协调控制子区快速动态划分方法研究

In this paper, dynamic division of coordinated control subarea is realized by establishing the division model of control subarea with correlation degree theory and designing the process of searching for optimal subarea division scheme. Aiming at the problem of dimension disaster probablely existing in searching for optimal subarea division scheme, we present dimension-reduced processing and genetic algorithm to realize the fast optimization of subarea division. A fast dynamic division process of coordinated control subarea is proposed in detail. The example demonstrates that the fast dynamic division method of control subarea can search a sub-optimal solution with high probability under a certain scale network, and finish the optimization process in designated time. Therefore, this fast dynamic division method can satisfy the real-time request of control subarea division effectively, and can be applied to the real-time urban traffic signal control system.
