對目前交通控制現狀進行深入分析與調研的基礎上,設計出了一個較為完善、功能強大的十字路口交通燈控制系統。該智能交通燈控制系統由51單片機、LED信號燈以及雙位共陰極數碼管、紅外計數模塊、蜂鳴報警模塊等組成。系統除實現基本交通燈的倒計時以及信號切換功能外,還可通過按鍵切換不同的模式,如實現夜晚慢行模式、禁行模式、優先緊急車通過、違規報警等模式,經仿真驗證該系統具備車流量檢測及調整、闖紅燈判斷及處理等相關功能。該設計能夠實現預期控制目標,提高交通道路的通行效率。

Based on an in-depth analysis and investigation of the current traffic control situation,a relatively complete and powerful crossover traffic light control system is designed in this article.The intelligent traffic light control system is composed of 51 single chip microcomputer,LED traffic light and two-bit cocathode digital tube,infrared counting module and buzzer alarm module.In addition to realizing the countdown of basic traffic lights and signal switching functions,the system can also switch different modes through buttons,such as realizing the night slow mode,forbidden mode,priority emergency vehicle passage,and illegal alarm,etc.It is verified by simulation that the system has the related functions such as vehicle flow detection and adjustment,red light running and processing.The design can achieve the expected control goal and improve the traffic efficiency of the road.
