In response to the increased traffic congestion and worsening air pollution, using the portable emission measurement system (PEMS), this paper analyzes the relationship between emissions and speed, acceleration (qualitatively and quantitatively), and then establishes emission models of vehicles. The data in this paper is according to on-board emission measurement data of Beijing Jiaotong University. Furthermore, comparing the classic emission model (CMEM) based on Vissim, the models of data fitting in this paper are proved to be effective and more convenient. The obtained results provide a new approach for improving the classic emission models, which is more suitable for China or any other country/district.
