摘要 事件检测算法是事件管理系统的关键内容。利用神经网络和模糊逻辑结合系统进行事件检测是目前的研究热点 ,有两种形式 :模糊神经网络和模糊逻辑———神经网络协作系统 ,本文提出了基于模糊逻辑和径向基函数网络协作系统的事件自动检测算法 ,用径向基函数网络描述模糊逻辑 ,综合两者的优点。为了反映交通检测参数的相对变化 ,本文提出了新的交通流参数模糊化方法———二次高斯概率法。仿真数据表明 ,本文所提出的算法性能优越 。 Automatic Incident Detection(AID)is a crucial component of freeway traf fic management system.The combination of fuzzy logic and neural network,which i s a hot topic around the world,can be divided into two patterns:fuzzy neural ne t work and fuzzy logic-neural network collaboration system.The latter is favorite in this article,radial basis function network is used to realize fuzzy logic,a bs orbing the advantage of both sides.To reflect the relative variation of paramete r variables,a new method of fuzzification called quadratic Gauss-probability me t hod is brought forward.Simulation data shows that the algorithm presented in thi s paper is superior,and it is suitable for engineering.
