Sirisha Kothuri, an OTREC scholar for the past two years and a current Ph.D. candidate at Portland State University, has been awarded one of NITC'S 2013 dissertation fellowships.

The $15,000 fellowship -- funded through an ISS (Institute for Sustainable Solutions) grant -- along with an $800 OTREC/NITC scholarship for the 2012-2013 academic year, will assist Kothuri with her research into pedestrian signal timing.

Sirisha was born and raised in Hyderabad, India, and still misses the heat — or at least, the warmth; she has yet to become completely acclimated to Portland, Ore weather. In Hyderabad she obtained a bachelor's degree in Civil Engineering from Osmania University in 1999. She moved to Baton Rouge, Louisiana in 1999 to get a Master’s degree in Civil Engineering at Louisiana State University.

A visit to Illinois for her brother's graduation opened her eyes to the automobile-centric cities that make up much of the United States. She was surprised at some of the infrastructure in the Midwest, which decidedly favors cars over pedestrian and other means of active transport.

Each year, Portland State University’s MURP, or Master’s of Urban and Regional Planning, program hosts a public presentation to showcase the work of its graduating master’s students. Students who graduate with a Master’s in Urban and Regional Planning spend the last two terms of their program collaborating on workshop projects, completing planning tasks for local clients or business organizations.

This year’s presentations took place on Wednesday, attended by a crowd of about a hundred PSU students, professors, MURP clients and community members. Six groups presented their projects. Some of the projects were transportation-focused, especially one titled "Lombard Re-Imagined."

Swift Planning Group, composed of members Kathryn Doherty-Chapman, Zef Wagner, Brian Hurley, Jake Warr, Rebecca Hamilton, and Jodi Jacobson-Swartfager, developed a plan to improve Lombard Street, a key transportation corridor in North Portland.

The challenge facing the group had to do with the many roles that Lombard street plays. The street is both an arterial throughway and a state highway. It is an overdimensional freight route, for trucks that are too big to go anywhere else in North Portland, and it has also been designated as a main street in Metro’s 2040 Growth Concept. The various...

When planning their daily commute, most drivers account for the traffic they know is unavoidable: at peak times of day, like morning and afternoon rush hour, they probably allow extra time to get where they’re going.

The delays that are harder to accept are the unexpected ones, when accidents, road work, or a traffic bottleneck turn a thirty minute trip into an hour.

This unpredictable postponement leads to natural frustration on the part of drivers, as it may cause them to be late to work or late picking up children from school. A reliable road network is one in which this is a rare occurrence.

A project led by Portland State University’s Miguel Figliozzi explored the value of this travel-time reliability using a study of commuters’ route choice behavior, taking a look at the trade-offs between reliability, traffic congestion, and air pollution.

The details for the combined project can be found here.

In the first phase of the research, co-investigators David Levinson and Kathleen Harder of the University of Minnesota sought to measure the route choices drivers made in a real-world setting. Instead of just having people fill out a survey about whether they would choose to take major roads or the freeway to work, this study ambitiously placed GPS units in the cars of...

OTREC has announced eight winners of the “Small Starts” grant program, which launched last December. These grants, made available through a new OTREC initiative, were intended to fund small projects related to transportation and community development. Any eligible professor at Portland State University, Oregon State University, the University of Oregon, or the Oregon Institute of Technology was invited to apply for a grant.

Priority was given to tenure-track faculty who are untenured, and faculty who have not received an OTREC grant in the past. The Small Starts program was conceived for the benefit of researchers who want the chance to undertake a small project that supports innovations in sustainable transportation through advanced technology, integration of land use and transportation, and healthy communities.

A total of $60,000 was available to be awarded; with no individual award larger than $10,000.

Interested faculty turned in their proposals by January 31, 2013. Here are the winners:

• Burkan Isgor, Oregon State University:

“Cracking Susceptibility of Concrete Made with Recycled Concrete Aggregates”

• Donald Truxillo, Portland State University, partnered with ODOT:

“Evaluation of ODOT's Ecodriving Program”

• Bob Bass, Portland State University, partnered with Drive Oregon:

“Impacts of Electric Vehicle Charging on Electric Power Distribution Systems “

• Nancy Cheng, University...
