A study of 167 European cities suggests that up to 10,000 premature deaths could be avoided annually if cities provided sufficient infrastructure and 1 in every 4 citizens used bicycling as their primary mode of transportation. Premature deaths would be prevented through improved air quality, public health benefits, and collision reduction.
