Since Safe Routes to Schools (SR2S) methods first gained prominence in the 1990s, researchers and practitioners have been working to determine best practices that can yield improvements in two areas: improved health and increased ATS participation. Many of these projects and programs have focused on the provision of physical infrastructure that can improve perceived and actual safety for children on walking and bicycling journeys to school. This literature review provides a summary of key research available on SR2S public health and ATS outcomes and additionally offers several insights into the state of the practice. Highlights among these are the findings that sidewalk and traffic signal upgrades measurably reduced the incidents of child pedestrian collisions and child pedestrian injury rates.
In terms of ATS outcomes, several sources have found encouraging results. Both in terms of perceived and actual safety impacts, sidewalk gap closure and traffic signal upgrade SR2S projects were found to yield increases in the likelihood of children walking to school, and even greater increases when infrastructure interventions like these were combined with education programs.
