Background: Cycling is an important recreational activity and mode of transportation in the City of Vancouver. However, traumatic crashes involving cyclists can lead to serious injuries or fatalities, particularly when collisions with automobiles occur. The purpose of this study was to determine specific high-risk cycling areas within the City of Vancouver and the severity of injuries at these locations. Methods: Data on the frequency of collisions involving cyclists over the study period were mapped across Vancouver to identify trends of injury as associated with time of day, day of the week, likelihood of commuting, seasonality, lighting and bicycle lane use. Additionally, BC Trauma Registry (BCTR) data were used to quantify the severity of injury. Results were also linked with community survey data to assess perceptions and reported frequency of cycling. Results: Over 2300 bicycle collisions were reported between April 2012 and March 2017 in the City of Vancouver. Twenty-three high-risk intersections were also identified with collision counts ranging from 7 to 26. A majority of collisions at these sites occurred at evening commute times, during the day and in the summer. The severity of crashes increased during dusk and dawn and when there was a greater patient count. Additionally, results from the community survey indicate that the majority of collisions occurred in areas where residents reported having amenities within cycling distance, having many lanes for cyclists, less commuting and errand running by automobile and seeing regular visible cyclists. Conclusion: Given this analysis, potential interventions will be tailored for the 23 high-risk intersections and will be prioritized by the research team in collaboration with the City of Vancouver to identify the viability of implementation. For example, creating new bike lanes, connecting disjointed bike lanes, changing speed limits to 30 km/h and promoting safe practices within bicycle rental stores are plausible interventions.
