高速公路可变限速控制算法研究

On Variable Speed-Limit Control Algorithms of Expressways

高速公路可变限速控制是减少拥挤和事故发生的有效方法,是近年来高速公路研究领域的热点.对高速公路可变限速控制算法进行综述分析,根据控制区域的不同将算法分成主线可变限速控制和主线与匝道可变限速协调控制两大类,从这两大类算法出发,分别总结不同算法的应用现状,指出目前研究中存在的主要问题,结合最新成果对未来研究的方向进行分析.

The variable speed-limit control is an effective way to reduce congestion and accident on expressways. And it has become a research hotspot in the field of highways in recent years. The control algorithms are summarized and analyzed. The algorithms are divided into two aspects according to the different control regions. Respectively from two aspects, the status quo of application of VSL control algorithms on highways are summarized, and the main problems of present studies are pointed. Combined with the latest research results, the development direction in the future is analyzed.
