Abstract
To monitor the carbon footprint of electric bus operations, this paper proposes a method to estimate the converted carbon emissions of electric buses based on the actual driving conditions. Taking the bus route 609 operating in the urban area of Xi'an City and the bus route 362 in the new built urban area as examples, based on real world driving data, a developmentscheme of localized driving cycles for urban electric bus operation lines is proposed. The T-distributed stochastic neighbor embedding (T-SNE) method is used for data dimensionality reduction. The Birch clustering method is used for classification, and then the driving cycles of the two study bus routes were constructed based on the principle of highest similarity and the ratio of each speed interval. The carbon emission is obtained through the conversion formula based on the power consumption calculated in cruise simulation environment. The results indicate that the electric bus routes 609 and 362 show obvious different energy consumption per 100 kilometers, which are respectively 121.71 kilowatt hourand 144.46 kilowatt hour. The result proves the necessity of constructing driving cycles for different bus routes. The carbon footprints of the routes 609 and 362 in November 2019 were also calculated based on the proposed method, which are respectively 114.099 ton and 117.863 ton. The proposed carbon footprint calculation method for electric bus is helpful for urban transportation carbon emission monitoring and management.
