摘要: 将高速公路中通道控制的概念应用于城市道路, 研究了这种控制模式在城市中的应用范围, 讨论了通道控制策略, 采用总行程时间作为控制变量, 分别推导了总行程时间的各组成部分, 并建立总行程时间最小控制策略下的通道控制数学模型和控制流程。数值算例结果表明: 采用总行程时间最小为控制策略的城市交通通道控制方法, 可使系统达到最佳。

Abstract: The corridor control model, which is usually used in freeway, was adopted to urban road control. Its applying situation and control strategy were analyzed when the total travel time was taken as control parameter. The constitute parts of total travel time were seperated. The minimization of total travel time as a control goal, its mathematical model and control program were developed. With an example, the results show that this control technology is an effective way to make the control system optimum,
