快速路出口匝道交织区交通组织方法研究

Research on Traffic Organization Method of Expressway Exit Ramp Interweaved Area

城市快速路出口匝道与下游交叉口归纳成3种交通组织方法,即常规交织布置、车道转向置换及交替放行控制。利用微观交通仿真软件进行回归分析,提出城市快速路典型衔接交织段的延误计算公式,可对交织区运行延误进行量化计算。最后结合工程实例对3种方法的运行效果进行比较,提出快速路出口匝道设计和管理的方法。

There are three traffic organization methods for urban expressway exit ramp&downstream intersection,namely conventional weaving arrangement,lane change&alternate release control.By regression analysis with micro traffic simulation software,the delay calculation formula of typical connecting weaving section of urban expressway is proposed,which can be used to quantify the operation delay of weaving section.Finally,it compares the operation effects of the three methods with an engineering example,and puts forward the control&management methods of expressway exit ramps.
