Upcoming roundtable sponsored by the Food and Nutrition Board at the
National Academies of Sciences, Engineering and Medicine.

How can investments in the built environment advance obesity
12*, join the Roundtable on Obesity Solutions for a workshop that will
explore the roles built environment policies and practices play in the
prevention and treatment of obesity and will highlight promising, scalable,
multi-sector strategies to create more healthful and equitable
environments. Built environment topics that will be covered include urban
planning and design, transportation systems, parks and recreation, and food
systems. Register to attend either in person or via webcast. Due to seating
capacity, in-person registration for this workshop is limited.
We recently published an article on using an agent-based modeling framework to study population exposure to traffic-related pollution and issues pertaining to environmental justice and data-resolution. I thought this article may be of interest to the members of this group. Please find it attached (I provided the link below if you want to directly access it on the journal website):
Some key highlights of the article:
* We developed an exposure modeling framework by integrating an activity-based travel demand model (DaySIM), a dynamic traffic assignment model (MATSim), a mobile source emissions model (EPA MOVES), and a dispersion model (RLINE)
o This framework was used to estimate human activities, roadway link-level emissions, concentrations on a 500 meter grid, and exposure to NOx at the person-level and population subgroup-level
* The study area is Hillsborough County, Florida (Tampa)
* Below poverty group, blacks, working adults, and individuals with longer travel times had disproportionately high exposures
* Exposure disparities for minorities increased sharply at higher exposure levels
* Use of low-resolution activities and concentration data underestimated exposures on average
o This underestimation of exposure is more pronounced with the use of just low-resolution concentration data as opposed to the use of just low-resolution activity data; this suggests use of high-resolution concentration data may be more important than use of high-resolution activity data to estimate exposures

For those with an interest in integrating public health and transportation for better health and safety outcomes, please consider the upcoming event in April. There's still time to submit a poster idea (by February 15), with community projects welcome and the poster competition will offer cash prizes for students (1st place = $500, 2nd place = $350, 3rd place = $150).
Register today for the Safe Systems Summit: April 23-24, in Durham, NC
The Safe Systems Summit: Redefining Transportation Safety<https://www.roadsafety.unc.edu/profdev/summit/> offers an inclusive and interactive learning environment to explore the underlying systems driving the national rise in traffic deaths, share findings from innovative new research, and develop insights into reducing transportation injuries and fatalities by utilizing both Safe Systems <https://www.roadsafety.unc.edu/about/safesystems/> and systems science principles, tools, and techniques. Join participants from various disciplines to explore systems together, discuss advanced and emerging technologies and the role of data integration, and exchange ideas with national and international experts. Leave with new ideas, connections, resources, and skills. Register by March 29 and take advantage of low registration costs ($35 for participants, $20 for students).
The Summit is hosted by the Collaborative Sciences Center for Road Safety<https://www.roadsafety.unc.edu/> and co-sponsored by the North Carolina Governor's Highway Safety Program<https://www.ncdot.gov/programs/ghsp/>. Learn more about the program<https://www.roadsafety.unc.edu/summit/safe-systems-summit-agenda/>, and submit your poster<https://www.roadsafety.unc.edu/summit/poster-details/> idea by February 15.
