为了达到低排放低延误的交通信号多目标优化控制的目的，首先对车辆行驶轨 迹进行描述，并基于机动车比功率( VSP) 进行机动车排放的计算; 然后利用回归分析的方 法，对排放和延误的关系进行量化; 之后建立一个以减少排放和降低延误为目标的交通信 号控制模型，以此来优化信号控制交叉口的周期时长和绿灯时长，从而达到低排放、低延 误的交通信号多目标智能化控制． 选取了长春市典型交叉口进行调查，并运用仿真软件 VISSIM 对该模型进行仿真验证． 优化前后的对比分析表明，延误减少了 10． 54% ，排放降 低了 13． 41% ，从而证明了该控制技术的有效性

In order to achieve low emissions and short delays through the multi-objective optimization control of traffic signals，first，the trajectory of the vehicle is described，and the vehicle emissions are calculated based on the vehicular specific power ( VSP) ． Then，the relationship between emissions and delays is quantified by means of the regression analysis，and a traffic signal control model for reducing emissions and shortening delays is constructed to optimize the cycle time and the green time of the signal control intersection． Thus，low emissions and short delays are realized through the multi-objective intelligent control of traffic signals． Finally，the constructed model is verified by a VISSIM simulation and on the basis of a survey about a typical intersection in the city of Changchun． Comparative analysis of the results before and after the optimization shows that the delays are shortened by about 10. 54% and the emissions are reduced by 13. 41%，which proves that the proposed control technology is effective．
