Augmented emission maps: model for deterioration factor for fallback maps (Diesel / Petrol Euro 1-6)

In order to enable the sharing of data the emission data for vehicles is standardized. The data exchange format contains all data that is applicable for a specific engine taxonomy code. The standardized emission map has a “.map.txt” extension and is also human readable. The files starts with metadata which contains information about: the engine taxonomy code, total driven kilometers over which the data was gathered, total time in hours over which the data was gathered, the number of vehicles which were tested to create the emission map, the DOI (Digital Object Identifier) reference, Which emission maps are available in the file. The DOI 10.5281/zenodo refers to a meta-data document that provides the full description of the standardized emission map.为实现车辆排放数据的共享，本数据集对车辆排放数据进行了标准化处理。该数据交换格式涵盖适用于特定发动机分类代码的全部相关数据。标准化排放图谱（standardized emission map）的文件扩展名为".map.txt"，且具备人类可读特性。文件以元数据开篇，其中包含以下信息：发动机分类代码、采集数据的总行驶里程、数据采集总时长（以小时为单位）、用于生成该排放图谱的测试车辆总数、数字对象标识符（DOI，Digital Object Identifier）引用，以及文件中包含的可用排放图谱列表。DOI 10.5281/zenodo 指向一份元数据文档，该文档完整说明了该标准化排放图谱的全部细节。
