构建了基于VISSIM微观交通仿真与CMEM排放模型的城市交通污染物排放计算平台，计算了郑州市某干道交叉口机动车污染物排放情况，分析了信号控制方式对交叉口机动车污染物排放的影响，结果表明，采用感应信号控制可以减少交叉口区域内机动车污染物的排放。%The paper establishes city traffic pollutant emission computation platform on the basis of VISSIM micro-traffic simulation and CMEM emission model,calculates the vehicle pollutants emission conditions of the intersection of major traffic road in Zhengzhou city,and analyzes the impact of signal control methods upon intersection vehicle pollutant emission. Results show that:applying sensitive signal control can reduce vehi-cle pollutants emission at intersection area.
