States can reduce greenhouse gas emissions with a broad range of approaches, but none will have much luck without continued support from leaders and the public, according to NITC program research from the University of Oregon. In a conference paper for the annual meeting of the Transportation Research Board in Washington, D.C., a team led by Rebecca Lewis took a close look at the efforts West Coast states have made to reduce emissions from the transportation.

Cutting transportation emissions depends on three variables: vehicle efficiency, fuel carbon content and vehicle miles traveled, or VMT. The paper focuses on the last leg: cutting driving. While more efficient automobiles and alternative fuels have come on the market in recent years, a growing population and longer commutes can wipe out any emissions gains from shifts in fuel economy and fuel type.

Washington, Oregon and California have all passed statutes to cut statewide greenhouse gases below 1990 levels by 2020. The approaches vary in their targets, plans and strategies.

Lewis and her team present the research in a poster session Tuesday, Jan. 12 at the annual meeting of the Transportation Research Board in...

Planners and policymakers make decisions that shape neighborhoods based on the best data they have. Unfortunately, when it comes to predicting where people want to live, those data give an incomplete or inaccurate picture.

Behavioral models often rely on basic socioeconomic data such as household size, income and age. But deciding where to live depends on attitudes toward a tangled mix of transportation, urban form and housing characteristics. A NITC project helped untangle these decisions by creating a framework to understand neighborhood preference.

Steven Gehrke presents some of this project’s research findings Wednesday, Jan. 13 at the annual meeting of the Transportation Research Board in Washington, D.C.

A team led by Kelly Clifton, with Gehrke and Kristina Currans, designed survey techniques that give a clearer picture of the decision-making process. Their work is detailed in the NITC report “Understanding Market Segments for Current and Future Residential Location and Travel Choices.”

Gehrke’s TRB paper details one piece of that research project. The research team presented respondents a series of images...

The NITC program has selected a dissertation fellow for the fall 2015 round of dissertation funding.

Tara Goddard, a Portland State University Ph.D. candidate, will be awarded a $15,000 fellowship to support her doctoral dissertation research.

Goddard's dissertation explores drivers' behaviors toward bicyclists in roadway interactions.

Bicyclists in the United States are twelve times more likely than car occupants to be killed in a traffic crash with a car. Existing research into crash causation has focused on physical factors such as vehicle speed and intersection type, with little of it delving into psychological and cultural variables.

Goddard is researching drivers' attitudes toward bicyclists, by means of an online survey, in an effort to understand how those attidutes may predict behaviors. She hopes to reveal some of the underlying causes of bicycle and motor vehicle collisions.

Her research aims to advance community livability and safety goals.

A new NITC project has developed a robust pedestrian demand estimation tool, the first of its kind in the country.

Using the tool, planners can predict pedestrian trips with spatial acuity.

The research was completed in partnership with Oregon Metro, and will allow Metro to allocate infrastructure based on pedestrian demand in the Portland, Oregon metropolitan area.

In a previous project completed last year as part of the same partnership, the lead investigator, Kelly Clifton, developed a way to collect data about the pedestrian environment on a small, neighborhood scale that made sense for walk trips. For more about how that works, click here to read our news coverage of that project. 

Following the initial project, the next step was to take that micro-level pedestrian data and use it to predict destination choice. For every walk trip generated by the model in the first project, this tool matches it to a likely destination based on traveler characteristics and environmental attributes.

Seven Oregon Tech students attended a sustainable pavement conference in Portland thanks to NITC program funding. The 2015 Asphalt Sustainability Conference West highlighted innovations in technologies and practices.

Danit Hubbell, Oregon Tech’s ITE student chapter president, said she and the other students who made the trip last month are all transportation focused, though they have varying degrees of interest in asphalt. The conference featured a good mix of topics, she said.

The term “sustainability” can vary based on context, and that was reflected in the conference sessions, Hubbell said. “One presenter talked about it as the asphalt itself and the materials it’s made out of. For others, it was the transportation and the longevity.

“I think it encompasses both of those,” she said.

Asphalt paving has come a long way in the last few years, Hubbell said, with sustainability driving much of the changes. Oregon Tech has stayed on top of those innovations, she said, as all civil engineering students must complete a infrastructure sustainability course.

The conference seemed to draw more transportation practitioners than students, Hubbell said, which was part of its appeal. The Oregon Tech students relished the opportunity to browse the exhibitors’ tables and talk with professionals from various organizations.

Hubbell, who graduates next March, already has a job lined up. She’ll join Kiewit Infrastructure...

Portland State University today achieved the highest ranking from the League of American Bicyclists' Bicycle Friendly University program. Portland State is now one of just five platinum universities recognized under the program.

Other NITC program campuses were also designated as bike friendly. University of Oregon achieved gold status and University of Utah, silver.

The Bicycle Friendly University program evaluates applicants’ efforts to promote bicycling in five primary areas: engineering, encouragement, education, enforcement and evaluation/planning, known as the Five E's.

The league noted that Portland State’s support for bicycling has helped reduce congestion, improve air quality and lower the demand for parking on campus. “Portland State encourages bicycling as an affordable, efficient option for transportation and provides amenities such as indoor bicycle parking, low-cost bicycle rentals, and an on-campus Bike Hub, where students can find everything they need to make bicycling a part of their commute options,” the league stated.

PSU previously was a gold-level bike-friendly university. In the past two years it expanded its “Vik Bike” bicycle rental program from 12 bicycles to 134. Each bike comes with lights, a lock and a helmet. The program, in which students can rent a bike for a term, receive training on bike commuting and bike maintenance, has a waiting list of participants.
