Abstract

The scientific layout of child-friendly facilities in the community is of great significance to children's daily activities and healthy growth, which is also a vital concern of the United Nations. However, there is little evidence to prove the intrinsic mechanism of children's daily travel behavior and daily travel destinations. Therefore, this study takes 118 communities in Shuangliu District, Chengdu, as an example and uses a eXtreme Gradient Boosting (XGBoost) model to explore the non-linear effects and threshold effects of children's daily travel distance on their travel mode choices by considering different destinations of children's daily travel in the communities. We found that children's daily travel distances and destinations are vital for their travel mode choice, especially the most significant effect of travel distance. For different children's daily travel destinations, travel distance has a more substantial threshold effect on children's non-walking travel mode choice. Therefore, to scientifically and rationally distribute child-friendly facilities in the community, which may help children's healthy development, a child-friendly city should be planned, constructed, or renewed through the internal logical relationship between children's daily travel destinations, travel distances, and travel mode choices should be considered comprehensively.

考虑到不同目的地，儿童每日出行距离对其出行方式选择的非线性影响

在社区中科学布局儿童友好型设施，对儿童的日常活动和健康成长具有重要意义，这也是联合国极为关注的问题。然而，儿童日常出行行为和日常出行目的地的内在机理却鲜有证据证明。因此，本研究以成都市双流区的 118 个社区为例，采用极端梯度提升（XGBoost）模型，通过考虑社区内儿童日常出行的不同目的地，探讨儿童日常出行距离对其出行方式选择的非线性效应和阈值效应。我们发现，儿童的日常出行距离和目的地对他们的出行方式选择至关重要，尤其是出行距离的影响最为显著。对于不同儿童的日常出行目的地，出行距离对儿童非步行出行方式选择的门槛效应更为显著。因此，为了科学合理地在社区内分布有助于儿童健康成长的儿童友好型设施，应通过综合考虑儿童日常出行目的地、出行距离和出行方式选择之间的内在逻辑关系，规划、建设或更新儿童友好型城市。
