【摘要】 本文分三部分。第一部分在分析城市交通控制研究现状和平面交叉口控制原理、评价方法的基础上，提出了平面交叉口的模糊控制策略，并给出了其设计实例。第二部分通过对平面交叉口路口环境及车流到达、排队、跟驶、冲突、拐弯、驶离等各种运行状态的分析，建立了平面交叉口路口形状、路口信号控制方法及车辆各种运行规律的数学模型，并给出了基于二维动画界面的平面交叉口交通流通用仿真系统的设计方法和基本程序框架。最后一部分，用仿真系统对平面交叉口模糊控制方案进行仿真评价。结果表明，模糊控制优于传统的控制方法。更多还原

【Abstract】 This paper is composed of three parts. In the first part, on the basis of analyzing the city-traffic developments, the grade crossings control theory and its method of evaluation, the author presents a fuzzy control plan at the grade crossings and introduces its design method by a example. In the second part, by analyzing crossings environment and various vehicle operation states such as arrival, queuing, trace, conflict, turning, departing and so forth at the grade crossings, the author sets up the mathematical model of crossings shape, crossings control method and varioUs operation pattern of grade crossings and introduces the design method and basic programming frame of general traffic flow simulation system based on two dimensional animation. In the final part the fuzzy control plan at the grade crossings is checked and evaluated by simulation system. The result shows that it is superior to the conventional method.更多还原
