城市平交路口立交化改造研究

Study on Reformation for Grade Separated Interchange of Urban Road Grade Crossing

从平交路口通行能力、交叉口饱和度两个常用的交叉口运行状况评价指标分析入手,在确定各方向车道服务水平的基础上,根据交叉路口所处城市密度的区位,即可综合确定平交改立交的可行性。

Through analyzing the two common evaluation indexes of intersection traffic condition, consist of intersection traffic capacity and intersection saturation degree, and on the basis of determining service level of each directional traffic line, the feasibility of grade crossing be separated can be determined comprehensively according to the position of grade crossing in the urban density area.
