This paper presents SHERPA-City, a web application to assess the potential of traffic measures to abate NO₂ air pollution in cities. The application is developed by the Joint Research Centre. It is freely available (https://integrated-assessment.jrc.ec.europa.eu) and allows the user to perform a fast screening of possible NO₂ abatement measures addressing traffic in European cities. SHERPA-City results depend on the quality of the default input data. It is therefore important to stress that the SHERPA-City default traffic flows, emission factors, fleet composition, road network topology, NO₂ pollution from other sources and meteorological data are based on EU-wide datasets that may not always represent perfectly a particular local situation. This is why the SHERPA-City allows the default data to be substituted by local data, to better reflect local features. This tool must be considered as a first step in exploring options to abate NO₂ air pollution through transport measures. The final decisions should be based, wherever possible, on full-scale modelling studies incorporating local knowledge.

本文介绍了SHERPA-City，这是一个网络应用程序，用于评估采取交通措施减少城市中NO ₂空气污染的潜力。该应用程序由联合研究中心开发。它是免费提供的（https://integrated-assessment.jrc.ec.europa.eu），并允许用户快速筛选可能的NO ₂减排措施，以解决欧洲城市的交通问题。SHERPA-City结果取决于默认输入数据的质量。因此，需要强调的是，SHERPA-City默认交通流量，排放因子，车队组成，道路网络拓扑，NO ₂其他来源的污染和气象数据均基于欧盟范围内的数据集，这些数据集可能并不总是完全代表特定的当地情况。这就是SHERPA-City允许将默认数据替换为本地数据以更好地反映本地功能的原因。该工具必须被视为探索通过运输措施减少NO ₂空气污染的备选方案的第一步。最终决策应尽可能基于结合本地知识的全面建模研究。
