Due to the great difference between an internal combustion engine vehicle (ICEV) and a new energy vehicle (mainly including a plug-in electric vehicle (PEV) and a hybrid electric vehicle (HEV)) in emission, a traditional environmental impact assessment method is challenging. According to the method, an absorption Markov chain model is used for modeling the transfer process between main vehicle types in the future. In addition, it is assumed that the behavior of a new energy automobile traveler is the same as that of a traditional ICEV traveler. Therefore, the vehicle composition of each road section is consistent with the market penetration level. Therefore, environmental impact assessment can be performed based on the market penetration levels of different vehicle types and the road traffic flow. For a given road network, traffic system equalization is utilized to calculate road segment traffic flow. The method is a four-stage model with feedback, and can be effectively solved througha weight decreasing continuous average method (MSA). The effectiveness of the proposed method is verified by using the simulation research of the Nguyen-Dupuis network.
