The result indicates that the proposed method can greatly improve the traffic condition compared with the traditional fixed - time control method . 4 . based on the signal control of the isolated intersection , a dynamic optimization and control method for urban artery is presented , whose objective is to maximize the throughput of artery system during the whole control period 在單交叉路口信號動態(tài)優(yōu)化控制研究的基礎(chǔ)上,針對飽和交通干線的信號控制問題,提出了以控制周期內(nèi)飽和交通干線系統(tǒng)的車輛通行量最大為目標(biāo)的交通信號動態(tài)優(yōu)化控制方法。
