城市快速路建设的目的是为了缓解城市的交通拥堵,提高车辆的行驶速度。匝道控制是缓解快速路交通拥堵的有效方法之一,在国内外受到了许多学者的青睐。文中根据以往的经验,对经典的入口匝道控制方法进行分类研究:依据对实时信息响应的不同分为静态控制与协调控制;并在此基础上进一步根据控制范围的不同分为单点控制与协调控制。文中将对几种常见的方法进行总结分析,指出他们的优缺点和适用条件。
The purpose of the construction of urban expressways is easing the city’s traffic congestion and improving the speed of vehicles. On- ramp metering is an effective way to ease road traffic congestion,favored by many scholars both at home and abroad. Based on the past experience,we will learn the on- ramp metering classically: depending on the responsing to real-time information,they are divided into static- control and dynamic- control; and on this basis,depending on the control range divided into single- point control and dynamic control further. This paper will summarize several common methods,points out their advantages,weaknesses and conditions.
