摘　　要：以车辆在行驶过程中的驾驶行为作为研究对象,对元胞自动机的概念、类型、结构以及他们在驾驶行为仿真中的应用进行了学习和研究。元胞自动机实现方法简单,仿真效率高,但无法描述车辆在拥有不同类型驾驶员情况下的行为决策过程,导致所有车辆的驾驶行为都服从同一规则;模糊控制能够描述不同交通元素的特性和自主行为,但实现复杂。根据元胞自动机和模糊控制的这些特点,设计了将元胞自动机和模糊控制理论相结合的方法,既保持了元胞自动机在仿真应用中的优点,又结合模糊控制理论反映了车辆驾驶行为的自主特性,并通过动态仿真验证了方法的可行性。This paper discusses vehicle driving behaviors.The concepts,types,structures and applications of cellular automata in driving behavior simulation were studied.Cellular automata is simple to be realized and has higher efficiency,but the decision process of vehicles which have different types of drivers can not be described,and fuzzy control can reflect the characters of different complex traffic elements,but its realization is complex and has lower efficiency.According to these features of cellular automata and fuzzy control,a combination of cellular automata and fuzzy control was designed.This method not only keeps the advantages of cellular automata in simulation but also reflects the autonomous characters of vehicle driving behaviors.The feasibility of the method was verified by the dynamic simulation.
