[摘要] 道路十字路口是城市道路网的咽喉要道,其通行能力制约着城市道路的通达，是交通的重中之重，交叉口的存在,提高了人们出行的通达水平,改善了路网的连通性。但在交叉口处,不同方向车辆的交叉运行,极易造成交叉口处车辆运行效率的下降，如何提高十字路口的通行效率是城市道路问题的关键。研究道路十字路口的交通问题有助于充分利用交叉口的时空资源,降低或消除其对道路系统的瓶颈影响,提高整个道路系统的通行能力和服务水平。通过对十字路口通行情况进行仿真，可以为道路管控者提供一个比较准确的智能模拟平台，以方便其了解十字路口状况，并且针对十字路口的特点，提出自己的解决办法。本系统设计、制作了系统硬件电路，然后对系统软件进行了设计，对交通的控制采用智能化的处理，用模糊程序实现了对道路情况的最合理的控制，对于环保和对道路的合理利用有一定的作用。由于时间和资金的条件限制，本设计略有不足之处，但总体上实现了设计思想。总体设计包括以下几个部分：主程序、模糊子程序、时间和信号灯的现实子程序以及语音子程序。系统软件和硬件联调成功，效果良好。

[Abstract] The road intersection is the throat road of the city road network, and its traffic capacity restricts the access of the city road, is the most important traffic, the intersection of the existence of the people to improve the level of access to improve the connectivity of the road network The But at the intersection, the cross direction of the vehicle in different directions, can easily lead to the intersection of the vehicle operating efficiency decline, how to improve the crossroads of traffic efficiency is the key to urban road problems. Studying the traffic problems at the crossroads of the road will help to make full use of the temporal and spatial resources of the intersections, reduce or eliminate its bottlenecks to the road system, and improve the capacity and service level of the whole road system. Through the simulation of traffic at the crossroads, it is possible to provide a more accurate intelligent simulation platform for road managers to facilitate their understanding of the situation at the crossroads and to propose their own solutions to the characteristics of the crossroads. The system design and production of the system hardware circuit, and then the system software was designed to control the use of intelligent traffic control, with fuzzy procedures to achieve the most reasonable control of the road conditions for environmental protection and reasonable use of the road Have a certain effect. Due to the constraints of time and capital, the design is somewhat inadequate, but the overall design ideas. The overall design includes the following parts: the main program, fuzzy subroutine, time and signal of the reality of subroutines and voice subroutine. System software and hardware joint success, the effect is good.
