交叉口混合控制及其切换方法

针对交通控制中时段划分的主观性,根据Fisher最优分割原理,实现了时段的科学有效的划分;利用时段划分结果,采用混合控制方法对交叉口进行控制并给出了混合控制的平稳切换方法,实验表明相比感应控制和定时控制,该方法平均延误、排队长度、平均停车次数都得到了显著改善。

A Hybrid Control of Intersection and Its Switch Method

To avoiding the warp being at the traditional method, a traffic intervals partition method based on sequential clustering was presented. According to the Fisher optimal dissection method, traffic intervals partition was realized effectively and scientificly; one hybrid control strategy and its switch way is proposed based on traffic intervals partition. Compared with actuate signal control and static period control, the result shows that the average delay, queue length and average stop time of this method have been improved significantly.
