Abstract: Aiming at the problem of establishing the objective function of traffic emission and fuel consumption of roundabout in the study of traffic organization optimization of roundabout considering environmental benefits, a traffic emission and fuel consumption calculation model at roundabout based on VT-micro model was proposed by combining traffic flow parameter model with traffic emission and fuel consumption model, referring to the related modeling ideas. The research shows that the proposed model can accurately estimate the traffic emissions and fuel consumption of roundabout, and can be used for the quantitative analysis of the emissions and fuel consumption of roundabout, which is of great significance for the optimization of roundabout based on environmental benefits.

Key words: traffic and transportation engineering, roundabout, VT-micro model, traffic emissions, fuel consumption

摘要: 针对考虑环境效益的环形交叉口交通组织优化研究中,环形交叉口交通排放及燃油消耗目标函数的建立问题,参考相关建模思想,采用交通流参数模型与交通排放、燃油消耗模型相结合的方法,提出了一种基于VT-micro模型的环形交叉口处交通排放及燃油消耗量计算模型。研究表明:提出的模型可以较为准确地对环形交叉口交通排放及燃油消耗量进行估算,可用于环形交叉口排放及燃油消耗的定量分析,对基于环境效益的环形交叉口优化研究具有重要意义。
