The Geographical Sciences Committee of the National Academies of Science, Engineering and Medicine has posted a recording of my 1 March 2017 webinar on “Using GIS to Make Urban Mobility More Sustainable.” Thanks to the GSC for sponsoring and hosting this event!
Brown, B.B., Tharp, D., Tribby, C.P., Smith, K.R., Miller, H.J., Werner, C.M. (2016) ‘Changes in bicycling over time associated with a new bike lane: Relations with kilocalories energy expenditure and body mass index,” Journal of Transport and Health, 3, 357-365.
- We tracked bicycling activity over two years using accelerometers and GPS loggers.
- Any cycling relates to more calories burned but not lower BMI.
- Cyclists burn more calories on their cycling days than on their non-cycling days.
- Cyclists burn more calories than non-cyclists, even on non-cycling days.
- Greater use of a urban bike lane related to lower BMI and more calories burned.
Although bicycling has been related to positive health indicators, few studies examine health-related measures associated with non-competitive community cycling before and after cycling infrastructure improvements. This study examined cycling changes in a neighborhood receiving a bike lane, light rail, and other “complete street” improvements. Participants wore accelerometers and global positioning system (GPS) data loggers for one week in both 2012 and 2013, pre- and post-construction completion. Participants sampled within 2 km of the complete street improvements had the following patterns of cycling: never cyclists (n=434), continuing cyclists (n= 29), former cyclists (n=33, who bicycled in 2012 but not 2013), and new cyclists (n=40, who bicycled in 2013 but not 2012). Results show that all three cycling groups, as identified by GPS/accelerometry data, expended more estimated kilocalories (kcal) of energy per minute during the monitoring week than those who were never detected cycling, net of control variables. Similar but attenuated results emerged when cycling self-report measures were used. BMI was not related to cycling group but those who cycled longer on the new path had lower BMI. Although cyclists burn more calories than non-cyclists across the week, among cyclists, their cycling days involved more calories expended than their non-cycling days. The new cyclists account for 39% of the cyclists identified in this study and former cyclists account for 32% of cyclists. These results suggest that cycling is healthy, but that sustaining rates of cycling will be an important goal for future policy and research.
The Center for Urban and Regional Analysis (CURA) is pleased to welcome Samuel Schwartz to Ohio State University for a free public lecture on Tuesday, September 20, 2016, 4:00pm at the Wexner Center Film/Video Theater, 1871 N. High Street, Columbus, OH 43210
Sam Schwartz is the most famous traffic engineer in the world, serving as New York City Transportation Commissioner under several mayors, and now leads an international and highly influential consulting firm, Sam Schwartz Engineering. Mr. Schwartz invented the word ‘gridlock,’ earning the enduring moniker “Gridlock Sam.”
Sam is called the “Jane Jacobs of Traffic” due to his long fight to create room for humans and social space in city streets and an “urban alchemist” for his uncanny ability to grow green space from asphalt. In Canada, is he known as “[The] Wayne Gretzky of Traffic Planning.”
Gridlock Sam will speak about his recent book, Street Smart: The Rise of Cities and Fall of Cars, a lively history and discussion of how to move cities beyond automobile dominance.
The lecture is free and open to the public, but space is limited, so RSVP today at: http://cura.osu.edu/920rsvp
