摘 要：汽车普及让人们聚焦交通安全，十字路口作为交通事故发生频繁地段，对十字路口交通灯系统设计的优化升级越来越引人关注。LabVIEW是技术前沿的设计平台，具有易操作、实用性强等优点。本文选用LabVIEW为操作平台，针对小型十字路口的路面状况，构建一个基于LabVIEW的交通灯模拟系统。系统除了能满足车行道的需求外，还针对人行道这一实际情况，对交通灯控制系统做了一定改进和优化，通过数码管显示倒计时和模块化设计的原则，进一步完善和优化小型十字路口交通灯系统。

【Abstract】：The popularization of automobiles allows people to focus on traffic safety， crossroads are areas where traffic accidents occur frequently， the optimization and upgrading of the design of the intersection traffic light system is attracting more and more attention. LabVIEW， as a design platform at the forefront of technology， has the advantages of easy operation and strong practicability. The paper chooses LabVIEW as the operating platform to construct a traffic light simulation system based on LabVIEW in view of the pavement conditions of small intersections. In addition to meeting the needs of the roadway， the system has also made certain improvements and optimizations to the traffic light control system for the actual situation of the sidewalk， through the digital tube display countdown and the principle of modular design， the small-scale intersection traffic light system is further improved and optimized.

【Key words】：LabVIEW; Traffic light; Sidewalk
