摘　　要：从减少交叉口机动车排放量的角度,分析了信号控制对机动车排放影响因素的作用机理,阐述了信号配时–行驶工况–机动车排放三者之间的关系;根据机动车行驶工况变化对排放的影响,建立了车辆完全停车、不完全停车以及不停车3种状态下的机动车排放计算模型;以交叉口车均排放增加量最小为优化目标,确定了信号配时方案的优化方法.以长春市某典型信号交叉口实测数据进行模型验证,结果表明交叉口机动车排放量降低了6.43%.In this paper,first,from the viewpoint of reducing the vehicle emission at road intersection,the mechanism how the signal control impacts vehicle emission is analyzed,and the relationship among signal timing,running state and vehicle emission is investigated.Next,according to the effect of running state on the emission,some mo-dels are established to describe the emission respectively in complete-stop,uncompleted-stop and non-stop states.Then,an optimization method of signal timing scheme is proposed by taking the least incremental emission as the objective.Finally,a verification experiment is performed with the real data of a typical intersection in Changchun,China.The results show that the proposed optimization model helps to reduce the vehicle emission by 6.43%.
