本研究报道了为遏制SARS-CoV-2病毒（导致COVID-19疾病）传播而实施的限制措施对葡萄牙里斯本城市交通和空气质量的影响。我们采用基于数据的分析方法对里斯本智慧城市数据进行了研究，这些数据来自多个来源，例如交通和污染数据。在首个葡萄牙紧急时期（2020年3月18日至2020年5月3日），人为活动的急剧减少，尤其是道路交通，导致与2013-2019年期间全市六个空气质量监测站测量的同基准线相比，常规空气污染物浓度普遍降低。受影响最严重的空气污染物是NO2，在交通站点减少了54.35%，在背景站点减少了28.62%。Google本地商业移动性指标被确定为里斯本人为活动的主要指标，与NO2浓度呈中等正相关（r=+0.54）。训练了一个回归机器学习（ML）管道，利用2020年3月至2021年3月期间可用的人为活动、气象和空气污染物输入预测NO2浓度，在测试集上达到R2=0.925。
