Developing a Measure of Traffic Calming Associated with Elementary School Students' Active Transportation

This study developed a measure of traffic calming highly correlated with active travel to school that could be used to inform policy and planning decisions.


  • The measure included five features gathered from GIS data as characteristics of streets with traffic calming: intersection density, medians/dividers, low mobility streets, roundabouts, and street parking availability.
  • In the model created by this study, these characteristics of traffic calming explained 86% of the variability in active transport to school.


  • This study used administrator-reported estimates of walking and biking to school in a nationally representative sample of schools from 2006-2010.
