摘要

本研究采用现场观察、社会调查和环境建模的方法，调查了波兰华沙三所小学周围上下学期间家长行为对交通相关空气污染的影响。空转（20%的车辆在接车时被观察到，37%的车辆在接车时被观察到）、停车和停车时的巡航每分钟产生的排放量低于典型驾驶，但在所有学校周围造成大量超额排放（接车和下车时间的氮氧化物平均排放量相当于正常驾驶1.2公里）。这使当地二氧化氮浓度平均增加13%。过量排放的主要来源是：造成拥堵、空转和巡航。指定的学校交通约占总交通的10%，但它对正常交通的中断影响了所有车辆的排放。虽然单独来看影响不大，但家长行为对学校周围空气质量的累积影响意味着提高意识活动和优化接送区设计等方面的改进。

How idling and maneuvering affect air quality: Case study of school commutes

Present study investigates the influence of parental behaviors during school pick-up and drop-off on traffic-related air pollution surrounding three primary schools in Warsaw, Poland, using in-situ observations, social surveys and environmental modelling. Idling (20 % of cars observed during pick-up and 37 % during drop-off), parking, and cruising for parking generate lower emissions per minute than typical driving, however cause large excess emissions around all schools (NOx average emissions during pick-up and drop-off hours were equivalent to 1.2 km of normal driving). This increases local NO₂ concentrations by 13 % on average. The main sources of excess emissions were: causing congestion, idling, and cruising. Designated school traffic constituted about 10 % of overall traffic, but its disruptions to the regular flow impacted emissions of all vehicles. While individually minor, the cumulative impact of parental behaviors on the air quality around schools implies improvements such as awareness campaigns and optimized design of pick-up/drop-off zones.

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.
