摘要
为计算交叉口NOx排放量与排放因子的变化,并分析交叉口机动车尾气排放的规律,通过将机动车废气模拟系统(MOVES)排放模型与VISSIM交通仿真模型相结合的方法研究了NOx尾气排放特性,以及仿真分析交叉路口不同类型公交站台对机动车尾气排放情况的影响。结果表明:新型交叉路口比传统交叉路口NOx降低0.27 g。公交车在交叉口上游港湾式、下游港湾式与下游拓宽港湾式NOx实测数据是模型数据的1.14、1.28和1.24倍,在模拟实验中,NOx污染物在下游相同区域排放量降低15.07%,排放因子降低14.67%。可见通过交通模型对研究实际交叉路口公交站台NOx排放特性有实际意义。
The study aimed to calculate the change of NOx emission and emission factors at the intersection,and analyze the law of vehicle exhaust emission at the intersection,the NOx emission characteristics were studied by combining the motor vehicle emission simulator(MOVES)emission model with VISSIM traffic simulation model,and the influence of different types of bus stops at intersections on vehicle emissions was simulated and analyzed.The results show that the NOx of the new intersection is 0.27 g,lower than that of the traditional intersection.The measured data of NOx of upstream bay,downstream bay and downstream widened bay at the intersection of buses are 1.14,1.28 and 1.24 times higher than that of the model data.In the simulation experiment,the emission of NOx pollutants in the same area downstream was reduced by 15.07%and the emission factor was reduced by 14.67%.Therefore,it is of practical significance to study the NOx emission characteristics of bus stations at actual intersections through the traffic model.
