论文摘要
城市地区的空中质量及其与公共卫生的关系是政府最关键的问题之一。因此，他们实施了旨在减少最关键大气污染物的集中度的行动，以及其他污染物的实施。马德里中央（Madrid Central）是马德里市议会（Madrid City Council）的一项重要倡议，该倡议是为了减少市中心的汽车交通和相关的空气污染。它是通过扩大限制电动机流量的先前和较小区域来创建的。该倡议始于2018年底，但第一个全面的时期对应于2019年第2季度（2019年第二季度）。低排放区的激活除了环保区外，还具有社会和经济影响。因此，必须评估它们的影响，以确保在降低大气污染物水平的降低中实现承诺。在这项工作中，提出了两个指标，以评估马德里中部对降低二氧化氮浓度的影响。从2010年到2019年的NO2的平均每日浓度对应于与卡门广场监测站相对应的，以评估马德里中心的影响。分析了马德里中央周围的另外两个监测站，以确定由于交通限制区域周围的电动机流量增加而导致有害影响的增加。结果，提出了两种方法论，依赖于评估LEZ的影响和演变的方法，以及关于马德里中心第一年的影响的陈述。
Air-quality in urban areas and its relation with public health is one of the most critical concerns for governments. For this reason, they implement actions aimed at reducing the concentration of the most critical atmospheric pollutants, among others the implementation of Low-Emission Zones. Madrid Central is a major initiative of Madrid city council for reducing motor traffic and the associated air pollution at the city center. It is created by enlarging a previous and smaller area of restricted motor traffic. This initiative starts at the end of 2018, but the first fully-operational period corresponds to 2019Q2 (second quarter of 2019). The activation of Low-Emission Zones has social and economic impacts, besides environmental ones. For this reason, their impact must be assessed to ensure the achievement of the commitments in the reduction of atmospheric pollutants levels. In this work, two metrics for evaluating the impact of Madrid Central in the reduction of nitrogen dioxide concentration are proposed. Mean daily concentrations of NO2 from 2010 to 2019 corresponding to the Plaza del Carmen monitoring station are employed for the evaluation of the impact of Madrid Central. Two other monitoring stations around Madrid Central are analysed for ascertaining the rise of detrimental effects due to an increment of the motor traffic around the traffic restricted area. In consequence, two methodologies pollutant-independent for evaluating the impact and the evolution of LEZs, as well as a statement about the impact of the first year of Madrid Central are presented.
