为合理、准确量化空驶状态下出租汽车空气污染排放总量及比例，基于深圳市出租汽车GPS数据，构建考虑空驶距离的出租汽车空气污染排放模型。经过数据筛选，以深圳市3198辆出租汽车为分析对象，识别出租汽车空驶和载客状态，进而计算载客距离和空驶距离。结合已有的三类出租汽车空气污染排放模型，考虑出租汽车空驶距离分别构建改进模型。参考已有研究成果设定空气污染排放因子，计算得到三类模型对应的空驶过程中出租汽车空气污染排放量占各自污染排放总量的比例分别为25.4%，34.2%和18.9%。最后，从排放因子、行驶距离、燃油经济性等方面探讨出租汽车空气污染减排策略。
為閤理、準確量化空駛狀態下齣租汽車空氣汙染排放總量及比例，基于深圳市齣租汽車GPS數據，構建攷慮空駛距離的齣租汽車空氣汙染排放模型。經過數據篩選，以深圳市3198輛齣租汽車為分析對象，識彆齣租汽車空駛和載客狀態，進而計算載客距離和空駛距離。結閤已有的三類齣租汽車空氣汙染排放模型，攷慮齣租汽車空駛距離分彆構建改進模型。參攷已有研究成果設定空氣汙染排放因子，計算得到三類模型對應的空駛過程中齣租汽車空氣汙染排放量佔各自汙染排放總量的比例分彆為25.4%，34.2%和18.9%。最後，從排放因子、行駛距離、燃油經濟性等方麵探討齣租汽車空氣汙染減排策略。

To effectively measure the total amount and proportion of taxicab emissions considering empty driving, this paper develops an empty driving distance-based taxicab emission model based on taxi GPS da-ta in Shenzhen. Targeting at 3,198 taxicabs in Shenzhen through data filtering, this paper recognizes taxies driving with or without passengers and calculate their driving distances. Based on the existing three types of taxicab emission models, the paper makes improvement separately with the empty driving distance tak-en into consideration. By selecting emission factors based on existing research, the paper estimates the pro-portions of taxicab emissions under empty driving to be 25.4%, 34.2%and 18.9%in total pollution emis-sions with the three models, respectively. Finally, the paper discusses strategies for taxicab emissions reduc-tion in different aspects including emissions factor, driving distance, fuel economy, and etc.
