Abstract

Public transport improves mobility and well-being for the rapidly aging population. However, few planning interventions have addressed the urban–rural disparity in bus usage among older adults. Using data from Zhongshan, China, this study adopts the eXtreme Gradient Boosting (XGBoost) model to examine urban–rural differences in the nonlinear relationship between built environment and daily bus usage among elderly adults. The results indicate nonlinearities across all built environment variables and stronger effects of the built environment in rural areas. Distance to transit contributes the most in urban neighborhoods but least in rural ones. Furthermore, dwelling unit density and green space accessibility play the biggest roles in the rural context. Additionally, the most effective ranges of intersection density, land use mixture, and CBD accessibility are greater in rural areas. The findings facilitate fine-grained and diversified planning interventions to facilitate bus usage among older adults in both urban and rural areas.

建筑环境与老年人公交使用率之间的关系:非线性的城乡差异
公共交通改善了快速老龄化人口的流动性和福祉。然而,很少有规划干预措施能解决老年人使用公交车的城乡差异问题。本研究利用中国中山的数据,采用极端梯度提升(XGBoost)模型,研究了建筑环境与老年人每日公交使用率之间非线性关系的城乡差异。结果表明,所有建筑环境变量之间都存在非线性关系,而建筑环境对农村地区的影响更大。在城市地区,公交距离的影响最大,而在农村地区,公交距离的影响最小。此外,居住单元密度和绿地可达性在农村地区的作用最大。此外,在农村地区,交叉口密度、土地使用混合和中央商务区可达性的最有效范围更大。这些发现有助于采取精细化和多样化的规划干预措施,以促进城市和农村地区老年人使用公交车。
