摘要
阐述了高速公路运行中存在的主要问题,分析了可变限速控制在高速公路监控系统中所起到的作用。给出了主线可变限速控制的原理和控制策略,并建立了相应的数学模型。针对高速公路交通流的特点,采用多层分散控制的策略,实现对主线行车速度的控制。仿真结果表明了模型和控制策略的有效性。
The critical problem in highway systems was discussed, and action of the main variable speed-limit control of the surveillance and control system of highway was analyzed. The principle and strategy of the main variable speed-limit control are presented, and the mathematical models are proposed. According to the feature of traffic flow of highway, multilayer decentralization controlling strategy was adopted in order to realize the speed control in the main highway. The simulation shows that validated the models and control strategy are validated.
