Guest Lecturer James Woodcock, UK Clinical Research Collaboration

Modeling is the simulation of a partial representation of a system. It can help us answer questions that no single empirical study can answer. Modeling enables us to estimate longer term and population wide health effects of interventions, integrate evidence from different domains, consider hypothetical ‘what if’ scenarios, and address issues of cost and cost-effectiveness. Modeling can also be used to investigate how health related practices might change in complex systems.

Modeling studies can be cheaper and quicker than real-world studies and do not require the intervention to actually be implemented. They can therefore support getting the best value from intervention studies and natural experiments. In public health modeling at the UKCRC Centre for Diet and Activity Research (CEDAR), evidence from many different primary studies is used plus insights from experts and other stakeholders. Simulation of models containing uncertainty can be used to indicate where the gaps in knowledge are most critical for decision making.

This lecture will describe the UK Clinical Research Collaboration's approach to modeling the health impacts of transportation decisions. 

TREC is hosting this event, in partnership with the Oregon Health Authority.

Cycling is currently a hotly debated political and policy issue, especially in relation to safety. While research has studied serious injuries and deaths, this project targets a more common, yet under-researched phenomenon: the ‘ordinary’ experience of near misses and other non-injury incidents (from incivilities and low-level harassment to SMIDSY: ‘sorry mate, I didn’t see you’).

Near miss and related incidents are common, according to a pioneering study in Oxford in the early 1990s. More recent work in Middlesex suggests close passes (under 50cm) may happen with predictable regularity for commuting cyclists, while an Australian study highlights experiences of deliberate abuse and harassment.

Yet apart from this work, there remains little research into non-injury incidents. We don’t know, for example, how often they happen to UK cyclists, and how this varies. This is a substantial missed opportunity, both to improve people’s experiences of cycling, and to use our knowledge of near misses to prevent injuries. The latter is commonplace in other areas of transport such as rail and air but near-absent for cycling.

This lecture will introduce the Near Miss project, which seeks to research, analyze and document cycling near misses, and contribute to training drivers and transport professionals. It will...

Alex Bigazzi, a 2014 NITC dissertation fellow and graduate of Portland State University's Civil and Environmental Engineering Ph.D. program, has published a paper based on his NITC-funded research in Environmental Science & Technology, a journal of the American Chemical Society (ACS).

See ACS coverage of the project here.

Bigazzi's research evaluates the concentration of air pollution encountered by cyclists in Portland, Oregon.

In the study, volunteer research subjects rode bicycles equipped with instruments to collect high-resolution bicycle, rider, traffic and environmental data.

Participants rode a variety of routes including bicycle lanes on primary and secondary arterials, bicycle boulevards, off-street paths and mixed-use roadways. They were told to ride at a pace and exertion level typical for utilitarian travel, and breath biomarkers were used to record the amount of traffic-related pollution present in each cyclist’s exhalations. 

This research was the focus of Bigazzi's dissertation, Bicyclists’ Uptake of Traffic-Related Air Pollution: Effects of the Urban Transportation System, published by NITC in December 2014. It was related to an earlier project...

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...

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.

The researchers focused...

GPS use in travel behavior studies has seen increasing acceptance over the past decade, with more than 15 travel surveys conducted since 2000 including a GPS subcomponent. Similarly, accelerometers have become the gold standard for collecting objective physical activity data in health studies. Since 2003, GeoStats has been involved in studies that have deployed both devices in tandem to collect second-by-second travel and physical activity data never before available. This seminar will cover the use of these technologies to address key research questions facing transportation and health professionals.

Dr. Jean Wolf is the president and co-founder of GeoStats, a company specializing in the application of GPS and GIS technologies for the collection, analysis, visualization, and reporting of transportation data. Since the launch of GeoStats in 2000, Dr. Wolf has led all GPS-enhanced travel surveys and physical activity studies conducted by the firm (with more than 20 studies to date). Dr. Wolf has extensive project management, technology, and logistics experience, including 10 years at UPS as an industrial and systems engineer, which makes her uniquely qualified to run complex GPS studies that depend upon the integration of numerous processes and data flows to produce highly detailed and accurate GPS deliverables. Dr. Wolf is a member of the TRB Travel Survey Methods Committee...
