Summary: Researchers from the transportation, planning and health fields share the common goal of promoting physically active lifestyle. One challenge that researchers often face is the measurement of physical activity, particularly among children. This is because the sporadic nature of children’s physical activity patterns makes it difficult to recall and quantify such activities. Additionally, children’s lower cognitive functioning compared to adults prevents them from accurately recalling their activities. This presentation will describe the design and application of a novel self-report instrument - the Graphs for Recalling Activity Time (GReAT) - for measuring children’s activity time use patterns. The instrument was applied in a study of children’s risk for obesity and diabetes in a predominately Hispanic community in Milwaukee, WI. Time-use data for two weekdays and one weekend day were collected for various physical and sedentary activities. The data was then assessed against measurements of the children’s cardiovascular fitness, weight status and insulin resistance through exploratory analysis and structured equation modeling. Findings on GReAT’s reliability and new evidence on the impacts of time-use in...

Joseph Broach, PhD candidate in Urban Studies, will discuss the results of his research, which models the propensity of children aged 6-16 to walk or bike to parks and school without an adult chaperone, extending existing work on children’s active travel in several ways: 1) focus on travel without an adult, 2) inclusion of school and a non-school destinations, 3) separate walk and bike models, 4) consideration of both parent and child attitudes and perceived social norms, 5) explicit inclusion of household rules limiting walking or bicycling.

Speaker: Brian Saelens, Professor of Pediatrics and Psychiatry & Behavioral Sciences, Seattle’s Children’s Hospital & University of Washington
Topic: Links Between Public Transportation and Physical Activity (Effects of LRT on Physical Activity Based on Seattle GPS Study)

Summary: This seminar will explore the empirical evidence regarding the links between the use of public transportation and physical activity, with a specific focus on using integrated device and self-report methods to identify travel modes and physical activity.

Bio: Brian E. Saelens, Ph.D. is a Professor of Pediatrics and Psychiatry & Behavioral Sciences at the University of Washington and Principal Investigator at Seattle Children’s Research Institute. Dr. Saelens is a clinical/health psychologist. His interest areas include obesity treatment and prevention, especially in environmental factors and policies that influence physical activity and eating behaviors in children and adults. He has published over 150 peer-reviewed original investigation and review articles.

Speaker: Joseph Broach, Ph.D. Candidate, Portland State University
Topic: Trick or Treatment? Impact of Route-Level Features on Decisions to Walk or Bike
Summary: Some travel routes attract people walking and cycling, while others may scare them away. What features of street environments are most important, and how do available routes affect decisions to bike or walk on a specific trip? 

Research to date has focused on either large-scale areal measures like "miles of bike lane nearby" or else has considered only shortest path routes. Neither method is suited to capturing the impact of targeted route-level policies like neighborhood greenways. This session will present a new technique for measuring bike and walk accessibility along the most likely route for a given trip. The method is applied to travel data, and results provide new insight into the relationship between route quality and travel mode choice.

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...

The executive committee of the National Institute for Transportation and Communities, or NITC, program has selected a third round of research, education, and technology transfer projects for funding. This grant is part of the University Transportation Center (UTC) program funded by the U.S. Department of Transportation’s Office of Research and Technology, and is a partnership between Portland State University, the University of Oregon, the Oregon Institute of Technology, and the University of Utah. The committee chose eight projects, totaling $800,000, under the NITC theme of safe, healthy and sustainable transportation to foster livable communities. 
 
The projects are national in scope and support innovations in priority areas including public transit and active transportation. 
 
Projects selected include:
  • An analysis of the effects of commuter rail on population deconcentration.
  • A look into prioritizing pedestrians at signalized intersections.
  • A study of cyclist-vehicle interaction.
  • An evaluation of an eco-driving intervention.
The eight projects were chosen from among 20 proposals...

Several notable transportation projects have come out of Portland State University’s Master of Urban and Regional Planning (MURP) program this spring.

 

Each year, graduating students finish up their two-year program of study by forming into groups and carrying out a professional project. Clients work with Portland State University to identify planning needs that would be a good fit for the MURP program, and students choose projects based on their interests.

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, Pam Johnson and...

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 modeling

The tour highlighted research projects funded through U.S. DOT...
