To achieve accurate emission simulation for car-following vehicles, this paper proposes a calibration and optimization method based on minimizing the error between the Vehicle Specific Power (VSP) distribution of car-following models and the measured lead vehicle. By constructing an objective function to minimize VSP distribution error, the parameters of the car-following models are calibrated to enhance the model's realism. Using measured emission data of the lead vehicle, the emission characteristics of various car-following models are fitted and compared. The results show that Gipps, IDM, OVM, GFM, and FVDM models all demonstrate favourable VSP distributions and effective fitting of following vehicle emission; The Gipps model demonstrated optimal performance in VSP distribution fitting accuracy (mean Root Mean Square Error (RMSE) of 0.003 7) and emission factor fitting for CO2, NOx, CO, and Partical Number (PN) emission factors (mean relative error to the reference vehicle of 0.93%). In multi-vehicle platooning emission simulations, the Gipps model exhibits the smallest emission fluctuations. The mean relative errors for CO2, NOx, CO, and PN emission factors are 0.48%, 0.52%, 0.87%, and 1.89% respectively. The model demonstrates optimal consistency in fitting emissions across all platooning vehicles.

为了获得良好的跟驰车辆排放仿真效果,提出一种基于最小化跟驰车辆比功率(VSP)分布与实测头车误差的标定优化方法。利用VSP分布误差最小化目标函数标定跟驰模型参数,优化跟驰模型真实性;结合实测头车的排放数据,拟合多种跟驰模型的排放情况。试验结果表明:Gipps、IDM、OVM、GFM、FVDM模型均表现出良好的VSP分布和跟驰车辆排放拟合效果;Gipps模型在VSP分布拟合精度(均方根误差均值为0.003 7)和CO2、NOx、CO、颗粒物数量(PN)排放因子拟合效果(与头车的相对误差均值为0.93%)上表现最优;多车辆跟驰车队排放仿真中,Gipps模型的排放波动最小,CO2、NOx、CO、PN排放因子相对误差均值分别为0.48%、0.52%、0.87%、1.89%,各跟驰车辆拟合排放的一致性最优。

为了获得良好的跟驰车辆排放仿真效果,提出一种基于最小化跟驰车辆比功率(VSP)分布与实测头车误差的标定优化方法。利用VSP分布误差最小化目标函数标定跟驰模型参数,优化跟驰模型真实性;结合实测头车的排放数据,拟合多种跟驰模型的排放情况。试验结果表明:Gipps、IDM、OVM、GFM、FVDM模型均表现出良好的VSP分布和跟驰车辆排放拟合效果;Gipps模型在VSP分布拟合精度(均方根误差均值为0.003 7)和CO2、NOx、CO、颗粒物数量(PN)排放因子拟合效果(与头车的相对误差均值为0.93%)上表现最优;多车辆跟驰车队排放仿真中,Gipps模型的排放波动最小,CO2、NOx、CO、PN排放因子相对误差均值分别为0.48%、0.52%、0.87%、1.89%,各跟驰车辆拟合排放的一致性最优。

To achieve accurate emission simulation for car-following vehicles, this paper proposes a calibration and optimization method based on minimizing the error between the Vehicle Specific Power (VSP) distribution of car-following models and the measured lead vehicle. By constructing an objective function to minimize VSP distribution error, the parameters of the car-following models are calibrated to enhance the model's realism. Using measured emission data of the lead vehicle, the emission characteristics of various car-following models are fitted and compared. The results show that Gipps, IDM, OVM, GFM, and FVDM models all demonstrate favourable VSP distributions and effective fitting of following vehicle emission; The Gipps model demonstrated optimal performance in VSP distribution fitting accuracy (mean Root Mean Square Error (RMSE) of 0.003 7) and emission factor fitting for CO2, NOx, CO, and Partical Number (PN) emission factors (mean relative error to the reference vehicle of 0.93%). In multi-vehicle platooning emission simulations, the Gipps model exhibits the smallest emission fluctuations. The mean relative errors for CO2, NOx, CO, and PN emission factors are 0.48%, 0.52%, 0.87%, and 1.89% respectively. The model demonstrates optimal consistency in fitting emissions across all platooning vehicles.
