摘　　要：针对混合交通流下交通秩序混乱、通行效率低下及事故安全等问题,本文依据智能交通的相关原理,结合"机非共存"的思想,以矢量物模型作为统一微观模型,以机动车跟车模型为基准,完成了混合交通流下的机非干扰建模;同时应用模糊控制方法实现了对交叉口信号的智能化控制,并通过Matlab进行了仿真实验,结果表明其能够提升交通运行效率、降低事故发生率。Aiming at the problems such as the disorder of traffic order,the low traffic efficiency and the safety of accident,etc,in this paper,according to the intelligent traffic theory,combined with the idea of＂finders coexistence＂,to take the vector model as a unified microscopic model,and vehicle car following model as a benchmark to constract a traffic network; moreover,it applied the fuzzy control method to realize the intelligent control of intersection signal,and make a simulation experiments by the Matlab,the results show that it can improve transport efficiency,reduce the rate of accidents.
