The new standards call for reduced speeds within the school zone, which is identified as the school property boundary and all streets and intersections adjacent to the school property. This area is unique in that there is a heavy mix of pedestrian activity with vehicles traveling to and from the school during a narrow window of time.
Reducing the speed on a street that is not adjacent to a school is proven to be less effective in slowing vehicles. Because of this, a mix of vehicles traveling at speeds that are significantly different in speeds from one another creates an increase in safety issues as compared to streets where all vehicles travel at speeds in close magnitude to each other.
