GreenAnt Travel data, example dataset

This dataset contains data collected by a smartphone application GreenAnt about users movement in restricted geographical areas. The data collected was used to calculate personal and area summary of air quality exposure to NO2, PM2.5 and PM10. In addition calculation of emissions from diesel and petrol cars (nox, pm, voc, co2). Due to over 4.5 mill collected records, this dataset is only an extraction and works as an example. The example dataset has been checked and verified according to privacy issues本数据集收录了由智能手机应用GreenAnt采集的、关于用户在受限地理区域内活动的相关数据。所采集的数据被用于计算个人及区域层面的NO₂、PM2.5、PM10空气质量暴露情况的汇总统计，此外还可用于计算柴油车与汽油车的污染物排放量，相关污染物包括nox（氮氧化物）、pm（颗粒物）、voc（挥发性有机物）以及co2（二氧化碳）。由于原始采集记录超过450万条，本数据集仅为其中的提取子集，仅作示例使用。本示例数据集已针对隐私合规问题完成核查与验证。
