Abstract

Air pollution, an unexpected event, poses a significant threat to public health and affects human mobility. Ride-hailing provides an effective way to understand how human mobility adapts to air pollution. This study examines a week-long ride-hailing demand dataset from Chengdu, China, to evaluate the resilience of ride-hailing services (or ride-hailing resilience) in the face of poor air quality. A gradient boosting decision tree model is developed to explore the non-linear and interaction effects of air pollution, the built environment, and socioeconomic characteristics on ride-hailing demand and resilience. The results show that the relative importance and impact of independent factors on ride-hailing demand and resilience vary. Specifically, the density of residence facilities and air pollution are the most important predictors of ride-hailing demand and resilience, respectively. The non-linear and interaction effects of air pollution and selected built-environment and socioeconomic characteristics on ride-hailing resilience are presented. We recommend that urban planners and policymakers address the vulnerability of regions to air pollution, optimize the allocation of ride-hailing resources, and develop strategies to improve regional resilience.

打车服务应对空气污染的复原力及其与建筑环境和社会经济特征的关系

空气污染这一突发事件对公众健康构成了重大威胁，并影响着人类的流动性。打车服务是了解人类出行如何适应空气污染的有效途径。本研究考察了中国成都为期一周的打车需求数据集，以评估打车服务在面对恶劣空气质量时的弹性（或打车弹性）。研究开发了梯度提升决策树模型，以探索空气污染、建筑环境和社会经济特征对打车需求和弹性的非线性和交互影响。结果表明，独立因素对打车需求和弹性的相对重要性和影响各不相同。具体而言，居住设施密度和空气污染分别是预测乘车需求和弹性的最重要因素。我们还介绍了空气污染、选定的建筑环境和社会经济特征对乘车弹性的非线性效应和交互效应。我们建议城市规划者和政策制定者解决地区易受空气污染影响的问题，优化打车资源配置，并制定提高地区弹性的战略。

期刊介绍： A major resurgence has occurred in transport geography in the wake of political and policy changes, huge transport infrastructure projects and responses to urban traffic congestion. The Journal of Transport Geography provides a central focus for developments in this rapidly expanding sub-discipline.
