Portland State University

Despite the many connections between transportation and public health, many agencies tasked with long-range transportation planning have yet to completely consider effects on health, a Portland State University research team found. The research will be presented at the annual meeting of the Transportation Research Board in Washington, D.C. Jan. 11-15.

Patrick Singleton, a Portland State graduate student researcher, will present the paper “Incorporating public health in U.S. long-range metropolitan transportation planning: A review of guidance statements and performance measures,” during a poster session Tuesday. The paper grew out of concepts developed in a Portland State course on transportation and health taught by Prof. Kelly Clifton, who is a coauthor on the paper.

Individually, transportation and public health each have a wealth of research. That research doesn’t always cross over, Singleton said.

“The integration of these disciplines is in its infancy,” he said.

If transportation planning agencies were to fully consider transportation and health connections, those considerations would show up in their long-term plans, the research team reasoned. Performance measures would point to the potential effects of a health focus.

Active travel such as walking and bicycling can lead to health benefits through an increase in physical activity. At the same time, more active travelers breath more and so can experience high pollution inhalation rates during travel. This webinar will review the state of knowledge about how roadway and traffic characteristics impact air pollution risks for bicyclists, including the latest PSU research quantifying bicyclists' uptake of traffic-related air pollution using on-road measurements in Portland. The PSU research team including Alex Bigazzi, Jim Pankow, and Miguel Figliozzi quantified bicyclist exposure concentrations on different types of roadways, respiration responses to exertion level, and changes in blood concentrations of pollutants. Implications for planners, engineers, and policy-makers will be discussed, including guidance for more pollution-conscious bicycle network planning and design. Additionally, ways for individual travelers to reduce their air pollution risks will be discussed.

This 60-minute webinar is eligible for one hour of training which equals 1 CM or 1 PDH. NITC applies to the AICP for Certification Maintenance credit for each webinar. We will provide an attendance certificate...

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 different activities on children’s risk for...
