摘要:

目前,VISSIM仿真工具与排放模型相结合的方法已被广泛应用于交通排放测算中,但该方法的测算精度尚未得到充分论证.在此背景下,本文通过收集大量的车辆实际行驶数据和VISSIM输出的仿真数据,对比分析由两类数据得到的排放关键参数——VSP分布,发现二者之间存在明显的差异性;随后基于VSP分布,本文将由VISSIM输出数据得到的排放因子与真实值对比,指出基于VISSIM仿真的排放测算具有显著误差.最后,在分析了VISSIM中8个参数调整前后VSP分布的变化后,发现上述参数对VSP分布的敏感性较低,表明传统的标定方法难以使VISSIM满足排放测算的需要.

Abstract:

Nowadays the integration of VISSIM and emission models has been widely applied in estimating emissions at home and abroad. However, the estimation accuracy of emissions by such an approach has not been effectively evaluated. In this context, by collecting massive driving and simulated vehicle activity data, this paper conducted a comparative analysis of the difference between them based on the explanatory parameter of vehicle emissionsvehicle specific power (VSP) distribution. This paper found that the simulated VSP distribution led to high errors in estimating emission factors. At last, with an analysis of adjustments on 8 parameters of VISSIM, it was found that these parameters are not sensitive on VSP distributions, and the current approach of model calibration may not be able to improve VISSIM to meet the needs of emission estimations.
