Description: 十字路口车辆穿梭，行人熙攘，车行车道，人行人道，有条不紊。那么靠什么来实现这井然秩序呢？靠的是交通信号灯的自动指挥系统。交通信号灯控制方式很多。本设计主要分为五大模块输入控制电路、时钟控制电路、片内外程序切换控制、显示电路。以MSC-51系列单片机IntelAT89C51为中心器件来设计交通灯控制器，实现了AT89C51芯片的P0口设置红、绿灯、黄灯燃亮时间的功能；为了系统稳定可靠采用了74LS14施密特触发器芯片的消抖电路，避免了系统因输入信号抖动产生误操作；显示时间直接通过AT89C51的P2口输出，由CD4511驱动LED数码管显示红灯燃亮时间。-The intersections vehicle wears shuttle, pedestrian Xi Rang, garage driveway, person s sidewalk, orderly. So depend what to carry out this well arranged order? What to depend is a traffic sign light of automatic conductor system. The control method of the traffic sign light is a lot of. This design is mainly divided into five greatest molds a piece the electric circuit, clock of the importation control a control outside procedure inside the electric circuit, slice to cut over a control and shows electric circuit. Take single slice the machine IntelAT89 C51 of the serieses MSC-51s as a center spare part to design transportation light controller, carried out the AT89 C51 s P s 0 people s constitution of the chips red, the function in bright time of green light, Huang2 Deng Ran2 For the sake of system stability the credibility adopted a 74 LS14 airtight trigger eliminate of machine chip to tremble electric circuit especially, avoided system because of importation the signal tremble movabl

Description: 采用模糊控制的思想，实现交通路口红绿灯时间的优化控制。
功能要求：(1) 采用模糊控制实现红绿灯控制，根据车流量的不同来控制红绿灯的显示时间。
(2) 模拟实际交通路况，简化编程难度，只考虑横竖方向的车流量，并不考虑车的拐弯，重点突出模糊控制算法
-Using fuzzy control theory to achieve the traffic intersection of time optimal control of traffic lights. Functional requirements: (1) using fuzzy control to achieve traffic light control, according to the different traffic flow to control the traffic lights display the time. (2) simulate the actual traffic and road conditions, simplify programming difficulty, only if they had to consider the direction of traffic flow, without considering turning vehicles, focused fuzzy control algorithm
