简要总结
Installing specific traffic calming features designed to reduce vehicle speed and volume around schools may lead to a reduction in injury risk for child pedestrians and bicyclists, and may increase numbers of children walking and bicycling to school. Therefore, this study seeks to evaluate the effectiveness of specific built environment features at influencing traffic speed and volume, and active transportation, both immediately following installation and months later.
详细描述
Background Collisions with motor-vehicles are a leading cause of severe child bicyclist and pedestrian injuries in Canada. Injury rates and severity are associated with traffic speeds and volume but may be moderated through traffic calming.
Objective To assess the association of specific traffic calming measures on changes in traffic speed and volume, and active transportation prevalence, around Calgary, Alberta, Canada elementary schools.
Design This modified stepped-wedge randomized controlled trial was conducted at a sample of public elementary schools, from July 2020 to May 2021. Schools had either traffic calming curbs or in-street signs installed at an intersection within 100 m of the main entrance. The primary outcome was speed of vehicles driving towards or away from intervention. Secondary outcomes were traffic volume driving past the intervention and counts of children using active transportation at the intervention crosswalk.

结局指标
主要结局
Traffic Speed - Post-intervention
时间窗: At each location, a week of post-intervention data collection will occur a week after the intervention being installed.
Traffic speed of all vehicles who pass by the intervention will be recorded.
Traffic Speed - Pre-intervention
时间窗: At each location, a week of pre-intervention data collection will occur a week prior to the intervention being installed.
Traffic speed of all vehicles who pass by the intervention will be recorded.
Traffic Speed - Follow-up
时间窗: At a random selection of locations (drawn from those that received the intervention during the school year), a week of data collection will occur during the spring following the installation of the intervention.
Traffic speed of all vehicles who pass by the intervention will be recorded.
