Objectives:
The purpose of this study was to estimate children's exposure to traffic (number of streets crossed) and to determine the role of exposure in pedestrian injury.
Methods:
Questionnaires were distributed to a random sample of 4080 first- and fourth-grade children in 43 Montreal schools.
Results:
When analyzed by police district, injury and exposure rates were positively correlated (r2 = 0.53). Crossings were similar by sex but increased with age and were inversely related to socioeconomic status.
Conclusions:
These results suggest that although children's exposure to traffic could be reduced by transporting them to school, a more reasonable prevention strategy involves environmental changes.
