摘　　要：基于二流理论,以四相位信号交叉口为研究对象,通过采集交通流数据构建当量长度模型,将计算出的当量排队长度作为信号交叉口自适应控制的依据。最终,进行模糊综合评价,通过选取三个评价指标(车均延误时间、饱和度、排队长度)对某一四相位信号交叉口实施的自适应控制方案前后进行对比,验证此方案的合理性。Based on the two-fluid theory, the four-phase signalized intersection is choosen as the research object. The equivalent length model is constructed by collecting traffic flow data, and the calculated equivalent queue length is used as the basis for adaptive control of signalized intersection. Finally, the fuzzy comprehensive evaluation is carried out, and the adaptive control schemes implemented by a four-phase signalized intersection are compared before and after the three evaluation indicators (vehicle delay time, saturation, and queue length) are selected to verify the rationality of the scheme.
