PSU students help determine Cully neighborhood's walkability needs

Jul 11, 2014

Three Portland State University graduate students in the Nohad A. Toulan School of Urban Studies and Planning used GIS technology to collect and analyze residents’ thoughts about walkability needs for Portland, Oregon’s northeast Cully neighborhood.

Their report, Engaging Cully, was the final product of a ten-week course called Public Participation Geographic Information Systems (PPGIS), taught by PSU professor Vivek Shandas.

In PPGIS, community input is used to create GIS-based data and diagnostics maps which can inform planners’ decision-making process. Team members Travis Driessen, Brandi Campbell and Eduardo Montejo worked with community-based organizations and residents to assess the needs of the Cully neighborhood’s pedestrian network using PPGIS methods.

Prior to this project, Driessen, who is working toward a graduate certificate in Geographic Information Systems at PSU, was already collaborating with David Hampsten, a board member of the Hazelwood Neighborhood Association and member of the East Portland Action Plan, to help Prioritize Portland! – a coalition consisting of multiple organizations including the Northeast Coalition...

Emerging field of HIA helps to assess the public health impact of future plans

Jul 11, 2014

New research from NITC looks at Health Impact Assessment, or HIA, in transportation planning.

The leading causes of death in the United States are no longer communicable diseases. Instead, chronic conditions linked to behaviors and shaped by environments—such as obesity and diabetes—are today’s most pressing public health concerns.

HIA is a way of evaluating the effects that planning decisions will have on public health.

Researcher Nicole Iroz-Elardo studied this relatively new endeavor, analyzing and comparing three contemporary case studies in HIA.

She will share her findings in an IBPI webinar on July 16, 2014.

By engaging professionals from multiple disciplines, HIA can give planners a larger knowledge base to inform decisions.

In a collaborative process that did not emerge in the U.S. until 1999, stakeholders and community members engage with public health professionals to identify and deliberate about health interests related to the proposed plan.

They generally focus on health equity, and use as a framework the social determinants of health: a broad range of factors developed...

OTREC research examines ways to anonymize location data

Jul 07, 2014

A new OTREC report explores an innovative technique for making household travel data more widely available without compromising individual privacy.

Public agencies spend vast amounts of money collecting information in household travel surveys.

In the report, Wider Dissemination of Household Travel Survey Data Using Geographical Perturbation Methods, lead investigator Kelly Clifton of Portland State University examines ways to make that information more accessible by planners and other professionals.

Survey respondents are guaranteed anonymity in exchange for their participation. In addition to asking which modes individuals use to get around, surveys learn where they live, where they work, their household sizes and demographic information.

Detailed geospatial referencing of the home, work and other travel destinations is common practice.

Such data can be of enormous use to planning professionals, but its dissemination must be balanced with the need to keep locations confidential.

To protect this confidentiality, data are often aggregated to a geographic level such as census tracts or transportation analysis zones (TAZs) before being publicly shared.

Portland State University students enhance Tigard's walkability

Capstone students take on transportation challenges

Jun 18, 2014

Five teams of Portland State University seniors worked on projects in the transportation arena, as the final outcome of their Capstone course.

The transportation Capstone projects were completed under the advisement of Dr. Robert Bertini, a professor of Civil and Environmental Engineering at Portland State University and OTREC’s founding director.

Senior Capstone projects in engineering are about more than just technical aspects of design. They are an opportunity for students to meet with clients and consult with professionals, to develop the communication and collaboration skills which will be necessary in future careers.

John Edwards, a student team leader, described the project as a great opportunity. “We learned a great deal about project management and communication in working with professionals,” Edwards said.

In each project, students met with clients under the guidance of faculty to come up with solutions to problems that the clients were facing.

A group led by Krista Hager worked on a concept design for bicycle parking at the Goose Hollow eastbound MAX Station in southwest Portland, Ore.

The existing grade conditions and the...

PSU student team finds transit solutions for Salem-Keizer

Jun 16, 2014

Portland State University students in the Master of Urban and Regional Planning (MURP) program came up with some innovative transit solutions for the Salem-Keizer area, just south of Portland, Ore. in the Willamette Valley.

