摘要
为解决城市复杂路网系统特定时期各路段机动车大气污染物排放量的精确计算问题,提出一种新的机动车污染物排放量计算方法.首先构建路网拓扑模型;其次利用复杂管网液体流动模拟路网机动车流动行为,根据流动规律构建机动车流计算模型,并给出其求解算法-邻域自适应差分进化(NADE,neighborhood adaptive differential evolution)算法;然后结合排放因子计算机动车污染物排放量,并揭示其排放特征;最后以大西安主城区路网为例对该方法进行实例验证.结果表明:该方法计算结果贴近各路段污染物实际排放情况,通用性强,适用于复杂路网机动车流量和污染物排放量的动态测算.
In order to solve the problem of precise calculation for vehicle air pollutant emission in specific period and each section of complex urban traffic network system,a new calculation method for vehicle pollutant is proposed.Firstly,the road network topology model is constructed;secondly,the fluid flow in complex pipeline network is used to simulate the motor vehicle flow behavior in road network,and the computational model of motor vehicle flow is constructed according to the law of motor vehicle flow in road network,and its solution algorithm-neighborhood adaptive differential evolution(NADE)algorithm is given;then,combined with the emission factor,emission of pollutant from motor vehicle is computed,and the emission characteristic is revealed;finally,the method is tested by taking the road network of the main urban area of Greater Xi'an as an example.The results show that the calculation result of this method is close to the actual emission of pollutant in every road section,and it has strong versatility,and it is suitable for the dynamic calculation of vehicle flow and pollutant emission in complex road network.
