摘要
为分析城市道路实际交通条件下汽车尾气的排放规律,对元胞自动机的MCD模型和STCA模型进行改进,构建一种基于速度-加速度查询表耦合交通流元胞自动机的汽车尾气排放量统计模型。在不同交通流服务水平下运行该耦合模型,以获取速度、加速度及工况。对单车的工况分布、3种典型尾气排放历程及1 h与1 km排放总量进行统计分析,结果表明,该模型耦合机理清晰,可用于实际交通服务水平下单车及车流尾气排放规律的分析。
In order to analyze the exhaust emission regularity under the actual traffic conditions of urban roads,the MCD and STCA models of cellular automaton are improved,on this basis,a model based on the speed-acceleration query table coupled with traffic flow cellular automaton is built for vehicle emission statistics.The coupling model is implemented under different traffic flow service levels,and the speed,acceleration and working conditions are obtained.The distribution of the vehicle’s working conditions,three typical exhaust emission processes,and the total emissions of 1 h and 1 km are statistically analyzed.The results show that the coupling mechanism of the model is clear,and it can be applied to analyze the discharge regularity of single vehicle and vehicle flow under the actual traffic service levels.
