摘要：
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. © 2020, Editorial Board of Journal of Systems Engineering Society of China.
