Severity of urban cycling injuries and the relationship with personal, trip, route and crash characteristics : analyses using four severity metrics Cripton, Peter Alec, 1965-; Shen, Hui; Brubacher, Jeffrey; Chipman, Mary; Friedman, Steven M.; Harris, M.

Objective: To examine the relationship between cycling injury severity and personal, trip, route and crash characteristics. Results: Older age and collision with a motor vehicle were consistently associated with increased severity in all four metrics and statistically significant in three each (both variables with ambulance transport and CTAS; age with hospital admission; and motor vehicle collision with did not continue by bike). Other factors were consistently associated with more severe injuries, but statistically significant in one metric each: downhill grades; higher motor vehicle speeds; sidewalks (these significant for ambulance transport); multiuse paths and local streets (both significant for hospital admission). Conclusions: In two of Canada's largest cities, about one-third of the bicycle crashes were collisions with motor vehicles and the resulting injuries were more severe than in other crash circumstances, underscoring the importance of separating cyclists from motor vehicle traffic. Our results also suggest that bicycling injury severity and injury risk would be reduced on facilities that minimise slopes, have lower vehicle speeds, and that are designed for bicycling rather than shared with pedestrians.
