高速公路互通式立交入口区是影响立交整体运行的关键点段,为了减轻入口合流区的拥挤、提高高速公路互通式立交的整体效率、提高车辆行驶的安全性,在交通需求增大到一定程度时,要采用一些交通管理控制措施。根据互通式立交匝道入口区域的特点,本文对高速公路网可靠性作用较大的互通立交匝道和主线的管理控制策略进行了研究。分析了入口合流区的几何和交通特性,对匝道和主线分别提出了不同管理控制策略,即:高速公路匝道入口控制策略和主线车道运行约束策略。
Expressway interchange interchange zone is the key point affecting the overall operation of interchange. In order to reduce the congestion of entrance confluence area, improve the overall efficiency of express interchange and improve the safety of vehicle driving, when traffic demand increases to a certain extent When to adopt some traffic control measures. According to the characteristics of the interchange zone of interchange, this paper studies the management and control strategy of interchange and main line of interchange with greater reliability of expressway network. The geometric and traffic characteristics of entrance confluence area are analyzed, and different management control strategies are proposed for ramp and main line, respectively: control strategy of freeway ramp entrance and main lane traffic restraint strategy.
