Intervention <p>School Street initiatives are traffic-free zones around the entrances of primary schools designed to make it safer for children to come and go from school. Beyond increasing safety, these initiatives offer opportunities for children to increase their engagement in active school travel and to become more independently mobile.</p> Research question <p>How does the implementation of a School Street intervention influence children’s active travel and independent mobility on their way to school?</p> Methods <p>A School Street intervention was implemented every Friday at a primary school in Montreal from September 2022 to June 2023. Bi-monthly direct observations were conducted to collect data on children’s modes of travel and whether they travelled independently or with an adult before the start of classes.</p> Results <p>Independent, active travel was more frequently observed on School Street days compared to non-School Street days. Additionally, a progressive increase in active transportation and independent mobility was observed throughout the school year, regardless of School Street designation.</p> Conclusion <p>This study underscores the potential impact of School Street interventions on enhancing children’s active school travel and independent mobility. Establishing safe zones near schools can positively influence children’s commuting behaviours, fostering healthier and more autonomous travel habits.</p>
