A disaggregated analysis of environmental factors associated with the number of children injured by motor vehicles in urban settings 
This research analyzes the number and geographic distribution of children injured by motor vehicles in urban settings as well as the association with recognized environmental factors such as traffic volume and street geometry. The sample includes 6,775 children (5 to 17 years old) injured on the Montreal road network between 1999 and 2008. Results show that, in both the poorest and the wealthiest neighbourhoods, about half of the children were injured at intersections with high traffic volume or on major arterial roads. The mean number of young pedestrians injured was 39 times greater at intersections with high traffic volume (5th quintile) compared to intersections within the 1st quintile. Locally weighted least square regression analyses show variations in the effect of traffic volume across central boroughs with a similar number of children per square kilometer.
