Abstract
Safe urban walking environments may improve health by encouraging physical activity, but
the relationship between an individual's location and walking pattern and the risk of
pedestrian-motor vehicle collision is unknown. We examined associations between
individuals' walking bouts and walking risk, measured as mean exposure to the risk of
pedestrian-vehicle collision. Walking bouts were ascertained through integrated
accelerometry and global positioning system data and from individual travel-diary data
obtained from adults in the Travel Assessment and Community Study (King County,
Washington) in 2008-2009. Walking patterns were superimposed onto maps of the historical
probabilities of pedestrian-vehicle collisions for intersections and midblock segments
within Seattle, Washington. Mean risk of pedestrian-vehicle collision in specific walking
locations was assessed according to walking exposure (duration, distance, and intensity)
and participant demographic characteristics in linear mixed models. Participants typically
walked in areas with low pedestrian collision risk when walking for recreation, walking at
a faster pace, or taking longer-duration walks. Mean daily walking duration and distance
were not associated with collision risk. Males walked in areas with higher collision risk
compared with females, while vehicle owners, residents of single-family homes, and parents
of young children walked in areas with lower collision risk. These findings may suggest
that pedestrians moderate collision risk by using lower-risk routes.

Transportation and Land Use as Social Determinants of Health: Analysis of Exposure to
Traffic in the Denver Metropolitan Region
http://www.ugpti.org/resources/reports/downloads/mpc17-326.pdf
The report examines residential exposure to traffic at the regional and neighborhood
levels while incorporating the impacts of race and socioeconomic status. The study focused
on how transportation and land use may influence residents' exposure to traffic and
adverse health outcomes.
