摘　　要：红绿灯是现代化社会中必不可少的交通指挥工具。本文通过微元法,通过合理的假设,对此红绿灯对车流量的影响做了初步的研究,得出了红灯绿灯时间的长短对车流量影响的函数关系。通过合理的选择一个能使两个路口都能进行初始化的时间,即可得出较为合理的红绿灯时间。Traffic light is indispensable in traffic controlling system. The research is about the influence of traffic lights on the traffic by using the method of Infinitesimal. We have eventually gotten a function between traffic and the duration of the traffic lights. Furthermore, we can ealeulate the optimal duration of the traffic light based on the results of the research.
