基于粗糙集的相邻交叉口信号控制方法研究

复杂交通区域的交通状况难以利用具体模型直接描述，而粗糙集理论能够在分析大量经验数据的基础上找到用于决策的规则。以交大东路上的行人和机动车为研究对象，提出一种基于粗糙集的信号配时算法，对交大东路上的两个相邻交叉口的信号灯进行控制，提出控制规则，对该复杂交通区域进行优化和疏导，是对多交叉口交通管理与控制的一次有益尝试。

Adjacent Intersection Signal Control Based on Rough Set

It′s difficult to accurately describe the traffic condition in complex traffic areas using specific formulas. But by analyzing plenty of data based on rough set theory, rules can be found for decision-mak-ing. The article put pedestrians and vehicles on Jiaoda-East Road as the research object, and then pre-sented with a signal algorithm based on rough set to control two neighboring traffic lights in the road and reduce traffic pressure in this complex traffic area. Finally, it proposed control rules and guidance to opti-mize the complex traffic area, which was a beneficial trial for multiple intersections group on traffic man-agement and control.
