Abstract

The nonlinearity correlations of design and land-use features with active travel (AT) are yet to be systematically identified by recent studies. This study aims to apply the extreme gradient boosting approach to examine the nonlinear relationships between design and land-use built environment (BE) features and AT. Based on a comprehensive travel survey in Wuhan’s main agglomeration with various land use and urban functions, we collected 2073 valid samples to obtain residents’ daily travel patterns and socio-demographic attributes. We found that all BE features have nonlinear relationships with AT. The collective relative importance of design features has greater predictive power for AT than land-use features. The most effective range of high contributions of street connectivity and street greenery was 21–34/km² and 0.22–0.34, respectively. Planners should improve the street-level features and build dense, diverse land use and high street connectivity urban environments to promote AT activity.

设计、土地使用特征与积极出行之间的非线性关系

设计和土地利用特征与主动出行（AT）的非线性相关性尚未被近期的研究系统识别。本研究旨在应用极端梯度提升方法来研究设计和土地利用建筑环境（BE）特征与主动出行之间的非线性关系。基于对武汉市主要城市群的各种土地利用和城市功能的全面出行调查，我们收集了 2073 个有效样本，以获得居民的日常出行模式和社会人口属性。我们发现，所有建筑设计特征都与交通流量存在非线性关系。与土地利用特征相比，设计特征的集体相对重要性对交通流量的预测能力更强。街道连通性和街道绿化的高贡献最有效范围分别为 21-34/km2 和 0.22-0.34。规划者应改善街道层面的特征，建设密集、多样化的土地利用和高街道连通性的城市环境，以促进人们的自闭症活动。

期刊介绍： Transportation Research Part D: Transport and Environment focuses on original research exploring the environmental impacts of transportation, policy responses to these impacts, and their implications for transportation system design, planning, and management. The journal comprehensively covers the interaction between transportation and the environment, ranging from local effects on specific geographical areas to global implications such as natural resource depletion and atmospheric pollution. We welcome research papers across all transportation modes, including maritime, air, and land transportation, assessing their environmental impacts broadly. Papers addressing both mobile aspects and transportation infrastructure are considered. The journal prioritizes empirical findings and policy responses of regulatory, planning, technical, or fiscal nature. Articles are policy-driven, accessible, and applicable to readers from diverse disciplines, emphasizing relevance and practicality. We encourage interdisciplinary submissions and welcome contributions from economically developing and advanced countries alike, reflecting our international orientation.
