摘要:

基于北京市实测数据,分析了不同平均速度下的VSP 与瞬时速度分布规律,并建立了平均速度与进行排放测算所需的运行模式参数分布对应模型.此外,本文利用所开发的模型,以及MOVES 模型中的运行模式计算排放.结果显示,本文模型对HC,NOx和CO的预测误差分别为:6.9%,0.6%和0.3%,远远小于利用MOVES默认行驶周期计算而得的误差.

Abstract:

The research in this paper analyzes the relationship between VSP and the instantaneous speed based on the vehicle activity data collected in Beijing, and develops the distribution model of average speeds corresponding to the operating mode parameters needed for the estimation of vehicle emissions. Finally, a comparative analysis between the operating mode distributions from the proposed model and MOVES with that from the real-world data is completed. For HC, NOx and CO, the errors generated are 6.9%, 0.6% and 0.3% by proposed model, which are closer to the real-world data than MOVES.

Key words: urban traffic, operating mode, VSP, average speed, emission estimation
