CR Associates provided technical support to this project led by the University of California, Berkeley Sate Transportation Research and Education Center (SafeTREC). The study aimed to measure mode shift changes at schools in response to Safe Routes to School program investments. Ten schools throughout the state of California with Safe Routes to School programs were monitored as a part of this study. CR Associates formed databases comprised of land use, transportation, and demographic variables for the schools under evaluation. The study found that perceptions of safety about walking to school and walking mode share improved after investments were made.
