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 ...

OTREC researchers will present on bike/ped counts at traffic data conference

Jun 26, 2014

OTREC researchers Krista Nordback and Sirisha Kothuri will present research at the North American Travel Monitoring Exposition and Conference (NATMEC) from June 29 to July 2, 2014.

The conference, organized by the Transportation Research Board, provides an opportunity for traffic monitoring professionals to share information about collecting and using traffic data.

Nordback will talk about what professionals can do to maintain bicycle count programs at the state level. She will give a presentation on the feasibility of using existing traffic signals to collect bicycle counts, and on what to do with that data once it is gathered.

Kothuri will present strategies for counting pedestrians using existing resources such as signal controllers and software already installed at intersections.

Nordback and Kothuri will draw from their own research as well as from the work of Miguel Figliozzi, Chris Monsere, ...

U.S. DOT assistant secretary tours Portland

Jun 16, 2014

Bicycle and pedestrian safety has emerged as a top priority for U.S. Transportation Secretary Anthony Foxx and the Department of Transportation. With this in mind, the department’s top research official visited Portland State University, home to the U.S. DOT-designated national center for livable communities.

Greg Winfree, the assistant secretary for research and technology, visited Portland State’s transportation research and education center June 13. Center Director Jennifer Dill and researcher Christopher Monsere gave Winfree a tour of the center’s living laboratory: Portland’s active transportation infrastructure.

Winfree, an advocate for improving safety for vulnerable road users, explored the city’s various bicycle safety efforts, including bike boulevards, protected bike lanes, bike boxes, bike-specific signals and signage. He also learned of pedestrian research involving traffic signals, crossings and...

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...

New Modeling Tools Better Represent the Pedestrian Environment

Apr 25, 2014

OTREC research from Portland State University has developed a new method of travel demand modeling for pedestrian trips.

Transportation professionals use travel demand modeling to forecast how many people will be using a given portion of the transportation infrastructure. This is typically done using a four-step process, the first step of which relies upon a basic unit known as a transportation analysis zone, or TAZ.

A TAZ is a relatively coarse unit of space that can vary in size depending on planners’ needs; typically it encompasses somewhere around 3,000 residents.

Planners started using TAZs in the 1950s, on mainframe computers with limited capabilities, for guidance in making highway investment decisions. As transportation modeling practice has evolved, computers are capable of processing more data and models are being increasingly relied upon to answer more complex questions.

Despite growing investment in infrastructure that supports active forms of travel, existing modeling tools often poorly represent the nuances of the pedestrian environment. The project’s principal investigator, Kelly Clifton of Portland State University, explores ways to improve upon the modeling tools currently in existence.
