John Pucher (Professor Emeritus, Rutgers University) passes along this lead editorial on cycling in the new December 2016 issue of the American Journal of Public Health. “Table 1 should be especially interesting, as it compares trends in cycling infrastructure, cycling levels, and cycling safety in 10 US cities.”
A study of different kinds of cycling facilities in Vancouver and Toronto, Canada, found that the safest kind of facility, by far, were cycle tracks, which are on-street bicycle lanes that are physically separated from motor vehicles by raised curbs, bollards, or concrete barriers.
Compared with major streets with parked cars and no bicycle facilities, cycle tracks on roads without parked cars were 89% safer; regular, unprotected bicycle lanes on major roads without parked cars were 53% safer; and lightly trafficked residential streets without any bicycle facilities were 56% safer. Thus, removing car parking and replacing it with cycle tracks is an ideal way to improve cycling safety on major streets