The Salem-Keizer transit provider, known as Cherriots, requested that a planning group come up with alternative forms of transit that would be a better fit for the study area. MURP students Darwin Moosavi, Brenda Martin, CJ Doxsee, Mike Sellinger, Lauren Wirtis and Matt Berggren took on the challenge as their capstone project.

The bus service currently provided by Salem-Keizer Transit is inefficient in the low-density neighborhoods of West Salem, South Salem, and Keizer. Buses in those neighborhoods often run half-full, or nearly empty, along looping, circuitous roads that lack an interconnected grid pattern.

The student team, Paradigm Planning, proposed a “flexible transit” system which can better serve this type of low-density suburban area.

Fixed-route transit is typical bus service, in which buses come to predefined stops at regularly scheduled intervals. Demand-responsive or paratransit, the opposite extreme, is an on-demand service typically reserved for the elderly or disabled, in which a rider calls to be picked up by a bus at...

Capstone course promotes community partnerships with Green Streets

Jun 11, 2014

On Saturday, May 31, Green Street Stewards of Portland, Ore. held a block party to celebrate and foster community partnerships.

Green Street Stewards are community members who have volunteered to help support and maintain Portland’s Green Streets, a program that was started in 2003 by the Bureau of Environmental Services (BES) as an environmentally friendly way to manage stormwater runoff.

Green Streets facilities are streetside planters or gardens that capture runoff and feed it into rivers and streams, taking advantage of the natural ability of soil and vegetation to filter out pollutants.

To galvanize community support and raise awareness about the program, the Stewards partnered with a capstone course taught by Thaddeus Miller, an assistant professor in the Toulan School of Urban Studies & Planning. As part of her capstone project, Portland State University student Taylor Balakrishnan helped organize the block party.

"It was really good for us to gain some experience planning an event like this, and to see a positive outcome,” Balakrishnan said.

The block party was held in the Lents Park area, a neighborhood of southeast Portland. The event’s partners included the City of Portland’s BES...

Policymakers meet with youth for discussion on transit justice

May 27, 2014

The Multnomah Youth Commission, or MYC, held its first Youth Summit on Transit Justice on May 17, 2014 at David Douglas High School.

The MYC, a group of young people ages 13-21, plays an advisory role for local government in Multnomah County and the City of Portland.

The summit held on Saturday the 17th was an entirely youth-led event, with members of the MYC meeting at David Douglas at 11 a.m. After they spent the morning organizing their materials and preparing their arguments, they opened the doors for adults.

PSU professor Lisa Bates, who is studying the transit-dependent population for NITC, was in attendance with her capstone students. As part of a capstone course where students are required to conduct research that leads directly into social equity, Bates’ students worked with the youth of the MYC on transit justice. They applied a social science research foundation to their ideas and assisted them with using some best practices in the field.

At 2:30 p.m., transit policymakers and community leaders began to enter the high school. Following a brief introductory presentation, the young people split up the group into breakout sessions.

During the sessions, members of the...

Study examines racial bias at crosswalks

May 20, 2014

In a pilot study funded by the NITC Small Starts program, researchers explored whether drivers behave differently toward pedestrians waiting to use a crosswalk based on the pedestrian’s race. The study – the first examining the effects of race on pedestrian crossing experiences – found that black pedestrians were passed by twice as many cars and waited nearly a third longer to cross than white pedestrians.

Minorities are disproportionately represented among pedestrian fatalities in the United States. The Center for Disease Control reported in 2013 that in the first decade of this century, the fatality rates for black and Hispanic men were twice as high as they were for white men.

Researchers Kimberly Barsamian Kahn and Tara Goddard of Portland State University, and Arlie Adkins, of the University of Arizona, hypothesized that if minority pedestrians experience more delay at crosswalks, they might take greater risks when crossing – risks that could contribute to the disparate fatality rates.

Kahn, an assistant professor of social psychology, studies contemporary forms of racial bias that are hidden within society. Working with Goddard and Adkins, who were interested in the social equity impacts of transportation, Kahn put together a controlled field experiment to measure...
