight seminars focused on a single theme. Modeling is a timely topic, as policy makers come to rely increasingly on models, whether or not they have a background in modeling.
The series demonstrates how modeling can support better decision-making and explains the tools and the process to a nontechnical audience, said Kelly Clifton, director of the Oregon Modeling Collaborative. Oregon’s discussions regarding modeling tools have helped inform the national discussion, she said.
The final seminar in the series recapped some of the earlier lessons...
