基于城市区域路网的分散协调控制研究

根据城域多路口交通系统的特点,摒弃统一信号周期的方法,以各单路口为基点,采用分散协调控制策略,综合考虑各相邻路口及两路口间的交通流,实时控制各路口交通信号,并智能的加以协调,使区域内道路的交通通行能力得到提高,降低车辆的延误时间。为提高系统的控制精度和鲁棒性,采用神经网络技术实现模糊控制。仿真结果表明,该方法控制效果良好。

Study on decentralized coordinated control based on urban traffic network

According to the characteristics of Urban Multi-intersection and each single multiphase signalized intersection,a novel distributed and cooperative control algorithm is designed based on urban traffic road net taking into consideration of the vehicle information of each intersection and inter sections.The proposed controlling model can improve the traffic conditions and reduce the vehicle delay time.Neural network is proposed to fuzzy control,the system has high control precision and the merit of robust characteristic.The computer simulation showed that the developed controller works with good performances.
