高速公路界壳论及应用

Jieke Theory of Freeway and Its Application

运用界壳论,分析了高速公路系统界壳要素——界门、界壁的主要特征,定义了界壳交换速率、界壳开放度、界门顺利度、界门开关速度以及界壁抵抗力等描述高速公路界壳功能的参数.建立了以高速公路界壳交换速率为开关函数的入口匝道关闭控制开关模型,分析了界壁抵抗力函数在高速公路事件管理中应用的可行性,提出了界壳总调控模型在高速公路系统优化控制中的应用思路.研究表明:界壳论在高速公路事件管理、入口匝道控制及系统优化控制等方面具有应用前景.

The principles and methods of Jieke theory are used to analyze characteristics of main factors of the freeway Jieke,and the parameters describing the function of freeway Jieke,such as exchange rate,open ratio,smooth degree and switch speed of Jieke gate,as well as resistance of Jieke wall are defined.In addition,the switch model of on-ramp control used the exchange rate of Jieke as the switching function is established,the feasibility of applying the resistance function of Jieke wall in the incident management of freeway is analyzed,and the idea using the total control model of Jieke to system-optimal control for freeway is presented.The research shows that the theory of freeway Jieke can be applied well in incident management,on-ramp control and system optimal control.
