Abstract: Estimating urban vehicular emission factors and vehicular emissions amount with a model is an important research field of vehicular emissions control. At present, most applications in China are geared up for those well-developed “western” models such as MOBILE, which can be an alternative when lacking adequate emission data accumulation and relative research. Developed for different research goals, however, these models will inevitably face the incompatibility of local activities in China. Most researches focused on the calculation result of emission factors, while paying very little attention on the applicability of these models in China. On the base of domestic applications analysis, the authors compare these models' adaptability from aspects of model type, regional limitation, database integrality, parameter availability, and model flexibility. Finally, suggestion is given on how to choose model according to different situation.
