Preliminary data suggests that the addition of crossing guards to school environments may lead to increased rates of children's active transportation.  During the 2011-2012 school year, CDC Communities Putting Prevention to Work funds hired new crossing guards for the City of Miami schools. The purpose of this project was to determine if an increase in crossing guard presence is associated with an increase in the number of children walking and biking to school in 10 elementary schools in Miami, FL.  Type and amount of physical activity was measured through counts conducted at intervention and control intersections at pre- and post-data collection.  Parental attitudes towards allowing their children to utilize active travel and their perceptions of safety was assessed through the Safe Routes to School Parent Survey.
