摘要： 提供了一种基于单层分布式MAS 结构的智能交通信号灯控制系统模型，系统中每一个Agent 根据本地交叉路口的交通状况自主形成控制策略，并将该策略与其他的Agent 进行协商，以实现整个系统的自适应控制。为了验证本研究的结果，用Java 开发了TSCSNHM模拟器，并在其中使用KQML 语言实现各个Agent 之间的信息交换和协商。通过3 种典型的控制模式的模拟实验结果表明，TSCSNHM 模式的控制效能接近于集中智能控制模式。

Abstract: This paper presents a novel approach using non-hierarchical distributed MAS in urban intersection traffic signal control. It is called traffic signal control system based non-hierarchical MAS (TSCSNHM). In the model, each agent plans pattern of signals according to it local traffic status for the intersection it responds. But the patterns must be negotiated with neighboring agents before being implemented. By this means, bigger area effectively control can be achieved. It uses a simulator to validate the idea. This simulator is programmed by Java, and uses KQML to implement communication and negotiation between agents. To contrast with the approach, this paper uses other two typical control methods, fixed-phase control model and centralized control model in simulation. The results of simulation show that TSCSNHM has excellent performance that is closed to centralized control model, and is more simple, flexible and robust than the latter.
