针对匝道等待时间描述中存在信息缺失的问题,结合排队论提出了一种新的冗余等待时间概念并建模分析.以此为基础,给出了匝道多目标协调控制方程,并以径向基为核函数设计了一种基于支持向量机的匝道控制律求解方法.利用高速公路联络线转向城市快速路的高峰时段实例数据进行仿真.实验结果表明,与其它控制方法相比,所提的模型和算法在描述匝道状态和规避冗余等待等方面的效果更优.
Aiming at the problem of lack of information in the description of ramp waiting time, a new concept of redundant waiting time and modeling analysis are proposed based on queuing theory.On the basis of this, a ramp multi-objective coordinated control equation is given, Based on the kernel function, a control algorithm based on support vector machine is proposed to solve the ramp control law. The simulation is made by using the example data of the highway connecting line to the urban expressway during rush hour. The experimental results show that compared with other control methods, Models and algorithms are better at describing ramp conditions and avoiding redundant waiting.
