道路连通性的微小变化对学生步行潜力的影响
The impact of small changes in thoroughfare connectivity on the potential for student walking
摘要：
学生积极通勤上学是学生成绩和学生健康的重要组成部分，但这种形式的体育活动在美国已显着下降。据报道，学校和学生宿舍之间的距离通常是学生步行的障碍，因此，增加住宅区和学校之间和内部的街道和小径连接可以促进学生步行。本研究的目的是评估在学校步行区内增加通道连接对学生步行的潜在好处。这项研究进行了一项成本效益分析，在美国的学校系统，为6万名学生提供服务的小学和中学周围增加通道连接。好处，其中包括增加时间的身体活动，从学生步行和潜在的成本节省学校系统，如果他们有更少的学生巴士上学，比较新的连接的财务成本。先进的网络优化技术应用于几个郊区和农村学校从一个代表性的学校系统，以找到最佳的新的通道连接，最大限度地提高学生步行到学校，并尽量减少新的通道的长度。从这个案例研究的结果表明，短和便宜的新的通道可以增加学生活跃的通勤者的潜在数量，并为这些潜在的学生步行者提供了显着增加的身体活动。这项工作可以促进学生步行和学生健康在学校周围的住宅规划决策的整合。
英文摘要：
Student active commuting to school is an important component to student achievement and student health, yet this form of physical activity has significantly declined in the U.S. Distance between the school and student residence is often reported as a barrier for student walking, thereby increasing street and trail connectivity between and within residential developments and schools could foster student walking. The purpose of this study is to evaluate the potential benefits of increased thoroughfare connectivity on student walking within school walking zones. This study conducts a cost-benefit analysis of increased thoroughfare connectivity around elementary and middle schools in a U.S. school system that serves sixty thousand students. Benefits, which include the increased time of physical activity from student walking and the potential cost-savings to a school system if they had fewer students to bus to school, are compared to the financial costs of the new connections. Advanced network optimization techniques were applied to several suburban and rural schools from a representative the school system to locate the optimal new thoroughfare connections that maximize student walking to a school and minimize the length of the new thoroughfare. Results from this case study showed that short and inexpensive new thoroughfares could increase the potential number of student active commuters and provide a significant increase of physical activity for those potential student walkers. This work can foster the integration of student walking and student health in residential planning decisions around schools.
