摘　　要：健康安全的通学道能够促进儿童步行通学,助其身心健康与成长发展。以儿童步行通学的特征为切入点构建指标,评测现有通学道环境的健康安全性,旨在为未来通学道的建设提供参考与借鉴。选取北京市垂杨柳中心小学为研究案例,在机器学习技术的辅助下评测小学周边通学道并绘制不同类型通学道画像,提出具有针对性的优化策略。研究发现,街道功能的差异在不同维度上影响步行通学的健康安全性,因此针对不同的通学道应当提出适宜的设计策略。Healthy and safety streets can promote children’s walking, it’s vital for children to be sound in body and mind. In order to provide reference with the future construction of the walking way to school, we construct the evaluation indexes from the perspective of children’s behavior characteristics to evaluate the healthy and safety of the existing urban streets. Taking Beijing Chuiyangliu Central Primary School as a case study, we evaluated the streets environment around the primary school with the help of machine learning technology, and then we drew portraits for every kind of streets and put forward targeted optimization strategies. It is found that the differences of street functions affect the health and safety of general pedestrian study in different dimensions. Therefore, appropriate design strategies should be put forward for different types of streets.
