摘要“绿波带”是指在某一路段，车辆以一定的速度行驶，若在第一路口遇到红灯，之后路口遇到全是绿灯；若在第一路口遇到绿灯，之后路口遇到也全是绿灯，犹如行驶在一条畅通无阻的绿色屏带中，故名绿波带。65010
LabVIEW是一种用图标代替文本进行创建应用程序的图形化编程语言。本次研究主要用LabVIEW软件编一个程序，实现连续三个路口可调节的绿波带。根据课题要求,本文首先分析了绿波带的实际应用及发展状况，然后重点分析了基于LabVIEW软件的交通信号灯绿波带设计过程，通过使用case结构、for循环等函数控件，运用商与余数的基本算法，实现红绿灯的倒计时控制，程序中定时计数可人为设定，灵活的人机交互方式充分发挥了虚拟仪器软件的特点。
然后本次研究运用了软硬件结合，通过PXI平台来模拟三个路口绿波带的运行情况。实验结果验证了本设计的正确性。

Title Design of The Traffic Lights Green Wave Based on LabVIEW
Abstract
When driving on a section of highway with a certain speed, and if it encounters a red light at the first intersection，then there will be green lights at all the remaining intersections. Also if it is a green one at the first intersection, there will be green lights at the rest of the intersections too. It likes driving in an unimpeded green screen. So it names Green Wave. LabVIEW is a graphical programming language, and it creates applications by using icon to replace text. This research will focus on using LabVIEW to create a program. The program will help achieving the aim that the green wave area of any three continuous intersections can be adjusted. According to the requirements, this paper will first analyze the application and development of the green wave area. Then it will pay emphasis on the designing processes of traffic lights green wave area which is based on LabVIEW. By the application of function control like case-structure & for-loop, and the quotient & remainder basic computing, the countdown control of traffic lights can be achieved. Moreover, the timing counts are artificial and the HCI mode makes the virtual instrument software more flexible.
This research takes advantage of both hardware and software. And the PXI platform comes into use when the operation condition of green wave area of three continuous intersections is been simulated. Experimental results verify the correctness of this design.
