The Relationship Between Objectively Measured Walking and Risk of Pedestrian-Motor Vehicle Collision. American Journal of Epidemiology, 185(9), 810-821. doi: 10.1093/aje/kwx020 https://academic.oup.com/aje/article/doi/10.1093/aje/kwx020/3058755/The-Rel… 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. -----Original Message----- From: h+t--friends-bounces(a)chrispy.net [mailto:h+t--friends-bounces@chrispy.net] On Behalf Of h+t--friends-request(a)chrispy.net Sent: Friday, July 28, 2017 1:00 PM To: h+t--friends(a)chrispy.net Subject: H+T--Friends Digest, Vol 75, Issue 3 Send H+T--Friends mailing list submissions to h+t--friends(a)chrispy.net To subscribe or unsubscribe via the World Wide Web, visit https://www.chrispy.net/mailman/listinfo/h+t--friends or, via email, send a message with subject or body 'help' to h+t--friends-request(a)chrispy.net You can reach the person managing the list at h+t--friends-owner(a)chrispy.net When replying, please edit your Subject line so it is more specific than "Re: Contents of H+T--Friends digest..."

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. -- Ed Christopher Transportation Planning Consultant 708-269-5237 ------------------------------ _______________________________________________ H+T--Friends mailing list H+T--Friends(a)chrispy.net https://www.chrispy.net/mailman/listinfo/h+t--friends End of H+T--Friends Digest, Vol 75, Issue 3 *******************************************
