Distributed cooperative control of road network traffic based on multidisciplinary design optimization

城市路网交通控制直接影响着交通运行效率,对其优化研究已成为缓解城市交通拥堵问题的热点之一.鉴于此,针对高峰交通路网将其分为过饱和区域与过饱和关联区域,在采用灰色关联分析-谱聚类方法对关联区域划分的基础上,构建路网交通分布式协同控制模型,进一步提出基于多学科设计优化的过饱和区域及其关联区域协同优化求解方法.通过搭建实例路网模型分析算法优化效果,结果表明所提出方法能够明显改善路网交通运行效率,有助于缓解城市通勤高峰时段的交通拥堵和扩散问题.

Traffic control of urban road networks has a direct impact on the efficiency of traffic operation, and its optimization research has become one of the hotspots to solve the problem of urban traffic jam. In this paper, the peak traffic network is divided into oversaturated region and its associated areas, and the grey relational analysis and spectral clustering method are used to divide the associated areas. Then, a distributed traffic cooperative control model is proposed. Furthermore, a cooperative optimization solution of over-saturated region and its associated areas based on multidisciplinary design optimization is proposed. The optimization results of the algorithm are analyzed by setting up an example network model. The results show that the proposed method can significantly improve the traffic efficiency of the road network, and help to alleviate the traffic congestion and proliferation during rush hour.
