| 摘 要： | 运用了考虑排放和延误综合指标的城市信号交叉口信号配时方案,针对车辆在交叉口处不同运行特征下排放量的不同,提出了将车辆通过交叉口的运行特征与排放因子结合的方法,得出了车辆在交叉口的排放模型.在此基础上建立了考虑车辆排放和延误综合指标的城市交叉口信号优化控制模型,并运用改进的遗传算法求解模型,计算结果显示该模型减少了车辆的排放,有效地缓解了城市信号交叉口处车辆排放不易消散的问题.

| Abstract: | A comprehensive index of emission and delay were taken into consideration of the signal tim- ing program at urban intersection. This article, firstly, for the emissions of the intersection will be different when the operating characteristic changed, came up with a method considering the intersec- tion operation characteristics and emission factors, obtain the emission model of the vehicle at the in- tersection. Then, a optimal controlled model was established. On the basis of it, and the model was calculated with the help of the improved genetic algorithm. The calculations show the significantly re- duce of vehicle emissions, which alleviate the uneasy dissipated problem of the vehicle emissions at ur- ban intersection. |
