摘要

大气条件对中学生出行有着不可忽视的影响。本文旨在基于广义加法混合模型（GAMM），比较和探讨大气条件对北京市中学生出行方式选择的影响。研究发现，包括温度、湿度和空气污染物在内的许多大气条件对中学生的出行方式选择有显著的非线性影响，且不同变量的影响效果不同。例如，最低气温的升高会促使中学生选择积极的出行方式和汽车。湿度超过 50%与步行的学生比例呈负相关。PM2.5 浓度的增加有利于自行车的使用率，但对公共交通的使用率有负面影响。此外，O3 浓度对步行和汽车的使用呈 V 型影响，而对自行车和公共交通的使用则相反。这些发现加深了人们对大气条件对中学生出行行为影响的理解，并为政策制定者提供了参考。

The nonlinear effect of atmospheric conditions on middle-school students’ travel mode choices

Atmospheric conditions have non-negligible impacts on middle-school student travel. This paper aims to compare and explore the effect of atmospheric conditions on middle-school students’ travel mode choices in Beijing based on generalized additive mixed models (GAMM). Many atmospheric conditions, including temperature, humidity, and air pollutants, were found to have significant nonlinear effects on middle-school students’ travel mode choices, which vary by variables. For example, the increase in the lowest temperature motivates middle-school students to choose active travel modes and cars. Humidity exceeding 50% is negatively correlated with the percentage of students walking. Increased PM_2.5 concentration benefits the percentage of bike use but negatively affects public transport use. Moreover, O₃ concentration has a V-shaped effect on walking and car use, which is the opposite of bike and public transport. These findings advance the understanding of effects of atmospheric conditions on middle-school students’ travel behavior and provide references for policymakers.

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.
